[Polysuccinimide exhibited antitumor activity in the experiment].

Abstract

Antitumor activity of the novel for oncology compound, such as polysuccinimide, against some of experimental tumor models (Lewis lung carcinoma, Acatol adenocarcinoma, Ca-755 adenocarcinoma) has been established. This drug induced 60-80% tumor growth inhibition of these murine solid tumor strains. Polysuccinimide is also effective (60%) against development of metastatic process in lung (Lewis lung carcinoma). Polysuccinimide causes no changes in pH level in tumor tissue (P-388 leukemia, Acatol adenocarcinoma). This agent may be recommended for further profound preclinical study.
