Article	Year
Potential anticancer agents: 5-(N-substituted-aminocarbonyl)- and 5-(N-substituted-aminothiocarbonyl)-5,6,7,8-tetrahydrofolic acids. Journal of medicinal chemistry, 1988, Volume: 31, Issue:3 5-[[N-[(Ethoxycarbonyl)alkyl]amino]carbonyl] (6-9) and the corresponding aminothiocarbonyl (12-15) derivatives of 5,6,7,8-tetrahydrofolic acid were prepared as multisubstrate analogues of the substrate--cofactor adduct in the reactions catalyzed by the folate-mediated one-carbon transfer reactions. Evaluation in vitro showed that 7 (alkyl = hexyl) was cytotoxic to H.Ep.-2 cells (ED50, 4 microM) but noncytotoxic to proliferating L1210 cells. No activity was observed for 7 against the P388 leukemia in mice. Topics: Animals; Antineoplastic Agents; Leukemia L1210; Leukemia P388; Mice; Tetrahydrofolates	1988
Synthesis of pseudo cofactor analogues as potential inhibitors of the folate enzymes. Journal of medicinal chemistry, 1982, Volume: 25, Issue:2 Reaction of 5,6,7,8-tetrahydrofolic acid (THF,7) with phosgene, thiophosgene, and cyanogen bromide gave the bridged derivatives, 5,10-(CO)-THF (8), 5,10-(CS)-THF (9), and 5,10-(C = NH)-THF (11), respectively. Catalytic hydrogenation of 10-(chloroacetyl)folic acid (2) gave 5,10-(CH2CO)-THF (12). A similar reaction with 10-(3-chloropropionyl)folic acid (3) gave 10-(ClCH2CH2CO)-THF (14) rather than 5,10-(CH2CH2CO)-THF (13). In the catalytic hydrogenation of 10-ethoxalylfolic acid (5), the initial product 10-(EtO2CCO)-THF (22) rearranged readily to give 5-(EtO2CCO)-THF (21). Acylation of THF with chloroacetyl chloride gave a N5,N10-diacylated product (18 or 19), which could not be converted to 5,10-COCH2)-THF (17). Reductive alkylation of THF with glyoxylic acid and 5-hydroxypentanal, respectively, gave 5-(HO2CCH2)-THF (24) and 5-[HO(CH2)5]-THF (25). Reductive dialkylation of THF with formaldehyde gave 5,10-(CH3)2-THF (27), whereas glyoxal gave 5,10-CH2CH2)-THF (10). Also, both folic acid and 5-(CHO)-THF were reductively alkylated with formaldehyde to give 10-methylfolic acid (6) and 5-(CHO)-10-(CH3)-THF (28), respectively. These compounds were tested as inhibitors of the enzymes involved in folate metabolism and for activity against lymphocytic leukemia P388 in mice.
