Design, synthesis and biological evaluation of caudatin analogs as potent hepatitis B virus inhibitors

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. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 87392-05-0, help many people in the next few years.Recommanded Product: 87392-05-0

Synthesis of CMI-977, a potent 5-lipoxygenase inhibitor

CMI-977 is a potent 5-lipoxygenase inhibitor that intervenes in the production of leukotrienes and is presently being developed for the treatment of chronic asthma. It is a single enantiomer with an all-trans (2S,5S) configuration. Of the four isomers of CMI-977, the S,S isomer was found to have the best biological activity and was selected for further development. The enantiomerically pure product was synthesized on a 2-kg scale from (S)-(+)-hydroxymethyl-gamma-butyrolactone.

Modular Access to Chiral 2,3-Dihydrofurans and 3,4-Dihydro-2 H-pyrans by Stereospecific Activation of Formylcyclopropanes through Combination of Organocatalytic Reductive Coupling and Lewis-Acid-Catalyzed Annulative Ring-Opening Reactions

An organocatalytic reductive coupling and Lewis-acid-catalyzed annulative ring-opening strategy is developed as a two-step protocol for the stereoselective synthesis of dihydropyrans as the major products from the chiral formylcyclopropanes, CH acids, and Hantzsch ester. It is an efficient, catalytic, two-step protocol for the chiral synthesis of dihydropyrans and dihydrofurans. Structurally important and challenging functionally rich cyclopropanes containing cyclic-1,3-diones were synthesized in very good yields with excellent chemo-, enantio-, and diastereoselectivities from the readily available starting materials, chiral formylcyclopropanes, cyclic-1,3-diones, or CH acids and Hantzsch ester through an organocatalytic reductive coupling reaction at ambient conditions, especially without harming the cyclopropane ring. Chiral cyclopropanes containing cyclic-1,3-diones were stereospecifically transformed into dihydropyrans and dihydrofurans found in many bioactive natural products and drugs through an annulative ring-opening reaction by using Lewis-acid (BF3¡¤OEt2) or cesium carbonate (Cs2CO3) catalysis. Highly diastereo- and regioselective ring opening of cyclopropanes was explained through a stereospecific intimate ion pair pathway.

Modifier-substrate interactions of various types in the Orito reaction: Reversal of the enantioselection in the hydrogenation of ketopantolactone on Pt modified by beta-isocinchonine and O-phenylcinchonidine

The enantioselective hydrogenation of ketopantolactone (KPL) on Pt-alumina catalyst modified by beta-isocinchonine (beta-ICN) and O-phenylcinchonidine (PhOCD) in toluene, acetic acid and their mixtures under otherwise identical experimental conditions was studied. Reversal of the enantioselection was obtained dependent on the concentration of acetic acid (eemax = 17% (S) on Pt-PhOCD and 50% (R) on Pt-beta-ICN, respectively). The possible role in enantioselection of adducts forming in the reaction mixture and the stability of PhOCD under the conditions of the hydrogenation was investigated by ESI-MS. The results of the nonlinear phenomenon measurements on beta-ICN + PhOCD mixtures suggest that the intermediate surface complexes beta-ICN-KPL and PhOCD-KPL responsible for the opposite enantioselection include different types of interactions and the enantioselection is directed by the competition between these interactions.
