A series of 4(3H)-quinazolinone derivatives with dithiocarbamate side chains were synthesized and tested for their in vitro antitumor activity against human myelogenous leukemia K562 cells. Among them, (3,4-dihydro-2-methyl-4-oxoquinazolin-6-yl)methyl 4-(4-fluorophenyl)piperazine-1-carbodithioate 8q exhibited significant inhibitory activity against K562 cells with IC(50) value

Three diversity points of 4(3H)-quinazolinone are introduced at the 3-, 6-, and 7-positions with an efficient parallel solution-phase synthetic method. A one-pot synthesis was developed that gave the key intermediate in high yield. Five hit compounds exhibit preferable activities against
Ischemia-reperfusion induces reactive oxygen species (ROS) formation, and ROS lead to cardiac dysfunction, in part, via the activation of the nuclear poly(ADP-ribose) polymerase (PARP, called also PARS and ADP-RT). ROS and peroxynitrite induce single-strand DNA break formation and PARP activation

Fifteen new derivatives of quinazolin-4-one bearing the 2-furyl moiety at position 2 and a substituted phenyl moiety at position 3 were designed and synthesized to be evaluated as cytotoxic agents. Their chemical structures were confirmed by spectral and elemental analysis;
Oxidants such as H(2)O(2) can induce a low level of apoptosis at low concentrations but at higher concentrations cause necrosis. Higher concentrations of H(2)O(2) also inhibit the induction of apoptosis by chemotherapy drugs. One theory is that, at higher concentrations
