  β-Glucuronidase-Cleavable Prodrugs of O⁶-Benzylguanine and O⁶-Benzyl-2‘-deoxyguanosine

  摘要：

  Glucuronic acid linked prodrugs of O-6-benzylguanine and O-6-benzyl-2'-deoxyguanosine were synthesized. The prodrugs were found to be quite stable at physiological pH and were more than 200-fold less active as inactivators of O-6-alkylguanine-DNA alkyltransferase (alkyltransferase) than either O-6-benzylguanine or O-6-benzyl-2'-deoxyguanosine. beta-Glucuronidase from both Escherichia coli and bovine liver cleaved the prodrugs efficiently to release O-6-benzylguanine and O-6-benzyl-2'-deoxyguanosine, respectively. In combination with 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), the prodrugs were not effective adjuvants for HT29 cell killing. However, as expected, incubation of these prodrugs with beta-glucuronidase in the culture medium led to much more efficient cell killing by BCNU as a result of the liberation of the more potent inactivators, O-6-benzylguanine and O-6-benzyl-2'-deoxyguanosine. These prodrugs may be useful for prodrug monotherapy of necrotic tumors that liberate beta-glucuronidase or for antibody-directed enzyme prodrug therapy with antibodies that can deliver beta-glucuronidase to target tumor cells.

  Disclosed are prodrugs of inactivators of 06-alkylguanine-DNA alkyltransferase (AGT). The prodrugs are cleavable by the (3-glucuronidase enzyme, which is either administered to the patient or produced by necrotic tumor cells. The prodrugs are represented by the formula A-B-C, wherein A is a glucuronosyl residue linked through its 1-oxygen to the phenyl ring of B; B is a benzyloxycarbonyl group, optionally ring­ substituted with one or more electron withdrawing groups; and C is an inactivator of AGT, e.g., a substituted or unsubstituted 06-benzylguanine or 06-benzyl-2'-deoxyguanosine. Also disclosed are pharmaceutical compositions comprising a prodrug and a pharmaceutically acceptable carrier, and a method of use of the prodrugs in enhancing the chemotherapeutic treatment of tumor cells in a mammal, e.g., a human, with an antineoplastic alkylating agent that causes cytotoxic lesions at the 06-position of guanine.

  本发明公开了06-烷基鸟嘌呤-DNA烷基转移酶（AGT）失活剂的前药。这些前药可以被（3-葡萄糖醛酸酶酶）水解，该酶可以被注射到患者体内或由坏死肿瘤细胞产生。前药由公式A-B-C表示，其中A是通过其1-氧原子与B的苯环连接的葡萄糖醛酸残基；B是苄氧羰基基团，可以选择性地被一个或多个电子提取基团取代；而C是AGT的失活剂，例如取代或未取代的06-苄基鸟嘌呤或06-苄基-2'-脱氧鸟苷。本发明还公开了包含前药和药学上可接受的载体的制药组合物，以及在增强哺乳动物（例如人类）中肿瘤细胞的化疗治疗中使用前药的方法，该方法使用一种抗肿瘤烷基化剂，在鸟嘌呤的06位引起细胞毒性损伤。
