Synthesis, molecular docking, ADMET evaluation and in vitro cytotoxic activity evaluation on RD and L20B cell lines of 3-substituted 5,5-diphenylimidazolidine-2,4-dione derivatives

15,15-Diphenyl-2,3,4,5,6,8,9,11,12-octa-hydro-imidazo[2,1-h][1,4,12]trioxa[7]thia-[9]azacyclo-tetra-decin-14(15H)-one

The title mol-ecule, C₂₃H₂₆N₂O₄S, adopts a cup-shaped conformation. In the crystal, layers lying parallel to the ab plane are formed by C-H⋯O hydrogen bonds and C-H⋯π(ring) inter-actions. The layers stack along the c-axis direction through normal van der Waals inter-actions.

3-(2-Bromo-eth-yl)-5,5-di-phenyl-imidazolidine-2,4-dione

The imidazolidine ring in the title mol-ecule, C₁₇H₁₅BrN₂O₂, is slightly ruffled [r.m.s. deviation = 0.0192 Å], while the attached phenyl rings at the C atom at the position between the amine and carbonyl centres are rotated well out of its mean plane [dihedral angles with the imidazolidine ring = 63.60 (8) and 76.4 (1)°]. In the crystal, a three-dimensional network features N-H⋯O and C-H⋯O hydrogen bonds together with C-H⋯π(ring) inter-actions.

3-Isobutyl-5,5-diphenylimidazolidine-2,4-dione

The imidazolidine ring in the title molecule, C19H20N2O2, is slightly `ruffled'. In the crystal, a layer structure is generated by N—H...O and C—H...O hydrogen bonds plus C—H...π(ring) interactions.
