GI 254023X is a potent and selective inhibitor of the ADAM10 metalloprotease enzyme. It demonstrates significant activity against ADAM10 compared to ADAM17, with over 100-fold higher potency. In cell-based experiments, it effectively blocks the constitutive release of IL-6R, CX3CL1, and CXCL16, inhibits betacellulin shedding, prevents E-cadherin cleavage, and inhibits ADAM10-mediated neuronal outgrowth in vitro.
