Apoptosis is a biological process relevant to several human diseases that is strongly regulated through protein-protein complex formation. We have previously reported a peptidomimetic compound as potent apoptotic modulator. Structural studies of this compound showed the presence of cis/trans isomers of the exocyclic tertiary amide bond in slow exchange. This information encouraged us to perform...

The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where  pyda  is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group Pī and two molecules per unit cell. The unit cell parameters are a=10.23...

Abstract. The atmospheric chemistry of 2,2,5,5-tetramethyloxolane (TMO), a promising “green” solvent replacement for toluene, was investigated in laboratory-based experiments and computational calculations. Results from both absolute relative rate studies demonstrated that the reaction OH + TMO (Reaction R1) proceeds with coefficient k1(296 K) = (3.1±0.4) ×10-12 cm3 molecule−1 s−1, factor 3 sma...

The oxidation of complexes of Ti(III), (TiL6)3+ (L=ur, Meur, DMeur, DEture, N-Bu-ur, and Phur), by iodine as I3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. The enthalpy of activation appears to decrease as ligand's size ...

2- Methylsulfonyl - 5- (1-methyl-5-nitro- 2 – imidazolyl ) 1,3,4 - thiadiazole ( 1 ) was prepared by twa independent routes.1) reaction of 1-methyl-2-formyl-5- nitroimidazole (3) with methyl hydrazinecarbodithioate gave the hydrazone 4. Reaction of compound 4 with acetic anhydride followed by potassium permanganate oxidation of the intermediate 5 gave the desired compound 1. 2) React...
