生物活性
Manidipine dihydrochloride (CV-4093) is a hydrochloride salt of manidipine that is a lipophilic, third-generation, highly vasoselective dihydropyridine calcium antagonist with an IC50 of 2.6 nM. Manidipine dihydrochloride (CV-4093) causes systemic vasodilation by inhibiting the voltage-dependent calcium inward currents in smooth muscle cells. Manidipine dihydrochloride (CV-4093) is used clinically as an antihypertensive. Manidipine dihydrochloride (CV-4093) suppressed the DNA synthesis of vascular smooth muscle cells (VSMC) dose dependently at concentrations of more than 10 nM. Mandipine hydrochloride (1 uM) suppressed proliferation of VSMC to 50% of the control value. Manidipine hydrochloride stimulated the synthesis of GAG at concentrations above 0.01 nM. Manidipine hydrochloride (10 nM) stimulated synthesis of glycosaminoglycans (GAG) to 450% of control.

| 方法 | Measuring the mitogenic effect by the amout of [3H]thymidine incorporated into DNA of human MCs and by assessment of cell proliferation. In brief, seeding 1 ?105 quiescent cells into a 25-mL cell culture bottle and keeping in low serum medium (0.1% FCS). On the next day, the cells are preincubated for 3 hours with Manidipine (10 nM) followed by stimulation with PDGF-BB (10 ng/mL) or incubated with low serum medium abone. Replacing the medium each day, and counting the cells at days 1, 3 and 5. |

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
