Repurposing azole antifungals into antileishmanials: Novel 3-triazolylflavanones with promising in vitro antileishmanial activity against Leishmania major.

Previously, we have described a series of azole antifungals namely 3-(1,2,4-triazol-1-yl)flavanones (TFs) containing an N-(phenethyl)azole framework required for sterol 14α-demethylase (CYP51) inhibitory activity. Similar mechanism of action of azoles in fungi and protozoan parasites prompted us to investigate the potential effects of TFs against promastigote and amastigote forms of Leishmania major (L. major), as well as their toxicity against macrophages, apoptosis induction and in silico interactions with the target enzyme.

Electrosprayed Nanosystems of Carbamazepine - PVP K30 for Enhancing Its Pharmacologic Effects.

This study was conducted to enhance the pharmacologic effect of carbamazepine (CBZ) (as a poorly water-soluble drug) by fabricating CBZ-PVP K30 nanobeads using an electrospraying technique. CBZ-PVP K30 nanosystems with various ratios (1:3 and 1:5) at total solution concentrations of 3% and 5% w/v were prepared. The solution concentration extremely affected the size of the samples; where, the nanobeads (mean diameter of 457.

Synthesis and biological evaluation of new N-benzylpyridinium-based benzoheterocycles as potential anti-Alzheimer's agents.

A novel series of benzylpyridinium-based benzoheterocycles (benzimidazole, benzoxazole or benzothiazole) were designed as potent acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. The title compounds 4a-q were conveniently synthesized via condensation reaction of 1,2-phenylenediamine, 2-aminophenol or 2-aminothiophenol with pyridin-4-carbalehyde, followed by N-benzylation using various benzyl halides. The results of in vitro biological assays revealed that most of them, especially 4c and 4g, had potent anticholinesterase activity comparable or more potent than reference drug, donepezil.

PC12 cells pretreated with saffron extract (2.

Recent advances in improving oral drug bioavailability by cocrystals.

: Oral drug delivery is the most favored route of drug administration. However, poor oral bioavailability is one of the leading reasons for insufficient clinical efficacy. Improving oral absorption of drugs with low water solubility and/or low intestinal membrane permeability is an active field of research.

Association of modified Nordic diet with cardiovascular risk factors among type 2 diabetes patients: a cross-sectional study.

Cardiovascular disease (CVD) is one of the most important causes of mortality. Healthy diets can decrease CVDs and other chronic diseases especially in patients with type 2 diabetes. In this study, we investigate association between adherence to the modified Nordic diet and cardiovascular risk factors among patients with type 2 diabetes.

Permeability and Line-Tension-Dependent Response of Polyunsaturated Membranes to Osmotic Stresses.

The lipidome of plant plasma membranes-enriched in cellular phospholipids containing at least one polyunsaturated fatty acid tail and a variety of phytosterols and phytosphingolipids-is adapted to significant abiotic stresses. But how mesoscale membrane properties of these membranes such as permeability and deformability, which arise from their unique molecular compositions and corresponding lateral organization, facilitate response to global mechanical stresses is largely unknown. Here, using giant vesicles reconstituting mixtures of polyunsaturated lipids (soy phosphatidylcholine), glucosylceramide, and sitosterol common to plant membranes, we find that the membranes adopt "janus-like" domain morphologies and display anomalous solute permeabilities.

Construction and functional characterization of a fully human anti-CD19 chimeric antigen receptor (huCAR)-expressing primary human T cells.

Although remarkable results have been attained by adoptively transferring T cells expressing fully murine and/or humanized anti-CD19 chimeric antigen receptors (CARs) to treat B cell malignancies, evidence of human anti-mouse immune responses against CARs provides a rationale for the development of less immunogenic CARs. By developing a fully human CAR (huCAR), these human anti-mouse immune responses are likely eliminated. This, perhaps, not only increases the persistence of anti-CD19 CAR T cells-thereby reducing the risk of tumor relapse-but also facilitates administration of multiple, temporally separated doses of CAR T cells to the same recipient.

