acid. All compounds prepared were evaluated for their ability to inhibit leukemia L1210 cell proliferation. Methyl 4-(isothiocyanatomethyl)thiazole-2-carbamate (7) was the most active compound in this screen, inhibiting the growth of L1210 leukemic cells with an IC50 = 3.2 microM. Mitotic blocking appears to be its primary mechanism of cytotoxic activity. Compound 7 also was the only compound which demonstrated

氨基甲酸甲酯(7)是该筛选中活性最高的化合物,其IC50 = 3.2 microM抑制了L1210白血病细胞的生长。有丝分裂阻断似乎是其细胞毒性活性的主要机制。化合物7也是唯一对实验感染的寄生虫表现出显着的体内抗丝虫活性的化合物。该化合物以100 mg / kg x 5天的剂量对彭氏布鲁氏菌无活性。
