Diabetes mellitus is a chronic metabolic disorder marked by hyperglycemia, resistance to insulin, and impaired function of the pancreatic β-cells; it advances into more serious complications like nephropathy, neuropathy, cardiovascular disease, and retinopathy; herbal medicine has indicated promise in not just mitigating the symptoms but also in managing the complications. This review would aim to evaluate the pharmacological aspect of the botanical therapies Anacardium occidentale, Allium sativum, Urtica dioica, and Cinnamomum zeylanicum, as well as their bioactive phytochemicals, quercetin, resveratrol, berberine, and epigallocatechin gallate (EGCG). In this review, we discuss their mechanisms for secreting the insulin sensitizers, carbohydrate-hydrolyzing enzymes, reduction in oxidative stress and effectiveness against diabetic complications-all through sensitivity to insulin.

Article Synopsis
  • Helminthiasis is a major global health issue affecting billions, especially in poor areas with poor sanitation, and lacks an effective vaccine.
  • Current treatments, anthelmintics, target the parasites' neuromuscular functions, but rising resistance to drugs like benzimidazoles is a growing challenge.
  • This review explores the structure-activity relationships of various anthelmintic compounds developed since 2019, aiming to aid researchers in designing more effective treatments against helminth infections.

To combat resistance against current antimalarials, modifying key pharmacophores and exploring novel parasite-specific drug targets remained one of the key drug design strategies. The resistance to quinoline-based antimalarials arises often due to the efflux of the drug. Hence, the development of newer agents containing bulkier pharmacophores will enable medicinal chemists to counteract drug resistance.

Breast cancer is the most prevalent diagnosed cancer among women and the main cause of morbidity and mortality. As for breast cancer, MCF-7 cells are an important candidate since they are widely utilized in research for estrogen receptor (ER)-positive breast cancer cell assays, and various sub-clones have been identified to reflect different classes of ER-positive tumors with varied levels of nuclear receptor expression. Rhodamines and its derivatives have shown a great interest over the past two decades due to their excellent structural and spectroscopic properties.

Flavonoids are a diversified group of natural substances which were discovered to provide a variety of health benefits in human beings. Vegetables, fruits, wine and tea are the primary flavonoid dietary sources for humans and as the flavonoids are so closely connected to human dietary items and health, it is vital to explore the structural-activity connection. The arrangement, replacement of functional groups, and total number of hydroxyl groups around flavonoid's nucleus structure affect their biological activity, metabolism, and bioavailability.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease that causes dementia by impairing mental capacity growth and disrupting neurocognitive activity. Despite recent advancements in AD therapy, therapeutic effectiveness has been small, noncurative, and susceptible to drug resistance. The reality that AD's origin remains unknown and that the blood-brain barrier limits treatment effectiveness are two significant impediments to science.

Atherogenic dyslipidemia is a condition and responsible for the induction of major cardiovascular diseases. Traditionally, Nepeta hindostana a medicinal plant commonly used as cardioprotective in Indo-Pak regions has gained importance because of its therapeutic active flavonoid Nepitrin-7-O-glucoside. Flavonoid-glycosides are steroids having the ability to exert specific, decisive action on the cardiac muscle.

Background: Pyrethroids have prominently known for their insecticidal actions worldwide, but recent reports as anticancer and antiviral applications gained a lot of interest to further understand their safety and immunotoxicity.

Objective: This encouraged us to carry out our present study to evaluate the interactions of pyrethroids toward adaptive immune cell receptors.

Materials And Methods: Type 1 and Type 2 pyrethroids were tested on T (CD4 and CD8) and B (CD28 and CD45) immune cell receptors using Maestro 9.
