ABSTRACT
(R)/(S)-the two enantiomers of 3-substituted-1-[2-(5)-3-substituted-4-benzyl-5-oxo-4-phenyl-2-thioxoimid-azolidin-1-yl]ethyl/propyl-5-benzyl-5-phenyl-2-thioxoimidazolidin-4-ones were formed during the diastereoselective reaction between N,Nâ³-1,ω-alkanediylbis[N'-organylthiourea] derivatives and 2,3-diphenylcyclopropenone in refluxing ethanol. The structures of the isolated compounds were confirmed by NMR, IR, mass spectra and elemental analyses. Moreover, single-crystal X-ray structure analysis was also used to elucidate the structure of the isolated compounds. The mechanism describes the reaction was also discussed. The tested compounds showed EGFR inhibitory activity with IC50 values ranging from 90 to 178 nM in comparison to the erlotinib as a reference with IC50 value of 70 nM. Compound 4c (R = allyl, n = 3) was found as the most potent antiproliferative, had the highest inhibitory effect on EGFR with an IC50 value of 90 nM, compared to erlotinib's IC50 value of 70 nM. The second and third-most active compounds were 4e (R = phenyl, n = 3) and 4d (R = ethyl, n = 3) and with IC50 values of 107 nM and 128 nM. These findings imply that the compounds tested had a significant antiproliferative effect as well as the ability to act as an EGFR inhibitor. Docking studies showed that compound 4c showed high affinity to EGFR based on its docking score (S; kcal/mol) within five test compounds.
