(1S,2R) -Alicapistat

(1S,2R) -Alicapistat ((1S,2R) -ABT-957) is a highly efficient, orally active compound that selectively inhibits human calpains 1 and 2, showing promise for Alzheimer's disease (AD) therapy [1]. It effectively addresses the metabolic liability associated with carbonyl reduction and demonstrates potent inhibition of calpain 1 with an IC50 value of 395 nM [2].
