Background

Prexasertib Mesylate Hydrate (LY2606368 Mesylate Hydrate) is a potent, selective, ATP competitive CHK1 and CHK2 inhibitor, with a Ki of 0.9 nM for CHK1 and IC50s of <1 nM, 8 nM for CHK1 and CHK2, respectively. Prexasertib Mesylate Hydrate inhibits HT-29 CHK1 autophosphorylation (S296) and HT-29 CHK2 autophosphorylation (S516). Prexasertib Mesylate Hydrate shows potent anti-tumor activity, significantly abrogates the G2/M checkpoint in p53 deficient HeLa cells with an EC50 of 9 nM[1]. Chk1|0.9 nM (Ki)|Chk1|<1 nM (IC50)|Chk2|8 nM (IC50)

Prexasertib Mesylate Hydrate (LY2606368 Mesylate Hydrate) is an ATP competitive CHK1 inhibitor, with a Ki of 0.9 nM and an IC50 of <1 nM[1].Prexasertib (LY2606368) shows high anti-tumor activity against U-2 OS, Calu-6 and HeLa cells (IC50, 3, 3, 37 nM, respectively), causes DNA damage during S-phase requiring CDC25A and CDK2 at 4 μM[1].Prexasertib (0-20 nM) synergizes with olaparib (0-20 μM) to decrease cell viability in HGSOC cells[2].

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
