(E)-3-Phenyl-1-(2-pyrrolyl)-2-propenone (PPP) is a pyrrole derivative of chalcone, in which the B-ring of chalcone linked to β-carbon is replaced by pyrrole group. While pyrrole has been studied for possible Src inhibition activity, chalcone, especi

The 1H and 13C chemical shifts and the mass spectral fragmentation patterns of 1-aryl-3-phenylpropanes with m- or p-substituents (H, NO2 , Br, Cl, OCH3 , CH3 ) were studied. The electronic effects of the substituents seemed to be transmitted by the t

1H and 13C NMR spectra of aryl esters of propionic acid, acrylic acid, and propiolic acid were systematically examined to find out the substituent effect on the chemical shift. The values of the chemical shift of the carbonyl carbon showed an inverse

Primary kinetic isotope effects (KIEs), k(H)/k(D), have been determined spectrophotometrically for the reactions of NAD(+) analogues (acridinium ions, 1a-e(+), and quinolinium ion, 2(+)) with heteroaromatic compounds such as 3-methyl-2-phenylbenzothi
