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.
Huwentoxin-IV
Studies show huwentoxin-IV can inhibit sodium-channel currents with notable selectivity, making it useful for dissecting pain-sensing neuron excitability. It is one of the better known spider-venom templates for Nav1.7-targeted drug discovery.
