Description of PBIT

IC50: 6, 3, 4.9, and 28 μM for JARID1A, JARID1B, JARID1C, and JARID1D, respectively

PBIT is a JARID1 family demethylases inhibitor.

JARID1B (also known as KDM5B or PLU1), a member of the JARID1 family of histone lysine demethylases, is identified for the demethylation of trimethylated lysine 27 in histone H3 that is a mark for actively transcribed genes. JARID1B is overexpressed in several cancers, such as prostate cancer, breast cancer, and lung cancer. Additionally, JARID1B is reported for mammary tumor formation in syngeneic or xenograft mouse models and JARID1B-expressing melanoma cells are related with increased self-renewal character.

In vitro: In previous study, PBIT was identified as JmjC histone demethylase inhibitor, which inhibited JARID1B with an in vitro IC50 of about 3 μM. Consistent with its inhibitory effect on JARID1B, PBIT treatment was able to inhibit the removal of H3K4me3 by JARID1B in cells. In addition, PBIT could inhibit the proliferation of cells expressing higher levels of JARID1B. These results suggested that PBIT could be regarded as a lead compound that could be further optimized for cancer therapy [1].

In vivo: Currently, there is no animal in vivo data reported.

Clinical trial: So far, no clinical study has been conducted.

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 saline, 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.
