  Studies on the antitumor effects of analogues of 5,8-dideazaisofolic acid and 5,8-dideazaisoaminopterin

  摘要：

  Six new analogues of 5,8-dideazaisofolic acid and 5,8-dideazaisoaminopterin were synthesized in an effort to obtain enhanced antitumor activity. The modifications included the replacement of the 2-amino group by hydrogen or methyl as well as the inclusion of a methyl substituent at position 9. Based upon activity against L1210 leukemia cells in culture, three of the new analogues together with one compound described previously were evaluated for cytotoxicity in vitro using three human tumor cell lines (Cole 320 DM, Hep G2 and HL-60). The most effective compound was 2-desamino-N-9-methyl-5,8-dideazaisoaminopterin (2c) with the HL-60 cells being the most sensitive to its cytotoxic effects. These analogues were evaluated in vitro as inhibitors of dihydrofolate reductase (DHFR) and thymidylate synthase (TS) from human as well as bacterial (Lactobacillus casei) sources. All four of the 4-amino analogues were most effective toward L. casei DHFR compared with human DHFR, with 2-desamino-2-methyl-5,8-dideazaisoaminopterin (2d) and its 9-methyl derivative (2e) having 818- and 430-fold greater selectivity (L. caseilhuman). Most of the compounds studied were found to be only modest inhibitors of human TS (I-50 values = 1.5 to 20 mu M) and were therefore at least 40-fold less inhibitory than 10-propargyl-5,8-dideazafolic acid. Nevertheless, reversal of cytotoxicity studies with thymidine, hypoxanthine and folinic acid using the HL-60 cell line suggested that TS is the primary target for these analogues.

• A new synthetic approach of N-(4-amino-2-methylquinolin-6-yl)-2-(4-ethylphenoxymethyl)benzamide (JTC-801) and its analogues and their pharmacological evaluation as nociceptin receptor (NOP) antagonists

  A series of 4-amino-2-methylquinoline and 4-aminoquinazoline derivatives, including the reference NOP antagonist JTC-801, were synthesized by an alternative pathway and their in vitro pharmacological properties were investigated. 3-Substitution of the quinoline ring resulted very critical for affinity. So 3-methyl derivative 4j showed a similar potency compared with the reference 4h while bulky lipophilic or electron withdrawing groups in the same position strongly decreased affinity. Structural and conformational requirements for affinity were outlined by NOE NMR and computational methods and suggestions for a pharmacophore model design were provided. (C) 2004 Elsevier SAS.
