Folate-conjugated Pluronic F87-poly(lactic-co-glycolic acid) block copolymer (FA-F87-PLGA) was synthesized to encapsulate anticancer drug Paclitaxel (PTX) for targeted drug delivery. To further improve the curative effect, D-α-tocopheryl poly(ethylene glycol) 1000 succinate (TPGS or Vitamin E TPGS) was added to form FA-F87-PLGA/TPGS mixed NPs.

FA-F87-PLGA was synthesized by the ring-opening polymerization and the structure was characterized. selleck chemicals PTX-loaded nanoparticles were prepared with the nanoprecipitation method. The physicochemical characteristics were studied to determine the appropriate dose ratio of the FA-F87-PLGA to TPGS. The cytotoxicity against Ovarian Cancer Cells (OVCAR-3) was determined by MTT assay. The Area-Under-the Curve (AUC) and half-life were measured in the vivo pharmacokinetic studies.

Based on the optimization of particle size and embedding rate of PTX-loaded mixed NPs, the appropriate dosage ratio of FA-F87-PLGA to TPGS was finally determined to be 53. According to in vitro release studies, the cumulative release rate of PTX-loaded FA-F87-PLGA/TPGS mixed NPs was 92.04%, which was higher than that of nanoparticles without TPGS. The cytotoxicity studies showed that the IC50 value of PTX-loaded FA-F87-PLGA/TPGS decreased by 75.4 times and 19.7 times after 72 h treatment compared with free PTX injections and PTX-loaded FA-F87-PLGA NPs, respectively. In vivo pharmacokinetic studies indicated that FA-F87-PLGA/TPGS mixed NPs had a longer drug metabolism time and a larger Area-Under-the-Curve (AUC) compared with free PTX injections.

FA-F87-PLGA/TPGS mixed NPs are potential candidates for targeted drug delivery systems.

NO is a gaseous substance with a short half-life in the body and is unstable in aqueous solutions. Therefore, many researchers focus on the release and activity of NO donors and their derivatives. However, NO donors can release free NO or NO analogues under physiological conditions to meet the human need. NO donors can be coupled with the corresponding active basic nucleus, so that they have the biological activity derived from both the basic nucleus and the NO donors, thus performing better bioactivity. This paper reviewed the routes of synthesis and advance activities of NO donor derivatives.Coronavirus disease (CoVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) scrambles the world by infecting millions of peoples all over the globe. It has caused tremendous morbidity, mortality and greatly impacted the lives and economy worldwide as an outcome of mandatory quarantines or isolations. Despite the worsening trends of COVID-19, no drugs are validated to have significant efficacy in clinical treatment of COVID-19 patients in large-scale studies. Physicians and researchers throughout the world are working to understand the pathophysiology to expose the conceivable handling regimens and to determine the effective vaccines and/or therapeutic agents. Some of them re-purposed drugs for clinical trials which were primarily known to be effective against the RNA viruses including MERS-CoV and SARS-CoV-1. In the absence of a proven efficacy therapy, the current management use therapies based on antivirals, anti-inflammatory drugs, convalescent plasma, anti-parasitic agents in both oral and parenteral formulation, oxygen therapy and heparin support. What is needed at this hour, however, is a definitive drug therapy or vaccine. Different countries are rushing to find this, and various trials are already underway. We aimed to summarized the potential therapeutic strategies as a treatment options for COVID-19 that could be helpful to stop further spread of SARS-CoV-2 by effecting its structural components or modulation of immune response and also discusses the leading drugs/vaccines, which were considered as potential agents for controlling this pandemic.
Chagas disease is a potentially life-threatening illness caused by the protozoan parasite Trypanosoma cruzi and is transmitted to humans through the excreta of infected blood-sucking triatomine bugs. According to the World Health Organization, 6 to 7 million people are infected with T. cruzi worldwide, mainly in Latin America with more than 10000 deaths annually.

The present study aims to provide comprehensive literature information on the importance of triazole-containing heterocycles in the development of anti-Chagas disease agents.

The embodied information was acquired without date limitation by December 2020 using various electronic databases including, SciFinder, PubMed (National Library of Medicine), Science Direct, Wiley, ACS (American Chemical Society), SciELO (Scientific Electronic Library Online), Google Scholar, Springer, Scopus, and Web of Science.

Upon in vitro studies, more than 100 triazole-containing heterocycles have been predicted as active compounds against the pathogen responsible nce of triazole-containing heterocycles in search of potential candidates for drug development against Chagas disease. Nonetheless, the use of new catalysts and chemical transformations is expected to provide avenues for the synthesis of unexplored triazole derivatives, leading to the development of triazole-containing compounds with new properties and trypanocidal activity.
Molecular therapy with sorafenib remains the mainstay for advanced-stage hepatocellular carcinoma. Notwithstanding, treatment efficacy is low, with few patients obtaining long-lasting benefits due to the high chemoresistance rate.

