AL-8810 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Verwenden

  AL 8810 is an 11β-fluoro analog of PGF2α which acts as a potent and selective antagonist at the FP receptor. AL 8810 has weak intrinsic agonist activity on FP receptor preparations in the 200-300 nM range, yet it fully antagonizes the activity of the potent FP receptor agonist fluprostenol at this concentration, with EC50 values of approximately 430 nM. AL 8810 fully antagonized the bimatoprost-induced calcium mobilization in Swiss 3T3 fibroblasts at 100 μM, indicating that bimatoprost acts as an FP agonist in this preparation. The Ki for the inhibition of several potent agonists at the cloned human ciliary body FP receptor is in the range of 1-2 μM.

• Definition

  ChEBI: AL 8810 is a long-chain fatty acid.

• Biologische Aktivität

  al-8810 is a novel prostaglandin f2α analog that acts as a selective antagonist of prostaglandin f2α (fp) receptor.prostaglandin receptors are a group of g-protein coupled receptor that exhibited a variety of functions in regulation of blood pressure and renal function; smooth muscle contraction; inhibition of plate aggregation; immune response etc.al-8810 has a ec50 of 261 ± 44 nm against fp receptor in the a7r5 rat thoracic aorta smooth muscle cells and a ec50 of 186 ± 63 nm in swiss mouse 3t3 fibroblasts. in addition, al-8810 antagonizes the response to 100 nm fluprostenol (ki = 426 ± 63 nm) in a concentration- dependent manner in a7r5 cells. [1]in the h-tm cells, al-8810 antagonizes the (±) fluprostenol-induced pi turn over responses concentration dependently (ki=2.56 ± 0.62 μm). al-8810 also antagonizes bimatoprost, travoprost acid, latanoprost acid and travoprost acid. [2] in hcm cells, 1 μm al-8810 blocks the 85% pgf2-induced mmp-2 secretion and 66% pgf2α-induced activation of erk1/2. [3]
