One aspect of this disclosure relates generally to lipid compounds that exert diverse effects in the endocannabinoid system, such as regulating CB1 and CB2 receptor or moderating other bio-macromolecules within the endocannabinoid system. Some of the compounds showed improved receptor binding affinity, and/or improved receptor subtype selectivity, and improved bio-stability. Some of the compounds exhibit activities to regulate the enzymes that moderate the bio-disposal of endogenous cannabinoids, such as the fatty acid amide hydrolase (FAAH). Some of the compounds exhibit activities to inhibit the anandamide transporter. Other aspects of the invention are pharmaceutical preparations employing these ligands and methods of administering therapeutically effective amounts of the preparations to provide a physiological effect.

Glycerol dehydrogenase (GDH, EC 1.1.1.6, from Enterobacter aerogenes or Cellulomonas sp.) catalyzes the interconversion of analogues of glycerol and dihydroxyacetone.Its substrate specificity is quite different from than of horse liver alcohol dehydrogenase (HLADH), yeast alcohol dehydrogenase, and other alcohol dehydrogenases used in enzyme-catalyzed organic synthesis and is thus a useful new enzymic catalyst for the synthesis of enantiomerically enriched and isotopically labeled organic molecules.This paper illustrates synthetic applications of GDH as a reduction catalyst by the enantioselective reduction of 1-hydroxy-2-propanone and 1-hydroxy-2-butanone to the corresponding R 1,2-diols (ee = 95-98percent). (R)-1,2-Butanediol-2-d1 was prepared by using formate-d1 as the ultimate reducing agent.Comparison of (R)-1,2-butanediol prepared by reduction of 1-hydroxy-2-butanone enzymatically and with actively fermenting bakers’ yeast indicated than yield and enantiomeric purity were similar by the two procedures.Reactions proceeding in the direction of substrate oxidation usually suffer from slow rates and incomplete conversions due to product inhibition.The kinetic consequences of product inhibition (competitive, noncompetitive, and mixed) for practical synthetic applications of GDH, HLADH, and other oxidoreductases are analyzed.In general, product inhibition seems the most serious limitation to the use of these enzymes as oxidation catalysts in organic synthesis.

A number of methyl derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and tested in vitro for anti-herpes and anti- human immunodeficiency virus (HIV) activity. Among these analogues, (R)-2′- methyl-PMEG [(R)-3] and 2′,2′-dimethyl-PMEG (7) demonstrated potent anti-HIV activity in the XTT-assay with EC50 values of 1.0 and 2.6 muM, respectively. The corresponding (S)-2′-methyl-PMEG [(S)-3] was found to be less potent against HIV. In addition, the (R) and (S) enantiomers of 9-[3- hydroxy-2-(phosphonomethoxy)propyl]guanine (HPMPG, 8) were prepared for comparison of biological activity, and shown to be active and equipotent against herpesviruses, but inactive against HIV.

We report a practical one-pot synthesis of dialkylammonium salts of anionic dinuclear ruthenium complexes having chelating diphosphine ligands, BINAPs and DPB, with formula of [NEt2H2][{RuCl(diphosphine)}2(mu-Cl) 3] [2a: diphosphine = 2,2?-bis-(diphenylphosphino)-1,1?-binaphthyl; 6a: 2,2?-bis(di(p-tolyl)phosphino)-1,1?-binaphthyl; 8a: 1,2-bis(diphenylphosphino)benzene]. Treatment of cationic ruthenium complexes, [RuCl(eta6-p-cymene)(diphosphine)]Cl (4) with a slight excess of NEt2H2Cl (5a) afforded 2a, 6a, and 8a in quantitative yields. Similar reactions with various dialkylammonium salts 5b-f gave the corresponding salts, [NR2H2][{RuCl(diphosphine)}2(mu-Cl) 3]. A one-pot mixture of BINAP or its derivative, [RuCl2(eta6-arene)]2, and NR2H2Cl produced salts of the anionic dinuclear complexes which can be applied as catalysts for the asymmetric hydrogenation of ketonic substrates such as acetol and methyl acetoacetate with high activity and high enantioselectivity. The anionic face-sharing bioctahedral structure of these complexes was confirmed by the X-ray analysis of 8a, which has two hydrogen bonds between two NH of the diethylammonium cation and two terminal chloro-ligands.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Reference of 4254-15-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4254-15-3, in my other articles.

The liver X receptors (LXR) play a key role in cholesterol homeostasis and lipid metabolism. SAR studies around tertiary-amine lead molecule 2, an LXR full agonist, revealed that steric and conformational changes to the acetic acid and propanolamine groups produce dramatic effects on agonist efficacy and potency. The new analogs possess good functional activity, demonstrating the ability to upregulate LXR target genes, as well as promote cholesterol efflux in macrophages.
