New Solid Forms of the Antiviral Drug Arbidol: Crystal Structures, Thermodynamic Stability, and Solubility
TL;DR: Analysis of the conformational preferences of the Arbidol molecule in the crystal structures showed that it adopts two types of conformations, namely "open" and "closed", both of which correspond to local conformational energy minima of the isolated molecule.
Journal ArticleDOI
Styryl dyes. Synthesis and study of the solid-state [2+2] autophotocycloaddition by NMR spectroscopy and X-ray diffraction
Artem I. Vedernikov,Lyudmila G. Kuz’mina,S. K. Sazonov,N. A. Lobova,P. S. Loginov,Andrei V. Churakov,Yu. A. Strelenko,Judith A. K. Howard,Michael V. Alfimov,Sergey P. Gromov +9 more
TL;DR: In this paper, a number of styryl dyes of the pyridine and benzothiazole series were synthesized with the aim of investigating the solid-state [2+2] autophotocycloaddition (PCA) reaction.
Journal ArticleDOI
Weak Interactions Cause Packing Polymorphism in Pharmaceutical Two-Component Crystals. The Case Study of the Salicylamide Cocrystal
Artem O. Surov,Alex N. Manin,Alexander P. Voronin,Andrei V. Churakov,German L. Perlovich,Mikhail V. Vener +5 more
TL;DR: In this paper, two polymorphs of the salicylamide cocrystal with oxalic acid have been obtained and described, and the packing arrangements of the cocystal polymorphs, however, were found to be different, suggesting a rare example of packing polymorphism.
Journal ArticleDOI
A model proton-transfer system in the condensed phase: NH4+OOH−, a crystal with short intermolecular H-bonds
Andrei V. Churakov,Petr V. Prikhodchenko,Ovadia Lev,Alexander G. Medvedev,Tatiana A. Tripol’skaya,Mikhail V. Vener +5 more
TL;DR: The crystal structure of NH(4)(+)OOH(-) crystal is determined from single-crystal x-ray data obtained at 150 K and its advantages as a promising model for the experimental and DFT based molecular dynamics simulation studies of proton transfer along the chain are discussed.
Journal ArticleDOI
Reaction of germanes and digermanes with triflic acid: The route to novel organooligogermanes
Kirill V. Zaitsev,Andrey A. Kapranov,Yuri F. Oprunenko,Andrei V. Churakov,Judith A. K. Howard,Boris N. Tarasevich,Sergey S. Karlov,Galina S. Zaitseva +7 more
TL;DR: In this paper, germanium containing triflates were prepared from the reactions of trifluoromethanesulfonic acid with tetraphenylgermane and digermanes.
