Product Overview
D-64131 is a tubulin polymerization inhibitor with an IC50 value of 0.53 μM. The polymerization of bovine brain tubulin as well as binding of [3H] colchicine to biotinylated αβ-tubulin was dose-dependently inhibited by D-64131. Many cancer cells display abnormal microtubule structures, such as fragmented mitotic spindles or multiple spindle poles after treatment with D-64131.Nuclear blebbing and abnormal nuclear structures typical for apoptotic cells are detectable in many cells treated with D-64131.In nude mice, D-64131 proved to be well tolerated and highly active against the human amelanoic melanoma MEXF 989 tumor xenograft. D-64131 treatment resulted in significant tumor growth inhibition during treatment.
