T
ypical antipsychotics are used to treat a mental, baffling, severe disorder called Schizophrenia. The present
study focuses on design and synthesis of some novel derivatives. The novel series 7-(2-(benzo[d]thiazol-2-yl-
amino)ethoxy)-4-methyl-2H-chromen-2-one (4a-4k) was designed and synthesized by refluxing 2-amino ben-
zothiazole substituted derivatives (3a-3k) with 7-(2-chloroethoxy)-4-methyl-2H-chromen-2-one(2) in dry pyri-
dine. All the synthesized compounds were screened and evaluated for their dopamine D2 and serotonin 5HT2
antagonistic activity as a measure of typical antipsychotic property. Compounds 4b, 4c, 4e, 4g and 4i have
shown good preliminary pharmacological activity. Some of the better activity compounds were selected for
determination of acute toxicity (LD50) studies by OECD guidelines and also for effective dose (ED50) determi-
nation by probit log scale method. The therapeutic index (TI) of the selected compounds was determined for
selection of safer and better compounds. These synthesized derivatives were screened by molecular docking
method. The compounds were sketched using ChemBioDraw Ultra 12 and subjected for all possible confor-
mation of compounds interacting with receptors. Molecular docking was performed with the Glide 7.6, Mae-
stro 11.3 of Schrodinger 2017. PDB for Dopamine receptor 6CM4 and for serotonin 5TUD were obtained from
Brookhaven Protein database. The ligand-protein hydrogen bond network was obtained and total energy was
minimized by employing OPLS 2005 force field. The docking poses were ranked according to GlideScore. From
all above data results, compounds with electron withdrawing substitution like 4e and 4b has shown better
atypical antipsychotic profile.
