Diabetes mellitus is a serious global health issue, currently affecting 425 million people and set to affect over 690 million people by 2045. It is a chronic disease characterized by hyperglycemia due to relative or absolute insulin hormone deficiency. Dipeptidyl peptidase-IV (DPP-IV) inhibitors are hypoglycemic agents augmenting the action of the incretin hormones that stimulate insulin secretion from the pancreatic beta cells.
In this study synthesis and biological evaluation of seven piperazine derivatives 3a-g was carried out.
The synthesized molecules were characterized using proton-nuclear magnetic resonance, carbon- nuclear magnetic resonance, infrared spectroscopy and mass spectrometry.
In vitro biological evaluation study showed comparable DPP-IV inhibitory activity for the targeted compounds ranging from 19%-30% at 100 µM concentration. Furthermore, the in vivo hypoglycemic activity of 3d was evaluated using streptozotocin-induced diabetic mice. It was found that compound 3d significantly decreased the blood glucose level when comparing the diabetic group treated with 3d to the control diabetic group. Quantum-Polarized Ligand Docking (QPLD) studies demonstrate that 3a-g fit the binding site of DPP-IV enzyme and form H-bonding with the backbones of R125, E205, E206, K554, W629, Y631, Y662, R669, and Y752.
Piperazine derivatives were found to be successful new scaffold as potential DPP-IV inhibitors.

DMP shows several merits over other common oxidative agents such as chromiumand DMSO-based oxidants; thus, it is habitually employed in the total synthesis of natural products. In this review, we try to underscore the applications of DMP as an effective oxidant in an appropriate step (steps) in the multi-step total synthesis of natural products.
Tenofovir (TDF) has a detrimental effect on bone mineral density (BMD), while nonalcoholic fatty liver disease (NAFLD) is associated with a lower BMD.
To help understand the mutual effects of NAFLD and TDF on BMD, this study was designed to explore the potential association between NAFLD and BMD in HIV-infected patients receiving long-term TDF-based antiretroviral therapy (ART).
A total of 89 HIV-infected patients who received TDF-based ART for more than three years were enrolled in this cross-sectional study. We measured BMD using an ultrasonic bone density apparatus, and liver ultrasonography was performed to determine the severity of the fatty liver. The association of NAFLD with BMD was examined using multiple logistic regression analyses.
Patients with NAFLD showed a worse BMD status than those without NAFLD. The incidence rates of osteopenia (42.86% versus 25.93%) and osteoporosis (17.14% versus 3.70%) were significantly higher in HIV-infected patients with NAFLD than in those without NAFLD. After multivariate adjustment, the odds ratio (OR) for patients with NAFLD exhibiting a worse BMD status compared with those without NAFLD was 4.49 (95% confidence interval [CI] 1.42, 14.15).
Based on our results, NAFLD was significantly associated with a worse BMD status, including osteopenia and osteoporosis, in HIV patients after receiving long-term TDF-based ART. Furthermore, we may want to avoid using TDF for ART in HIV-infected patients with NAFLD.

