  The Synthesis and Thymidylate Synthase Inhibitory Activity of L-.gamma.-L-Linked Dipeptide and L-.gamma.-Amide Analogs of 2-Desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583)

  摘要：

  Sixteen gamma-linked dipeptide and four L-Glu-gamma-amide analogues of 2-desamino-2-methyl-N-10-propargyl-5,8-dideazafolic acid (ICI 198583) have been synthesized and evaluated as inhibitors of thymidylate synthase (TS). Z-blocked L-Glu-gamma-L-linked dipeptides and L-Glu-gamma-amides were prepared by condensing alpha-tert-butyl-N-(benzyloxycarbonyl)-L-glutamic acid with the appropriate tert-butyl-protected L-amino acid or amine. The Z group was removed by catalytic hydrogenolysis, and the resulting dipeptides or L-Glu-gamma-amides were condensed with the appropriate pteroic acid analogue trifluoroacetate salt using diethyl cyanophosphoridate as coupling reagent. Deprotection with trifluoroacetic acid in the final step gave the desired quinazoline gamma-linked dipeptides and L-Glu-gamma-amides as their trifluoroacetate salts. Nearly all the dipeptide analogues were potent inhibitors of TS, the best being ICI 198583-gamma-L-2-aminoadipate (IC50 = 2 nM). Several of these dipeptides were found to be susceptible to enzymatic hydrolysis in mice. The quinazoline monocarboxylate L-Glu-gamma-amides, lacking an alpha'-carboxyl group, are less active against TS and L1210 cell growth but are also not susceptible to enzymatic hydrolysis in mice.

  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.

  the appropriate amino acid or amino acid ester. In cases where the amino acid ester was unreactive with the acid azide, a modification was used in which the quinazolinone moiety was protected as its 3-(pivaloyloxy)methyl derivative. This permitted the generation of the more reactive acid chloride of the p-aminobenzoate unit. In general these modifications result in compounds that have equivalent potency