Phytochemistry, Traditional Uses and Pharmacological Profile of Rose Hip: A Review.

Background: The fruit of genus Rosa, known as "rose hip", is frequently used in different traditional medicines. Rose hips have long been used to treat kidney stones, gastroenteric ailments, hypertension and respiratory problems such as bronchitis, cough and cold.

Aim: This review is focused on the ethnopharmacological uses of rose hip as well as phytochemical and pharmacological aspects.

Dabigatran as a Treatment Option for Heparin-Induced Thrombocytopenia.

Heparin-induced thrombocytopenia (HIT) is a potentially serious adverse drug reaction that can result in lethal vascular thrombosis. Dabigatran is a direct thrombin inhibitor that might be useful in the management of HIT. This study evaluated the efficacy and safety of dabigatran in patients with HIT.

Ultrastructural Investigation of Promastigotes Treated with A New Potent Antileishmanial Azole Using Scanning Electron and Atomic Force Microscopes.

Aim And Background: Azoles as antifungal drugs have been used to treat leishmaniasis for many years. Several evidences suggesting that the primary target of azoles is the heme protein, which co-catalyzes cytochrome P-450-dependent 14α-demethylation of lanosterol. Little is known about the structural changes caused by azoles with atomic force microscopy (AFM) or scanning electron microscopy (SEM).

Albumin Utilization Evaluation in a Major Teaching Hospital in Iran: Recommendations for Guideline Development.

Objective: Human albumin solution is an expensive colloidal preparation which is commonly used in clinical practice. Due to high cost of albumin, increased rate of the inappropriate use worldwide, and many other reasons, it is imperative to establish a practical protocol to use albumin products and limit its usage. The aim of this study was to identify albumin utilization patterns in a teaching hospital and to demonstrate the importance of the need to reconsider prescribing strategies for albumin administration.

Hearing Performance in the Follicular-Luteal Phase of the Menstrual Cycle.

Introduction: Estrogen has a protective role on auditory function. It may have an excitatory action on auditory nerve fibers and can have a neuroprotective effect. Progesterone has a mainly inhibitory action on the central nervous system, which may balance the mainly excitatory action of estrogen.

Vγ9Vδ2 T cells proliferate in response to phosphoantigens released from erythrocytes infected with asexual and gametocyte stage Plasmodium falciparum.

Vγ9Vδ2 T cells, the dominant γδ T cell subset in human peripheral blood, are stimulated by phosphoantigens, of which (E)-4-Hydroxy-3-methyl-but-2-enyl pyrophosphate, is produced in the apicoplast of malaria parasites. Cell-free media from synchronised Plasmodium falciparum asexual ring, trophozoite, and schizont stage-cultures of high purity as well as media from ruptured schizont cultures, all stimulated Vγ9Vδ2 T cell proliferation, as did media from pure gametocyte cultures, whereas media from uninfected erythrocytes cultures did not. The media from ruptured schizont cultures and all the asexual and gametocyte stage cultures contained only background iron levels, suggesting that all erythrocyte haemoglobin is consumed as the parasites develop and supporting that the phosphoantigens were released from intact parasitized erythrocytes.

Acetophenone benzoylhydrazones as antioxidant agents: Synthesis, in vitro evaluation and structure-activity relationship studies.

Acetophenone and its analogues are naturally-occurring compounds found in many foods and plants. In this study, a series of acetophenone benzoylhydrazones 5a-o were designed and synthesized as new potential antioxidant agents. Designed molecules contain hydrazone and phenolic hydroxyl moieties which possibly contribute to antioxidant activity.

Intersection of phosphate transport, oxidative stress and TOR signalling in Candida albicans virulence.

Phosphate is an essential macronutrient required for cell growth and division. Pho84 is the major high-affinity cell-surface phosphate importer of Saccharomyces cerevisiae and a crucial element in the phosphate homeostatic system of this model yeast. We found that loss of Candida albicans Pho84 attenuated virulence in Drosophila and murine oropharyngeal and disseminated models of invasive infection, and conferred hypersensitivity to neutrophil killing.
