  名称：

  Syntheses and thymidylate synthase inhibitory activity of the poly-.gamma.-glutamyl conjugates of N-[5-[N-(3,4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino]-2-thenoyl]-L-glutamic acid (ICI D1694) and other quinazoline antifolates

  摘要：

  Thirteen poly-gamma-glutamates derived from several novel antifolates have been synthesized by a convergent route. The syntheses of poly-gamma-glutamyl conjugates of N-[5-[N-(3,4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino]-2-thenoyl]-L-glutamic acid (8) (ICI D1694), 2-desamino-N10-propargyl-5,8-dideazafolic acid (6), 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (7), 2-desamino-2-methyl-N10-propargyl-2'-fluoro-5,8-dideazafolic acid (9), and 2-desamino-2-methyl-4-chloro-N10-propargyl-2'-fluoro-3,5,8-trideazafolic acid (11) are described. A key step in the route involves coupling of an alpha-tert-butyl-protected poly-gamma-glutamate of the required chain length to the appropriate 5,8-dideazapteroic acid, obtained by carboxypeptidase G2 cleavage of the parent monoglutamate, if available, or by chemical synthesis. Deprotection with trifluoroacetic acid in the final step gave the desired poly-gamma-glutamyl antifolates as their trifluoroacetate salts. As inhibitors of thymidylate synthase, these polyglutamates were more potent in every case than the corresponding non-polyglutamylated drug.