To perform, for the first time, an overview of the literature concerning the role of adenosine triphosphate-binding cassette (ABC) transporters in sorafenib therapy for hepatocellular carcinoma.

Three online databases (PubMed, Web of Science and Scopus) were searched, from inception to October 2020. Studies selection, analysis and data collection was independently performed by two authors.

The search yielded 224 results; 29 were selected for inclusion. Most studies were pre-clinical, using HCC cell lines; three used human samples. Studies highlight the effect of sorafenib in decreasing ABC transporters expression. Conversely, it is described the role of ABC transporters, particularly multidrug resistance protein 1 (MDR-1), multidrug resistance-associated proteins 1 and 2 (MRP-1 and MRP-2) and ABC subfamily G member 2 (ABCG2) in sorafenib pharmacokinetics and pharmacodynamics, being key resistance factors. Combination therapy with naturally available or synthetic compounds that modulate ABC transporters may revert sorafenib resistance, by increasing absorption and intracellular concentration.

A deeper understanding of ABC transporters' mechanisms may provide guidance for developing innovative approaches for hepatocellular carcinoma. Further studies are warranted to translate the current knowledge into practice and paving the way to individualized therapy.

This disease can be associated with several manifestation like red flaks, silver scale, patches, plaques and silvery-white squams. Approximately 70% of the patients treated with topical dosage forms have a mild-to-moderate form of psoriasis, whereas a moderate-to-severe form of psoriasis is treated with systemic, photo, and biological therapies. Considering the big fraction that topicals cover, we present the current market potential, clinical relevance, and recent advances in the topical delivery of the drug for psoriasis. Though we witnessed several advancements in the recent few decades, delivering new immunomodulatory and biological molecules for topical psoriatic treatment have been proved efficient and safe option for the large percentage of patients for whom systemic therapy is not indicated. This article enumerates the promising topical dosage forms at present under assessment for their clinical pertinence. The competency of conventional topicals to reach and transform the world market is enumerated in terms of their success rate after proving the clinical pertinence against psoriasis. However, the entrance of novel drug delivery systems based advanced topical products in the global market is highly anticipated as they have immense potential to precedent tremendous impact on psoriasis treatment in near future.Gut microbiota is a complex microecosystem which is called the second genome of the human body. Herbal medicine can balance tumor-suppressing bacteria and tumor-promoting bacteria and exert its anti-cancer effect by regulating gut microbiota. Traditional Chinese medicine (TCM) has a history of thousands of years in prevention and treatment of diseases in China. In recent decades, TCM show an obvious advantage in prolonging the survival time and improving the living quality of patients with cancer. Notably, gut microbiota has become a new pathway to understanding TCM. In this review, we will focus on gut microbiota and tumor progression, especially the diversity, functionality and metabolites of gut microbiota affected by TCM in various cancer. We will also discuss the potential mechanism of gut microbiota for exploring TCM in anti-cancer effect. This article aims to comprehensively review the anti-cancer research of TCM by regulating gut microbiota, and address future perspectives and challenges of gut microbiota in TCM intervention for cancer.The Mediterranean diet is appraised as the premier dietary regimen and its espousal is correlated with the prevention of degenerative diseases and extended longevity. The consumption of olive oil stands out as the most peculiar feature of the Mediterranean diet. Olive oil rich in various bioactive compounds like oleanolic acid, oleuropein, oleocanthal, and hydroxytyrosol is known for its anti-inflammatory as well as cardioprotective property. Recently in silico studies have indicated that phytochemicals present in olive oil are a potential candidate to act against SARS-CoV-2. Although extensive studies on olive oil and its phytochemical composition; still, some lacunas persist in understanding how the phytochemical composition of olive oil is dependent on upstream processing. The signaling pathways regulated by olive oil in the restriction of various diseases is also not clear. To answer these queries, a detailed search of research and review articles published between 1990 to 2019 were reviewed in this effecoV-2.Exposure to environmental toxicants such as Arsenic (As) can result in As-induced alterations in immune regulators. Consequently, people who are more prone to viral infections like influenza A or B, H1N1, SARS CoV (Severe Acute Respiratory Syndrome Coronavirus), and SARS CoV2 may develop susceptibility to immune responses in their lungs because our previous reports delineated the ability of QIAPI 1®, a melanin precursor, to dissociate water molecules with simultaneous therapeutic efficacy against central nervous system (CNS) diseases, retinopathy, and As-induced renal toxicity. Given the commonalities of lung pathology of SARS CoV and As-induced toxicity, the aim of this study is to decipher the efficacy of QIAPI 1® against pentavalent As-induced lung toxicity by examining the pulmonary pathology. Hematoxylin & Eosin (H&E) staining was used for ascertaining the lung pathology in Wistar rat models. Animals were divided into 3 groups control group, group treated with pentavalent As, and a group treated with pentavalent As and QIAPI 1®.
