Research Overview
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.
Mambalgin-1
Pre-clinical work shows mambalgin-1 can reduce pain behaviors by modulating proton-gated ion channels in peripheral and central pathways. It has become an important template for developing ASIC-targeted analgesics.
