Abstract : Our efforts to discover potent, orally bioavailable type II calcimimetic agents for the treatment of secondary hyperparathyroidism focused on the development of ring constrained analogues of the known calcimimetic R-568. The structure-activity relationships of various substituted heterocycles and their effects on the human calcium-sensing receptor are discussed. Pyrazole 15 was shown to be efficacious in a rat in vivo pharmacodynamic model.
