Article Abstract
Natural products are an invaluable source for the discovery of drug and pesticide candidates. Piperine, a simple and pungent alkaloid, is isolated from several plants of Piperaceae. Piperine and its derivatives displayed a wide range of biological properties, such as antitumor activity, anti-inflammatory activity, antioxidant activity, neuroprotective activity, insecticidal activity, etc. In recent years, lots of works focused on the biological activities, mechanisms of action, total synthesis, and structural modifications of piperine and its derivatives have been conducted. To the best of our knowledge, however, few review articles related to the biological activities, mechanisms of action, total synthesis, and structural modifications of piperine and its derivatives have been reported to date. Therefore, this review summarizes the research advances (from 2014 to 2020) of piperine and its derivatives regarding bioactivity, mechanisms of action, total synthesis, and structural modifications. Meanwhile, the structure-activity relationships of piperine and its derivatives are also discussed.

Commercial herbal compounds are a main attractive target to explore for a novel drug for the treatment of HSV. This study investigated the anti-HSV infectivity of extracts derived from the Thai commercial herbals Kerra, KS, and Minoza. Wild-type HSV-1 KOS, HSV-2, and drug-resistant HSV-1 dxpIII were used to investigate any inhibitory effects of these extracts.

Background: As a biologically intricate process, aging entails functional impairment and predisposes individuals to chronic conditions. Medicine-food homology (MFH) plants, deeply rooted in traditional Chinese medicine, are increasingly recognized for their potential to delay aging through natural bioactive compounds.
Study Design: We conducted a comprehensive review of 56 MFH plants with documented anti-aging effects, focusing on 83 identified bioactive compounds grouped into 14 chemical categories, including phenols, polysaccharides, glycosides, and proteins.

Objectives: Alzheimer's disease (AD) is a neurological disorder that causes symptoms such as cognitive impairment and memory loss. The number of AD patients keeps escalating throughout the world leading to various social problems, meanwhile no practical treatment for the disease has been proposed. Some of the well-known causes of AD are excessive amyloid-β (Aβ) accumulation and tau hyperphosphorylation.

Malignant gliomas, including glioblastoma multiforme (GBM), are highly aggressive brain tumors with a poor prognosis and limited treatment options. This study investigates the antitumor potential of bioactive compounds derived from and using molecular docking, cell viability assays, and transcriptomic and expression analyses from public databases in humans and cell lines. Cannabichromene (CBC), cannabigerol (CBG), cannabidiol (CBD), and Piper nigrum derivates exhibited strong binding affinities relative to glioblastoma-associated targets GPR55 and PINK1.
