  β-Glucuronyl carbamate based pro-moieties designed for prodrugs in ADEPT

  摘要：

  A number of pro-moieties 8a - e designed for prodrug preparation have been synthesized (chart 2). The pro-moieties, containing a glucuronyl carbamate group linked to a spacer possessing a terminal carboxylic acid group, have been synthesized from isocyanates 6 and anomerically unprotected glucuronic acids 10 (chart 2). The requisite isocyanates had to be prepared using the Curtius rearrangement. Glucuronyl carbamates proved to be excellent substrates for human beta-glucuronidase. The pro-moieties 8a - e can be coupled to hydroxy- or amino group containing drugs. The resulting prodrugs are designed to be activated by beta-glucuronidase (chart 1) and to be used in ADEPT. Application is demonstrated with the synthesis of daunomycin prodrugs 12a - e (chart 3).

  摘要：

  1-β-O-Glycopyranosyl carbamates 是通过在几乎 100% β-对映选择性下，从无保护的α-糖苷和异氰酸酯制备的。异氰酸酯则是由羧酸通过酰基叠氮化物原位制备得来的。

  The syntheses of prodrugs of paclitaxel, which can be used in ADEPT in order to target paclitaxel towards tumor cells, are described. The prodrugs 1 and 2a,b consist of a spacer molecule connected via a carbamate linkage to a beta-glucuronic acid. The spacer molecule is also connected via an ester linkage to the 2'-OH of paclitaxel. Enzyme-catalyzed hydrolysis of the glucuronic acid moiety by human beta-glucuronidase results in the liberation of the parent drug paclitaxel via gamma or delta lactam formation with half-lives of 45 min and 2h (1 and 2h). The prodrugs 1 and 2b are two orders of magnitude less cytotoxic than paclitaxel. (C) 1997, Elsevier Science Ltd.
