Design, Synthesis, Molecular Docking, and Preliminary Pharmacological Screening of Some New Benzo[d]thiazol-2-ylamino Containing Chromen-2- One Derivatives with Atypical Antipsychotic Profile.

INTRODUCTION:Mental disorders are very serious complicated disorders. Schizophrenia is one of the most baffling mental disorders. The new series 7-(2-(benzo[d]thiazol-2- ylamino)ethoxy)-4-methyl-2H-chromen-2- synthesized in search of newer compounds for Schizophrenia.METHODS:Synthesis is done by refluxing in dry pyridine with various substituted 2-amino benzothiazoles derivatives (3a-3k) and 7-(2-Chloroethoxy)-4-methyl-2H-chromen-2-one (2). The molecular docking approach was used to screen these generated derivatives. Chem Bio Draw Ultra 12 was used to draw the compounds, which were then exposed to all potential conformations of compounds interacting with receptors. The Glide 7.6, Schrodinger 2017 Maestro 11.3 was used to achieve molecular docking. The Dopamine receptor 6CM4 serotonin 5TUD PDBs were acquired from the database of Brookhaven Protein. Using the OPLS 2005 force field, the ligand-protein hydrogen-bond network was acquired, along with the overall energy reduced. A glide score was used to rate the docking poses.RESULTS:The produced compounds have been identified with the use of analytical and spectral data. All of the produced substances were tested and analyzed for serotonin 5HT2 antagonistic and dopamine D2 activity, which can be considered as a measure of typical antipsychotic properties.CONCLUSION:Compounds 4b, 4c, 4e, 4g & 4i have demonstrated promising pharmacological action in preliminary studies. According to the preceding findings, compounds with electronwithdrawing substitutions, such as 4e & 4b, have a good atypical profile of antipsychotics.
