Description: | CAN508 is a potent, ATP-competitive CDK9/cyclin T1 inhibitor with an IC50 of 0.35 μM. CAN508 exhibits a 38-fold selectivity for CDK9/cyclin T over other CDK/cyclin complexes. Antitumor activity[1][2]. |
Target: | CDK9/cyclinT1:0.35 μM (IC50) CDK2/cyclinE:20 μM (IC50) cdk2/cyclin A:69 μM (IC50) Cdk4/cyclin D1:13.5 μM (IC50) CDK7/cyclin H:26 μM (IC50) Cdk1/cyclin B:44 μM (IC50) |
In Vivo: | CAN508 (60 mg/kg; i.p.; daily for 10 days) has antitumor effects in esophageal adenocarcinoma xenografts[1]. Animal Model: 4 weeks-old female nude mice (esophageal adenocarcinoma xenografts)[1] Dosage: 60 mg/kg Administration: I.p.; daily for 10 days Result: Caused reduction of tumor growth starting from post-treatment day three with 50.83% reduction. |
In Vitro: | CAN508 reduces the frequency of S-phase cells of the cancer cell line HT-29 in antiproliferation assays[1]. CAN508 (20-40 μM; 72 hours) significantly reduces cell proliferation in a dose dependent manner in all three esophageal adenocarcinoma cell lines (SKGT4, OE33 and FLO-1 cells) with IC50s ranging from 34.99 to 91.09 μM[2]. CAN508 (40 μM; 72 hours) increases apoptosis in all three esophageal adenocarcinoma cells[2]. Apoptosis Analysis[1] Cell Line: SKGT4, OE33 and FLO-1 cells Concentration: 40 μM Incubation Time: 72 hours Result: Increased apoptosis by 2 fold in all three esophageal adenocarcinoma cells compared to untreated controls. |
