CCT373567

CCT373567 is a non-degrading isomer of the BCL6 degrader CCT373566 (HY-146185). CCT373567 acts as a BCL6 inhibitor with an IC₅₀ of 2.9 nM. CCT373567 exerts growth inhibitory activity against cancer cells expressing BCL6, but shows low activity against cancer cells with low BCL6 expression. CCT373567 can be used in research related to diffuse large B-cell lymphoma.

In Vitro

CCT373567 potently inhibits BCL6 BTB domain-corepressor interactions in a cell-free TR-FRET assay with an IC₅₀ of 2.9 nM^[1].
CCT373567 fails to induce meaningful BCL6 degradation in OCI-Ly1 cells, with a DC₅₀ >2000 nM and a maximum degradation of >30%^[1].
CCT373567 inhibits proliferation of BCL6-expressing diffuse large B-cell lymphoma cell lines (OCI-Ly1, Karpas 422, HT, SU-DHL-4) with GI₅₀ values ranging from 38 nM to 820 nM, and shows weak activity against low BCL6-expressing OCI-Ly3 cells with a GI₅₀ of 2145 nM^[1].

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.
