OBJECTIVE: To contrast scientific facts with suggested manufacturers' claims regarding food supplements (natural products) marketed for enhanced athletic prowess. DATA SOURCES: A MEDLINE search was performed to obtain documentation supporting the claims of natural-product manufacturers. In addition, several references pertaining to pharmacognosy, natural products, herbs, pharmacy practice, and sports medicine were reviewed. Claims were obtained from promotional advertisements in bodybuilding magazines, product labels, and fact sheets for sales representatives in nutrition and health-food stores. DATA EXTRACTION: We reviewed all of the clinical trials, published between 1966 and 1992, relative to the manufacturers' claims regarding these products. DATA SYNTHESIS: Pertinent human and/or animal studies supporting each natural product were compared with the manufacturers' claims. CONCLUSIONS: We found that there was no published scientific evidence to support the promotional claims for a large proportion of the products (8/19,42 percent). Only 4 of 19 products (21 percent) were associated with any documented human clinical trials supporting their promotional claims. Six of 19 agents (32 percent) had some scientific documentation to support their promotional claims; however, these products were judged to be marketed in a misleading manner.

Tulsi, the famous "unmatched" plant of India, is one of the most popular and beneficial of the numerous therapeutic and health-promoting herbs. Ayurvedic and Unani systems Medicinal natural products are increasingly being investigated in clinical trials for superior pharmacological responses and lack of side effects compared to symptomatic agents. Ocimum sanctum, often referred to as "Holy Basil" or "Tulsi," is known in the traditional Ayurvedic literature for its use in the treatment of many illnesses. The active ingredients obtained from plants, and their biological function in disease prevention have stimulated people's curiosity. This overview includes the nomenclature of plant vesicles, their components, and their use in the treatment of diseases. KEYWORDS: Illness, Ayurveda, Diseases, Treat, Tulsi, Natural product, Plant

Abstract It is frequently assumed, particularly in the last 15 plus years, that “Natural Product Structures” are no longer a source of drugs in the twenty-first century. In fact, this is not at all true. Even today, in the search for novel agents against manifold diseases, natural product structures, some quite old and some quite recent, are behind the compounds that are either recently (last 5–10 years) approved or that are now in clinical trials against manifold diseases of man. This chapter will cover agents approved since 2010 to the end of 2017 by the US FDA and its equivalent in other countries, plus selected agents that have entered clinical trials against major diseases such as cancer and infections that have “in their chemical pedigree” a natural product structure, even if the final product may be totally synthetic in nature.

The lipoxazolidinone family of marine natural products, with an unusual 4-oxazolidinone heterocycle at their core, represents a new scaffold for antimicrobial discovery; however, questions regarding their mechanism of action and high lipophilicity have likely slowed follow-up studies. Herein, we report the first synthesis of lipoxazolidinone A, 15 structural analogs to explore its active pharmacophore, and initial resistance and mechanism of action studies. These results suggest that 4-oxazolidinones are valuable scaffolds for antimicrobial development and reveal simplified lead compounds for further optimization.

: Matrix metalloproteinases (MMPs) are a group of zinc-dependent metallo-endopeptidase that are responsible towards the degradation, repair and remodelling of extracellular matrix components. MMPs play an important role in maintaining a normal physiological function and preventing diseases such as cancer and cardiovascular diseases. Natural products derived from plants have been used as traditional medicine for centuries. Its active compounds, such as catechin, resveratrol and quercetin, are suggested to play an important role as MMPs inhibitors, thereby opening new insights into their applications in many fields, such as pharmaceutical, cosmetic and food industries. This review summarises the current knowledge on plant-derived natural products with MMP-modulating activities. Most of the reviewed plant-derived products exhibit an inhibitory activity on MMPs. Amongst MMPs, MMP-2 and MMP-9 are the most studied. The expression of MMPs is inhibited through respective signalling pathways, such as MAPK, NF-κB and PI3 kinase pathways, which contribute to the reduction in cancer cell behaviours, such as proliferation and migration. Most studies have employed in vitro models, but a limited number of animal studies and clinical trials have been conducted. Even though plant-derived products show promising results in modulating MMPs, more in vivo studies and clinical trials are needed to support their therapeutic applications in the future.
