BT-O2C is a p300 PROTAC degrader. BT-O2C induces p300 degradation via proteasome- and ubiquitin-like modification-dependent pathways, downregulates the expression of CIC::DUX4 sarcoma target genes, and exerts cytotoxicity against such sarcoma cells. BT-O2C can be used in CIC::DUX4 sarcoma-related studies.

In Vitro

BT-O2C (72 h) exhibits cytotoxicity against the CIC::DUX4 sarcoma cell lines NCC-CDS-X1 and KITRA, with IC₅₀ values of 152 nM and 221 nM respectively after 72 hours of treatment^[1].
BT-O2C (0.1-10 μM; 24-48 h) potently and selectively induces the degradation of p300 in HAP1 cells, and exhibits higher selectivity for p300 degradation over CBP^[1].
BT-O2C (4 μM; 6 h) reduces the expression of CIC::DUX4 target genes ETV1, ETV4 and ETV5 in NCC-CDS-X1 cells, with no statistically significant difference compared with its negative control BT-O2C-N^[1].
BT-O2C (4 μM; 24 h) slightly reduces the acetylation level of H3K27 in NCC-CDS-X1 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (2.57 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
