Enitociclib (BAY 1251152)

Synonyms: (+)-BAY-1251152 

Enitociclib (BAY 1251152) is a potent PTEFb/CDK9 inhibitor with an IC50 value of 3 nM for CDK9 and an at least 50-fold selectivity against other CDKs in enzymatic assays. BAY1251152 binds to and blocks the phosphorylation and kinase activity of CDK9, thereby preventing PTEFb-mediated activation of RNA Pol II and leading to the inhibition of gene transcription of various anti-apoptotic proteins.

In vitro

BAY 1251152 (compound 2) significantly inhibits CDK9 and CDK2 with IC50 of 3 nM and 360 nM, respectively. BAY 1251152 (compound 2) shows cellular potency in MOLM13 with IC50 of 29 nM.[1] [2]
Cell Research Cell lines HeLa, NCI-H460, A2780, DU 145, HeLa-MaTu-ADR, Caco-2, B16F10, MOLM-13
Concentrations 0.001 μM - 10 μM
Incubation Time 4 days
Method

Cultivated tumour cells are plated in a 96-well multititer plate in 200 of their respective growth medium supplemented 10% fetal calf serum. After 24 hours, the cells of one plate (zero-point plate) are stained with crystal violet, while the medium of the other plates is replaced by fresh culture medium (200 μl ), to which the test substances are added in various concentrations (0 μM, as well as in the range of 0.001 -10 μM; the final concentration of the solvent dimethyl sulfoxide is 0.5%). The cells are incubated for 4 days in the presence of test substances.
In Vivo
In vivo

BAY 1251152 demonstrates excellent efficacy upon i.v. treatment in xenograft models (e.g. MOLM13) in mice and rats. BAY 1251152 is currently being evaluated in Phase I studies to determine the safety, tolerability, pharmacokinetics and initial pharmacodynamic biomarker response in patients with advanced cancer.[2]

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.
