Fenoldopam
Based on 4 publication(s) in Google Scholar
Fenoldopam (SKF-82526) is a selective dopamine D1 receptor agonist. Fenoldopam binds to rat D1B dopamine receptors (Kd = 11 nM) and human D1A receptors (Kd = 17 nM) in COS-7 cell membranes expressing the cloned receptors. Fenoldopam modulates dopamine receptor expression, induces vasorelaxation in vascular tissues, reverses glomerular hyperfiltration in rat models, increases intracellular cAMP levels, promotes DARPP-32 phosphorylation in small cell lung cancer (SCLC) cells, inhibits cytokine secretion, and downregulates T cell activation markers in activated human T cells. Fenoldopam can be used for research on hypertension, acute kidney injury, psoriasis, and small cell lung cancer.

Fenoldopam (SKF-82526) (40 min) competes for specific 125I-Sch 23982 binding sites in rat renal cortical membranes with a Ki of 1,975 nM (Tris-HCl buffer) and 1,895 nM (Dulbecco's buffer)[1].
Fenoldopam (1 nM-6 μM; 72 h) does not inhibit the proliferation of CD3/CD28-stimulated Jurkat leukemic T cells, in contrast to its inhibitory effect on normal activated T cells[2].
Fenoldopam (1 μM; 5 h) co-treated Theophylline (HY-B0809) increases intracellular cAMP levels in CD3/CD28-stimulated Jurkat cells[2].
Fenoldopam (1 μM; 10-30 min) increases DARPP-32 phosphorylation in small cell lung cancer (SCLC) H-69 cells and primary SCLC cultures[3].
Fenoldopam (1 μM; 30 180 min) induces cAMP accumulation in SCLC cells and increases BrdU incorporation in SCLC H-69 cells as well as primary SCLC cultures (SCLC H-3)[3].
Fenoldopam (0.1 μM; 48 h) reduces the secretion of TNF-α, IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8 and IL-10 by IL-2 activated PBMCs, and downregulates the expression of T cell activation markers CD69, CD28 and intracellular IL-2 in CD3+ T cells from psoriasis patients[4].
Fenoldopam (0.1 μM; 1 h) reduces the chemotactic migration of CD3/CD28-activated normal human T cells towards SDF-1/CXCL12 by 27-55%[4].
Fenoldopam (0.1 μM; 15 sec) induces depolarization of resting and activated normal human T cells[4].
Fenoldopam (10 pM-1 μM; 24 h) increases D1 and D3 receptor protein expression in a concentration- and time-dependent manner in rat aortic smooth muscle A10 cells[6].
Fenoldopam (0.1 μM; 24 h) increases D1/D3 receptor coimmunoprecipitation in A10 cells[6].
Fenoldopam (100 pM-1 mM) induces vasorelaxation in rat mesenteric arterial rings preconstricted with KCl (Emax = 83%, pED50 = 5.0)[6].
Fenoldopam binds to rat D1B dopamine receptors with a Kd of 11 nM and human D1A receptors with a Kd of 17 nM in COS-7 cell membranes expressing the cloned receptors[7].
Fenoldopam (1 nM-100 μM; cumulative) has minimal effect on mouse ductus arteriosus tone, and does not impair O2-or indomethacin-induced ductus constriction[8].
