Abstract
Medicinal plants are enriched with several active constituents responsible for their biopotency. Among these, peptides have received special attention due to their wide pharmacological profile including antimicrobial, anti-inflammatory, anti- AIDS, anti-malarial, cytotoxic, nematocidal, inhibitory activity against thrombin, trypsin, plasmin, tyrosinase and superoxide generation, calcium channel antagonistic activity and may prove better candidates to overcome the problem of resistance towards conventional drugs. Although linear peptides are associated with diverse bioactivities but cyclopolypeptides dominate over them due to the fact that inherent flexibility of linear peptides lead to different conformations which can bind to more than one receptor molecules, resulting in undesirable adverse effects. Furthermore, cyclization of peptides reduces the degree of freedom for each constituent within the ring and thus substantially leads to reduced flexibility, increased potency and selectivity of cyclic peptides. These cyclic congeners possess unusual or modified amino acid residues like dehydrohomoalanine (Dhha), (2S,3R)-3-hydroxy-3-methylproline as well as novel acid moieties such as 4-amino-3,5-dihydroxyhexanoic acid (Adha), (2S,3R,5R)-3-amino-2,5-dihydroxy-8-phenyloctanoic acid (Ahoa), 3-amino-4-hydroxy-6-methyl-8-phenylocta-5,7- dienoic caid (AHMP) and exhibit their bioactivities through binding to corresponding enzymes. This characteristic feature can allow bioactive cyclopeptides to act as therapeutic agents in this resistant world. Present report includes complex structures, synthesis by solution phase technique, biopotential of natural cyclopolypeptides of plant origin.
