Structural determinants influencing halogen bonding: a case study on azinesulfonamide analogs of aripiprazole as 5-HT_1A, 5-HT₇, and D₂ receptor ligands.

ABSTRACT: A series of azinesulfonamide derivatives of long-chain arylpiperazines with variable-length alkylene spacers between sulfonamide and 4-arylpiperazine moiety is designed, synthesized, and biologically evaluated. In vitro methods are used to determine their affinity for serotonin 5-HT_1A, 5-HT₆, 5-HT₇, and dopamine D₂ receptors. X-ray analysis, two-dimensional NMR conformational studies, and docking into the 5-HT_1A and 5-HT₇ receptor models are then conducted to investigate the conformational preferences of selected serotonin receptor ligands in different environments. The bent conformation of tetramethylene derivatives is found in a solid state, in dimethyl sulfoxide, and as a global energy minimum during conformational analys
