  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.

• First use of the Taylor pteridine synthesis as a route to polyglutamate derivatives of antifolates

  The di- through penta-gamma-L-glutamates of 2-desamino-2-methylaminopterin, a new antifolate with a novel mechanism of action requiring gamma-polyglutamylation for biological activity, were prepared. alpha-tert-Butyl gamma-methyl L-glutamate was condensed with 4-nitrobenzoyl chloride, the methyl ester selectively hydrolyzed with base, and the product condensed with di-tert-butyl L-glutamate to obtain tri-tert-butyl N-(4-nitrobenzoyl)-gamma-L-glutamyl-L-glutamate. Reduction of the nitro group followed by reaction with 2-amino-5-(chloromethyl)-pyrazine-3-carbonitrile yielded tri-tert-butyl [4-[[(2-amino-3-cyanopyrazin-5-yl)methyl]amino]benzoyl]-L-gamma-glutamyl-L-glutamate, which was heated with acetamidine acetate to form tri-tert-butyl N-[4-[[(4-amino-2-methylpteridine-6-yl)methyl]amino]benzoyl]-gamma-L-glutamyl-L-glutamate. Removal of the ester groups with trifluoroacetic acid then gave 2-desamino-2-methylaminopterin diglutamate. A similar sequence was employed to convert esterified oligomers with three, four, and five glutamyl residues to 2-desamino-2-methylaminopterin tri-, tetra-, and pentaglutamate. This is the first example of the preparation of the polyglutamates of an antifolate via the Taylor pteridine synthesis.
