Aging is associated with increase in chronic disease as well as infections and associated morbidity. This is often throughout to be secondary immunosenescene. Whether this decline in immune function with aging is due to the aging process per Se or is secondary to poor health, inflammation, and other life style factors particularly suboptimal nutritional status. With aging a variety of changes are observed in the immune system, which translate into less effective innate and adaptive immune responses and in creased susceptibility to infections. Antioxidant vitamins and trace elements [vitamins C, E, selenium, copper and zinc] counteract potential damage caused by reactive oxygen species to cellular tissues and modulate immune cell function through regulation of redoxsensitive transcription factors and affect production of cytokines and prostaglandins. Adequate intake of vitamins B[6], folate, B[12], C,E, and of selenium, Zn, copper and iron supports a Th I cytokine-mediated immune response with sufficient production of proinflammatory cytokine. Vitamin A and D play important roles in both cell mediated and humoral antibody response. Nutrient supplementation is often accompanied by an improvement in immune function.

Over 170 million people are chronically infected by the hepatitis C virus (HCV) andat risk fordyingfromliver cirrhosis and hepatocellular carcinoma. Current therapy is expensive, associated with significant side effects, and often ineffective. Discovery of antiviral compounds against HCV traditionally involves a priori target identification followed by biochemical screening and confirmation in cell-based replicon assays. Typically, this results in the discovery of compounds that address a few predetermined targets and are prone to select for escape variants. To attempt to identify antiviral compounds with broad target specificity, we developed an unbiased cell-based screening system involving multiple rounds of infection in a 96-well format. Analysis of a publicly available library of 446 clinically approved drugs identified 33 compounds that targeted both known and previously unexplored aspects of HCV infection, including entry, replication, and assembly.Discovery ofnovel viral and cellular targets in this manner will broaden the therapeutic armamentarium against this virus, allowing for the development of drug mixtures that should reduce the likelihood of mutational escape.

We have recently observed that S-(2-hydroxyethylmercapto)-L-cysteine (L-CySSME), the mixed disulfide of L-cysteine and 2-mercaptoethanol, prevented cataracts induced in mice by acetaminophen (ACP) by functioning as a prodrug of L-cysteine and protecting the liver. This prompted the evaluation of the more lipophilic N-acetyl (Ac-CySSME) and ethyl ester (Et-CySSME) derivatives of L-CySSME as proprodrug forms, as well as the “D” enantiomer, as hepatoprotective agents. Serum ALT levels were measured at 24 hours after a toxic but nonlethal dose of ACP that insured 48 hour survival of the animals. Since the increases in ALT produced were highly variable (even after log transformation) and complicated the statistical analyses, we calculated confidence intervals for the mean ALT levels for each treatment group. This enabled comparisons to be made of the efficacy of L-CySSME as well as Ac-CySSME and Et-CySSME with other representative prodrugs of L-cysteine, namely, 2(RS)-methylthiazolidine-4(R)-carboxylic acid (MTCA), L-2-oxothiazolidine-4-carboxylic acid (OTCA), and N-acetyl-L-cysteine (NAC), in protecting the liver. It was shown that L-CySSME and MTCA administered intraperitoneally at 2.5 mmol/kg were superior to the other cysteine prodrugs at equimolar doses in protecting mice from hepatotoxicity elicited by a 400 mg/kg (2.65 mmol/kg) dose of ACP given i.p. 30 minutes prior to the prodrugs. The “D” form of CySSME was totally without protective effect. Oral doses of the prodrugs even at 2x the i.p. dose were less effective, although MTCA was the most protective.

Oxidative stress and glutathione (GSH) deficit may play an important role in HIV infection pathogenesis, and oral administration of GSH- replenishing drugs such as N-acetylcysteine (NAC) and 2-oxothiazolidine-4(R)- carboxylic acid (OTC) may be associated with an increased survival rate of HIV-infected patients. Nevertheless, beneficial effects of these molecules are restricted in vivo by the high concentrations that are necessary to obtain biological effects, rapid extracellular metabolization, and low availability and plasma concentrations. We synthesized OTC derivatives that are more lipophilic than OTC and theoretically able to overcome these limitations and to generate, in addition to cysteine, other substrates of the gamma-glutamyl cycle. Their antiviral effects were investigated in human HIV- 1/ba-l-infected monocyte-derived macrophages. In our experimental conditions, OTC exhibited anti-HIV-1 effects and little cytotoxicity at high doses. None of the nine tested derivatives showed higher cytotoxicity than OTC, nor anti- HIV-1/Ba-L activity.

