Synthesis, evaluation of chemical reactivity, and murine antineoplastic activity of 2-hydroxy-5-(3,4-dichlorophenyl)-6,7-bis(hydroxymethyl)-2,3-dihydro-1H-pyrrolizine bis(2-propylcarbamate) and 2-acyloxy derivatives as potential water-soluble prodrugs

2-Hydroxy-5-(3,4-dichlorophenyl)-6,7-bis(hydroxymethyl)-2,3-dihydro-1H- pyrrolizine bis(2-propylcarbamate) (11) was prepared in a multistep synthesis. The 2-hydroxy group was used to prepare ester prodrugs 14 and 15, and the antineoplastic activities of 11, 14, and 15a were compared to 1 (the 2-deoxy analogue of 11) in murine P388 lymphocytic leukemia and B16 melanocarcinoma. The alcohol 11 showed
通过多步合成法制备2-羟基-5-(3,4-二氯苯基)-6,7-双(羟甲基)-2,3-二氢-1H-吡咯嗪双(2-丙基氨基甲酸酯)(11)。2-羟基用于制备酯前药14和15,并将11、14和15a的抗肿瘤活性与鼠P388淋巴细胞白血病和B16黑素瘤中的1(11的2-脱氧类似物)进行比较。醇11显示出与1相当的活性,而14显示出较低的活性,而15a显示出非常低的活性。比较了1、11、14、15a和15b的水解速率,发现这两个氨基甲酸酯部分比C-2酯更易于水解。盐15a和15b显示出良好的水溶性,分别为3.0×10(-2)和3.88×10(-2)M。
