生物活性:
CID5721353 is an inhibitor of BCL6 with an IC50 value of 212 μM, which corresponds to a Ki of 147 μM.
体内研究:
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 gradually over 24 hours.
体外研究:
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.
