Tenidap
Based on 1 Customer Validation
Tenidap (CP-66248) is an orally active dual inhibitor of 5-LOX and COX with anti-inflammatory and immunomodulatory properties. Tenidap downregulates the expression of IL-1 receptors in chondrocytes, reduces the release of pro-inflammatory cytokines such as IL-1, IL-6 and TNF-α, and inhibits MMP production and cartilage degradation. Tenidap also blocks bone resorption and leukocyte adhesion to vascular endothelium, interferes with ion and pH changes associated with mouse sperm capacitation, and selectively enhances the activity of hKir2.3 channels (EC50=1.3 μM). Tenidap is applicable to research related to rheumatoid arthritis.

Tenidap potently inhibits leukotriene B4 and prostanoid synthesis in human polymorphonuclear leukocytes in vitro[1].
Tenidap (20 μg/mL; therapeutic concentrations) reduces IL-1β receptor expression in normal and osteoarthritic human chondrocytes, and potently suppresses IL-1β-induced collagenase and stromelysin synthesis and mRNA levels in these cells[2].
Tenidap potently inhibits bone resorption induced by parathyroid hormone, vitamin D3, IL-1α, TNF-α, and prostaglandin E2 in in vitro bone cultures, with effects independent of prostaglandin synthesis suppression[2].
Tenidap inhibits vitamin D3-induced CD14 expression, partially reverses reduced 3H-thymidine uptake, and suppresses early-stage IFN-γ-stimulated complement C2 production in HL-60 myelomonocytic cells, with no effect on C2 production in differentiated cells[2].
Tenidap potently inhibits adhesion of neutrophils, eosinophils, monocytes, and T cells to endothelial cells in in vitro adhesion assays, including IL-1-stimulated models[2].
Tenidap (0.01-10 μM; 50 min) potently and dose-dependently enhances Ba2+-sensitive 86Rb+ efflux through hKir2.3 channels in CHO cells with an EC50 of 402 nM[4].
Tenidap (30 μM; 5 min, not specified) is selective for hKir2.3 channels, as it has little or no effect on hKv1.5, μ1 Na+, or hKir2.1 channels in stably transfected cells[4].
