NS13001

Description: NS13001 (N-(4-Chlorophenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)-9-methyl-9H-purin-6-amine) is a potent, selective, orally active allosteric positive modulator of SK channels (small conductance calcium-activated potassium channels). The EC50s are 1.8 and 0.14 µM for SK2 and SK3, respectively. NS13001 holds promise as a potential therapeutic agent for treatment of spinocerebellar ataxia type 2 (SCA2) and possibly other cerebellar ataxias. Target: Potassium Channel. Smiles: Cc1cc(C)n(n1)-c1nc(Nc2ccc(Cl)cc2)c2ncn(C)c2n1. References: Kasumu AW, et al.
