2-Aryl-2,5-dihydropyridazino[4,3-b]indol-3(3H)-ones: novel rigid planar benzodiazepine receptor ligands

Bioorg Med Chem. 1993 Dec;1(6):437-46. doi: 10.1016/s0968-0896(00)82154-9.

Abstract

A series of 2-aryl-2,5-dihydropyridazino[4,3-b]indol-3(3H)-ones 5 were prepared and evaluated for their ability to inhibit radioligand binding to BZR, and to prevent sound and pentylenetetrazole (PTZ) induced seizures in mice. The biological and pharmacological results are discussed in the light of some recently proposed pharmacophore models and compared through molecular orbital and molecular modeling studies to those obtained from the close pyrazoloquinoline analogs 6.
