LT052 (1 μM) inhibits NF-κB transcriptional activity in HUVECs cells and inhibit nitric oxide (NO) production (inhibition rate: 101.89%) in RAW264.7 cells. In the evaluation of in vitro inflammatory activity, LT052 maintains comparable or better anti-inflammatory activity than the pan-BET inhibitor (JQ1) compared to the protein weak activity[1].LT052 displays the highinhibitory activity against BRD4(1) (IC50: 87.7±4.9 nM), BRD3(1) (IC50: 246.3±20.2 nM), and BRDT(1) (IC50: 357.1±8.3 nM). LT052 also has inhibitory activities against BRPF1b (IC50: 567.5±16.9 nM). Additionlly, LT052 shows a 238-fold selectivity toward BD1 over BD2 with Kd of 105 nM and >25 μM for BD1 and BD2, respectively[1].LT052 (1 μM; 1 hour) inhibits MSU-induced pyroptosis of THP-1 cells through BRD4/NF-κB/NLRP3 signaling pathways[1].

LT052 suppresses pyroptosis of macrophages in rat synovial tissues through regulating BRD4/NF-κB/NLRP3 signaling pathway[1].
LT052 has a high clearance rate in the range of 93.517 μL/min/mg proteins to 146.685 μL/min/mg proteins in liver microsomes of multiple species (human, monkey, dog, rat). Overall, LT052 exhibits moderately stable levels of in vitro liver microsomal metabolism[1].
