• 靶点： STAT3:86 μM (IC50);STAT

• 体内研究：
  Human breast (MDA-MB-231) tumor-bearing mice are given an i.v. injection of NSC 74859 (S3I-201) or vehicle every 2 or every 3 days for 2 weeks, and tumor measurements are taken every 2-3 days. Compared with control (vehicle-treated) tumors, which continued to grow, human breast tumors in mice that received S3I-201 display strong growth inhibition. Continued evaluation of treated mice on termination of treatment shows no resumption of tumor growth, suggesting potentially a long-lasting effect of S3I-201 on tumor growth. Compared with vehicle-treated control tumors (n=15), which continued to grow, S3I-201 treatment of somatotroph tumor xenografts (n=15) significantly attenuated tumor growth for the duration of the experiment. Tumors derived from NSC 74859-treated rats are significantly smaller than those from the untreated group (220±16 mm3 vs. 287±16 mm3, P<0.01) as early as 5 days after NSC 74859 injection. Fifteen days after treatments, the average tumor volume of NSC 74859-treated rats is 64% of that of controls (449±40 mm3 vs. 708±83 mm3, P<0.01). Rats are sacrificed and tumors are harvested 15 days after treatment initiation. The average tumor weight of NSC 74859-treated rats is 78±8 mg, while tumors derived from control rats weighed 114±13 mg (32% reduction; P<0.05).
