Argatroban (MCI-9038)

InformationArgatroban (MCI-9038) Argatroban (MCI-9038) is a potent and selective synthetic thrombin inhibitor with K i ranging from 5 nM to 39 nM, used as an anticoagulant.In vitroArgatroban is a potent and selective synthetic thrombin inhibitor with Ki values against thrombin ranging from 5 nM to 39 nM. Argatroban has antithrombotic properties in a wide variety of animal models of both platelet-rich and erythrocyte-rich thrombosis. Argatroban dose-dependently prevents thrombus formation with an estimated ED50 of 125 μg/kg in this test. Argatroban produces a dose-dependent increases in the thrombin time with a 511% increase at the highest dose used with only a 73% increase in the APTT at this dose. Argatroban can directly induce phenotype conversion of vascular smooth muscle cells with the resultant up-regulation of SMemb, PAI-1, and beta-actin mRNAs.In vivoArgatroban inhibits the formation of microthrombi up to 3 hours after middle cerebral artery (MCA) occlusion; beyond 3 hours, it is ineffective. Argatroban also significantly reduces the size of ischemic cerebral lesions at 6 hours after MCA occlusion. Argatroban (0.3 mg/h/rat) significantly decreases the number of microthrombi 1 day after distal middle cerebral artery (dMCA) occlusion in the rat distal middle cerebral artery occlusion model. Argatroban (0.1 and 0.3 mg/h/rat) significantly reverses a decrease in regional cerebral blood flow (rCBF) 1 day after distal middle cerebral artery (dMCA) occlusion. Argatroban (0.3 mg/h/rat) also significantly reduces the size of the cerebral infarction.Cell Datacell lines：Normal human dermal fibroblasts, Scleroderma fibroblastsConcentrations：Incubation Time：Powder Purity:≥99%.
