LT052 是一种高选择性BET BD1抑制剂,其IC50为 87.7 nM。LT052 表现出纳摩尔级别的 BRD4 BD1 的抑制活性,选择性是 BRD4 BD2 的 138 倍 (IC50=12.130 μM)。LT052 具有抗炎活性,可用于急性痛风性关节炎研究。
生物活性

LT052 is a highly selectiveBETBD1inhibitor with anIC50of 87.7 nM. LT052 exhibits nanomolarBRD4BD1 potency and 138-fold selectivity overBRD4BD2 (IC50=12.130 μM). LT052 has anti-inflammatory activity and can be used for acute gout arthritis research[1].

BRD4 BD1

87.7 nM (IC50)

BRD3 BD1

246.3 nM (IC50)

BRDT BD1

357.1 nM (IC50)

BRPF1b

体外研究
(In Vitro)

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 Kdof 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].

体内研究
(In Vivo)

LT052 (1 mg/kg; intra-articular) suppresses synovial hyperplasia as well as severe neutrophil infiltration, and has a good therapeutic effect on MSU-induced acute gouty arthritis[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].

Animal Model:Male Adult Sprague-Dawley rats (250-280 g) (acute gouty arthritis animal models)[1]
Dosage:1 mg/kg
Administration:Intra-articular injection
Result:Restored the joint circumference to normal level.
