The first total synthesis of (R)-convolutamydine A has been achieved by the organocatalytic addition of acetone to 4,6-dibromoisatin. The absolute configuration was determined by single crystal X-ray diffraction. DFT studies were used to model the tr

The Sonogashira–Heck–Cassar reaction of ferrocenylacetylene with aryl- and heteroaryl halides was shown to be a facile and convenient route for the synthesis of 1-ferrocenyl-2-aryl- and 1-ferrocenyl-2-heteroarylacetylenes in high yields. Addition

Convolutamydine A, an oxindole that originated from a marine bryozoan, has several biological effects. In this study, we aimed to investigate the antinociceptive effects of convolutamydine A and two new synthetic analogues.Convolutamydine A and the t

Isatin is a versatile compound with a diversity of effects. We designed to investigate the inhibitory effect of isatin derivatives on lipopolysaccharide/interferon-gamma-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-
