Aim: Virtual screening selects compounds that resemble a known modulator or compounds that fit into the binding site of a target protein. Computational solvent mapping defines important chemical features for binding to a target protein. Results/methodology: We have tested the ability to use solvent mapping for generating a 'fake' ligand that is a negative image of the binding site. We used this fake ligand as a query for the program ROCS and to define the search space of the docking programs FRED and HYBRID.
Conclusion: The fake ligands perform comparably to or better than the ligands from crystal structures across a set of ten targets. Thus, the approach is suitable for guiding virtual screening and hit-to-lead optimization.

Catalysis plays a vital role in green chemistry by improving process efficiency, reducing waste, and minimizing environmental impact. A biochar-modified g-CN·SOH (BCNSA) catalyst was developed using biochar derived from amla seed powder and CNSA. CNSA was synthesized the reaction of g-CN with chlorosulfonic acid.

Basil, Ocimum basilicum L., is a widely cultivated aromatic herb, prized for its culinary and medicinal uses, predominantly owing to its unique aroma, primarily determined by eugenol for Genovese cultivars or methyl chavicol for Thai cultivars. To date, a comprehensive basil reference genome has been lacking, with only a fragmented draft available.

A newly published transparent embedding system, TESOS (Transparent Embedding Solvent System), ensures consistent submicron resolution imaging throughout the entire sample, and can be compatible with different microscopy systems. This method shows great potential in connectome mapping, and might be an optimal option for future 3D multiplex immunofluorescence and RNA in situ hybridization imaging.

HBT-DPI was a single-molecule multi-conformational fluorescent material and had unique applications for hydrophobic/hydrophilic mapping on large-scale heterogeneous surfaces. In this paper, the different proton transfer processes and luminescence mechanisms of HBT-DPI in Dichloromethane (DCM, no hydrogen bond (HB) receptor) and N, N-Dimethylformamide (DMF, HB receptor) solvents were systematically studied. Using the quantum chemistry method, the stable structures of HBT-DPI in two solvents were determined based on the Boltzmann distribution.

The current study focuses on the potential of second-generation antihistamines, which exhibit fewer side effects compared to first-generation drugs, to block the Histamine H receptor (HR) and mitigate allergic responses. We screened several derivatives of second-generation drugs taking Desloratadine (Deslo) and Acrivastine (Acra) as seed compounds. We performed molecular docking, drug-likeness, quantum chemical calculations, UV-visible and infrared spectroscopy, molecular electrostatic potential (MEP) mapping for understanding drug derivatives potential as efficient drugs and molecular dynamics (MD).
