Teriparatide

特立帕肽
Mechanism of action:
Teriparatide 是一種副甲狀腺素類似物(parathyroid hormone analog),為人類副甲狀腺素第 1-34 胺基酸片段(recombinant human PTH 1-34)。Teriparatide 會與骨骼中成骨細胞(osteoblast)表面的副甲狀腺素-1 受體(parathyroid hormone 1 receptor)結合,啟動 Gs 蛋白-腺苷酸環化酶(adenylyl cyclase)路徑,使 cAMP 上升,活化蛋白激酶 A(protein kinase A),誘發一系列促進骨形成的基因表達,促進成骨細胞分化。
