(D-Trp12,Tyr34)-pTH (7-34) amide (bovine) is a potent and competitive antagonist of parathyroid hormone (PTH), with a K_i of 69 nM in bovine renal cortical membrane. (D-Trp12,Tyr34)-pTH (7-34) amide (bovine) can be used for growth and development regulation^[1][2].

Ki: 69 nM (PTH)^[1]

(D-Trp12,Tyr34)-pTH (7-34) amide (0.05-10 μM) causes a concentration-dependent inhibition of PTHrP or PTH-stimulated cAMP formation in opossum kidney (OK) cells^[2].
(D-Trp12,Tyr34)-pTH (7-34) amide (0.1-10 μM) attenuates inhibition of Nap_iT promoted by 1 nM of either PTHrP or PTH^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

(D-Trp12,Tyr34)-pTH (7-34) amide (1 mg/mL once, 0.1 mg/mL for 6 h; i.v.) has no significant effect on serum calcium levels in hypercalcemic athymic nude mice bearing a human squamous cell carcinoma of the lung^[3].
