In experiments of mice and rats with transplantable tumors (sarcoma 37, sarcoma 45, ascites Ehrlich tumor, etc) the authors studied the antitumor activity of a number of new water-soluble derivatives of 2,4-diethylenimino-6-amino-sym.-triazine differing only in the substituting radical associated with sym.-triazine cycle. All substances under study showed marked antitumor activity. The effect of the structure of the compounds concerned and their physico-chemical properties for antitumor activity are discussed.

Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, notoriously refractory to conventional chemotherapy. Historically, sulfane sulfur-based compounds have been explored for the treatment of HCC, but their efficacy has been underwhelming. We recently reported a novel sulfane sulfur donor, PSCP, which exhibited improved chemical stability and structural malleability.

Ginkgolic acids (GAs) are distinctive secondary metabolites of () primarily found in its leaves and seeds, with the highest concentration located in the exotesta. GAs are classified as long-chain phenolic compounds, and exhibit structural similarities to lignoceric acid. Their structural diversity arises from variations in the length of side chains and their number of double bonds, resulting in six distinct forms within extracts (GBE).

Prostate cancer (PCa) is a highly common type of malignancy and affects millions of men in the world since it is easy to recur or emerge therapy resistance. Therefore, it is urgent to find novel treatments for PCa patients. In the current study, we found that tegaserod maleate (TM), an FDA-approved agent, inhibited proliferation, colony formation, migration as well as invasion, caused the arrest of the cell cycle, and promoted apoptosis of PCa cells in vitro.

Tumors are diseases caused by abnormal cell division and growth, which can be life-threatening if not treated properly. Serpin inhibitors play a crucial role in regulating pathophysiological process and are promising drug targets. Kallistatin (SERPINA4) and Pigment Epithelium-Derived Factor (PEDF, SERPINF1) are two serpins that lack protease inhibitory activity but are abundant in blood.

The aim of the present study was to obtain new metal complexes of citrus pectin with cobalt ions based on potassium polygalacturonate and to prepare a new pharmacological composition (PC) PGKCo: PGNaCo (1:1) with antitumor activity based on potassium cobalt polygalacturonate (PGKCo) and sodium cobalt polygalacturonate (PGNaCo). The study of the effect of PGKCo, PGNaCo and PC on the cell viability of tumor cell lines of different genesis in vitro showed that the obtained compounds are soluble in water and exhibit selective cytotoxic activity against the tumor cell lines of human lung carcinoma A549, breast adenocarcinoma MCF-7 and cervical carcinoma M-HeLa, with no significant toxic effect on normal human cells. The possible mechanism of action of the investigated PC on M-HeLa cancer cells was investigated.
