WDR5-0103
Based on 2 publication(s) in Google Scholar
WDR5-0103 (WD-Repeat Protein 5-0103) is a potent and selective WD repeat-containing protein 5 (WDR5) antagonist with a Kd of 450 nM. WDR5-0103 competitively binds to the peptide-binding pocket of WDR5, blocking the interaction between WDR5 and mixed-lineage leukemia (MLL) protein and inhibiting the methyltransferase activity of MLL. WDR5-0103 is mainly used in the research of cancer and neurodegenerative diseases.

Biological Activity
WDR5-0103 (5-20 μM; 72 hours) can sensitize ABCB1- or ABCG2-overexpressing multidrug-resistant cancer cells to conventional cytotoxic drugs in a concentration-dependent manner in experiments with multiple cell lines[2].
WDR5-0103 (1-10 μM; 72 hours) does not alter the protein expression of ABCB1 or ABCG2 in multidrug-resistant cancer cells[2].
WDR5-0103 (10 μM; 48 hours) can significantly restore drug-induced apoptosis in ABCB1- or ABCG2-overexpressing multidrug-resistant cancer cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:P301S transgenic Tau mice (both male and female, 5-6 months old)[3]
-
Dosage:2.5 mg/kg (dissolved in DMSO and diluted with saline, DMSO concentration of working solution < 0.2%)
-
Administration:Intraperitoneal injection, once a day, for 3 days
-
Result:In behavioral tests, the discrimination ratio in the novel object recognition test and the spatial memory index in the Barnes maze test were significantly improved, indicating the amelioration of cognitive deficits.
Western blot analysis showed that the decreased levels of synaptic GluR1, NR1, and NR2A subunits were remarkably restored.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
