A protocol for controlled reactivity shift in the 2,2-difluorovinyl motif used for selective S-18F and C-18F bond formation.

Positron emission tomography (PET) is a powerful imaging technique for biomedical research, drug development and medical diagnosis. The power of PET lies in biochemically selective radiotracers, labelled with positron emitters like fluorine-18 image chemical processes in vivo. A rapid and remarkably efficient, unprecedented protocol to select between S-F and C-F bond formation based on activation of 1,1-difluoroethylene groups followed by selective oxidation or reduction is described. While transition metal mediated conditions can be employed, the reaction proceeds in high yield using unobjectionable chemical reagents amenable to routine radiotracer production. The latter bodes well for facile clinical translation of the method. The new technique affords radiotracers and the labelling reagent 2,2-difluoro-2-(fluoro-18F)ethyl 4-methylbenzenesulfonate ([18F]1b) in excellent yield. Following oxygenation of the reaction mixture with medical oxygen or air, sulfonyl fluorides are obtained as the primary product. The new protocol was employed in a proof of principle to develop a radiometric assay for quantitation of sulfonylation yield with sulfonyl fluoride reagents. With operational ease and mild conditions, the method bodes a high potential for radiolabelling of biomolecules, known enzyme inhibitors and other temperature-sensitive compounds.

Synthetic and Natural Bioactive Molecules in Balancing the Crosstalk among Common Signaling Pathways in Alzheimer's Disease: Understanding the Neurotoxic Mechanisms for Therapeutic Intervention.

The structure and function of the brain greatly rely on different signaling pathways. The wide variety of biological processes, including neurogenesis, axonal remodeling, the development and maintenance of pre- and postsynaptic terminals, and excitatory synaptic transmission, depends on combined actions of these molecular pathways. From that point of view, it is important to investigate signaling pathways and their crosstalk in order to better understand the formation of toxic proteins during neurodegeneration. With recent discoveries, it is established that the modulation of several pathological events in Alzheimer's disease (AD) due to the mammalian target of rapamycin (mTOR), Wnt signaling, 5'-adenosine monophosphate activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α), and sirtuin 1 (Sirt1, silent mating-type information regulator 2 homologue 1) are central to the key findings. These include decreased amyloid formation and inflammation, mitochondrial dynamics control, and enhanced neural stability. This review intends to emphasize the importance of these signaling pathways, which collectively determine the fate of neurons in AD in several ways. This review will also focus on the role of novel synthetic and natural bioactive molecules in balancing the intricate crosstalk among different pathways in order to prolong the longevity of AD patients.

Teenage menstrual dysfunction: an overview.

When a girl experiences her first period, she starts a new phase of her life and becomes biologically capable of becoming a mother and giving birth to a child. Girls' hypothalamus-pituitary-ovary axis reaches "axial maturity" during puberty, when they are between the ages of 8 and 13 years old. Secondary biological features, including as growth, body-shape changes in females, breast growth, hair growth on the vulva, and hair growth on the axillary pits, are often observed during this era. The first menstruation, or menarche, is also commonly observed during this time. During the menstrual cycle, a woman's ability to conceive and give birth is at the core of her reproductive life.

Unfolding the mystery of premenstrual syndrome (PMS): an overview.

Physical, emotional, and psychological symptoms are common among women in their reproductive years, particularly during their menstrual cycle's luteal phase and the week before their period. Approximately 5-8 percent of women suffer with premenstrual syndrome, with the majority of those suffering from premenstrual dysphoric disorder (PMDD). Because of the complexity and multifaceted nature of the aetiology, it is yet unknown. Premenstrual syndrome (PMS) is diagnosed entirely on the basis of signs and symptoms, with no particular diagnostic tests available to confirm the diagnosis. Only a small number of therapeutic modalities are backed by clinical data, yet there are many accessible. After providing a brief overview of the disease, the author goes on to discuss the various hypotheses as to why PMS occurs. With an emphasis on tailored treatment based on symptom profile, it examines the wide range of non-pharmacological and pharmaceutical methods that are accessible today.

A Comprehensive Review on Journey of Pyrrole Scaffold Against Multiple Therapeutic Targets.

