Natural bioactive thiazole-based peptides from marine resources: Structural and pharmacological aspects

Abstract

Peptides aredistinctivebiomacromolecules thatdemonstratepotential cytotoxicityanddiversified bioactivities against a variety of microorganisms including bacteria, mycobacteria, and fungi via their unique mechanisms of action. Among broad-ranging pharmacologically active peptides, natural marine-originated thiazole-based oligopeptides possess peculiar structural features along with a wide spectrum of exceptional and potent bioproperties. Because of their complex nature and size divergence, thiazole-based peptides (TBPs) bestow a pivotal chemical platform in drug discovery processes to generate competent scaffolds for regulating allosteric binding sites and peptide peptide interactions. The present study dissertates on the natural reservoirs and exclusive structural components of marine-originated TBPs, with a special focus on their most pertinent pharmacological profiles, whichmayimpart vital resources for the development of novel peptide-based therapeutic agents.
