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.

Electron interaction with deoxyribose analogue molecules in gaseous phase

We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3-hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 50 to 300 eV, has been given. The measurements of the cross sections were performed both as a function of scattering angle and incident electron energy and normalized to the absolute scale according to relative flow measurements and reliable calculations. The experimental elastic DCSs are compared with the most recent theoretical results. Both for elastic and inelastic scattering a special attention has been paid to investigate potential differences in electron scattering processes upon substitution of one of the H-atom in tetrahydrofuran by the OH group (in 3-hydroxytetrahydrofuran) or CH2OH group (in tetrahydrofurfuryl alcohol).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C4H8O2, you can also check out more blogs about453-20-3

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

Degradation mechanism of monosaccharides and xylan under pyrolytic conditions with theoretic modeling on the energy profiles

Xylan and three monosaccharides (mannose, galactose, and arabinose) were selected as model compounds to investigate the mechanism of hemicellulose pyrolysis. The evolution of several typical pyrolysis products were observed by thermogravimetric analysis coupled to Fourier transform infrared spectroscopy. Monosaccharides underwent similar pyrolysis routes involving ring opening and secondary decomposition. Breakage of the O-acetyl groups and 4-O-methylglucuronic acid units in xylan branches resulted in its different pyrolysis behavior for the formation of acetic acid, CO2, and CO. The detailed reaction pathways of the monosaccharides were studied using density functional theory calculations. Furfural formation was more favorable than the formation of 1-hydroxy-2-propanone and 4-hydroxydihydrofuran-2(3H)-one during xylose degradation. However, in the pyrolysis of mannose and galactose, formation of 5-hydroxymethyl-2-furaldehyde was preferred because of the high energy barrier of the dissociation of the hydroxymethyl group. Meanwhile, the breakage of O-acetyl groups leading to acetic acid formation easily occurred because of its lower energy barrier.

One-pot, three-component synthesis of 7-azaindole derivatives from N-substituted 2-amino-4-cyanopyrroles, various aldehydes, and active methylene compounds

An efficient and practical route to 7-azaindole framework has been developed by one-pot, three-component cyclocondensation of N-substituted 2-amino-4-cyanopyrroles, various aldehydes, and active methylene compounds in ethanol or acetic acid at reflux. Reactions involving tetronic acid, indane-1,3-dione, dimedone, and 5-phenylcyclohexane-1,3-dione gave carbocyclic fused 7-azaindoles, whereas Meldrum’s acid, benzoylacetonitrile, and malononitrile resulted in the highly substituted 7-azaindole derivatives, making this strategy very useful in diversity-oriented synthesis (DOS).