Heterocyclic compounds are that type of substances that are deeply intertwined with biological processes. Heterocycles are found in about 90% of commercially available medicines. In medicinal chemistry, finding new synthetic molecules with drug-like characteristics is a regular problem, which triggered the development of pharmacological molecules, the majority of which are based on N-heterocyclic motifs. Among the heterocycles, the pyrrole scaffold is the most commonly found heterocycle in both natural and synthetic bioactive compounds. Pyrrole has a fivemembered heterocyclic ring with a plethora of pharmacophores, resulting in a library of different lead compounds. Pyrrole derivatives are physiologically active heterocyclic compounds that can be used as scaffolds for antibacterial, antiviral, anticancer, antitubercular, anti-inflammatory, and as enzyme inhibitors. On account of their extensive pharmacological profile, pyrrole and its various synthetic derivatives have drawn much attention from researchers to explore it for the benefit of humankind. This review presents an overview of recent developments in the pyrrole derivatives against multiple therapeutic targets.

Treatment Strategies Against Triple-Negative Breast Cancer: An Updated Review.

Triple-negative breast cancer (TNBC) is associated with an increased risk of early recurrence and distant metastasis, as well as the development of therapeutic resistance and poor prognosis. TNBC is characterized by a wide range of genetic, immunophenotypic, morphological, and clinical features. TNBC is coined to describe cancers that lack estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). As a result, hormonal or trastuzumab-based treatments are ineffective in TNBC patients. TNBCs are biologically aggressive, and despite some evidence that they respond to treatment better than other forms of breast cancer, the prognosis remains poor. This is attributed to a shorter disease-free interval in adjuvant and neoadjuvant settings, as well as a more aggressive metastatic course. TNBC has a lot of clinical ramifications. In terms of new treatment methods, TNBC has lagged behind other types of breast cancer. There are not many options for treating this form of breast cancer because it is progressive. Many effective treatments for most breast cancers block the growth-stimulating effects of ER, PR, and/or HER2, leaving TNBC with few choices. Finding new and effective treatment options for TNBC remains a critical clinical need. To develop more effective drugs, new experimental approaches must be tested in patients with TNBC.

An up to date on clinical prospects and management of osteoarthritis.

The rising prevalence of osteoarthritis (OA) in the general population has necessitated the development of novel treatment options. It is critical to recognize the joint as a separate entity participating in degenerative processes, as well as the multifaceted nature of OA. OA is incurable because there is currently no medication that can stop or reverse cartilage or bone loss. As this point of view has attracted attention, more research is being directed toward determining how the various joint components are impacted and how they contribute to OA pathogenesis. Over the next few years, several prospective therapies focusing on inflammation, cartilage metabolism, subchondral bone remodelling, cellular senescence, and the peripheral nociceptive pathway are predicted to transform the OA therapy landscape. Stem cell therapies and the use of various biomaterials to target articular cartilage (AC) and osteochondral tissues are now being investigated in considerable detail. Currently, laboratory-made cartilage tissues are on the verge of being used in clinical settings. This review focuses on the update of clinical prospects and management of osteoarthritis, as well as future possibilities for the treatment of OA.

Acute neurological conditions during pregnancy and their management: a review.

Less vascular resistance, higher vascular permeability and improved cardiac output include anatomical and physiological changes related to pregnancy. These are needed to accommodate an increase in plasma volume and ensure significant organ infusion. Nevertheless, increases in oestrogen levels may lead to an increase in the risk of coagulation and thrombosis. Increased levels of progesterone increase the risk of thrombosis due to vasodilation, vascular stasis and edoema in these situations. The increased resistance in preeclampsia maternal systemic blood arteries can create high blood pressure that can interfere with blood flow in numerous organs (including liver, kidneys, brain and placenta). The risk of issues such as pulmonary edoema, placental abruption, pneumonia of aspiration, renal failure, hepatic failure and stroke in pregnant women is increased by Preeclampsia and eclampsia. Some peripheral neuropathies (carpal tunnel syndrome, peripheral facial palsy) and central neurological conditions (seizure, migraine, stroke, epilepsy) may become more common during pregnancy because of the exacerbation of the pre-existing neurologic condition or the onset of neurological disturbance caused by pregnancy physiological changes (such as headache or vascular disorders). During the three trimesters of pregnancy, neurological disorders are both peripheral and central. Therefore, an early and correct diagnosis is required to improve pregnancy care, treatment and perinatal outcomes. The aims of this paper are to identify, define and manage the most prevalent peripheral and centrally occurring neurological disorders in the pregnancy.

