Stereoselective interaction between tetrahydropalmatine enantiomers and CYP enzymes in human liver microsomes

Tetrahydropalmatine (THP), with one chiral center, is an alkaloid that possesses analgesic and many other pharmacological actives. The aim of the present study is to investigate stereoselective metabolism of THP enantiomers in human liver microsomes (HLM) and elucidate which cytochrome P450 (CYP) isoforms contribute to the stereoselective metabolism in HLM. Additionally, the inhibitions of THP enantiomers on activity of CYP enzymes are also investigated. The results demonstrated that (+)-THP was preferentially metabolized by HLM. Ketoconazole (inhibitor of CYP3A4/5) inhibited metabolism of (-)-THP or (+)-THP at same degree, whereas the inhibition of fluvoxamine (inhibitor of CYP1A2) on metabolism of (+)-THP was greater than that of (-)-THP; moreover, the metabolic rate of (+)-THP was 5.3-fold of (-)-THP in recombinant human CYP1A2. Meanwhile, THP enantiomers did not show obvious inhibitory effect on the activity of various CYP isoforms (CYP1A2, 2A6, 2C8, 2C9, 2C19, 2E1, and 3A4/5), whereas (-)-THP, but not (+)-THP, significantly inhibited the activity of CYP2D6 with the Ki value of 6.42 ¡À 0.38 muM. The results suggested that THP enantiomers were predominantly metabolized by CYP3A4/5 and CYP1A2 in HLM, and (+)-THP was preferentially metabolized by CYP1A2, whereas CYP3A4/5 contributed equally to metabolism of (-)-THP or (+)-THP. Besides, the inhibition of CYP2D6 by (-)-THP may cause drug-drug interaction, which should be considered. Copyright

AlCl3-Promoted Synthesis of 2-Mercapto Benzoheterocycles by Using Sodium Dimethyldithiocarbamate as Thiocarbonyl Surrogate

A simple, expeditious and high-efficiency synthetic method for the AlCl3-mediated one-pot preparation of 2-mercapto benzoheterocycles (2-mercapto benzothiazoles, benzoxazoles and benzimidazoles) is described. By the treatment of a series of S, O and N heteroatoms containing bifunctional molecules with sodium dimethyldithiocarbamate in AlCl3, the desired benzoheterocycles are obtained smoothly. The protocol can also be applied on the synthesis of a series of thiazolidine-2-thiones, imidazolidine-2-thiones. This novel synthetic approach has advantages such as ligand-free, high efficiency, short reaction time, readily available starting materials and simple experimental procedures.

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.Computed Properties of C8H7NOS, you can also check out more blogs about22876-22-8

Oxa-Michael Addition to alpha,beta-Unsaturated Nitriles: An Expedient Route to gamma-Amino Alcohols and Derivatives

Water addition to alpha,beta-unsaturated nitriles would give facile access to the beta-hydroxy-nitriles, which in turn can be hydrogenated to the gamma-amino alcohols. We have previously shown that alcohols readily add in 1,4-fashion to these substrates using Milstein’s Ru(PNN) pincer complex as catalyst. However, attempted water addition to alpha,beta-unsaturated nitriles gave the 3-hydroxynitriles in mediocre yields. On the other hand, addition of benzyl alcohol proceeded in excellent yields for a variety of beta-substituted unsaturated nitriles. Subsequent treatment of the benzyl alcohol addition products with TMSCl/FeCl3 resulted in the formation of 3-hydroxy-alkylnitriles. The 3-benzyloxy-alkylnitriles obtained from oxa-Michael addition also could be hydrogenated directly in the presence of acid to give the amino alcohols as their HCl salts in excellent yields. Hydrogenation under neutral conditions gave a mixture of the secondary and tertiary amines. Hydrogenation in the presence of base and Boc-anhydride gave the orthogonally bis-protected amino alcohols, in which the benzyl ether can subsequently be cleaved to yield Boc-protected amino alcohols. Thus, a variety of molecular scaffolds with a 1,3-relationship between O- and N-functional group is accessible starting from oxa-Michael addition of benzyl alcohol to alpha,beta-unsaturated nitriles.

Solubility of bis(benzoxazolyl-2-methyl) sulfide in different pure solvents and ethanol + water binary mixtures between (273.25 and 325.25) K

The solubilities of bis(benzoxazolyl-2-methyl) sulfide in ethanol, 1-butanol, 2-propanol, chlorobenzene, toluene, o-xylene, and ethanol + water were measured by a synthetic method. The laser monitoring observation technique was used to determine the disappearance of the solid phase in the solid + liquid mixture. All data were measured in the temperature range from (273.25 to 325.25) K at atmosphere pressure. The effect of solvent composition and temperature on the solubility was discussed. For all solvents studied, the data are well fitted with a semiempirical Apelblat equation.

Wadsworth-Emmons reaction: The unique catalytic reaction by a solid base

The near-stoichiometric amount of bases is used both in laboratory and industry in Wadsworth-Emmons (WE) reactions, since the by-product, (EtO) 2P(O)OH, formed in the reaction neutralizes the base into an inert salt. A strategy to design, develop, and evolve the recyclable Mg-Al-hydrotalcite-OtBu (HT-OtBu) by the interaction of KOtBu with the calcined hydrotalcite that transforms a well-defined stoichiometric WE reaction into a catalytic one in an effort to minimize the quantum of effluents released and reduce the cost of the process is described here. HT-OtBu is found to be an efficient solid base for WE reactions for the simple synthesis of alpha,beta-unsaturated esters and nitriles for the first time. The HT-OtBu, composed of various ratios of Mg/Al (i.e., 2, 2.5, and 3) and different contents of tBuO – (Mg/Al:3), and their precursors were prepared and well characterized to draw a correlation between structure and reactivity of the hydrotalcites in WE reactions.