Cigarette/tobacco smoke/biomass fuel-induced oxidative and aldehyde/carbonyl stress are intimately associated with the progression and exacerbation of chronic obstructive pulmonary disease (COPD). Therefore, targeting systemic and local oxidative stress with antioxidants/redox modulating agents, or boosting the endogenous levels of antioxidants are likely to have beneficial effects in the treatment/management of COPD. Various antioxidant agents, such as thiol molecules (glutathione and mucolytic drugs, such as N-acetyl-L-cysteine and N-acystelyn, erdosteine, fudosteine, ergothioneine, and carbocysteine), have been reported to modulate various cellular and biochemical aspects of COPD. These antioxidants have been found to scavenge and detoxify free radicals and oxidants, regulate of glutathione biosynthesis, control nuclear factor-kappaB (NF-kappaB) activation, and hence inhibiting inflammatory gene expression. Synthetic molecules, such as specific spin traps like alpha-phenyl-N-tert-butyl nitrone, a catalytic antioxidant (ECSOD mimetic), porphyrins (AEOL 10150 and AEOL 10113), and a superoxide dismutase mimetic M40419, iNOS and myeloperoxidase inhibitors, lipid peroxidation inhibitors/blockers edaravone, and lazaroids/tirilazad have also been shown to have beneficial effects by inhibiting cigarette smoke-induced inflammatory responses and other carbonyl/oxidative stress-induced cellular alterations. A variety of oxidants, free radicals, and carbonyls/aldehydes are implicated in the pathogenesis of COPD, it is therefore, possible that therapeutic administration or supplementation of multiple antioxidants and/or boosting the endogenous levels of antioxidants will be beneficial in the treatment of COPD. This review discusses various novel pharmacological approaches adopted to enhance lung antioxidant levels, and various emerging beneficial and/or prophylactic effects of antioxidant therapeutics in halting or intervening the progression of COPD. This article is part of a Special Issue entitled: Antioxidants and Antioxidant Treatment in Disease.

The effects of modulators of cytochrome P450 and reduced glutathione (GSH) on the hepatotoxicity of enalapril maleate (EN) were investigated in Fischer 344 rats. Twenty-four hours following the administration of EN (1.5 to 1.8 g/kg), increased serum transaminases (ALT and AST) and hepatic necrosis were observed. Pretreatment of the animals with pregnenolone-16alpha-carbonitrile, a selective inducer of the cytochrome P450IIIA gene subfamily, enhanced EN-induced hepatotoxicity, whereas pretreatment with the cytochrome P450 inhibitor, cobalt protoporphyrin, reduced the liver injury. Depletion of hepatic non-protein sulfhydryls (NPSHs), an indicator of GSH, by combined treatment with buthionine sulfoximine (BSO) and diethyl maleate (DEM) produced marked elevations in serum transaminases by 6 hr after EN treatment. Administered on its own, EN decreased hepatic NPSH content and when combined with the BSO/DEM pretreatment, the liver was nearly completely devoid of NPSHs. Protection from EN-induced hepatotoxicity was observed in animals administered L-2-oxothiazolidine-4-carboxylic acid, a cysteine precursor. Together, these observations suggest the involvement of cytochrome P450 in EN bioactivation and GSH in detoxification. The results corroborate previous in vitro observations pertaining to the mechanism of EN-induced cytotoxicity towards primary cultures of rat hepatocytes. Although the doses of EN used in this study were far in excess of therapeutic doses, under certain circumstances, this metabolism-mediated toxicologic mechanism could form the basis for idiosyncratic liver injury in patients receiving EN therapy.

Twenty-four asymptomatic, HIV-1-seropositive subjects with CD4 cell counts of ?400/mul participated in a Phase I/II, dose escalation trial of intravenous L-2-oxothiazolidine-4-carboxylic acid (OTC: Procysteine). Four groups of six subjects each were consecutively assigned to receive OTC at an initial dose of 3, 10, 30, or 100 mg/kg, followed by the same dose given twice weekly for 6 weeks. Increases in whole-blood glutathione were observed in the highest dosage group after 6 weeks of therapy. No effects on changes in CD4 cell counts, viral load, or proviral DNA frequency were observed among the four dosage groups, although a decline in beta2-microglobulin levels was apparent in the highest dosage group. One subject withdrew due to headaches; other probable adverse events including rash, flushing, pruritus, lightheadedness, and diminished concentration were self-limited.
