Mechanism of CID 3117694 inhibition of ADAM10. (A) Plot of Kobs versus [I] for CID 3117694 inhibition of ADAM10. Please note the hyperbolic relationship between kobs and [I] suggesting that inhibitor binding complies with the two-step model. (B) Plot of Kobs versus [S]/KM for CID 3117694 inhibition of ADAM10. Please note kobs decreases with increase of [S]/KM suggesting that inhibitor competes with a substrate. (C) Dose response study of ADAM10 inhibition by AHA alone and in the presence of varying dose of CID 3117694. Please note that AHA IC50 decreases significantly in the presence of CID 3117694. (D) Normalized isobologram of two drug combination effect on ADAM10 activity. Please note that majority of AHA-CID 3117694 combinations produced synergistic effect as compared to a single drug application.
