The synthesis and pharmacological activities of the four stereoisomers of methyl tetrahydrofuran-2-ylmethyl 2,6-dimethyl-4-(2′-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate (furnidipine) are reported.The four isomers were synthesized by a modified Hantzsch synthesis by reaction of (-)- or (+)-tetrahydrofuran-2-ylmethyl 3-aminocrotonate and methyl 2-<(2'-nitrophenyl)methylene>acetoacetate or, alternatively, by reaction of (-)- or (+)-tetrahydrofuran-2-ylmethyl 2-<(2'-nitrophenyl)methylene>acetoacetate and methyl 3-aminocrotonate.The 1:1 diasteromeric mixture thus obtained were separated by chromatography, using poly(D-phenylglycine) as the chiral stationary phase.The enantiomeric purity of the stereoisomers was determined by high-performance liquid chromatography-chiral stationary phase technique (HPLC-CSP).Attempts to obtain crystals of a single stereoisomer failed in different solvent, while methanol crystallization of the product obtained from (+/-)-tetrahydrofuran-2-ylmethyl 2-<(2'-nitrophenyl)methylene>acetoacetate and methyl 3-aminocrotonate yielded good-quality crystals of the most insoluble racemate which proved to be a mixture of the (SS)/(RR) enantiomers by X-ray crystaloography.Conformational analysis of the stereoisomers, assuming rotation of the aryl substituent and ester groups, shows small energy differences (about 4 kcal*mol-1) between the most and the least favorable conformations.Binding studies were performed using <3H>isradipine as a reference ligand.The results showed stereospecificity of the furnidipine isomers in brain, ileum, and cardiac tissues, the (SS) and (SR)-isomers clearly being more potent than their (RR)- and (RS)-enantiomers.The (SS)- and (SR)-isomers were also more selective on cerebral tissue when compared with ileal and cardiac preparations.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research. Formula: C5H8O3

(Chemical Equation Presented) The size and shape of the chiral cavity of a macrocyclic receptor were tuned by the alteration of the binaphthyl moiety to improve the chiral recognition/discrimination ability. For example, host 3 with the 3,5-bis(trifluoromethyl)phenyl group at the 3,3?-positions showed improved enantioselectivity for small molecules such as 2-chloropropionic acid and methyl lactate as evaluated by the binding constants. This host 3 also had an excellent ability as an NMR chiral solvating agent.

Thirty-nine caudatin analogs were designed and synthesized. Their anti-hepatitis B virus (HBV) activities were evaluated in vitro. Among them, twenty-three compounds showed much better anti-HBV activity than caudatin, and eleven compounds significantly inhibited the HBV DNA replication with IC50 values < 10 muM. Interestingly, three compounds (22, 28, 29) exhibited excellent activity against the secretion of HBsAg (IC50 = 63.02 muM, 52.81 muM, 56.08 muM), HBeAg (IC50 = 204.80 muM, 173.51 muM, 70.39 muM), along with HBV DNA replication (IC50 = 24.55 muM, 5.69 muM, 8.23 muM) with lower cytotoxicity. The structure-activity relationships (SARs) of these caudatin analogs were also discussed. If you are interested in 87392-05-0, you can contact me at any time and look forward to more communication.
