2,3-Di-O-methoxymethyl-6-O-tert-butyldimethylsilyl-gamma-cyclodextrin: A new class of cyclodextrin derivatives for gas chromatographic separation of enantiomers

Octakis(2,3-di-O-methoxymethyl-6-O-tert-butyldimethylsilyl) -gamma-cyclodextrin (2,3-MOM-6-TBDMS-gamma-CD) was employed as stationary phase for capillary gas chromatographic separation of enantiomers. Selective introduction of the acetal function at positions 2 and 3 of the glucose units was achieved by reaction of 6-O-TBDMS-gamma-cyclodextrin with methoxymethyl chloride. 2,3-MOM-6-TBDMS-gamma-CD was shown to be a chiral stationary phase suitable for enantiodifferentiation of a broad spectrum of chiral volatiles from various chemical classes. A total of 125 pairs of enantiomers could be separated. Structural influences of the analytes on the enantioseparation were demonstrated. High alpha values up to 1.8 were observed for the hydroxyketone acetoin and some methyl branched ketones. Pronounced enantioseparations were also determined for cyclic pentenolone and furanone derivatives.

Synthesis of stable nitrile oxide compounds

This invention discloses a process for the synthesis of stable aryl nitrile oxides which comprises the sequential steps of (1) halomethylating a halomethyl group onto a substituted aromatic compounds wherein said halomethyl group is halomethylated onto a position that is ortho to at least one of the substituent groups on the substituted aromatic compound; (2) converting the ortho halomethylated-substituted aromatic compound into an ortho-substituted aromatic aldehyde by reacting the ortho halomethylated-substituted aromatic compound with a salt selected from the group consisting of sodium 2-nitropropane and potassium 2-nitropropane in a lower alcohol solvent; (3) converting the ortho-substituted aromatic aldehyde into an ortho-substituted aromatic; and (4) converting the ortho-substituted aromatic oxime into the ortho-substituted aryl nitrile oxide by reacting the ortho-substituted aromatic oxime with an aqueous sodium hypochlorite solution.

Discovery of Selective Phosphodiesterase 1 Inhibitors with Memory Enhancing Properties

A series of potent thienotriazolopyrimidinone-based PDE1 inhibitors was discovered. X-ray crystal structures of example compounds from this series in complex with the catalytic domain of PDE1B and PDE10A were determined, allowing optimization of PDE1B potency and PDE selectivity. Reduction of hERG affinity led to greater than a 3000-fold selectivity for PDE1B over hERG. 6-(4-Methoxybenzyl)-9-((tetrahydro-2H-pyran-4-yl)methyl)-8,9,10,11-tetrahydropyrido[4?,3?:4,5]thieno[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-5(6H)-one was identified as an orally bioavailable and brain penetrating PDE1B enzyme inhibitor with potent memory-enhancing effects in a rat model of object recognition memory.

Lactonization is the critical first step in the disposition of the 3-hydroxy-3-methylglutaryl-CoA reductase inhibitor atorvastatin

In an in vitro study, we compared the cytochrome P450 (CYP)-dependent metabolism and drug interactions of the acid and lactone forms of the 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase inhibitor atorvastatin. Metabolism of atorvastatin acid and lactone by human liver microsomes resulted in para-hydroxy and ortho-hydroxy metabolites. Both substrates were metabolized mainly by CYP3A4 and CYP3A5. Atorvastatin lactone had a significantly higher affinity to CYP3A4 than the acid (K(m): para-hydroxy atorvastatin, 25.6 ¡À 5.0 muM; para-hydroxy atorvastatin lactone, 1.4 ¡À 0.2 muM; ortho-hydroxy atorvastatin, 29.7 ¡À 9.4 muM; and ortho-hydroxy atorvastatin lactone, 3.9 ¡À 0.2 muM). Compared with atorvastatin acid, CYP-dependent metabolism of atorvastatin lactone to its para-hydroxy metabolite was 83-fold higher [formation CL(int) [V(max)/K(m)): lactone 2949 ¡À 3511 versus acid 35.5 ¡À 48.1 mul ¡¤ min-1 ¡¤ mg-1] and to its ortho-hydroxy metabolite was 20-fold higher (CL(int): lactone 923 ¡À 965 versus acid 45.8 ¡À 59.1 mul ¡¤ min-1 ¡¤ mg-1). Atorvastatin lactone inhibited the metabolism of atorvastatin acid by human liver microsomes with an inhibition constant (K(i)) of 0.9 muM while the K(i) for inhibition of atorvastatin by atorvastatin lactone was 90 muM. Binding free energy calculations of atorvastatin acid and atorvastatin lactone complexed with CYP3A4 revealed that the smaller desolvation energy of the neutral lactone compared with the anionic acid is the dominant contribution to the higher binding affinity of the lactone rather than an entropy advantage. Because atorvastatin lactone has a significantly higher metabolic clearance and the lactone is a strong inhibitor of atorvastafin acid metabolism, it can be expected that metabolism of the lactone is the relevant pathway for atorvastatin elimination and drug interactions. We hypothesize that most of the open acid metabolites present in human plasma are generated by interconversion of lactone metabolites.

Synthesis and Biological Evaluation of Novel Carbohydrate-Derived Derivatives of Erlotinib

(Table presented.). A series of novel carbohydrate-derived Erlotinib derivatives were prepared by the copper-catalyzed cycloaddition reaction of erlotinib with various azido-sugars. The structures of the newly synthesized compounds were characterized and their cytostatic effects evaluated in vitro on human cancer cell lines MDA-MB-231, HEPG-2, A549, and MCF-7 using an MTS assay. The novel erlotinib derivatives had the expected inhibitory effects on MDA-MB-231 and HEPG-2 cell llines. Among the compounds evaluated the carbohydrate-derived compounds 5b, 5d, 6a, and 6c had more potent activities against MDA-MB-231 or HEPG-2 than Erlotinib. Drug Dev Res, 2016.
