Taipan Natriuretic Peptides Are Potent and Selective Agonists for the Natriuretic Peptide Receptor A.

Cardiovascular ailments are a major cause of mortality where over 1.3 billion people suffer from hypertension leading to heart-disease related deaths. Snake venoms possess a broad repertoire of natriuretic peptides with therapeutic potential for treating hypertension, congestive heart failure, and related cardiovascular disease.

Precision-engineered Peptide and Protein Analogs: Establishing a New Discovery Platform for Potent GPCR Modulators.

Numerous members of the human G protein-coupled receptor (GPCR) superfamily are receptors of therapeutic interest. GPCRs are considered to be highly tractable for drug discovery, representing the targets of approximately one-third of currently licensed drugs. These successful drug discovery outcomes cover only a relatively small subset of the superfamily, however, and many other attractive receptors have proven to present significant challenges.

Atypical alpha-conotoxin LtIA from Conus litteratus targets a novel microsite of the alpha3beta2 nicotinic receptor.

Different nicotinic acetylcholine receptor (nAChR) subtypes are implicated in learning, pain sensation, and disease states, including Parkinson disease and nicotine addiction. alpha-Conotoxins are among the most selective nAChR ligands. Mechanistic insights into the structure, function, and receptor interaction of alpha-conotoxins may serve as a platform for development of new therapies.
