Compound 1 (C21H28N3O5PS, Mr = 465.49) belongs to the orthorhombic system, space group P212121, with a = 10.83653(16), b = 12.04906(19), c = 18.0061(3) A, V= 2351.06(6) A3, Z= 4, Dc= 1.315 g/cm3, p = 2.177 mm-1, F(000) = 984.0, the final R = 0.0389 and wR = 0.0985 for all data. Compound 2 (C20H25BrN304PS, Mr = 514.37) belongs to the orthorhombic system, space group P212121, with a = 10.9187(5), b = 11.9522(4), c = 17.7667(7) A, V= 2318.60(16) A3, Z = 4, Dc= 1.474 g/cm3,μ = 4.175 mm^-1, F(000) = 1056.0, the final R = 0.0367 and wR = 0.0946 for all data.展开更多

Preliminary biological tests showed that complexes 1(CuL2Cl2(R=CH3)) and 5(ZnL2Cl2(R=n-C3H7)) exhibited a certain weeding activity against wheat and barnyard grass.展开更多

The in vitro cytotoxic activity of the novel compounds was tested against human esophageal carcinoma cells (EC109), human hepatocarcinoma cells (HepG2), human gastric carcinoma cells (MGC-803), respectively, by the MTT method. The evaluation results revealed that compounds fimb, 6mf, 6mg, 6rid and 6nh exerted the most potent inhibition against HepG2, MGC-803 and EC109 cells, respectively. In particular, compound 6rag presented excellent inhibitory effect against HepG2 (91.2%) and MGC-803 (94.4%) cells.展开更多
