  Requirements for large-scale synthesis of the potent antitumor drug 10-deazaminopterin have led to development of a facile synthesis of this compound and its 10-alkyl analogues. The lithium diisopropyl amide generated dianions of appropriate p-alkylbenzoic acids were alkylated with 3-methoxyallyl chloride.

  Five analogues of methotrextate (MTX), 10-deazaaminopterin (10-DAM), and 10-ethyl-10-deazaaminopterin (10-EDAM) in which the glutamate moiety was replaced by either a gamma-methyleneglutamate or beta-hydroxyglutamate were synthesized and evaluated for their antifolate activity. These analogous are 4-amino-4-deoxy-N-10-methylpteroyl-beta-hydroxyglutamic acid (1), 4-amino-4-deoxy-10-deazapteroyl-beta-hydroxyglutamic acid (2), 4-amino-4-deoxy-N-10-methylpteroyl-gamma-methyleneglutamic acid (3, MMTX), 4-amino-4-deoxy-10-deazapteroyl-gamma-methyleneglutamic acid (4, MDAM), and 4-amino-4-deoxy-10-ethyl-10-deazapteroyl-gamma-methyleneglutamic acid (5, MEDAM). None of these compounds were metabolized to the respective polyglutamate derivative as judged by their inability to serve as substrates for CCRF-CEM human leukemia cell folypolyglutamate synthetase (FPGS) in vitro. All compounds inhibited recombinant human-dihydrofolate reductase (DHFR) at nearly equivalent magnitude as MTX. Growth-inhibition studies with H35 hepatoma, Manca human lymphoma, and CCRF-CEM human leukemia cells established greater cytotoxic effects with compounds 3-5 than with compounds 1 and 2. Gamma-Methyleneglutamate derivatives 3-5 were transported to H35 hepatoma cells better than MTX or beta-hydroxyglutamate derivatives 1 and 2. Compound 3 was 2.5 times better than MTX in competing with folinic acid transport in H35 hepatoma cells. Compound 1 did not have a significant inhibitory effect on folinic acid transport even at 50-mu-M under identical conditions. The IC50 for compound 1 against H35-hepatoma cell growth was 8.5-fold higher than MTX. Compounds with the gamma-methyleneglutamate moiety (3-5) exhibited almost equal or lower IC50 values than MTX against the growth of CCRF-CEM human leukemia cells. These studies show that on continuous exposure, the non-poly glutamylatable inhibitors DHFR (3-5) can exhibit superior antifolate activity compared to the polyglutamylatable methotrexate, presumably due to their enhanced transport to these cell lines. Compounds 3-5 appear to be excellent models to study the role of polyglutamylation of antifolates in antitumor activity and host toxicity.

  Seven N-alpha-(4-amino-4-deoxypteroyl)-N-sigma-hemiphtha (2, PT523) analogues were synthesized by modifications of the literature synthesis of the corresponding AMT (1) analogues and were tested as inhibitors of tumor cell growth. in growth assays against cultured CCRF-CEM human leukemic cells exposed to drug for 72 h, the IC50 values of analogues in which N-10 was replaced by CH2 and CHMe were found to be 0.55 +/- 0.07 and 0.63 +/- 0.08 nM, and thus these analogues are more potent than 1 (IC50 = 4.4 +/- 1.0 nM) or 2 (IC50 = 1.5 +/-: 0.39 nM). The 10-ethyl-10-deaza analogue of 2 (IC50 = 1.2 +/- 0.25 nM) was not statistically different from 2 but was more potent than edatrexate, the 10-ethyl-10-deaza analogue of 1, which had an IC50 of 3.3 +/- 0.36 nM. In contrast, the analogue of 2 with both an ethyl and a CO2Me group at the 10-position had an IC50 of 54 +/- 4.9 nM, showing this modification to be unfavorable. The 4-amino-1-naphthoic acid analogue of 2 had an IC50 Of 1.2 +/- 0.22 nM, indicating that replacement of the p-aminobenzoic acid (pABA) moiety does not diminish cytotoxicity. The analogues in which the (CH2)(3) Side chain was replaced by slightly longer CH2SCH2 and (CH2)(2)-SCH2 groups gave IC50 values of 4.4 +/- 1.1 and 5.0 +/- 0.56 nM and thus were somewhat less potent than the parent molecule. However the analogues in which the aromatic COOH group was at the meta and para positions of the phthaloyl ring had IC50 values of 7.5 +/- 0.47 and 55 +/- 0.07 nM, confirming the low potency we had previously observed with these compounds against other cell lines. Overall, the results in this study support the conclusion that, while the position of the phthaloyl COOH group and the length of the amino acid side chain in 2 are important determinants of cytotoxic potency, changes in the pABA region and 9,10-bridge are well-tolerated and can even increase potency.
