14 We conclude the following: 1) chiral histaprodifens interact differentially with H(1)R species isoforms; 2) gpH(1)R and rH(1)R, on one hand, and hH(1)R and bH(1)R, on the other hand, resemble each other structurally and pharmacologically; and 3) histaprodifens interact with H(1)R at multiple sites. histaprodifen gephyrin Homo sapiens
