Elucidating the mechanism of substrate encapsulation in supramolecular resorcin[4]arene using enhanced sampling simulations.

Supramolecular cages have emerged as promising catalysts for diverse chemical transformations. Analogous to enzymes, these cage catalysts utilize non-covalent interactions to encapsulate substrates within their well-defined cavities, thereby enabling highly selective catalysis. Among them, resorcin[4]arene-based supramolecular cages have gained particular interest due to their structural versatility and catalytic potential.

Safety and efficacy of ivosidenib in the treatment of isocitrate dehydrogenase 1 mutant cholangiocarcinoma and acute myeloid leukemia: a systematic review and meta-analysis.

Isocitrate dehydrogenase 1 (IDH1) mutations have gained interest because of their association with malignancies, including cholangiocarcinoma and acute myeloid leukemia. Ivosidenib, an inhibitor of IDH1 mutations, inhibits the formation of the oncometabolite D-2-HG, restoring normal cellular turnover and inhibiting tumorigenesis. In July 2024, a literature search was done using these databases: PubMed, Cochrane Library, and Embase.

Locality-Sensitive Hashing-Based Data Set Reduction for Deep Potential Training.

Machine learning methods provide a great scope for developing ab initio quality potentials for diverse systems, ranging from simple fluids to complex solids. However, these methods typically require extensive data sets for effective model training, and the accuracy of the ML potential is highly dependent on data quality, necessitating expensive ab initio calculations. To address this challenge, we present a novel method based on locality-sensitive hashing, designed to minimize the data set size, thereby reducing the number of expensive quantum chemical calculations while preserving the data set's diversity and accuracy.

Unveiling the Role of Solvent in Solution Phase Chemical Reactions using Deep Potential-Based Enhanced Sampling Simulations.

We have used a deep learning-based active learning strategy to develop level accurate machine-learned (ML) potential for a solution-phase reactive system. Using this ML potential, we carried out enhanced sampling simulations to sample the reaction process efficiently. Multiple transitions between the reactant and product states allowed us to calculate the converged free energy surface for the reaction.

In-hospital outcomes in COVID-19 patients with non-alcoholic fatty liver disease by severity of obesity: Insights from national inpatient sample 2020.

Annickia affinis (Exell) Versteegh & Sosef methanol stem bark extract, potent fractions and isolated Berberine alkaloid target both blood and liver stages of malaria parasites.

Ethnopharmacological Relevance: Having identified Annickia affinis as the most potent antiplasmodial plant constituent in a hepta-herbal Agbo-iba (HHA) formula commonly used to manage malaria in Benin city, Nigeria, we have in this study attempted to identify the specialized metabolites responsible for antiplasmodial activity of A. affinis through anti-blood stage malaria parasite activity guided isolation of potent molecules from its stem bark methanol extract. After that, phenotypic effects, including stage-specific kill kinetics, were investigated.

Loperamide, a peripheral Mu-Opioid receptor agonist, attenuates chemotherapy-induced neuropathic pain in rats.

Opioids are employed in the management of chemotherapy-induced neuropathic pain (CINP) when other pain management approaches have failed and proven ineffective. However, their use in CINP is generally considered as a second-line or adjunctive therapy owing to their central side effects and development of tolerance with their long-term usage. Targeting peripheral sites may offer several advantages over the conventional CNS-based approaches as peripheral targets modulate pain signals at their source, thereby relieving pain with higher specificity, efficacy and minimizing adverse effects associated with off-site CNS actions.

Cu(I)/-Imine Ligand Catalyzed C(sp)-C(sp) Coupling of Alkyl Bromides with Alkynes: Scope and Mechanistic Investigation.

We have developed an efficient Cu/,-bidentate imine ligand catalytic system for C(sp)-C(sp) coupling to obtain internal alkynes, di/trisubstituted allenes and strained bridged cyclic lactams in moderate to excellent yields from readily available alkyl(benzyl) bromides in one-pot transformation. Density Functional Theory (DFT) assisted mechanistic study along with control experiments support the involvement of bialkynylated copper species which undergo single electron transfer (SET) with alkyl halides to generate radical intermediate in the reaction. The ,-bidentate imine ligand plays a vital role in stabilization of intermediate copper complex and facilitates the product formation.

Insecticidal potential of extracts, fractions, and molecules of Aconitum heterophyllum Wall ex. Royle against aphid Aphis craccivora Koch (Hemiptera: Aphididae).
