MLT-943

产品介绍

MLT-943 是一种有效的、选择性的、口服活性的 MALT1 protease 抑制剂。MLT-943 可抑制 PBMC 或全血中 IL-2 的分泌，PBMC 中抑制的 IC₅₀ 值为 0.07~0.09 μM，全血中抑制的 IC₅₀ 值为 0.6~0.8 μM)。MLT-943具有抗炎活性，可用于 FcgR 介导的炎症研究。

生物活性

MLT-943 is a potent, selective and orally active MALT1 protease inhibitor. MLT-943 inhibits stimulated-IL-2 secretion in PBMC or in whole blood with a similar IC₅₀ across species (0.07-0.09 μM in PBMC, 0.6-0.8 μM in whole blood). MLT-943 has anti-inflammatory activities and can be used for FcgR-mediated inflammation research.

体外研究

MLT-943 shows a high potency and selectivity in vitro. MLT-943 inhibits stimulated IL-2 secretion in PBMC or in whole blood with a similar IC₅₀ across species (0.07-0.09 μM in PBMC, 0.6-0.8 μM in whole blood).

体内研究

MLT-943 (oral gavage; 10 mg/kg; QD) prophylactic treatment in the rat collagen-induced arthritis model suppresses anti-collagen antibody production, fully prevents paw swelling, and normalizes joint histology scores in rat model.
MLT-943 (oral gavage; 5 mg/kg; QD; 10 consecutive days) effectively inhibits MALT1 protease activity and results in a progressive reduction in the frequency of Foxp³⁺CD25⁺ Treg cells in circulating CD4⁺ T cells, which was maximal after 7 days of treatment. And Discontinuation of MLT-943 treatment after day 10 leads to Treg frequency progressively returning to their original values within 4 days. Suboptimal doses of MLT-943 (0.1 and 0.5 mg/kg QD; p.o.) does not impact the Treg frequency.
MLT-943 (oral gavage; 0, 5, 20 or 80 mg/kg/day; 4-13 weeks) causes a reduction in Treg and an increase in total T cell counts, in both 4- and 13-week rat toxicity studies at all dose levels. While a 4-Longer treatment induces severe immune-mediated pathology in multiple organs, with clinical onset starting around week 9 in rat.
MLT-943 (p.o. admistration; 3 mg/kg; single dose) exhibits a good PK parameters in vivo. The C_max values are 0.7 nM and 0.5 nM, respectively in rat and mice, respectively. And the F% are 86% and 50% in rat and mice, respective.
For i.v. admistration the compound is formed in NMP:PEG200 (30/70); For p.o. admistration solution is formed in MC:Tween 80:Water (0.5:0.5:99) solution (Sourced from literature, for reference only).
