Phosphinic acid-based MMP-13 inhibitors that spare MMP-1 and MMP-3
摘要:
Phosphinic acid-based inhibitors of MMP-13 have been investigated with the aim of identifying potent inhibitors with high selectivity versus MMP-1. Independent variation of the substituents on a P-1' phenethyl group and a P-2 benzyl group improved potencies in both cases around 3-fold over the unsubstituted parent. Combining improved P-1' and P-2 groups into a single molecule gave an inhibitor with a 4.5 nM IC50 against MMP-13 and which is 270-fold selective over MMP-1. (C) 2003 Elsevier Science Ltd.

challenging deoxygenation of alkoxyl radicals from readily accessible alcohol derivatives was developed, affording facile synthesis of functionalized alkenes with good functional group tolerance under mild reaction conditions. Because alkoxyl radicals can easily undergo β‐fragmentations or hydrogen abstractions, this new strategy for deoxygenation of alkoxyl radicals is highly valuable. Moreover, mechanistic
