Biological Activity

Description Felodipine (CGH-869) is a selective L-type Ca2+ channel blocker with IC50 of 0.15 nM.
Features Unlike many Ca2+ channel blockers, Felodipine does not have cardiac side effects due to high selectivity for vascular smooth muscle vs. myocardial tissue.
Targets
L-type calcium channel [1]
0.15 nM
In vitro
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
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.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
