  Regioselective Synthesis of Water-Soluble Monophosphate Derivatives of Combretastatin A-1

  摘要：

  The natural products combretastatin A-4 (CA4) and combretastatin A-1 (CA1) are potent cancer vascular disrupting agents and inhibitors of tubulin assembly (IC50 = 1-2 mu M). The phosphorylated prodrugs CA4P and CA1P are undergoing human clinical trials against cancer. CA1 is unique due to its incorporation of a vicinal phenol, which has afforded the opportunity to prepare both diphosphate and regioisomeric monophosphate derivatives. Here, we describe the first synthetic routes suitable for the regiospecific preparation of the CA1-monophosphates CA1MPA (8a/b) and CA1MPB (4a/b). The essential regio chemistry necessary to distinguish between the two vicinal phenolic groups was accomplished with a tosyl protecting group strategy. Each of the four monophosphate analogues (including Z and E isomers) demonstrated in vitro cytotoxicity against selected human cancer cell lines comparable to their corresponding diphosphate congeners. Furthermore, Z-CA1MPA (8a) and Z-CA1MPB (4a) were inactive as inhibitors of tubulin assembly (Ic(50) > 40 mu M), as anticipated in this pure protein assay.

  Synthetic routes have been established for the preparation of regio- and stereoisomerically pure samples of the mono-beta-D-glucuronic acid derivatives of combretastatin A-1, referred to as CA1G1 (5a) and CA1G2 (6a). Judicious choice of protecting groups for the catechol ring was required for the regiospecific introduction of the glucuronic acid moiety. The tosyl group proved advantageous in this regard. The two monoglucuronic acid analogues demonstrate low cytotoxicity (compared to CA1, 2) against selected human cancer cell lines, with CA1G1 being slightly more potent than CA1G2.
