An experimental and theoretical study of the valence shell photoelectron spectrum of oxalyl chloride
Polarization dependent photoelectron spectra encompassing the outer valence orbitals of oxalyl chloride have been recorded in photon energy range 19–91 eV. These allowed anisotropy parameters and branching ratios to be determined. Photoionization partial cross sections calculated with Continuum Multiple Scattering – X? approach. Four are predicted possess a significant Cl 3p lone-pair character...
From CH2Cl2 and MeOH extracts of the stems of Cynomorium songaricum RUPR. (Cynomoriaceae), ursolic acid and its hydrogen malonate were isolated as inhibitors of human immunodeficiency virus type 1 (HIV-1) protease, with 50% inhibitory concentrations (IC50) of 8 and 6 microM, respectively. Amongst various synthesized dicarboxylic acid hemiesters of related triterpenes, inhibitory activity tended...
Ferrous ion and 2-oxoglutarate (2OG) oxygenases catalyze the demethylation of N(epsilon)-methylated lysine residues in histones. Here we report studies on the inhibition of the JMJD2 subfamily of histone demethylases, employing binding analyses by nondenaturing mass spectrometry (MS), dynamic combinatorial chemistry coupled to MS, turnover assays, and crystallography. The results of initial bin...
