Crustacean Cardioactive Peptide, CCAP

SB290157 trifluoroacetate is a potent and selective antagonist of C3a receptor(IC50 of 200 nM). SB 290157 is a competitive antagonist of 125I-C3a radioligand binding to rat basophilic leukemia-2H3 cells expressing the human C3aR (RBL-C3aR, IC50 of 200 nM).

MSC 2032964A is a potent selective ASK1 inhibitor (IC50 = 93 nM) that is oral bioavailable and brain permeable. It inhibited neuroinflammation in mouse EAE models and blocked LPS-induced phosphorylation of ASK1 and p38 in cultured mouse astrocytes.
