sb-203580

Adezmapimod (SB 203580) is a selective, ATP-competitive p38 MAPK inhibitor (IC50=0.3-0.5 μM) that activates autophagy and mitochondrial autophagy, with more than 100-fold higher selectivity over PKB, LCK, and GSK-3β.

SB 203580 hydrochloride (Adezmapimod hydrochloride) is a selective, ATP-competitive p38 MAPK inhibitor that induces mitochondrial autophagy and cytosolic autophagy and inhibits SAPK2a/p38, SAPK2b/p38β2, LCK, GSK3β, and PKBα. SB 203580 hydrochloride has been shown to be useful in antiretroviral therapy. 203580 hydrochloride inhibits amphoteric mechanical anomalous pain in a mouse model of antiretroviral-induced neuropathic pain.

SB 203580 sulfone, an analog of the p38 MAP kinase inhibitor SB 203580, inhibits IL-1 production in monocytes and binds competitively with CSAID binding proteins (CSBP), inhibiting stress response signaling. It exhibits an IC50 of 0.2 μM for IL-1 inhibition and 0.03 μM for CSBP-mediated signaling inhibition [1].

Tie2 kinase inhibitor 1 (Tie2 kinase inhibitor), an optimized compound of SB-203580, is selective to Tie2 with IC50 of 0.25 μM, which is 200-fold more effective than p38.
