产品介绍

Pamapimod (Ro4402257) 是一种有效的，选择性和口服活性的p38 MAPK抑制剂，对于p38α和p38β的IC₅₀分别为 14 nM 和 480 nM，K_i分别为 1.3 nM 和 120 nM。Pamapimod 对 p38δ 或 p38γ 亚型没有活性。Pamapimod 可用于类风湿关节炎和其他自身免疫性疾病的研究。

生物活性

Pamapimod (Ro4402257) is a potent, selective and orally activep38 MAPKinhibitor withIC₅₀s of 14 nM and 480 nM andK_is of 1.3 nM and 120 nM forp38αandp38β, respectively. Pamapimod has no activity againstp38δorp38γisoforms. Pamapimod has the potential for rheumatoid arthritis and other autoimmune diseases treatment^[1].

体外研究
(In Vitro)

Pamapimod binds to JNK kinases with K_ivalues of 190 nM, 16 nM and 19 nM for Jnk1, Jnk2 and Jnk3, respectively^[1].
After lipopolysaccharide (LPS) stimulation of the human myelomonocytic cell line (THP-1), secretion of TNF-α is inhibited by Pamapimod, with an EC₅₀of 25 nM. Pamapimod suppresses TNF-α and IL-1β production in whole blood, with EC₅₀values of 0.40 and 0.10 μM, respectively^[1].
