The study was aimed to prepare a co-amorphous system of valsartan (VAL) with vanillin (VAN) for improving its solubility and dissolution followed by its confinement in mesoporous silica particles (MSPs) to stabilise the co-amorphous system and prevent its recrystallization. Amorphous VAL and VAN were obtained through quench-cooling and VAL/VAN binary co-amorphous system (VAL/VAN-CAS) was prepared through solvent evaporation technique. The particle size and morphology of VAL/VAN-CAS-MSPs were studied using scanning electron microscopy (SEM) and solid-state characterisation was performed by differential scanning calorimetry (DSC) and X-ray powder diffraction (XRPD). The in vitro dissolution was investigated by dialysis bag diffusion method. SEM analysis revealed irregular shaped VAL/VAN-CAS-MSPs with a size range of 5–25?μm, while outcomes of DSC and XRPD confirmed the formation of VAL/VAN-CAS. The in vitro dissolution profiles demonstrated a significantly increased dissolution in first 60?minutes from VAL/VAN-CAS (~68%) and VAL/VAN-CAS-MSPs (~76%) compared to powder VAL (~25%). 相似文献

BackgroundAcetamiprid (ACMP) is a member of the neonicotinoid group of insecticides. It is extensively used worldwide. The misuse of ACMP creates danger hazards to human and animal.MethodsACMP induced renal damage evidenced by an increase in kidney injury biomarkers. So the goal of this work is to clarify the reno protective effect of Quercetin (Qrctn) and/or Nano-glutathione (N-Gluta) solely or in combination to counterbalance the danger effect of ACMP. All treatments with the previous agents were coadministered orally with ACMP for one month.ResultsACMP ingestion caused a significant rise in serum creatinin, urea, and uric acid, TNF α along with renal cystatin C, lipid peroxidation and nitric oxide with the concomitant decline in the levels of reduced glutathione and IL-10 levels. Protein expression of ICAM was upregulated as well as mRNA expression of NF-κB while mRNA expression of Nrf2 was down-regulated. Immune histochemistry of TLR 4 revealed strong immune reaction. The administration of Qrctn or N-Gluta either individually or together modulated all the preceding aforementioned parameters.ConclusionFascinatingly Qrctn and N-Gluta combination was the most powerful regimen to frustrate ACMP reno-toxicity and may be deliberate as a hopeful applicant for renal therapy. 相似文献

The hypocretin/orexin (Hcrt/orexin) unit affects the functions of the nervous, cardiovascular, gastrointestinal, and reproductive systems. Hcrt/orexin ligands and receptors have been localized to different parts of the central and peripheral nervous systems, cerebrospinal fluid and blood, exocrine (pancreas, salivary, lacrimal) as well as endocrine (pancreatic islets, pituitary, adrenal) glands. Several factors including stress, glucagon‐like peptide‐1 agonists, glutamate, nicotine, glucose, and hypoglycaemia stimulate the expression of Hcrt/orexin system, but it is inhibited by ageing, bone morphogenetic protein, hypoxia/hypercapnia, melanocortin receptor accessory protein 2, and glucagon. Literature reports show that Hcrt/orexin can significantly increase insulin secretion from normal and diabetic rat pancreata. Hcrt/orexin decreases blood glucose concentration and reduces insulin resistance partly via increased tissue expression of glucose transporter type 4. It reduces obesity by increasing browning of fat cells and energy expenditure. Taken together, Hcrt/orexin modulates obesity and the metabolism of glucose and insulin. The Hcrt/orexin system may thus be a target in the development of new therapies for the treatment of diabetes mellitus. 相似文献
