体外研究(In Vitro)
(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.(D-Trp12,Tyr34)-pTH (7-34) amide (0.1-10 μM) attenuates inhibition of NapiT promoted by 1 nM of either PTHrP or PTH. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
(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. has not independently confirmed the accuracy of these methods.
