Enhancement of biodegradation potential of catechol 1,2-dioxygenase through its immobilization in calcium alginate gel
Abstract Background In biodegradation processes free enzymes often undergo deactivation. Thus, it is very important to obtain highly stable enzymes by different methods. Immobilization allows for successful stabilization of many...

Glutathione Alleviates the Influence of N-Nitrosamines on the Activity of Carcinogen-Metabolizing Enzymes in the Liver of Male Mice
Abstract Most xenobiotics and carcinogens are metabolized primarily by the hepatic drug-metabolizing enzymes including cytochrome P450, cytochrome b5, arylhydrocarbon hydroxylase (AHH), and dimethylnitrosamine N-demethylase I (DMN-dI) as phase I...

Screening of diseases associated with abnormal metabolites for evaluation of HPLC in organic aciduria profiling
Abstract Background Organic acid disorders are a heterogeneous group of inborn errors of metabolism, in which organic acids accumulate in the body. They have high prevalence in Egypt because of a high rate of consanguineous...

Structural requirements of N-aryl-oxazolidinone-5-carboxamide derivatives for anti-HIV protease activity using molecular modelling techniques
Abstract Two- and three-dimensional quantitative structure–activity relation (QSAR) models were generated for a series of N-aryl-oxazolidinone-5-carboxamide derivatives to identify potent anti-HIV-1 integrase ligands. The studies were performed by...