Depression and anxiety in women with polycystic ovarian syndrome: a literature survey.

Polycystic ovarian syndrome (PCOS) is the most frequent endocrine disorder among women of reproductive age. Some of the indications and symptoms of PCOS include amenorrhoea, hirsutism, infertility, obesity, acne vulgaris and androgenic alopecia. PCOS is a crippling condition that affects a woman's identity, mental health and overall quality of life (QOL). In persons with PCOS, anxiety and sadness are assumed to be multifactorial. According to some specialists, physical symptoms like acne, hirsutism and obesity have been linked to psychiatric morbidities. Many aspects of it remain unknown, including its cause, progression throughout life, symptom spectrum and level of morbidity. PCOS is a complex disease that has an impact on many aspects of a person's health, including their mental health. Anxiety and depression are three times as common in PCOS patients as in non-PCOS people. Anxiety and depression symptoms are also more common and more intense in those with PCOS. There isn't enough research on the prevalence of anxiety and depression in patients with PCOS. It's unclear what causes persons with PCOS to be more anxious and depressed. It could be the result of PCOS symptoms, hormonal changes, or a combination of factors that are currently unclear. Our review article will help to highlight the most recent research on anxiety and depression in PCOS women.

Menstrual distress in females of reproductive age: a literature review.

Menstrual-related issues have significant public-health ramifications. Women who are having menstruation troubles should get their mental health checked by healthcare specialists. In young women, a menstrual-related condition has serious health implications. Young females who have menstrual issues miss job and school, and their behavioural and mental development suffers as a result. Depression and anxiety have an impact on women's menstrual periods in adults. Symptoms like as cramps, tiredness, backache, swelling abdomen, and painful breasts have also been described in women with menstrual misery. Menstrual distress has been shown to impair women's daily activities, as well as their reproductive and psychological health, according to research. Menstrual periods are frequently accompanied by a variety of unpleasant symptoms, such as premenstrual syndrome, which includes symptoms such as mild cramping and exhaustion. The severity of these symptoms, on the other hand, differs from woman to woman, depending on their health, food, way of life, and other factors. Women with menstrual-related issues have also reported smoking, alcohol intake, and an increase in hunger. Furthermore, young women experience emotional disturbances such as melancholy, restlessness, and despair. It is a sign of an atypical menstrual cycle if there is no cycle or if the bleeding is atypical or light. As a result, it is critical to maintain contact with a gynaecologist in order to detect any significant changes in a regular menstrual cycle.

Polycystic ovary syndrome and infertility: an update.

Polycystic ovarian syndrome is the most well-known endocrine condition among women of this generation (PCOS). Symptoms of hyperandrogenism, irregular menstrual periods, and insulin resistance are all traits associated with PCOS. In women with PCOS, the chance of having problems including infertility, insulin resistance, and type 2 diabetes increases. The PCOS board hopes to reduce body weight and insulin levels, restore fertility, control excessive hair growth on the body or scalp, re-establish the regular feminine cycle, and avoid misunderstandings. Insulin sensitizers have been one of the most common metabolic modulators, but their effectiveness has been sporadic. Insulin resistance, followed by thiazolidinediones, is central to the pathophysiology of PCOS, with metformin having nearly similar efficacy. In the management of PCOS, statins and incretins are newer therapies with obvious metabolic targets. Vitamin D, acarbose, and myoinositol are just a few of the reciprocal and optional clinical treatments that have been proved to be useful in the treatment of PCOS. The number of viable methods for dealing with PCOS-related infertility has increased as well. Despite the fact that clomiphene citrate (CC) has long been the gold standard for ovulation induction in the event of ovulatory infertility, aromatase inhibitors can induce ovulation with results that are nearly identical to or better than those reported with CC, aromatase inhibitors can cause ovulation with results that are nearly identical to or better than those reported with CC. Ovarian incitement conventions that intelligently utilize gonadotropins, gonadotropin-delivering hormone rivals, the approach of ovarian boring, and assisted conceptive advancements with in vitro oocyte development indicate an expanding level of therapeutic progress.

Correlation between obesity, gestational diabetes mellitus, and pregnancy outcomes: an overview.

