Abstract
Objective:
In this study, a simple triethylammonium salt of phosphoric acid (tri-ethylammonium dihydrogen phosphate) (4) in the liquid state was utilized as an inexpensive, effi-cient one-pot three components, solvent-free synthesis of thiazolidine-4-one derivatives, with good to excellent yields. Techniques such as FT-IR, 1H-NMR, 13C-NMR, 13C-NMR-DEPT-135, and MS. were used for the structural elucidation. The high biotic efficiency of the newly obtained compounds was confirmed by in vitro antimicrobial action against Gram-positive (S. Aureus), Gram-negative bacteria (P. Aeruginosa and E. Coli) and antifungal activity (C. Albicans) via mi-croplate titer dilution technique. Finally, a molecular docking study was performed with a re-solved crystal structure of S. Aureus D-alanine alanyl carrier protein ligase (PDB ID: 7VHV). This investigation aimed to synthesize a new series of thiazolidine-4-one derivatives combined with benzoxazole moiety.
Materials and Methods:
Ionic liquid assistance one-pot solvent-free synthesis method used to synthesize a new series of thiazolidine-4-one derivative 10(a-e).
Results:
Structural identification of new synthesis and biological evaluation via techniques of (IR, 1H-NMR, 13C-NMR, 13C-NMR-DEPT-135, and MS).
Conclusion:
Ionic liquid is utilized as an inexpensive, efficient one-pot three-component solventfree
synthesis of thiazolidine-4-one derivatives with good to excellent yields.
:
Most of the synthesized compounds showed high biological and anti-fungal activity, in line with
the docking study against mentioned microorganism and crystal structure of PDB (ID: 7VHV), respectively.
