Design, synthesis and fungicidal activity evaluation of novel pyrimidinamine derivatives containing phenyl-thiazole/oxazole moiety.

Diflumetorim is a member of pyrimidinamine fungicides that possess excellent antifungal activities. Nevertheless, as reported that the activity of diflumetorim to corn rust (Puccinia sorghi) was not ideal (EC = 53.26 mg/L).

Organoantimony(III) halide complexes with azastibocine framework as potential antitumor agents: Correlation between cytotoxic activity and N→Sb inter-coordination.

The relationship between chemical structure and in vitro cytotoxic activities of a series of azastibocine-framework organoantimony(III) halide complexes against cancerous (HepG2, MDA-MB-231, MCF-7 and HeLa) and nonmalignant (HEK-293) cell lines was studied for the first time. A positive correlation between cytotoxic activity and the length of N→Sb coordinate bond on azastibocine framework of same nitrogen substituent was observed. By comparison, the organoantimony(III) complex 6-cyclohexyl-12-fluoro-5,6,7,12-tetrahydrodibenzo[c,f][1,5]azastibocine (C4) exhibited the highest selectivity index, giving a IC(nonmalignant)/IC(cancerous) ratio of up to 8.
