Neuroinflammation: A Potential Risk for Dementia.

Dementia is a neurodegenerative condition that is considered a major factor contributing to cognitive decline that reduces independent function. Pathophysiological pathways are not well defined for neurodegenerative diseases such as dementia; however, published evidence has shown the role of numerous inflammatory processes in the brain contributing toward their pathology. Microglia of the central nervous system (CNS) are the principal components of the brain's immune defence system and can detect harmful or external pathogens. When stimulated, the cells trigger neuroinflammatory responses by releasing proinflammatory chemokines, cytokines, reactive oxygen species, and nitrogen species in order to preserve the cell's microenvironment. These proinflammatory markers include cytokines such as IL-1, IL-6, and TNFα chemokines such as CCR3 and CCL2 and CCR5. Microglial cells may produce a prolonged inflammatory response that, in some circumstances, is indicated in the promotion of neurodegenerative diseases. The present review is focused on the involvement of microglial cell activation throughout neurodegenerative conditions and the link between neuroinflammatory processes and dementia.

Guggulipid: A Promising Multi-Purpose Herbal Medicinal Agent.

Herbal medicines therapy is appreciated by many research works because herbal drugs have relatively high therapeutic window, lower side effects and more cost effective. Guggulipid is an ethyl acetate extract of resin known as guggul from the tree Commiphora wightii / mukul (Arn.) Bhandari. Chemical analysis revealed that the compounds responsible for the major activities of gum guggul are the isomers E- and Z-guggulsterone. Guggul has been used for thousands of years in the treatment of arthritis, inflammation, obesity, cardiac protection, anti-ulcer, anti-epileptic and disorders of lipid metabolism. This review is an assortment of available information reported on its chemical, pharmacological and toxicological properties in various research studies. The available therapeutic properties of guggulipid make it suitable natural product for the treatment of various disorders like inflammation, pain, wounds, liver disorder and Acne etc. Graphical Abstract Graphical Abstract.

A Phytochemical and Ethnopharmacological Recapitulation on Hamelia patens.

The world health organization reports that 80% of the population living within the developing countries depends basically on traditional medicine for his or her primary health care. Quite half the entire world's population still depends entirely on plants for medicines, and plants provides the active ingredients to the most traditional medical products. Hamelia patens that belong to the family Rubiaceae, is mainly found in tropical and sub-tropical areas. It is used in folk medicine against a wide range of diseases such as athlete's foot, skin problems, insect sting, psychiatric disorder, rheumatism, headache, asthma, dysentery, menses, ovarian and uterine disorders. Hamelia consists of an important bioactive constituent such as oxindole alkaloids, flavonoids, and phenolic content. Due to the presence of chlorogenic acid and epicatechin constituent in the methanolic extract of Hamelia patens, there is a noticeable anti-hyperglycemic activity as well as it possesses antioxidant activity. Acute and sub-acute toxicity study has been performed on Hamelia patens which shows that it is safe and can be used for humans. Against fungi and bacteria, the ethanol leaf extract of Hamelia has a maximum inhibitory effect. The plant has various therapeutic effects like anti-inflammatory, analgesic, anti-diarrheal, anthelmintic, antidepressant, hepatoprotective, antiurolithiatic, diuretic, wound healing, and many others. In this article, we have discussed chemical constituent, pharmacological activity and traditional use of Hamelia patens.

Current Pharmacological Trends on Myricetin.

Myricetin is a member of the group of flavonoids called flavonols. Myricetin is obtained from various fruit, vegetables, tea, berries and red wine. Myricetin is characterized by the pysrogallol B-ring, and the more hydroxylated structure is known to be capable for its increased biological properties compared with other flavonols. Myricetin is produced by the Myricaceae, Anacardiaceae, Polygonaceae, Pinaceae and Primulacea families. It is soluble in organic solvent such as ethanol, DMSO (dimethyl sulfoxide), and dimethyl formamide (DMF). It is sparingly soluble in aqueous buffers. Myricetin shows its various pharmacological activities including antioxidant, anti-amyloidogenic, antibacterial, antiviral, antidiabetic, anticancer, anti-inflammatory, anti-epileptic and anti-ulcer. This review article focuses on pharmacological effects of Myricetin on different diseases such as osteoporotic disorder, anti-inflammatory disorder, alzheimer's disease, anti-epileptic, cancer, cardiac disorder, diabetic metabolic disorder, hepatoprotective disorder and gastro protective disorder.
