Activation of poly(ADP-ribose) synthetase (PARS, also termed polyADP-ribose polymerase or PARP) has been proposed as a major mechanism contributing to beta-cell destruction in type I diabetes. In the present study, we have investigated the role of PARS in mediating the induction of diabetes and
Peroxynitrite triggers DNA single-strand breakage, which activates the nuclear enzyme poly(ADP-ribose) synthetase (PARS). Activation of PARS depletes its substrate, NAD+, slowing the rate of glycolysis, electron transport, and ATP formation, resulting in cell necrosis. Here, we demonstrate that
Chronic inflammation is known to facilitate carcinogenic transformation in various tissues. 5-iodo-6-amino-1,2-benzopyrone (INH2BP), a novel inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (pADPRT) has recently been shown to regulate a variety of cellular signal transduction pathways and
Coumarin as well as its derivatives 7-OH coumarin and 4-OH coumarin were found to stimulate interleukin-1 beta (IL-1 beta) release from freshly isolated human mononuclear cells (MNC) if the culture medium contained fetal calf serum. Under serum-free conditions, almost no induction of IL-1 beta
The comparison of the antioxidant activity of some coumarins with their molecular structure is well determined. However, the protective function of coumarins with various chemical structures against liver toxicity has not yet been well established. Therefore, the aim of this study was to evaluate
Coumarin is the basic structure of numerous naturally occurring compounds with important and diverse physiological activities. More than a thousand coumarin derivatives have been described, varying from simple coumarins containing alkyl and hydroxyl side chains to complex coumarins with benzoyl,
BACKGROUND
Ageratum conyzoides Linn (Asteraceae), a tropical plant that is very common in West Africa and some parts of Asia and South America, has been used to treat inflammatory disorders. In Brazil, teas made from A. conyzoides L. are used as anti-inflammatory, analgesic and anti-diarrheic
