Description

General description

A cell-permeable inhibitor of calpain I (K_i = 120 nM), calpain II (K_i = 230 nM), cathepsin B (K_i = 100 nM), and cathepsin L (K_i = 0.6 nM). Inhibits activation-induced programmed cell death and restores defective immune responses in HIV⁺ donors. Also prevents nitric oxide produced by activated macrophages by interfering with transcription of the inducible nitric oxide synthase gene.

Cell permeable inhibitor of calpain I (K_i = 120 nM), calpain II (K_i = 230 nM), cathepsin B (K_i = 100 nM), and cathepsin L (K_i = 600 pM). Inhibits activation-induced programmed cell death and restores defective immune responses in HIV⁺ donors. Blocks nitric oxide production by activated macrophages by interfering with transcription of the inducible nitric oxide synthase gene. A weak inhibitor of proteasome.
