(S)-PHA533533
Based on 1 Customer Validation
(S)-PHA533533 is a CDK2 and CDK5 inhibitor with blood-brain barrier permeability, with IC50 values of 37 nM and 55 nM, respectively. (S)-PHA533533 effectively restores UBE3A expression by downregulating UBE3A-ATS and relieving the epigenetic silencing of paternal UBE3A in mature neurons. (S)-PHA533533 can be used for the research of Angelman syndrome.

(S)-PHA533533 (1 μM; 72 h) potently activates paternal Ube3a expression in primary cortical neurons from Ube3am+/pYFP mice[1].
(S)-PHA533533 (72 h) activates paternal Ube3a expression in primary cortical neurons from Ube3am+/pYFP mice, with an EC50 of 0.54 μM, an EMAX of 80.02% paternal UBE3A-YFP-positive neurons, and a CC50 of 2.98 μM[1].
(S)-PHA533533 (1 μM; 72 h) activates paternal Ube3a expression in primary cortical neurons derived from Ube3am+/pYFP mice, and this process is independent of the inhibition of CDK2, CDK5 and TOP1[1].
(S)-PHA533533 (72 h) downregulates UBE3A-ATS and relieves the silencing of paternal UBE3A in forebrain cortical neurons derived from ASdel1-0ΔI-P human induced pluripotent stem cells, with an EC50 of 0.59 μM for UBE3A induction and an IC50 of 0.42 μM for UBE3A-ATS downregulation[1].

Result:Significantly increased Ube3a mRNA levels in all examined brain regions (olfactory bulb, cortex and hippocampus, subcortical tissues, cerebellum) compared to saline-treated control AS mice.
Reached Ube3a mRNA levels measured in saline-treated wild-type mice in the olfactory bulb.
Widespread reinstated UBE3A protein throughout the brain, with increased UBE3A signal detected in all NeuN-positive mature neurons across multiple brain regions.

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
Solubility: ≥ 2.5 mg/mL (7.39 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.39 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
