Pharmaceutical compositions containing an FBPase inhibitor and an insulin sensitizer are provided as well as methods for treating diabetes and diseases responding to increased glycemic control, an improvement in insulin sensitivity, a reduction in insulin levels, or an enhancement of insulin secretion.
A series of Se-aryl carboselenothioates 3 (RCSSeAr, R=alkyl, aryl) were synthesized and characterized from the reaction of bis(thioacyl) sulfides 1 with sodium areneselenolates. The thionselenolesters 3 are stable (liquid or crystals) both thermally and to moisture. Reactions of 3 with aliphatic primary and secondary amines gave the corresponding ammonium carbodithioates 8 together with diphenyl diselenide
A novel method to synthesize isoquinolones via oxidative annulation of N‐alkoxy benzamides and alkynes using binaphthyl‐stabilized palladium nanoparticles (Pd‐BNP) as catalyst has been developed. This methodology affords various isoquinolone derivatives in good to excellent yields with high regioselectivities in the presence of air as oxidant. N‐Methoxybenzothioamide was also found to undergo oxidative

5-Oxodihydroisoxazoles react with thiocarbonyl chlorides to afford
N-thioacylisoxazol-5(2H)-ones which lose carbon
dioxide under photochemical conditions and undergo intramolecular
cyclisation of the iminocarbene to afford thiazoles. However, in some
cases loss of carbon dioxide is accompanied by loss of sulfur, giving
1,3-oxazin-6-ones.
Effect of Changing Electrophilic Center from CO to CS on Rates and Mechanism: Pyridinolyses of <i>O</i>-2,4-Dinitrophenyl Thionobenzoate and Its Oxygen Analogue
rate constants have been measured spectrophotometrically for the reactions of O-2,4-dinitrophenyl thionobenzoate (1) and 2,4-dinitrophenylbenzoate (2) with a series of substituted pyridines in 80 mol % H2O/20 mol % DMSO at 25.0 ± 0.1 °C. The Brønsted-type plots obtained are nonlinear with β1 = 0.26, β2 = 1.07, and pKa° = 7.5 for the reactions of 1 and β1 = 0.40, β2 = 0.90, and pKa° = 9.5 for the reactions
