Biological Activity

Description MRS2578 is a potent P2Y6 receptor antagonist with IC50 of 37 nM, exhibits insignificant activity at P2Y1, P2Y2, P2Y4,and P2Y11 receptors.

37 nM
In vitro

MRS2578 selectively blocks P2Y6 receptor activity versus activity at P2Y1, P2Y2, P2Y4 or P2Y11 receptors. MRS2578 (1 μM) completely blocks the protection by UDP undergoing TNFalpha-induced apoptosis in 1321N1 astrocytoma cells. [1] MRS 2578 inhibits basal NF-κB activity in time and dose dependent manner in HMEC-1 cells transfected with 0.25 μg NF-κB promoter reporter. MRS 2578 (10 μM) completely abolishes TNF-α induced NF-κB reporter activity in HMEC-1 cells. MRS 2578 (10 μM) significant reduces TNF-α–induced proinflammatory gene expression in HMEC-1 cells. [2] MRS 2578 potentiates ATPγS and UDP response at concentrations below 316 nM whereas above this concentration, MRS 2578 inhibits ATPS- and UDP-induced IP accumulation in neonatal rat cardiac myofibroblasts. [3] MRS2578-treated mice shows reduced bronchial hyperresponsiveness toward methacholine in OVA-sensitized mice. MRS2578 completely blocks UDP-induced the release of IL-6, KC, and IL-8 in lung epithelial cells. [4]

In vivo MRS 2578 (10 μM) attenuates Keratinocyte-derived chemokine serum protein levels in LPS-induced vascular inflammation in C57BL/6 mice. [2] MRS2578 (10 μM, intratracheally) reduces BALF eosinophilia and the levels of IL-5 and IL-13 in the BALF in OVA-sensitized mice and leads to a markedly attenuated change in methacholine responsiveness after OVA challenge. MRS2578 (10 μM, intratracheally) inhibits house dust mite–induced allergic airway inflammation in OVA-sensitized mice. MRS2578 (10 μM, intratracheally) reduces of IL-6 and KC levels in BALF in OVA-sensitized mice. [4]

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.
