Alnustone: A review of its sources, pharmacology, and pharmacokinetics .

Alnustone (4(E)-,6(E)-1,7-Diphenyl-hepta-4,6-dien-3-one) is a non-phenolic natural diarylheptanoid, which was first isolated and identified from the male flower of Alnus pendula (Betulaceae). It can also be isolated from Curcuma xanthorrhiza Roxb (Zingiberaceae) rhizomes and Alpinia katsumadai Hayata (Zingiberaceae) seeds. It was first synthesized through a five-step process from ß-phenyl propionyl chloride. In later years, new methods for synthesizing Alnustone were designed and performed with different yields. Due to the various therapeutic effects exhibited by alnustone like other diarylheptanoids, its biological activities such as antioxidant, antibacterial, and anti-inflammatory properties have been the subject of many studies. This article has reviewed different aspects of this valuable natural compound, including its natural and synthetic sources, therapeutic effects, and pharmacokinetics as a potential future therapeutic agent.

A Comprehensive Review of the Pharmacological Properties and Bioactive Components of Retama monosperma.

Retama monosperma L. (Boiss.) or Genista monosperma L. (Lam.), known locally as "R'tam", is a spontaneous and annual herb that belongs to the Fabaceae family. It is native to the Mediterranean regions, specifically in the desert areas and across the Middle Atlas in Morocco. This plant has been extensively used in folk medicine and it is rich in bioactive compounds, including polyphenols, flavonoids, and alkaloids. Current research efforts are focusing on the development of novel natural drugs as alternatives to various organic and non-organic chemical products from Retama monosperma. In addition, extract, and isolated compounds obtained from different parts of the chosen plant have been described to exhibit multiple biological and pharmacological properties such as antioxidant, anti-aging, anti-inflammatory, antihypertensive, anti-helminthic, disinfectant, diuretic, and hypoglycemic effects. The plant-derived extract also acts as an antimicrobial agent, which is highly efficient in the treatment of bacterial, viral, and fungal infections. Its antiproliferative effects are associated with some mechanisms, such as the inhibition of cell cycle arrest and apoptosis. In light of these assessments, we critically highlight the beneficial effects of the flowers, stems, seeds extracts, and isolated compounds from R. monosperma (L.) Boiss in human health care, industrial, and other applications, as well as the possible ways to be employed as a potential natural source for future drug discovery.

The Efficacy of Kohl (Surma) and Erythromycin in Treatment of Blepharitis: An Open-Label Clinical Trial.

INTRODUCTION: Blepharitis is a common and chronic form of eyelid inflammation. Blepharitis treatment aims to decrease symptoms through antibacterial effects. One of the most common treatments of eyelid diseases in traditional medicine is using kohl. This clinical trial aimed to investigate its efficacy as a complementary treatment in staphylococcal blepharitis through an open-label clinical trial. MATERIALS AND METHODS: Thirty patients were randomized to receive kohl in one eye contralateral and erythromycin ointment in another eye for 90 days. At baseline and after 90 days of treatment, symptoms, clinical signs, and side effects of treatments were recorded. Statistical analysis was carried out using SPSS software, version 19. RESULTS: Despite randomization, there was a significant difference between the intervention and control eyes in the baseline mean clinical score (intervention eye: 9.86 (2.95) and control eye: 4.30 (2.81), P < 0.001). The degree of reduction of related signs and symptoms in the eyes treated with kohl was significantly higher than that in the control group: (5.2 vs. 2.20, P < 0.001) for symptoms and (7.40 vs. 2.46, P < 0.001) for clinical signs. Cohen's d statistic for mean difference of sign and symptom was 2.4 and 1.75, respectively, indicating a very strong effect. CONCLUSION: The present study results demonstrated a significant improvement in blepharitis-related signs and symptoms. The degree of improvement in the eyes treated with kohl was much higher than that in the control eyes.

Effect of Artemisia extract on glycemic control: A systematic review and meta-analysis of randomized controlled trial.

BACKGROUND AND AIM: Animal and human studies have indicated anti-diabetic effect of Asteraceae. The present study aimed to systematically review and analyse randomized controlled trials assessing the effect of Artemisia extract on glycemic status in patients with impaired glycemic control. METHODS: Web of Science, Cochrane library, EMBASE and PubMed databases were searched from the earliest possible date up to 7th October 2020. RESULTS: Six studies were included in the meta-analysis. Analysis showed that supplementation with Artemisia extract decreased homeostatic model assessment of insulin resistance (HOMA-IR) (-0.734, 95% CI: -1.236 to -0.232, P = .019) in comparison to placebo. However, reductions in fasting blood glucose (FBG) (-0.595, 95% CI: -1.566 to 0.376, P = .164), insulin (-0.322, 95% CI: -1.047 to 0.404, P = .286) and glycated haemoglobin (-0.106, 95% CI: -0.840 to 0.629, P = .678) were not statistically significant. CONCLUSION: Supplementation with Artemisia extract may reduce HOMA-IR, but beneficial effects on other markers such as FBG requires further investigations.

Correlation between gastrointestinal symptoms and adherence to traditional Persian medicine dietary recommendations in patients with vitiligo; a cross-sectional study.

OBJECTIVES: Vitiligo is a chronic disease associated with the depigmentation of regions of the skin secondary to structural or functional damage to melanocytes. This damage results from interactions between the immune system and oxidative stress. In traditional Persian medicine (TPM), the concept of 'Barass' or 'Pissi' encompasses a group of skin diseases including vitiligo, for which there has been an emphasis on the preventive and therapeutic role of dietary modifications. METHODS: In this cross-sectional study, 200 vitiligo patients and 200 controls were enrolled with a random sampling method. The participants included patients with vitiligo referred to the Dermatology Clinic of Shahid Faghihi Hospital (Shiraz, Iran), with the control group being comprised individuals who referred to this clinic for cosmetic purposes. Questionnaires comparing the severity of gastrointestinal symptoms and the rate of adherence to TPM dietary recommendations were filled by all participants. Data were analyzed using SPSS version 24.0. RESULTS: The case group was significantly less adherent to TPM recommendations than the control group (8.25 ± 27.16 vs. 31.8 ± 10.47; p<0.001). However, there was no significant difference between both groups in the Gastrointestinal Symptom Rating Scale (GSRS) scores (14.09 ± 14.84 vs. 12.62 ± 11.71; p = 0.105). In the case group, the level of adherence to the recommendations of TPM was significantly lower among patients with lower education levels (R=-0.194; p=0.017). Furthermore, there was a significant negative relationship between the length of the disease and adherence to TPM dietary recommendations (R=-0.247; p=0.002). CONCLUSIONS: In this study, the level of adherence to TPM recommendations was significantly lower among patients with vitiligo than the control group. Hence, further studies are suggested to identify the probable role of dietary habits in the pathogenesis of vitiligo.
