Research Overview

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.

Kahalalide F

Kahalalide F was investigated in multiple preclinical and early clinical cancer studies because of its unusual membrane-disrupting and anti-tumor effects. Development highlighted the promise and limits of marine depsipeptides as oncology leads.
