Gastric cancer represents a significant health burden worldwide. Previously, inspired by the traditional Chinese medicine Wu-Chu-Yu to treat the spleen and stomach system for thousands of years, we identified N14-phenyl substituted evodiamine derivatives as potential antitumor agents with favorable inhibition on Top1. Herein, structural optimization and structure-activity relationship studies (SARs) led us to discovering a highly active evodiamine derivative compound 6t against gastric cancer. Further anti-tumor mechanism studies revealed that compound 6t played as the inhibition of topoisomerase 1 (Top1), effectively induced apoptosis, obviously arrested the cell cycle at the G2/M phase, and significantly inhibited the migration and invasion of SGC-7901 and MGC-803 cell lines in a dose-dependent manner. Moreover, the compound 6t was low toxicity in vivo and exhibited excellent anti-tumor activity (TGI = 70.12%) in the MGC-803 xenograft models. In summary, compound 6t represents a promising candidate as a potential chemotherapeutic agent against gastric cancer.

Paragraph 0066-0068, (2021/07/17)
The invention particularly relates to a compound, a pharmaceutical composition, a medicine and application of the compound, the pharmaceutical composition and the medicine in preparation of antibacterial products. The seeking of a novel antibacterial target and the development of a novel chemical entity have important significance for solving the increasingly severe bacterial drug resistance problem at present, and the design of a compound entity acting on the FtsZ target is expected to be developed to obtain an antibacterial drug which has no influence on a host. The invention provides a 9-aralkyl-10-methylacridine quaternary ammonium salt derivative and a preparation method thereof, and the compound has significant bactericidal and/or bacteriostatic activity on gram-positive bacteria, has a good effect of inhibiting bacterial division protein FtsZ, and can be used for preparing antibacterial products.
