1-(3-(difluoromethyl)isothiazol-5-yl)-3-(2-fluoro-5-(hydroxymethyl)pyridin-4-yl)urea Chemical Properties,Usage,Production

Uses

BRM/BRG1 ATP Inhibitor-1 (compound 14) is an orally active allosteric dual brahma homolog (BRM)/SWI/SNF related matrix associated actin dependent regulator of chromatin subfamily A member 2 (SMARCA2) and brahma related gene 1 (BRG1)/SMARCA4 ATPase activity inhibitor, both IC50s are below 0.005 μM. BRM/BRG1 ATP Inhibitor-1 has anticancer activity[1].

Biological Activity

NVP-RXI570 is an orally active, potent, and selective allosteric dual inhibitor of BRM ((SMARCA2) and BRG1 (SMARCA4) th at th at downregulates BRM-dependent gene expression. NVP-RXI570 exhibits antiproliferative activity in a BRG1 mutant-lung-tumor xenograft model.

in vivo

BRM/BRG1 ATP Inhibitor-1 (compound 14) (oral administration, 7.5 or 20 mg/kg, everyday, 3 weeks) can inhibit tumor growth and inhibit KRT80 expression in a dose-dependent manner^[1].

Animal Model:	Female athymic nude mice with RERF-LC-AI tumor xenografts^[1]
Dosage:	7.5 mg/kg, 20 mg/kg
Administration:	Oral administration; everyday; 3 weeks
Result:	Inhibited tumor growth by 21% and 55% at doses of 7.5 mg/kg and 20 mg/kg, respectively. Inhibited KRT80 expression by up to 90% at 20 mg/kg for 7 hours after administration.
