Description
GM 1489 is a broad-spectrum inhibitor of matrix metalloproteinases (MMPs) with K
i values of 0.002, 0.1, 0.5, 0.2, and 20 μM for MMP-1, MMP-8, MMP-2, MMP-9, and MMP-3, respectively. It reduces 5-aza-2''-deoxycytidine-induced increases in MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, and MMP-14 expression as well as cell invasion in AsPC-1, BxPC-3, Hs766T, MiaPaCa2, and PANC-1 cancer cells. Topical administration of GM 1489 (100 μg) inhibits increases in ear thickness and epidermal hyperplasia induced by phorbol 12-myristate 13-acetate (TPA; ) and phorbol dibutyrate (PdiBu) in mice.
