Doramapimod (BIRB 796) 是一种具有口服活性的,高效的p38 MAPK抑制剂,IC50值分别为 p38α=38 nM,p38β=65 nM,p38γ=200 nM,p38δ=520 nM。Doramapimod 对 p38 激酶具有皮摩尔亲和力 (Kd=0.1 nM)。Doramapimod 也抑制B-Raf和 Abl,IC50分别为 83 nM 和 14.6 μM。
生物活性 | Doramapimod (BIRB 796) is an orally active, highly potentp38 MAPKinhibitor, which has anIC50for p38α=38 nM, for p38β=65 nM, for p38γ=200 nM, and for p38δ=520 nM. Doramapimod has picomolar affinity for p38 kinase (Kd=0.1 nM). Doramapimod also inhibitsB-Rafwith anIC50of 83 nM[1][2]. |

体外研究 (In Vitro) | Doramapimod (BIRB 796) is usually associated with inflammation because of its role in T-cell proliferation and cytokine production[1]. Doramapimod (BIRB 796) blocks the stress-induced phosphorylation of the scaffold protein SAP97, further establishing that this is a physiological substrate of SAPK3/p38γ. The binding of Doramapimod to the p38 MAPKs or JNK1/2 is impairing their phosphorylation by the upstream kinase MKK6 or MKK4[3].

体内研究 (In Vivo) | The mean xenograft weigh of Doramapimod (BIRB 796) is lighter than control. The inhibition rate of Doramapimod is 1.93%[4]. The Doramapimod (BIRB 796) treatment slightly reduces blood pressure (166±7 mm Hg at week 7; P<0.05), whereas SD rats are normotensive (123±3 mm Hg). Despite the reduction in blood pressure, untreated and Doramapimod-treated dTGRs have similar heart weight and cardiac hypertrophy indices (heart-to-tibia ratio), which are significantly higher compare with nontransgenic SD rats (310±6 versus 307±6 versus 206±5 mg/cm, respectively; P<0.05)[5].
