Preclinical evaluation of therapeutic effects of targeted cytotoxic analogs of somatostatin and bombesin on human gastric carcinomas

Abstract

Experimental human gastric carcinomas that expressed high-affinity subtype 1 bombesin receptors were inhibited by cytotoxic bombesin analog AN-215, and tumors with high concentrations of sst2 or sst5 somatostatin receptors were suppressed by cytotoxic somatostatin analog AN-238. These findings suggest that this class of targeted compounds should be considered for the therapy of patients with advanced gastric carcinoma.
