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.

SNX-482

SNX-482 has been used to dissect R-type calcium currents in neurons and endocrine cells, and to map the role of Cav2.3 in excitability. Its selectivity profile has made it a standard research reagent in channel pharmacology.
