BCL6 is a member of the BTB/POZ family of transcription factors. CID5721353 (Compound 79-6) specifically inhibits BCL6 repressor activity. CID5721353 disrupts BCL6 transcriptional complexes and reactivates BCL6 target genes. CID5721353 can specifically kill primary human DLBCL cells. Fifteen of 19 BCL6-positive cases (79%) display greater than 25% loss of viability in response to CID5721353 at 125 or 250 μM. has not independently confirmed the accuracy of these methods. They are for reference only.

In order to test whether CID5721353 (Compound 79-6) can perform as an anti-lymphoma therapeutic agent in vivo, whether it can penetrate tumors after parenteral administration through a distal site is determined. For this purpose 107OCI-Ly7 cells are injected into the right flank of 10 SCID mice and allowed to form tumors. Once tumors reach ~1.5 grams, animals are injected IP with a single dose of 50 mg/kg of CID5721353 in 10% DMSO or vehicle (10% DMSO) and sacrificed at 0.5, 1, 1.5, 3, 6, 12 and 24 hours after CID5721353 administration. Blood and tumors are harvested. Quantitative HPLC/MS analysis of the serum shows that CID5721353 levels peak (to 55 μg/mL, which is equivalent to a 122 μM concentration) one hour after the IP injection. CID5721353 also reaches its highest peak (24.5 ng/mg) at the 1-hour time point in the tumors, and after a sharp decline in levels, decreases gr
