T2AA is a small molecule inhibitor of PCNA/PIP-box interactions, which suppresses translesion DNA synthesis.
T2AA hydrochloride has been used as a chemical inhibitor of proliferating cell nuclear antigen (PCNA) in vaccinia virus.
T2AA is an inhibitor of PCNA/ PIP-Box interactions that binds to the PCNA cavity that interacts with PIP-Box sequences. Also T2AA inhibits PCNA Polδ3 interaction. T2AA inhibits de novo DNA synthesis, and in combination of cisplatin significantly increases growth inhibition in cancer cells. T2AA is a T3 analog that exhibits almost no thyroid hormone activity.
