Effect of a phosphazene base on the diastereoselectivity of addition of alpha-sulfonyl carbanions to butyraldehyde and isopropylideneglyceraldehyde

The effect of tBuP4, a strong and cation-free base, on the yield and diastereoselectivity of additions of thus formed “naked” alpha-sulfonyl carbanions to achiral butyraldehyde and chiral isopropylideneglyceraldehyde was studied. It has been found that with tBuP4 a reasonable yield (?55%) and a slightly better diastereoselectivity (72% of the anti diastreomer) are obtained with achiral and nonfunctionalized butyraldehyde while with isopropylideneglyceraldehyde the use of tBuP4 allowed us to greatly increase the yields (up to 95-100%) and the diastereoselectivities (83-89% of a single diastereomer over the four possible diastereomers). It was also shown that the extra oxygen atom in the alpha-position plays a determinant role in this effect.

Process for producing intermediate furanones from diol derivative and thionyl chloride

A novel process for the manufacture of the furanone of the formula STR1 is described. In this process, a diol is firstly reacted with thionyl chloride, then the sulphite formed, optionally after oxidation to the corresponding sulphate, is treated with sodium cyanide and the resulting hydroxynitrile is hydrolyzed. The furanone of formula I can be used as a starting material for the manufacture of R-(-)-pantolactone.

Discovery of a Novel Small-Molecule Modulator of C-X-C Chemokine Receptor Type 7 as a Treatment for Cardiac Fibrosis

C-X-C chemokine receptor type 7 (CXCR7) is involved in cardiac and immune pathophysiology. We report the discovery of a novel 1,4-diazepine CXCR7 modulator, demonstrating for the first time the role of pharmacological CXCR7 intervention in cardiac repair. Structure-activity-relationship (SAR) studies demonstrated that a net reduction in lipophilicity (log D) and an incorporation of saturated ring systems yielded compounds with good CXCR7 potencies and improvements in oxidative metabolic stability in human-liver microsomes (HLM). Tethering an ethylene amide further improved the selectivity profile (e.g., for compound 18, CXCR7 Ki = 13 nM, adrenergic alpha 1a Kb > 10-»000 nM, and adrenergic beta 2 Kb > 10-»000 nM). The subcutaneous administration of 18 in mice led to a statistically significant increase in circulating concentrations of plasma stromal-cell-derived factor 1alpha (SDF-1alpha) of approximately 2-fold. Chronic dosing of compound 18 in a mouse model of isoproterenol-induced cardiac injury further resulted in a statistically significant reduction of cardiac fibrosis.

Effect of drying and storage on the volatile compounds of jujube fruit detected by electronic nose and GC-MS

Dried jujube fruit has been wildly used as flavoring in food preparation and food industry because of its unique and exquisite flavor. However, there is limited information available on the formation and alteration of jujube flavor during drying and storage. In this study, the effects of drying and storage on the volatiles in jujube fruit were investigated by electronic nose and GC-MS. Electronic nose and GC-MS could distinguish different jujube samples clearly; the ester and aldehydes showed significant decreases during drying, while furans and pyrazines were generated and increased with heat time; the esters, aldehydes, furans and pyrazines showed significant decreases, and some of them even disappeared during storage, while acids and terpenes increased with the extension of storage. Based on the present results, furans and pyrazines, generated during drying, are the predominant components of the unique and exquisite flavor of dried jujube, and these compounds could be negatively in?uenced because of evaporation, oxidation and degradation of jujube volatiles during storage.

Structure-based design, synthesis, and biological evaluation of irreversible human rhinovirus 3C protease inhibitors. 6. Structure-activity studies of orally bioavailable, 2-pyridone-containing peptidomimetics

The structure-based design, chemical synthesis, and biological evaluation of various 2-pyridone-containing human rhinovirus (HRV) 3C protease (3CP) inhibitors are described. These compounds are comprised of a peptidomimetic binding determinant and a Michael acceptor moiety, which forms an irreversible covalent adduct with the active site cysteine residue of the 3C enzyme. The 2-pyridone-containing inhibitors typically display improved 3CP inhibition properties relative to related peptide-derived molecules along with more favorable antiviral properties. The cocrystal structure of one pyridone-derived 3CP inhibitor complexed with HRV-2 3CP is also described along with certain ab initio conformation analyses. Optimization of the 2-pyridone-containing compounds is shown to provide several highly active 3CP inhibitors (kobs/[I] > 500 000 M-1 s-1) that function as potent antirhinoviral agents (EC50 = <0.05 muM) against multiple virus serotypes in cell culture. One 2-pyridone-containing 3CP inhibitor is shown to be bioavailable in the dog after oral dosing (F = 48%).
