Salvianic acid A (Danshensu) is a major water-soluble component extracted from Salvia miltiorrhiza (Danshen), which has been widely used in clinic in China for treatment of cardiovascular diseases (CVDs). This study aimed to investigate the protective effects of salvianic acid A sodium (SAAS) ag...
Oxidative stress causes endothelial death while underlying mechanisms remain elusive. Herein, the pro-death effect of tert-butyl hydroperoxide (t-BHP) was investigated with low concentration (50 μM) of t-BHP (t-BHPL) and high concentration (500 μM) of t-BHP (t-BHPH). Both t-BHPL and t-BHPH ind...
Hypericum androsaemum L. (Guttiferae) is a medicinal plant with antioxidant activity. Increasing evidence regarding free radical generating agents suggests that hepatotoxic-related disorders may involve reactive oxygen species (ROS). The purpose of this study was to investigate the protective ef...
Oxidative stress plays an important role in neurodegenerative diseases. Reactive oxygen species (ROS)-mediated stress in microglia in vivo could result in cellular injuries and preferentially induces neuronal injury. Corilagin, a novel member of the phenolic tannin family, has been shown to poss...
The ruthenium catalyzed inversion of l-lactic acid esters in the presence of Novozym 435 is described which give d-lactates in good yields and with >99% ee.
We report the electroanalytical properties of an amperometric bioelectrode containing l-lactate oxidase (LOx) immobilized on glassy carbon electrode with a hydrogel film composed of laponite and different amounts of a novel bioinspired polycation obtained by copolymerization of 4-vinylbenzyl thy...
The fate of fuel oxygenates such as methyl tert-butyl ether (MTBE) in the subsurface is governed by their degradability under various redox conditions. The key intermediate in degradation of MTBE and ethyl tert-butyl ether (ETBE) is tert-butyl alcohol (TBA) which was often found as accumulating ...
The present study investigates the antioxidant and hepatoprotective effects of Capparis spinosa L. and Quercetin in tert-butyl hydroperoxide (t-BHP) induced acute liver damage. Different fractions of C. spinosa were examined for total phenolic content and antioxidant property. Among these fracti...
Gallic acid (GA), a natural polyphenol, has been shown to exert a variety of heath promoting effects. We herein investigated the critical role of nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated antioxidant response in the protection of GA against tert-butyl hydroperoxide (t-BHP)-indu...
Two siblings were evaluated for progressive proximal weakness and elevated creatine kinase. Immunohistochemical staining in the brother’s muscle biopsy showed near absence of all four sarcoglycan subunits. Clinical progression prompted a trial of deflazacort in both siblings. At 22 months of dr...
Toxic epidermal necrolysis (TEN) is a drug-related fatal disease. Extensive necrosis of the epidermis can lead to serious complications. This report describes two cases of TEN, associated with deflazacort (DFZ), in two boys, aged 4 years and 14 years, with nephrotic syndrome (NS). The 14-year-ol...
SummarySteroids are commonly used for the treatment of intractable epilepsy. Deflazacort has shown similar effects to prednisone, but with a less worrying adverse-effect profile. In this study, we first compared the efficacy, safety, and seizure relapse rate of deflazacort versus hydrocortisone ...
Duchenne muscular dystrophy (DMD) is a progressive and fatal disease, characterized by the absence of dystrophin, muscle degeneration and cardiorespiratory failure. Creatine kinase is the classic marker to screen for DMD. However, other markers are needed to follow disease progression and to eva...
ObjectivesGlucocorticoids are important and frequently used class of anti-inflammatory drugs. Deflazacort (DFZ) is a glucocorticoid and an oxazolone derivative of prednisolone. As it has high anti-inflammatory and immunosuppressive potency, we studied inhibitory effect of DFZ on mediators regula...
Forced Degradation of Deflazacort drug substance in ultraviolet light condition resulted into a number of significant degradation products. Two of these degradation products were found to be unknown during the study and marked as DD-I and DD-II. Thus, the objective of this work is to investigate...
Deflazacort is a glucocorticoid used for the treatment of inflammatory and allergic disorders …
The solubility of Deflazacort in four solvents, acetone, ethyl acetate, ethanol and 2-propanol, was measured at temperatures ranging from 293.15 K to 348.15 K at atmospheric pressure using Laser Monitoring Technique. The solubility data were correlated by the modified Apelblat model. Then the di...
BackgroundThe routine use of glucocorticoids has increased the longevity of patients with Duchenne muscular dystrophy. Long-term steroid therapy may have adverse effects on endocrine function and could influence the onset of puberty.
Deflazacort (DFC) is a heterocyclic glucocorticoid with anti-inflammatory activity but with decreased side effects. In this study, we have evaluated the capacity of DFC and other glucocorticoids to reach the central nervous system (CNS) in vivo by measuring changes of [3H]dexamethasone (DEX) bin...
Deflazacort, a new steroidal anti-inflammatory agent, has remarkable glucocorticoid activity in both animals, and humans. Its biologically active form, 21-desacetyl deflazacort, displaces [3H]dexamethasone from its cytosol receptor sites in rat kidney, thymus and liver in vitro. Although less ac...
