DRD2 and pituitary gland adenoma: Savenau et al. [11] demonstrated that BIM-23A387 was more effective than either BIM-23023 (full agonist for SST2) or BIM-53097 (full agonist for D2R), either alone or in combination, in suppressing both GH- and PRL secretion in primary pituitary adenoma cells from patients previously treated with octreotide and/or quinagolide (a selective D2R agonist).
