Biological Activity

Description

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.

Targets

Thrombin ^[1]

5-39 nM(Ki)

In vitro
In vitro	Argatroban 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. ^[1] Argatroban can directly induce phenotype conversion of vascular smooth muscle cells with the resultant up-regulation of SMemb, PAI-1, and beta-actin mRNAs. ^[2]

In Vivo
In vivo	Argatroban 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. ^[3] 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. ^[4]

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
