以取代的苯乙酸、2-氨基硫脲为起始原料,经多步反应制备了一系列结构新颖的噻二唑类肽衍生物,其结构经1H NMR,13C NMR,HRMS确证.目标化合物应用3-(4,5-二甲基-2-噻唑基)-2,5-二苯基溴化四唑(MTT)法初步测试了抑制人白血病细胞(K562细胞)及前列腺癌细胞(PC-3细胞)增殖的活性,结果表明大部分目标化合物具有良好的抗肿瘤细胞增殖活性.针对5个活性目标化合物又进行了三株肿瘤细胞的深入活性评价,发现目标化合物(S)-(2-((1-((5-(1,1'-联苯-4-基甲基)-1,3,4-噻二唑-2-基)氨基)-1-氧亚基-3-苯基丙-2-基)氨基)-2-氧亚基乙基)氨基甲酸叔丁酯(6d)的活性最好,其抑制前列腺癌细胞(PC-3细胞)增殖的活性优于阳性药AT-101.

A series of thiadiazole peptidomimetic derivatives were prepared using different phenylacetic acids and thiosemicarbazide as the starting materials and followed by multi-step reactions. The structures of target compounds were identified by 1H NMR, 13C NMR and HRMS. The preliminary biological evaluations were performed on chronic myelogenous leukemia cell (K562 cell) and prostatic cancer cell (PC-3 cell) with 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The results suggested that most of target compounds have good antiproliferative activities against K562 cell. Further evaluations focused on the five active compounds using three tumor cell lines and found that (S)-tert-butyl(1-((2-((5-([1,1'-biphenyl]-4-ylmethyl)-1,3,4-thiadiazol-2-yl)amino)-2-oxoethyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (6d) exhibited better antiproliferative activities against prostatic cancer cell (PC-3 cell) compared with AT-101.

Key words: thiadiazole peptidomimetic, antitumor activity, prostatic cancer cell
