Pharmaceutical Properties

Uricase (urate oxidase EC 1.7.3.3, UC) catalyses the oxidation of uric acid, a final product of purine catabolism to allantoin. In the present work, Uricase is bioconjugated using PEG (Polyethylene glycol) as a chemical tool for linking for obtaining conjugates with better and desirable pharmaceutical properties. Uricase from Bacillus fastidisous (Uc) was modified through PEGylation considering various concentrations of linear polyethyleneglycol-8KDa (PEG-8K). The Uc-PEG 8K conjugates, formed by conjugating Uc and PEG-8K in the ratio of 1:15 retained 87.5% of the initial uricolytic activity, and were highly stable at pH 6.0, which is quiet close to physiological pH and at a temperature of 16°C.

We examined the influence ofl-carnitine l-tartrate (LCLT) on markers of purine catabolism, free radical formation, and muscle tissue disruption after squat exercise. With the use of a balanced, crossover design (1 wk washout), 10 resistance-trained men consumed a placebo or LCLT supplement (2 g l-carnitine/day) for 3 wk before obtaining blood samples on six consecutive days (D1 to D6). Blood was also sampled before and after a squat protocol (5 sets, 15–20 repetitions) on D2. Muscle tissue disruption at the midthigh was assessed using magnetic resonance imaging (MRI) before exercise and on D3 and D6. Exercise-induced increases in plasma markers of purine catabolism (hypoxanthine, xanthine oxidase, and serum uric acid) and circulating cytosolic proteins (myoglobin, fatty acid-binding protein, and creatine kinase) were significantly ( P ≤ 0.05) attenuated by LCLT. Exercise-induced increases in plasma malondialdehyde returned to resting values sooner during LCLT compared with placebo. The amount of muscle disruption from MRI scans during LCLT was 41–45% of the placebo area. These data indicate that LCLT supplementation is effective in assisting recovery from high-repetition squat exercise.
