摘要:
The synthesis and antitumor activity of (2R,3R)-2,3-dihydroxy- and -2,3-dialkoxy-1,4-diaminobutane platinum(II) complexes 10-15 are described. cis-Dichloro [(2R,3R)-2,3-dimethoxy-1,4-diaminobutane]platinum(II) (11) and cis-(cyclobutane-1,1-dicarboxylato) [(2R,3R)-2,3-dihydroxy-1,4-diaminobutane]platinum(II) (13) showed the potent antitumor activity against L1210 leukemia in mice with % T/C values of around 200.
描述了一系列[2-取代-4,5-双(氨基甲基)-1,3-二氧戊环]铂(II)配合物的合成,物理性质,抗肿瘤活性,结构活性关系和肾毒性。已制备了该系列中具有七元环结构的42种铂(II)配合物,并通过1 H NMR,13 C NMR,IR,FAB-MS和元素分析对其进行了表征。该系列的所有成员均设计成在其载体配体中具有1,3-二氧戊环环部分以增加水溶性。铂配合物的溶解度与在4,5-双(氨基甲基)-1,3-二氧戊环载体配体中剩余配体和2-取代基的性质有关。通常,在4,5-双(氨基甲基)-1,3-二氧戊环部分中具有两个不同的R 1和R 2取代基的化合物比具有相同取代基的化合物具有更高的水溶性。该系列的大多数成员对移植到小鼠中的小鼠L1210白血病细胞显示出优异的抗肿瘤活性,并且优于顺铂和卡铂。(4R,5R)-立体异构体1a-h在(1,1-环丁烷二羧基)铂(II)配合物中比相应的(4S,5S)-立体

The alpha,omega-diazidoalditol derivatives with erythro, threo, xylo, ribo, D-arabino, D-manno, and D-gluco configuration were efficiently synthesized, respectively, from bis- or tris-cyclic sulfite or peracetylated alpha,omega-dibromoalditol intermediates. The cyclic sulfite intermediates has the advantage to lead directly to the free alpha,omega-diazido-alpha,omega-dideoxyalditols.
