Bioactive Compounds and Their Derivatives: An Insight into Prospective Phytotherapeutic Approach against Alzheimer’s Disease. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:5100904.

Abstract
Alzheimer's disease (AD) is a common neurodegenerative brain disorder that causes cellular response alterations, such as impaired cholinergic mechanism, amyloid-beta (Aβ) AD aggregation, neuroinflammation, and several other pathways. AD is still the most prevalent form of dementia and affects many individuals across the globe. The exact cause of the disorder is obscure. There are yet no effective medications for halting, preventing, or curing AD's progress. Plenty of natural products are isolated from several sources and analyzed in preclinical and clinical settings for neuroprotective effects in preventing and treating AD. In addition, natural products and their derivatives have been promising in treating and preventing AD. Natural bioactive compounds play an active modulatory role in the pathological molecular mechanisms of AD development. This review focuses on natural products from plant sources and their derivatives that have demonstrated neuroprotective activities and maybe promising to treat and prevent AD. In addition, this article summarizes the literature pertaining to natural products as agents in the treatment of AD. Rapid metabolism, nonspecific targeting, low solubility, lack of BBB permeability, and limited bioavailability are shortcomings of most bioactive molecules in treating AD. We can use nanotechnology and nanocarriers based on different types of approaches.

Abstract
Alzheimer’s disease (AD) is the number one neurovegetative disease, but its treatment options are relatively few and ineffective. In efforts to discover new strategies for AD therapy, natural products have aroused interest in the research community and in the pharmaceutical industry for their neuroprotective activity, targeting different pathological mechanisms associated with AD. A wide variety of natural products from different origins have been evaluated preclinically and clinically for their neuroprotective mechanisms in preventing and attenuating the multifactorial pathologies of AD. This review mainly focuses on the possible neuroprotective mechanisms from natural products that may be beneficial in AD treatment and the natural product mixtures or extracts from different sources that have demonstrated neuroprotective activity in preclinical and/or clinical studies. It is believed that natural product mixtures or extracts containing multiple bioactive compounds that can work additively or synergistically to exhibit multiple neuroprotective mechanisms might be an effective approach in AD drug discovery.

Preparation of cerium-curcumin and cerium-quercetin complexes and their LEDs irradiation assisted anticancer effects on MDA-MB-231 and A375 cancer cell lines. Photodiagnosis Photodyn Ther 2021; 34:102326.

Abstract
Cancer remains common and often is difficult to eradicate. In particular resistant forms like triple negative breast cancer and melanoma generally allow for very short survival. Curcumin and quercetin as two important polyphenols from plants which have different biological roles, potentially including anti-cancer effect. But their clinical application is limited due to poor solubility in aqueous medium. Photodynamic therapy (PDT) is a cancer treatment using select chemical compounds as photosensitizers, which when activated by light create toxic singlet oxygen. Studies done on plant based photosensitizers such as curcumin and quercetin have shown the ability to ablate tumors. Here we discuss using them as improved PS by making their complex with cerium ions as a delivery system for MDA-MB-231 and A375 cancer cell lines treatment. For this purpose, the MDA-MB-231 human breast cancer cell line exposed to red light irradiation (as pretreatment) then treated with curcumin and quercetin alone and also their complex with cerium. In another study the cells treated with curcumin-cerium and quercetin-cerium complex and then irradiated with blue light (photodynamic treatment). Cell survival and apoptosis were determined using MTT and fluorescence microscopy. The result showed that curcumin and quercetin in complex with cerium ions have better toxic effect against both breast and melanoma cancer cells as compared to each compound alone. The finding revealed that curcumin and quercetin in cerium complex could be considered as a new approach in the photodynamic treatment of breast and melanoma cancer cells.

Abstract
Curcuma longa (C. longa) or turmeric is a plant with a long history of use in traditional medicine, especially for treating inflammatory conditions C. longa and its main constituent, curcumin (CUR), showed various pharmacological effects such as antioxidant and anti-microbial properties. The updated knowledge of anti-inflammatory, antioxidant, and immunomodulatory effects of C. longa and CUR is provided in this review article. Pharmacological effects of C. longa, and CUR, including anti-inflammatory, antioxidant, and immunomodulatory properties, were searched using various databases and appropriate keywords until September 2020. Various studies showed anti-inflammatory effects of C. longa and CUR, including decreased white blood cell, neutrophil, and eosinophil numbers, and its protective effects on serum levels of inflammatory mediators such as phospholipase A2 and total protein in different inflammatory disorders. The antioxidant effects of C. longa and CUR were also reported in several studies. The plant extracts and CUR decreased malondialdehyde and nitric oxide levels but increased thiol, superoxide dismutase, and catalase levels in oxidative stress conditions. Treatment with C. longa and CUR also improved immunoglobulin E (Ig)E, pro-inflammatory cytokine interleukin 4 (IL)-4, transforming growth factor-beta, IL-17, interferon-gamma levels, and type 1/type 2 helper cells (Th1)/(Th2) ratio in conditions with disturbance in the immune system. Therefore C. longa and CUR showed anti-inflammatory, antioxidant, and immunomodulatory effects, indicating a potential therapeutic effect of the plant and its constituent, CUR, for treating of inflammatory, oxidative, and immune dysregulation disorders.

Abstract
INTRODUCTION The chronic metabolic disorder diabetes mellitus is a fast-growing global problem with huge social, health, and economic consequences, having one of the highest morbidities and mortality rates. Prolonged use of many available medications can produce undesirable side effects. Thus, plants appear as an important source of bioactive resources for the discovery of new treatments for diabetes. AREAS COVERED In this sense, this systematic review focused on clinical trials involving plants of National List of Medicinal Plants of Interest to the Unified Health System (RENISUS) (or compounds) with antidiabetic properties. We analyzed indexed studies in PubMed following the reporting guidelines of PRISMA. EXPERT OPINION Of the 51 clinical trials found, Curcuma longa, Glycine max, Zingiber officinale, Punica granatum, Aloe vera, Momordica charantia are the species with the greatest amount of clinical trials and the attenuation of insulin resistance, decreased fasting blood glucose and glycosylated hemoglobin levels are some of the main mechanisms by which these plants exert hypoglycemic effects. Thus, we speculate that the Clinical Pharmacology should explore the field of plant-based compounds that will keep concentrating the attention of researchers, and therefore, we gathered studies in advanced stages that highlight the role of plants in the diabetes therapy.

Abstract
Brahmi or aindri is a popular herb in the vast and rich compendium of herbs of Ayurveda and is botanically identified as Bacopa monnieri Linn. (BM). It is extensively used in Ayurveda and other traditional systems of medicine in the management of neurological psychiatric disorders. BM possess active principles belonging to alkaloids, glycosides, flavonoids, saponins categories. Numerous research have been undertaken across the globe to evaluate the neuroprotective potential of this herb. This review collates and summarises current (as on May 2020) published literature on Brahmi as a neuroprotective in neurological and psychiatric disorders. English language articles from databases PubMed, Scopus and Google scholar were searched using appropriate free keywords and MeSH terms related to the topic. The review demonstrates the neuroprotective potential of the Ayurveda herb Brahmi in several disorders including Alzheimer's disease, epilepsy, Parkinson's disease, Huntington's disease, cerebral ischemia and infarct and neoplasms.
