Antitumor activity of 14 (dCDK9-202) in the TC-71 xenograft model in immunocompromised mice. (A) Changes in tumor volume during dCDK9-202, 6 (SNS032), or 10 (THAL-SNS032) treatments (10 mg/kg, i.v., qod). (B) Tumor weight at the end point of experiment. (C) Image of subcutaneous TC-71 xenograft tumors harvested at the end point of experiment. (D) Body weight of recipient mice during treatments. (E) Western blot analysis of CDK9 protein levels in tumor lysates harvested 4 h after final treatment (representative samples shown). Data in panels A, B, and D are presented as mean ± SD and were analyzed by one-way ANOVA (significance denoted as n.s., not significant; *, p < 0.05; **, p < 0.01; ***, p < 0.001).
