Hazard Information

Description

MS177 is an effective and fast-acting EZH2 degrader. MS177 is a PROTAC that consists of a CRBN ligand, linker, and a potent enzymatic EZH2 inhibitor C24 (C24 IC50): 12?nM). MS177 effectively depletes both canonical EZH2–PRC2 and noncanonical EZH2–cMyc complexes. MS177 induces leukaemia cell growth inhibition, apoptosis and cell cycle progression arrest.

Uses

in vivo

MS177 (100?mg/kg, i.p., BID for 6 days) represses tumor growth in PDX animal model of MLL-r AML, and in subcutaneously xenografted MLL-r leukaemia models^[1].
MS177 (50 mg/kg, i.p.) achieves intraplasma concentrations about 1 μM in male Swiss Albino mice^[1].
MS177 (100?mg/kg, i.p., BID for 6?days per week; and 200?mg/?kg, i.p. BID 3?days per week) is well tolerated and lacks apparent toxicity in mice^[1].

Animal Model:	PDX animal model of MLL-r AML^[1]
Dosage:	100?mg/kg
Administration:	Intraperitoneal injection (i.p.), BID for 6 days.
Result:	Inhibited tumor growth and prolonged survival.
