Research Overview
RgIA
Scientific studies show RgIA can strongly inhibit alpha9alpha10 nicotinic signaling with high selectivity compared with many other nAChR ligands. It is widely used to probe peripheral sensory pathways and inflammation-linked pain mechanisms.
ALRN-6924
ALRN-6924 is one of the best-known stapled peptide therapeutics and has advanced into human oncology studies. Literature shows that hydrocarbon stapling can improve target affinity, serum stability, and cellular activity for this p53-mimetic scaffold.
