In here, a series of coumarin-isoxazole derivatives were synthesized, characterized by spectroscopy technologies and evaluated for their cytotoxicity against HepG2 cell lines. Meanwhile, eight bioactive compounds were also evaluated for their toxicity on normal Vero cell lines. MC-16, a monoclinic crystal with P21/c space group, was further confirmed by X-ray and 2D-NMR. Results demonstrated that b5

生物活性结果表明八种化合物 (MC-2, MC-4, MC-5, MC-9, MC-10, MC-14, MC-19 and MC-20 )对HepG2
细胞系表现出弱到强的细胞毒性,对Vero细胞的毒性很大低于
