title: Synthesis and BZR affinity of pyrazolo[1,5-a]pyrimidine derivatives. Part 1: study of the structural features for BZR recognition.
abstract: Examination of the pharmacophoric points of the pyrazolo[1,5-a]pyrimidine derivatives, ligands for BZR, previously published led us to the design of a novel class of 3,6-diaryl-4,7-dihydro-pyrazolo[1,5-a]pyrimidin-7-ones and to determine the groups involved in the BZR recognition.
