효소 저해제

This potent platelet aggregation inhibitor (FW = 256.09 g/mol; CAS 68475-42-3), also known as 6,7-dichloro-1,5-dihydroimidazo[2,1- b]quinazolin-2(3H)-one, BL-4162A, and Agrylin?, blocks the action of a variety of aggregating agents added platelet rich plasma, EC50 < 1 μg/mL, or 4 nM. Primary Mode of Action: Although the exact mechanism of its selective inhibition of megakaryocyte (MK) production of platelets remains uncertain, anagrelide is known to be a potent inhibitor of phosphodiesterase-II (IC50 = 36 nM) and lipoprotein-associated phospholipase A2 (or Lp-PLA2), the latter also known as platelet-activating factor acetylhydrolase (or PAF-AH). PDE-II hydrolyzes both cGMP and cAMP. Binding of cGMP to its regulatory GAF-B domain favors cAMP hydrolysis to 5’-AMP, thereby reducing cGMP hydrolysis to 5’-GMP. This property, which facilitates cross-regulation of the cAMP and cGMP pathways, suggests that a potent PDE-II inhibitor should potentiate the effects of cAMP and/or cGMP, the concentrations of which should increase in anagrelide-sensitive cells. Lp-PLA2 plays pivotal role in platelet maturation by specifically hydrolyzing Platelet-Activating Factor (PAF = acetyl-glyceryl-ether-phosphorylcholine) as well as other glycerophos-pholipids containing short, truncated, and/or oxidized fatty acyl groups at the sn-2 position of the glycerol backbone. At a final concentration of 100 ng/mL, anagrelide selectively blocks in vitro MK maturation, resulting in a 50% decrease in the total number of CD41a+ MKs. In humans, anagreline has the intriguing ability to promote as a species-specific platelet-lowering activity at dose levels lower than those required to inhibit platelet aggregation. Target(s): collagen- and immune complexinduced platelet aggregation and release; suppresses megakaryocytopoiesis by reducing the expression levels of the transcription GATA-1 and FOG-1 via a PDEIII-independent mechanism that is differentiation context-specific but does not involve inhibition of MPL-mediated early signal transduction events.
