恶性肿瘤的化学疗法通常伴随着严重的副作用,因为常见的抗癌药物缺乏选择性。解决此问题的方法是抗体导向的酶前药疗法(ADEPT)和前药单一疗法(PMT)。在此,描述了适用于两个概念的新糖苷前药的合成和生物学评估。所有前药,但一个是人血清中稳定,并显示QIC 50个值(IC 50前药/ IC 50的前药在适当的糖水解酶的存在的)向上至6500。这是最好的值为止找到的与DNA相互作用的化合物。

The synthesis and biological evaluation of novel prodrugsbased on the cytotoxicantibioticduocarmycin SA (1) for a selective treatment of cancer using a prodrug monotherapy (PMT) are described. Transformation of the phenol 8 with the glucuronic acid benzyl ester trichloroacetimidate 9b followed by reaction with DMAI x HCl (10) gives the glucuronide 11b, which is deprotected to afford the desired
描述了基于细胞毒性抗生素双卡霉素SA(1)的新型前药的合成和生物学评估,该药物可使用前药单一疗法(PMT)选择性治疗癌症。用葡糖醛酸苄基酯三氯乙酰亚氨酸酯9b转化苯酚8,然后与DMAI x HCl(10)反应,得到葡糖醛酸苷11b,将其脱保护得到所需的含有葡糖醛酸酸部分的前药4a。另外,制备具有葡糖醛酸甲酯单元的前药4b。葡萄糖醛酸苷的细胞毒性使用HTCFA测定法确定,IC(50)值对于4a为610 nM,对于4b为3300 nM。在存在β-葡萄糖醛酸苷酶的情况下,4a表示的IC(50)值为0.9 nM,4b的表示为2.1 nM,导致QIC(50)的值对于4a约为700,对于4b约为1600。
