  Syntheses and bioevaluation of substituted dihydropyridines for pregnancy-interceptive activity in hamsters

  摘要：

  A number of 2,6-dimethyl-3,5-bis(methoxycarbonyl)-4-substituted-1,4- dihydropyridines were synthesized and evaluated for pregnancy-interceptive activity in mated hamsters. Out of 24 compounds, 12, 15, 21, 22, 28, and 34 caused a marked reduction in the number of implantations when administered on days 3-8 postcoitum. In an in vitro competition assay, none of the compounds exhibited noticeable binding affinity for uterine progesterone receptors. The results reported here have helped to identify new leads for developing pregnancy-interceptive agents and the active compounds do not seem to elicit their interceptive effect through receptor-mediated inhibition of progesterone action in hamster uterus.

  Derivatives of 4-substituted phenyl 1,4-dihydropyridine 3,5-dicarboxylic acids substituted by lower alkyl groups in the 2- and 6-positions, are cardiovascular agents. The compounds, of which 2,6-dimethyl-4-[2-(diethylaminoethoxy)-phenyl]-1,4-dihydropyridine-3,5-dic arboxylic acid 3,5-diethyl ester is a typical example, can be prepared through condensation of a .beta.-dicarbonyl compound with an amine and an aldehyde, of an ylidene-.beta.-ketocarboxylic acid ester, with a .beta.-ketocarbonyl compound and an amine, of an aldehyde, an enamine and a .beta.-ketocarbonyl compound, or through elaboration of the substituent on the phenyl group.

  lost; these compounds also inactivated cytochrome P-450 and caused the loss of nifedipine oxidase activity after enzymatic oxidation. All of these reactions were extensively inhibited by an antibody raised to purified human liver nifedipine oxidase cytochrome P-450 (P-450NF), indicating a major role for this enzyme in the oxidation of these compounds.

  A series of 21 different 4-substituted 2,6-dimethyl-3-(alkoxycarbonyl)-1,4-dihydropyridines was considered with regard to oxidation to pyridine derivatives by human liver microsomal cytochrome P-450 (P-450). Antibodies raised against P-450 IIIA4 inhibited the microsomal oxidation of nifedipine and felodipine to the same extent, as did cimetidine and the mechanism-based inactivator gestodene. Gestodene was approximately 10(3) times more effective an inhibitor than cimetidine, on a molar basis. When rates of oxidation of the 1,4-dihydropyridines were compared to each other in different human liver microsomal preparations, all were highly correlated with each other with the exceptions of a derivative devoid of a substituent at the 4-position and an N1-CH3 derivative. A P-4.50 IIIA4 cDNA clone was expressed in yeast and the partially purified protein was used in reconstituted systems containing NADPH-cytochrome P-450 reductase and cytochrome b5. This system catalyzed the oxidation of all of the 1,4-dihydropyridines except the two for which poor correlation was seen in the liver microsomes. Principal component analysis supported the view that most of these reactions were catalyzed by the same enzyme in the yeast P-450 IIIA4 preparation and in the different human liver microsomal preparations, or by a closely related enzyme showing nearly identical properties of catalytic specificity and regulation. The results indicate that the enzyme P-450 IIIA4 is probably the major human catalyst involved in the formal dehydrogenation of most but not all 1,4-dihydropyridine drugs.
