Michalina Rusek, Karolina Kwaśna, Armand Budzianowski, and Andrzej Katrusiak

DOI: 10.1021/acs.jpcc.9b09428

Synopsis

Several structures of hexafluorobenzene at low temperature at atmospheric pressure or high pressure at room temperature have been published.

There are also structures of the new high-pressure phase.

Designing of diamino based esterases inhibitors; synthesis, characterization, density functional theory and molecular modeling

Muhammad Asam Raza, Kiran Fatima, Zenab Saqib, Jan K. Maurin, Armand Budzianowski

Highlights

  • Six diamine based dithoic acids were proposed for esterases inhibitors.
  • The most potent molecules on the basis of theoretical studies were synthesized.
  • Both theoretical and experimental studies were in close agreement.

Keywords: Esterases; Density functional theory; Molecular docking; Dithioic acid

Highlights

  • Holmium-doped monoclinic KGd(WO4)2 nanoparticles were used in the research.
  • Nanoparticles were synthesized by the mechano-chemical method.
  • KGd(WO4)2 is promising for biomedical imaging applications.
  • The cytotoxicity assays of KGW nanoparticles doped with 10% Ho ions were performed.
  • WST-8 shows that material is stable and does not cause toxic effect on J774.1 cells.