Native nAChRs, activated by acetylcholine (ACh) endogenously, are involved in a variety of physiological and pathophysiological processes. They regulate processes necessary for network operations through neurotransmitter release, cell excitability and neuronal integration. Emerging evidence suggests that nAChRs are capable of regulating cardiovascular (CV) functions in a cell type-specific manner, through the nervous system and non-neuronal tissues. The aim of this review is to describe the most recent findings regarding the role of nAChRs inside and outside the nervous system in the regulation of CV activities.
The purpose of this study is to develop a new PLGA based formulation for microspheres, which aims to release mometasone furoate for one month, so as to improve compliance.
The microspheres containing mometasone furoate were prepared by oil in water emulsion and solvent evaporation. The microspheres were characterized by surface morphology, shape, size and encapsulation efficiency. The release in vitro was studied in 37°C phosphate buffer, and in vivo, pharmacodynamics and preliminary safety evaluation were conducted in male Sprague Dawley rats.
The morphology results show that the microspheres have smooth surface, spherical shape and the average diameter of 2.320-5.679μm. The encapsulation efficiency of the microspheres loaded with mometasone furoate is in the range of 53.1% to 95.2%, and the encapsulation efficiency of the microspheres can be greatly affected by the proportion of oil phase to water phase and other formulation parameters. In vitro release kinetics revealed that drug release from microspheres was through non Fick's diffusion and PLGA polymer erosion. Pharmacokinetic data showed that the initial release of microspheres was small and then sustained. The results of pharmacodynamic study fully proved the effectiveness and long-term effect of mometasone furoate microspheres. The results of in vivo safety evaluation showed that the preparation system had good in vivo safety.
This study shows that the microspheres prepared in this study have sufficient ability of stable drug release at least 35 days, with good efficacy and high safety. In addition, mometasone furoate can be used as a potential candidate drug for 35 day long-term injection.

Until today, the best solution for the moment remains prevention (Social distancing, hand disinfection, use of masks, partial or total sanitary containment, etc.), there is also the emergence of drug treatment (research and development, clinical trials, use on patients). Recent reviews emphasized the role of membrane lipids in the infectivity mechanism of SARS-COV-2. link3 Cholesterol-rich parts of cell membranes serve as docking places of host cells for the viruses. selleck chemical is a member of a virus family with lipid envelope that fuses with host cell through endocytosis, internalizing its components in the cell. In vitro cell models have shown that depletion of cholesterol by cyclodextrin, and particularly methyl beta cyclodextrin disturb the host cell membrane lipid composition this way reducing the attachment of the virus to the protein receptors. This review aims to summarize the state of the art of research concerning the use of cyclodextrin or its complexes as a potential treatment against this new virus and update work already published.
Bioconjugations are swiftly progressing and are being applied to solve several limitations of conventional drug delivery systems (DDS) such as lack of water solubility, non-specific, and poor bioavailability. The main goals of DDS are to achieve greater drug effectiveness and minimize toxicity to the healthy tissues.
In this study, D-glucose was conjugated with eugenol to target the cancer cells. To identify the implication of the anticancer effect, osteosarcoma (K7M2) cells were cultured and the anti-proliferative effect was performed using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay] test in order to evaluate the viability and toxicity on cells with various concentrations of eugenol and D-glucose-eugenol conjugate in 24-hour incubation.
It was found that, the successful confirmation of the conjugation between D-glucose and eugenol was obtained by 1 H NMR spectroscopy. MTT assay showed inhibitory concentration (IC50 value) of D-glucose-eugenol was at 96.2 µg/ml and the decreased of osteosarcoma cell survival was 48%.
These findings strongly indicate that K7M2 cells would be affected by toxicity of D-glucose-eugenol. Therefore, the present study suggests that D-glucose-eugenol has high potential to act as an anti-proliferative agent who may promise a new modality or approach as the drug delivery treatment for cancer or chemotherapeutic agent.

Development of controlled drug delivery systems can improve the pharmacokinetic characteristics of drug molecules in the human body, thereby significantly improving the utilization rate of drugs and reducing toxicity and side effects caused by high concentrations of drugs, which can occur when delivery is not controlled. Metal organic frameworks are a new class of very promising crystalline microporous materials, especially when the size is reduced to the nanometer range. Metal organic frameworks exhibit large specific surface areas, tunable compositions, and easy functionalization. In recent years, increasing number of studies have reported the remarkable advances in multifunctional nanoscale metal organic frameworks in drug delivery.
Review the latest research involving advances in stimuli-responsive nanoscale metal organic frameworks as drug delivery systems in controlled-release drugs.
We first introduce the two main strategies associated with nanoscale metal organic frameworks used in drug loading direct assembly and post-encapsulation.
