Discovery and biological evaluation of nitrofuranyl-pyrazolopyrimidine hybrid conjugates as potent antimicrobial agents targeting and methicillin-resistant .

Nitrofuran and pyrazolopyrimidine-based compounds possess a broad antimicrobial spectrum including Gram-positive and Gram-negative bacteria. In the present work, a series of conjugates of these scaffolds was synthesized and evaluated for antimicrobial activity against and methicillin-resistant (MRSA). Many compounds showed MIC values of ≤2 μg ml, with compound 35 demonstrating excellent activity (MICs: 0.

Role of riverbed sand mining on planform and cross-sectional morphology of Mayurakshi River, India.

Human interventions in the form of riverbed sand mining are escalating worldwide, especially in the humid tropics with excess population pressure exerting an elevated demand for sand as construction materials. Naturally, channel morphological alterations are observed for the tropical fluvial systems to a large extent. The present work examines the riverbed sand mining of the Mayurakshi River (India) during the last fifty years (1970-2020) using topographical maps, satellite images and field-based cross-sectional measurements.

Feasibility and acceptability of a mindfulness app-based intervention among patients with metastatic renal cell carcinoma: a multinational study.

Background: Patients with metastatic renal cell carcinoma (mRCC) experience emotional distress and limited supportive care access. This study assesses a mindfulness app's feasibility, acceptability, and preliminary efficacy in improving emotional symptoms, trait mindfulness, and overall quality of life for patients with mRCC on immunotherapy.

Methods: This multinational study recruited patients with mRCC undergoing immunotherapy from Brazil and the United States.

Nonbonded Molecular Interaction Controls Aggregation Kinetics of Hydrophobic Molecules in Water.

Molecular aggregation frequently occurs during material synthesis, cellular processes, and drug delivery systems, often resulting in decreased performance and efficiency. One major reason for such aggregation in an aqueous solution is hydrophobicity. While the basic understanding of the aggregation process of hydrophobic molecules from a thermodynamic standpoint is known, the present literature lacks a connection between the aggregation kinetics and the molecular basis of hydrophobicity.

Applications of Machine Learning Approaches for the Discovery of SARS-CoV-2 PLpro Inhibitors.

The global impact of SARS-CoV-2 highlights the need for treatments beyond vaccination, given the limited availability of effective medications. While Pfizer introduced , an FDA-approved antiviral targeting the SARS-CoV-2 main protease (Mpro), this study focuses on designing new antivirals against another protease, papain-like protease (PLpro), which is crucial for viral replication and immune suppression. NCATS/NIH performed a high-throughput screen of ∼15,000 molecules from an internal molecular library, identifying initial hits with a 0.
