Reactive oxygen species biosynthesis

The production of reactive oxygen species e.g. superoxides is implicated in the biosynthesis of prostaglandins from arachidonic acid during tissue inflammation. Oxygen can be reduced to superoxide by plasma membrane bound NADPH-oxidase in rabbit and human cell neutrophils. The tsitsixenicins inhibited (> 80% at a concentration of approximately 30 pM) the production of superoxide in isolated rabbit neutrophils with only 94 retaining this level of activity on ten-fold dilution. The results observed with rabbit neutrophils cannot usually be directly extrapolated to human neutrophils and only 93 and 94 exhibited moderate activity when the assay was repeated using the latter neutrophils [91]-... [Pg.90]

Homopantothenic acid, which is not a coenzyme A precursor, did not exert a protective effect against reactive oxygen species (Slyshenov et al. 1995). Slyshenov et al. (1995, 1995, 1998, 1999) therefore proposed that the observed protective effects of pantothenic acid and some of its derivatives against cell and tissue injury may be due to stimulation of biosynthesis of coenzyme A and glutathione. [Pg.174]
