The rapid outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China followed by its spread around world poses a serious global concern for public health. To this date, no specific drugs or vaccines are available to treat SARS-CoV-2 despite close relation SARS-CoV virus that caused similar epidemic 2003. Thus, there remains an urgent need identification and development antiviral therapeutics against SARS-CoV-2. conquer viral infections, inhibition proteases...

The rapid outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China followed by its spread around world poses a serious global concern for public health with almost 90000 people infected and thousands fatalities. To conquer viral infections, inhibition proteases essential proteolytic processing polyproteins is conventional therapeutic strategy. this date, no specific drugs or vaccines are available to treat SARS-CoV-2 despite close relation SARS-CoV-1 virus...

Oxidative reactions catalyzed by Cytochrome P450 enzymes (CYPs), which constitute the most relevant group of drug-metabolizing enzymes, are enabled their redox partner reductase (CPR). Both proteins anchored to membrane endoplasmic reticulum and CPR undergoes a conformational change in order interact with respective CYP transfer electrons. Here, we conducted over 22 microseconds molecular dynamics (MD) simulations combination protein–protein docking investigate changes necessary for...

Based on previous large-scale in silico screening several factor Xa inhibitors were proposed to potentially inhibit SARS-CoV-2 M pro . In addition their known anticoagulants activity this potential inhibition could have an additional therapeutic effect patients with COVID-19 disease. study we examined the binding of Apixaban, Betrixaban and Rivaroxaban use MicroScale Thermophoresis technique. Our results indicate that experimentally measured affinity is weak due rather negligible.

Retinoic acid-related orphan receptor γt (RORγt) regulates immune responses and its impaired function contributes to inflammatory autoimmune diseases may promote skin cancer. Synthetic inverse RORγt agonists block the production of Th17-associated cytokines including interleukin (IL)-17A IL-22 are under investigation for treatment such pathologies. Unintentional activation in skin, following exposure environmental chemicals, disease. Parabens UV-filters, frequently used as additives...

Molecular similarity search is an often-used method in drug discovery, especially virtual screening studies. While simple one- or two-dimensional metrics can be applied to databases containing billions of molecules a reasonable amount time, this not the case for complex three-dimensional methods. In work, we trained transformer model autoencode tokenized SMILES strings using custom loss function developed conserve similarities latent space. This allows direct sampling generated space based...

The three subtypes of estrogen-related receptors ERRα, ERRβ, and ERRγ are nuclear mediating metabolic processes in various tissues such as the skeletal muscle, fat tissue, bone, liver. Although knowledge on their physiological ligands is limited, they have been implicated drug targets for important indications including diabetes, cardiovascular diseases, osteoporosis. As other receptors, ligand binding pocket buried within core receptor connected to its surrounding by pathways. Here, we...

Abstract The efficient and accurate prediction of protein-ligand binding affinities is an extremely appealing yet still unresolved goal in computational pharmacy. In recent years, many scientists have taken advantage the remarkable progress deep learning applied it to address this issue. Despite all advances field, there increasing evidence that typically validation these methods not suitable for medicinal chemistry applications. This work assesses importance dataset quality proper splitting...

The pandemic of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a serious global health threat. Since no specific therapeutics are available, researchers around world screened compounds to inhibit various molecular targets SARS-CoV-2 including its main protease (Mpro) essential for viral replication. Due high urgency these discovery efforts, off-target binding, which is one major reasons drug-induced toxicity and safety-related drug attrition, was neglected. Here, we...

Abstract Following the assumption that chemically similar molecules exhibit biologcial properties, ligand-based virtual screening can be a valuable starting point in drug discovery projects. While 2D-based similarity metrics generally focus on scaffolds or substructures, 3D-based methods capture shape of molecule, allowing for identification compounds with different scaffolds. We recently published proof-of-concept study which demonstrated how Transformer model adapted to preserve 2D...

Abstract Drug development projects are getting increasingly more expensive while their success rate is stagnating. Safety issues attributed to off-target binding represent a major reason for the failure of new drugs. Besides desired on-target binding, small molecules may interact with off-targets, triggering adverse effects. Therefore, novel methods early recognition such that resource-efficient and cost-effective becomes vital. Here, we introduce PanScreen, an online platform automated...
