The HIV-1 invasion is initiated with the interaction of viralglycoproteingp120 and cellular receptor CD4. The binding mechanism reveals two major hotspots involved in gp120-CD4 interaction. The first one is a hydrophobic cavity (Phe43 cavity) on gp120 capped with phenyl ring of phe43CD4 and the second is the electrostatic interaction between positive charge of Arg59CD4 and negative charge of Asp368gp120

variation of substituents present on the phenyl ring and urea/thiourea group on pharmacophoric features. Further, the crystalstructure and supramolecular characteristics of two compounds 4c and 4f were analyzed through a single-crystal X-ray method and the Hirshfeld Surface Analysis, which shows hydrogen bonding through N-H···O and N-H···S interactions with the formation of ring motif in the crystal structure
