As a member of the Convolvulaceae family, Convolvulus oxyphyllus is used in many medicinal contexts. The purpose of this study was to investigate the biological potency of plant methanolic extracts and determine the main bioactive components that give them their potencies. Using in vitro biological tests, the effects of plant extracts on cytotoxicity, antioxidant, and antibacterial activity were investigated.

Article Synopsis
  • - Tamarix tetragyna, a plant found in the Mediterranean and some Arab regions, has several medicinal properties, which this study aims to investigate through its leaf and stem extracts.
  • - The study analyzed the phytochemical composition using gas chromatography-mass spectrometry and tested the extracts' cytotoxicity against cancer cell lines (MCF-7, HepG-2, HCT-116, and A-549) using the MTT assay and apoptosis methods.
  • - Results showed that the plant extracts exhibited significant cytotoxic activity, especially against A-549 cells, with specific bioactive compounds identified that could lead to further research for potential anticancer therapies.

Influenza poses a significant threat to global health, with the ability to cause severe epidemics and pandemics. The polymerase basic protein 2 (PB2) of the influenza virus plays a crucial role in the viral replication process, making the CAP-binding domain of PB2 an attractive target for antiviral drug development. This study aimed to identify and evaluate potential inhibitors of the influenza polymerase PB2 CAP-binding domain using computational drug discovery methods.

Article Synopsis
  • Hepatitis C Virus (HCV) poses a major health threat globally, often leading to severe liver diseases like cirrhosis, due to its rapidly changing genome driven by NS5B polymerase.
  • This study investigates marine bacteria-derived compounds that can potentially inhibit the HCV NS5B polymerase through virtual screening, focusing on their binding affinity and stability.
  • Four compounds emerged as top candidates after extensive analysis, and their strong binding to NS5B shows promise for further experimental testing as potential treatments against HCV.

The increasing spread of the Monkeypox virus (MPXV) presents a significant public health challenge, emphasising the urgent requirement for effective treatments. Our study focuses on the VP39 Methyltransferase enzyme of MPXV as a critical target for therapy. By utilising virtual screening, we investigated natural compounds with structural similarities to sinefungin, a broad-acting MTase inhibitor.

Diabetic cardiomyopathy, a multifaceted complication of diabetes mellitus, remains a major challenge in clinical management due to its intricate pathophysiology. Emerging evidence underscores the pivotal role of autophagy dysregulation in the progression of diabetic cardiomyopathy, providing a novel avenue for therapeutic intervention. Noncoding RNAs (ncRNAs), a diverse class of regulatory molecules, have recently emerged as promising candidates for targeted therapeutic strategies.

Methicillin-resistant Staphylococcus aureus (MRSA) is a notorious pathogen that has emerged as a serious global health concern over the past few decades. Staphylococcal accessory regulator A (SarA) and 4,4'-diapophytoene synthase (CrtM) play a crucial role in biofilm formation and staphyloxanthin biosynthesis. Thus, the present study used a machine learning-based QSAR model to screen 1261 plant-derived natural organic compounds in order to identify a medication candidate with both biofilm and virulence inhibitory potential.

Obesity is a metabolic disorder distinguished by excess fat deposition in fatty tissues. Pancreatic lipase is one of the promising drug targets for treating obesity due to its critical role in the hydrolysis of triglycerides into mono-glycerides and free fatty acids. Due to unsatisfactory results and severe side effects of the current drugs available for treating obesity, there is an urgent need to identify novel therapeutic options.

A concoction of unhealthy eating, inactivity, and the adverse effects of specific drugs brings on obesity. The primary cause of Obesity is the storage of too much energy and triglycerides in adipocytes, particularly white adipose tissue (WAT). In addition to modifying one's lifestyle, anti-obesity medicines are increasingly used as adjuvant therapy.

The structure-based design introduced indoles as an essential motif in designing new selective estrogen receptor modulators employed for treating breast cancer. Therefore, here, a series of synthesized vanillin-substituted indolin-2-ones were screened against the NCI-60 cancer cell panel followed by in vivo, in vitro, and in silico studies. Physicochemical parameters were evaluated with HPLC and SwissADME tools.

A simple and sensitive bioanalytical high-performance liquid chromatographic method with ultraviolet detection was developed and validated for the quantification of febuxostat (FEB) in human plasma. Ketoprofen was used as an internal standard. The analytes were extracted from human plasma samples by precipitation with acetonitrile.

A rapid, simple, and selective method was developed for the determination of etodolac. The method depends on complexation of etodolac with copper (II) acetate and iron (III) chloride followed by extraction of complexes with dichloromethane and then measuring the extracted complexes spectrophotometrically at 684 and 385 nm in case of Cu (II) or Fe (III), respectively. Different factors affecting the reaction, such as pH, reagent concentration, and time, were studied.
