Trapidil was used to study the mechanism of osteoclastogenesis and bone loss in mice.[1]
生化/生理作用
Antiplatelet agent; competitive inhibitor of PDGF receptor; phosphodiesterase inhibitor, vasodilator
Trapidil is an antiplatelet agent that acts in part as a phosphodiesterase inhibitor and as a competitive inhibitor of the platelet-derived growth factor (PDGF) receptor. Trapidil, with its vasodilator and NO releasing effect may have some potential to diminish the tissue injury. Trapidil suppresses platelet-derived growth factor (PDGF)-induced vascular smooth muscle cell (VSMC) proliferation by inhibiting Raf-1/extracellular signal-regulated kinase (ERK) via cAMP/protein kinase A (PKA). In addn. to cAMP/PKA activation, trapidil inhibits RhoA/ROCK activation.

A novel analytical technique able to determine the anti-ischemic drug trapidil in human serum and urine is proposed. In order to achieve satisfactory sensitivity and selectivity, an extraction procedure was required to isolate the drug from complex matrixes such as

We aimed to detect the protective effect of trapidil in ischemia-reperfusion (IR) injury due to ovarian torsion and detorsion. Thirty-two pubertal New Zealand albino rabbits were used. Adnexal torsion was created by rotating the left adnexa including the tubal and

Chronic hyperparathyroidism (HPT) is a common cause of metabolic bone disease. These studies investigated the underlying cellular and molecular mechanisms responsible for the detrimental actions of elevated parathyroid hormone (PTH) on the skeleton. Bone biopsies from hyperparathyroid patients revealed an

We aimed to detect the preventive effects of trapidil in ischemia-reperfusion (IR) injury due to testicular torsion and detorsion. Forty prepubertal albino rats were used. In the IR group, torsion was created by rotating the left testis over 2 h
