Clear solution
5% DMSO 95% Corn oil
1.9mg/ml Taking the 1 mL working solution as an example, add 50 μL of 38 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.85mg/ml Taking the 1 mL working solution as an example, add 50 μL of 77 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

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