N-acetyl-l-cysteine (NAC) is a well-known antioxidant that is capable of facilitating glutathione (GSH) biosynthesis and replenishing intracellular GSH under oxidatively challenging circumstances. N-acetyl-cysteine-amide (NACA), the amide form of NAC, is a newly designed and synthesized thiol-containing compound which is believed to be more lipophilic and permeable through cell membranes than N...

1. The chief sulphur-containing metabolite of styrene and sytrene oxide in the rabbit and rat is chromatographically identical with N-acetyl-S-(beta-hydroxyphenethyl)-l-cysteine and this compound is also formed, together with N-acetyl-S-phenethyl-l-cysteine, as a metabolite of phenethyl bromide. 2. The amounts of the phenethylmercapturic acid and its hydroxy derivative excreted in the urine of ...

PURPOSE To investigate the copaiba oil on the hepatic damage induced by acetaminophen, comparing against corn oil. METHODS Fifty four rats were distributed into nine study groups (N=6): control group, that didn't receive the acetaminophen; Acetaminophen Group, that only received the acetaminophen; Prophylactic Copaiba Group 1, that received copaiba oil two hours before the acetaminophen; Prop...

background: poly cystic ovarian syndrome (pcos) is the most prevalent endocrinopathy among women and the most common underlying diagnosis for anovulatory infertility. the role of insulin-resistance (ir) and hyperinsulinemia in pathophysiology and clinical manifestations of the syndrome depicts the importance of evaluation of the efficacy of insulin reducing medications. n acetyl cysteine (nac) ...

Recent discoveries of important pharmacological properties have drawn attention to the reactivity of HNO (azanone, nitroxyl) with biologically relevant substrates. Apart from its role in thiol oxidation, HNO has been reported to have nitrosative properties, for example, with tryptophan resulting in N-nitrosotryptophan formation. We have investigated the reactivity of HNO with tryptophan and sma...