Obesity has been identified mainly as a raise in the body's adiposity leading to prolonged overshoot of caloric intake over expenditure. Obesity has significant health-altering implications which have been shown to be implicated in the pathogenesis and progression of other diseases through its extensive physiological assaults. The prevalence of overweight and obesity has been an increasing epidemic worldwide. The number of obese births was even on the increase, with an increasing number of women of reproductive age registering as obese. Obesity is related to adverse perinatal outcomes and increased morbidity and mortality in pregnant women. The potential risk for multiple antenatal, postpartum, intrapartum, and neonatal complications is maternal obesity. Greater risk of developing Gestational Diabetes Mellitus (GDM), pregnancy induced hypertension (PIH), pre-eclampsia, risk of venous embolism, increased need for labor induction, and cesarean sections in the mother have been recorded in a comprehensive analysis of pregnancy complications associated with obesity. The link between obesity, gestational diabetes, and pregnancy outcomes will be briefly shown in this article.

Polycystic ovary syndrome and reproductive health of women: a curious association.

Reproductive health is a broad concept that encompasses mortality, morbidity, and quality of life associated with the reproductive system, mechanism, and incidents encountered at all ages by men and women. Orthodox Indian society finds the conversation on reproductive health to be a taboo and discourages open conversations about it. Polycystic ovary syndrome (PCOS) is a reproductive-age metabolic endocrine disorder found in females. Females suffering from PCOS are prone to reproductive, metabolic, and cardiovascular disorders. In this paper, we will systematically review about effect of PCOS on Reproductive Health of Women. The numerous electronic databases such as: BMJ, LANCET, PUBMED, Unicef Website, WHO Website and Google Scholar have been comprehensively searched for studies linked to PCOS, its various effects and effect on women's reproductive health. For additional analyses, we have reviewed reference lists of reviews and collected papers. The effects of PCOS on women's reproductive health have been verified by several scientific reports worldwide. PCOS is a hormonal condition, as per multiple reports, with the ability to lead to different outcomes. It still appears to be a common cause among females of infertility. An integral aspect of the treatment of this disease is the early diagnosis of long-term morbidities by effective screening tests. In the future, studies must concentrate on the missing holes in our growing perception of this disease. Several studies have confirmed that reproductive morbidity, including irregular uterine bleeding, abortion, miscarriage, and other risk of pregnancy during reproductive years, is associated with PCOS. PCOS is an amalgam of physiological and psychosocial dysfunction, not just an endocrine disorder.

Unravelling the potency of triazole analogues for inhibiting α-synuclein fibrillogenesis and in vitro disaggregation.

A series of triazole-based compounds was synthesized using a click chemistry approach and evaluated for the inhibition of α-synuclein (α-syn) fibrillogenesis and its disaggregation. Compounds Tr3, Tr7, Tr12, Tr15, and Tr16 exhibited good effect in inhibiting α-syn fibrillogenesis confirmed by Thioflavin-T assay and fluorescence microscopy and α-syn disaggregation confirmed by fluorescence microscopy. Molecular docking was used to understand the plausible mechanism of the test compounds for inhibiting the α-syn fibrillogenesis and to verify the in vitro results. Compounds Tr3, Tr7, Tr12, Tr15 and Tr16 showed good binding interactions with the essential amino acid residues of α-syn. The compounds which were found to be good inhibitors or disaggregators had no toxic effects on the SH-SY5Y cell line. These compounds have the potential to be developed as therapeutic interventions against synucleinopathies including Parkinson's disease and Lewy body dementia.

Quinoline carboxamide core moiety-based compounds inhibit P. falciparumfalcipain-2: Design, synthesis and antimalarial efficacy studies.

Targeting Falcipain-2 (FP2) for the development of antimalarials is a promising and established concept in antimalarial drug discovery and development. FP2, a member of papain-family cysteine protease of the malaria parasite Plasmodium falciparum holds an important role in hemoglobin degradation pathway. A new series of quinoline carboxamide-based compounds was designed, synthesized and evaluated for antimalarial activity. We integrated molecular hybridization strategy with in-silico drug design to develop FP2 inhibitors. In-vitro results of FP2 inhibition by Qs17, Qs18, Qs20 and Qs21 were found to be in low micromolar range with IC50 4.78, 7.37, 2.14 and 2.64 µM, respectively. Among the 25 synthesized compounds, four compounds showed significant antimalarial activities. These compounds also depicted morphological and food-vacuole abnormalities much better than that of E-64, an established FP2 inhibitor. Overall these aromatic substituted quinoline carboxamides can serve as promising leads for the development of novel antimalarial agents.
