Heterocyclic thiones have recently been identified as reversible covalent warheads, consistent with their mild electrophilic nature. Little is known so far about mechanism of action in labelling nucleophilic sidechains, especially cysteines. The vast number tractable cysteines promotes a wide range target proteins to examine; however, our focus was put on functional We chose the main protease SARS-CoV-2 harboring Cys145 at active site that structurally characterized and clinically validated inhibitors. screened an in-house, cysteine-targeting inhibitor library which resulted several fragment hits benzoxazole, benzothiazole benzimidazole cores. Thione derivatives Michael acceptors were selected for further investigations objective exploring inhibition using thoroughly benchmarking studies. Classical hybrid quantum mechanical/molecular mechanical (QM/MM) molecular dynamics simulations carried out revealed new cysteine by thione derivatives, supported QM free energy calculations experimental results. Our study shows recognition step plays crucial role overall binding both sets molecules.

Molecular simulations are an essential asset in the first steps of drug design campaigns. However, requirement high-throughput limits applications mainly to qualitative approaches with low computational cost, but also accuracy. Unlocking potential more rigorous quantum mechanical/molecular mechanics (QM/MM) models combined molecular dynamics-based free energy techniques could have a tremendous impact. Indeed, these two relatively old emerging as promising methods field. This has been favored by exponential growth computer power and proliferation powerful data-driven methods. Here, we briefly review recent advances applications, give our perspective on impact that QM/MM free-energy machine learning-aided algorithms can design.

Abstract Quantum computing, with its superior computational capabilities compared to classical approaches, holds the potential revolutionize numerous scientific domains, including pharmaceuticals. However, application of quantum computing for drug discovery has primarily been limited proof-of-concept studies, which often fail capture intricacies real-world development challenges. In this study, we diverge from conventional investigations by developing a hybrid pipeline tailored address genuine design problems. Our approach underscores computation in and propels it towards more scalable system. We specifically construct our versatile two critical tasks discovery: precise determination Gibbs free energy profiles prodrug activation involving covalent bond cleavage, accurate simulation interactions. This work serves as pioneering effort benchmarking against veritable scenarios encountered design, especially bonding issue present both case thereby transitioning theoretical models tangible applications. results demonstrate integration into real world workflows.

A remarkably simple and efficient double defluorinative [3 + 3] annulation approach involving N-phenyl-α-fluoro-α-phenylsulfonylacetamide 2-CF3-alkenes to access N-phenyl-3,6-difluoropyridone derivatives has been achieved. The key the success of this single-step synthesis difluoropyridones is strategic utilization for consecutive allylic vinylic substitution reactions a desulfonylation cascade. We could also show that these serve as versatile platform C-6-selective functionalizations.
