A novel sensitive and high throughput chiral hydrophilic interaction chromatographic (HILIC) method was developed to separate razoxane enantiomers namely levrazoxane (R-isomer) and dexrazoxane (DEX) in pharmaceutical active ingredient samples. A systematic chiral chromatographic screening system was employed in using multiple HPLC chromatographic modes on various polysaccharide based chiral columns to obtain a potential separation between enantiomers. HPLC separation was achieved using a mobile phase of aqueous 10 mM ammonium bicarbonate and mixture of organic modifiers (70/30, v/v) in the ratio of (5/95, v/v) on an immobilized polysaccharide based chiral stationary phase namely CHIRALPAK IE-3...

Reducing early nonbacterial inflammation induced by implanted materials and infection resulting from bacterial contamination around the implant-abutment interface could greatly accelerate implant osseointegration and reduce implant failure, which would be of clinical significance. In this study, we developed a facile and versatile strategy for the construction of anti-inflammatory and antibacterial surfaces on implants, such as orthopedic/dental implants. Briefly, the surfaces of polystyrene (PS) culture plates were first coated with polydopamine and then decorated with dexamethasone plus minocycline-loaded liposomes (Dex/Mino liposomes), which was confirmed by contact angle goniometry, X-ray photoelectron spectroscopy, and fluorescence microscopy...

The retina contains the highest concentration of zinc in the human eye and it is primarily associated with the retinal pigment epithelium (RPE). Metallothioneins (MTs) are the main cytosolic zinc-ion-binding proteins, exerting a tight control in the number of atoms of Zn-bound to the MTs related with their antioxidant and neuroprotective functions. In order to study the Zn-MT system in retina and RPE, we have implemented mass spectrometry (MS)-based technologies: two complementary element detection methodologies (HPLC- and laser ablation (LA)-ICP-MS) have been successfully employed to study metal content in the human eye as well as to perform speciation studies of Zn-MTs...

Dexamethasone (Dex) is one of the essential medicines used to treat inflammation diseases but an overdose of Dex leads to severe adverse effects. The development of a new strategy to boost the anti-inflammation efficacy of Dex is, therefore, important but remains challenging. Herein, by employing an enzyme-instructed self-assembly system, we developed an intracellular coassembly strategy to boost the anti-inflammation efficacy of Dex. Under the catalysis of alkaline phosphatase (ALP), the hydrogelator precursor Nap-Phe-Phe-Tyr(H2PO3)-OH (1p) self-assembled to form Gel 1 but dexamethasone sodium phosphate (Dp) only yielded Dex precipitates...

This review presents the most relevant investigations concerning the biocatalytic kinetic resolution of racemic ketoprofen to dexketoprofen for the last 22 years. The advantages related to the administration of the dex-enantiomer in terms of human health, the so called "chiral switch" in the pharmaceutical industry and the sustainability of biotransformations have been the driving forces to develop innovative technology to obtain dexketoprofen. In particular, the kinetic resolution of racemic ketoprofen through enantiomeric esterification and hydrolysis using lipases as biocatalysts are thoroughly revised and commented upon...

Prolonged administration of an excessive dose of corticosteroids proved to be harmful for patients with acute lung injury (ALI). A previous study has found that repeated administration of an excessive dose of methylprednisolone reduced alveolar macrophages (AMs) in bronchoalveolar lavage fluid (BALF) with an unknown mechanism. This study aimed to investigate the effect of excessive use of dexamethasone (Dex) on BALF AMs in vitro. Transmission electron microscopy and DNA fragmentation analysis demonstrated that 10(-4) and 10(-5) M Dex induced lipopolysaccharide-stimulated rat AMs apoptosis with downregulation of tumor necrosis factor-α, interleukin (IL)-12 and upregulation of IL-10, transforming growth factor-β...

There is a growing recognition that glucocorticoid (GC) acts as an internal timing signal for peripheral circadian oscillators. However, the transcription process of GC-related clock gene in the peripheral tissues is not fully understood. The present study was designed to explore the potential role of clock genes in the GC-induced peripheral circadian gene expression invivo. Real-time RT-PCR analysis indicated that the transcript levels of Per1 and Dec1 were rapidly up-regulated within 0.5 and 1 h in the heart and kidney respectively after stimulation with dexamethasone (Dex)...

Dexamethasone (DEX) is the substrate of CYP3A. However, the activity of CYP3A could be induced by DEX when DEX was persistently administered, resulting in auto-induction and time-dependent pharmacokinetics (pharmacokinetics with time-dependent clearance) of DEX. In this study we investigated the pharmacokinetic profiles of DEX after single or multiple doses in human breast cancer xenograft nude mice and established a semi-mechanism-based pharmacokinetic/pharmacodynamic (PK/PD) model for characterizing the time-dependent PK of DEX as well as its anti-cancer effect...

Background: Abiraterone acetate is an androgen synthesis inhibitor approved for the treatment of castration-resistant prostate cancer (CRPC). Although co-administration of either prednisone or prednisolone at 10 mg/d has been recommended to reduce the risk of abiraterone-induced hyperaldosteronism (notably hypokalemia) and to give adjunctive pain relief effects, whether these glucocorticoids can be substituted by dexamethasone remains unknown. Methods: We performed a retrospective review of medical records of patients who were given abiraterone for the treatment of CRPC with either prednisolone (ABI/PSL) 10 mg/d or dexamethasone (ABI/DEX) 0...

Primary open angle glaucoma is an important type of glaucoma as it is one of the most common causes of blindness. Previous studies have demonstrated that in glaucomatous patients, the human trabecular meshwork (HTM) is markedly stiffened. The purpose of the present study was to determine the regulatory role of Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) in HTM cells. Primary HTM cells were cultured with different concentrations of dexamethasone (DEX), and the expression levels of YAP and TAZ were evaluated using reverse transcription-quantitative polymerase chain reaction and western blotting...

Corticosteroids, such as dexamethasone (DEX), are the mainstays for the treatment of moderate to severe inflammatory bowel disease (IBD). However, their relatively poor bioavailability and lack of specificity is often the origin of short and long-term adverse effects. Here, spherical polymeric nanoconstructs (SPNs) encapsulating dexamethasone are proposed for the systemic treatment of IBD. In a mouse model of colitis, the accumulation of SPNs within the inflamed intestine is firstly assessed using near infra-red fluorescent (NIRF) imaging at different stages of the disease - 5, 7 and 10 days of Dextran Sulfate Sodium (DSS) administration...

There is growing interest in the use of tolerogenic dendritic cells (tolDCs) as a potential target for immunotherapy. However, the molecular bases that drive the differentiation of monocyte-derived DCs (moDCs) toward a tolerogenic state are still poorly understood. Here, we studied the transcriptional profile of moDCs from healthy subjects, modulated with dexamethasone (Dex) and activated with monophosphoryl lipid A (MPLA), referred to as Dex-modulated and MPLA-activated DCs (DM-DCs), as an approach to identify molecular regulators and pathways associated with the induction of tolerogenic properties in tolDCs...
