生物活性

製品説明 Felodipine (CGH-869) is a selective L-type Ca2+ channel blocker with IC50 of 0.15 nM.
in vitro Felodipine significantly relaxes KCl-contracted porcine coronary segments by blocking the Ca2+ channels, displaying ~50 times more potent than nifedipine (IC50 of ~8 nM) and ~430 times than verapamil (IC50 of ~65 nM). [1] Felodipine significantly induces the transcription and secretion of IL-6 and IL-8 with ED50 values of 5.8 nM and 5.3 nM in primary human VSMC and lung fibroblasts, respectively, while propranolol or furosemide fails to affect the expression of the two IL genes. [2] Felodipine blocks the muscarinic receptor-mediated (carbachol) Ca2+-dependent contraction of guinea pig ileum longitudinal smooth muscle (GPILSM) with an IC50 of 1.45 nM. [3] Felodipine at low concentration of 0.1 μM is sufficient to increases NOx generation, Ca2+-dependent NOS activity, and eNOS protein mass in rat endothelial cells. [4] Felodipine (10 μM) reduces nuclear translocation of p42/44 mitogen-activated protein kinase and Elk-1 activation stimulated by PDGF-BB, leading to the inhibition of human SMC proliferation. [5] Felodipine modestly blocks the Cav3.2 T-type Ca2+-channel with an IC50 of 6.8 μM. [6]
in vivo Oral administration of Felodipine significantly reduces the average blood pressure (BP) in rats with 5/6 renal ablation, but causes additional impairment of the already impaired renal autoregulation. [7] Administration of Felodipine significantly reduces systolic blood pressure (SBP), serum insulin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) by blocking NF-κB activation, and decreases macrophages in the aortic wall, leading to the modulation of vascular inflammatory response. [8]
特徴 Unlike many Ca2+ channel blockers, Felodipine does not have cardiac side effects due to high selectivity for vascular smooth muscle vs. myocardial tissue.

キナーゼアッセイ The effect of Felodipine on tension in coronary segments
The cylindrical coronary segments from porcine hearts are inverted and fixed horizontally between a stationary bottom pin and a top pin connected to the lever of a force-displacement transducer precalibrated with standard weights on a Grass model 5D polygraph. The cylindrical segments are bathed in 25 mL of PSS in a water jacketed tissue bath at 37 °C. The bath solution is bubbled continuously with a mixture of 95% O2-5% CO2. An initial resting tension of 10 g is set during a 2-hour equilibration period. After the equilibration, three to four successive contraction-relaxation cycles are induced with 35 mM KCl and subsequent washes with PSS until reproducible contractions are obtained. After the final response reached and maintained steady tension (16-25 g above resting tension), a cumulative dose-response curve for Felodipine is obtained. Additional aliquots of Felodipine are added only after the response to the previous dose has plateaued. The concentration of Felodipine that half-maximally relaxes the coronary from KCl-induced contraction (IC50) is determined from dose response curv
