Abstract:
The global rise in antibiotic resistance and the emergence of infectious diseases have intensified the need for novel antimicrobial therapies. As a result, there is a growing demand to validate the ethnomedicinal claims that plant extracts possess antibacterial properties. This validation requires the characterization of specific phytoconstituents, including anti-infective compounds and antimicrobial peptides. This study explores the progress made in identifying and producing anti-infectives derived from plants, with a focus on their mechanisms of action, current applications, and future potentials. One key area of investigation is the therapeutic potential of phyto-molecules, that target bacterial cell membranes. These molecules which include phenols, alkaloids, terpenoids, saponins, and peptides, have shown significant ability to disrupt bacterial cell membranes through various molecular mechanisms. By impairing membrane integrity, inhibiting efflux pumps, and altering membrane permeability, phyto-molecules offer a novel strategy for combating drug-resistant bacterial strains. This disruption not only enhances the efficacy of conventional antibiotics but also provides standalone antimicrobial activity. In conclusion, phyto-molecules represent a promising solution to overcoming antibiotic resistance, with their ability to target structural and functional components of bacterial membranes offering new pathways for therapeutic development. However, further research is needed to assess the comparative effectiveness and safety of these plant-based molecules in relation to traditional membrane-disrupting antibiotics.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
