Cocrystals of Modafinil-Nicotinic Acid: A Novel Cocrystal for Enhanced Bioavailability

  • Tanmoy Ghosh,
  • Thimmasetty Juturu,
  • Shashank Nayak Nagar and
  • Shwetha Kamath

In this work, we are the first to identify and report pharmaceutically effective cocrystals of the poorly soluble drug Modafinil (MOD) using a crystal engineering approach. A multi-component system of MOD with nicotinic acid (NIC) as the coformer at...

New Quaternary Chalcogenides Tl2MIIMIV3Se8 and Tl2MIIMIVX4

  • Andrii Selezen,
  • Yuri Kogut,
  • Lyudmyla Piskach and
  • Lubomir Gulay

New quaternary thallium-containing chalcogenides Tl2MIIMIV3X8 and Tl2MIIMIVX4 were synthesized, and their crystal structure was determined by XRD. Three Tl2MIIMIV3X8 chalcogenides crystallize in orthorhombic symmetry (S.G. P212121; Tl2CdGe3Se8 lattic...
