bmp 4

BMP-4是一种具有抗炎及抗软骨形成功能的穿透肝素结合肽。在小鼠软骨细胞及巨噬细胞实验中，此化合物通过调节iNOS-IFN-IL6信号通路，按剂量依赖方式降低炎症蛋白如iNOS、COX2、IFN与IL6的表达，有效地抑制炎症并减轻多种关节炎症状。

LDN214117 是一种高效的 ALK2 选择性抑制剂(IC50:22nM)，也是一种 BMP6 抑制剂(IC50:100nM)，对ALK5抑制力弱100倍。

BMP signaling agonist sb4 (SB 4) 是苯并恶唑骨形态发生蛋白 4 (BMP4) 信号激动剂(EC50:74 nM)，能够稳定细胞内 p-SMAD-1 5 9 ，激活 BMP 信号。它还能激活典型 BMP 信号通路中的 BMP4 靶基因 (DNA 结合抑制剂，Id1和Id3)。

4-Hydroxychalcone (P-Cinnamoylphenol) 是一种查尔酮代谢物，具有抗血管生成和消炎作用。它抑制 TNF-α 诱导的 NF-κB 途径活化并激活 BMP 信号传导，通过减轻小鼠的醛固酮过多症和肾脏损伤来降低抵抗性高血压。它通过抑制生长因子途径抑制血管生成，无细胞毒性迹象。

Dorsomorphin dihydrochloride (BML-275 2HCl) 是一种 AMPK 抑制剂 (Ki=109 nM)，具有选择性和 ATP 竞争性。Dorsomorphin dihydrochloride 可以抑制 BMP I 型受体 ALK2、ALK3 和 ALK6。Dorsomorphin dihydrochloride 可诱导自噬，具有抗肿瘤活性。

The prostaglandin E receptor 4 (EP4) is one of four G protein-coupled receptors that mediate the actions of prostaglandin E2 . Binding of PGE2 to the EP4 receptor causes an increase in intracellular cyclic AMP, which plays important roles in bone formation and resorption, cancer, and atherosclerosis. KMN-80 is a substituted γ-lactam (pyrrolidinone) derivative of PGE1 that acts as a selective and potent agonist of EP4 with an IC50 value of 3 nM (IC50 = 1.4 μM for EP3 and > 10 μM for all other prostanoid receptors). In functional assays it has been shown to stimulate secreted alkaline phosphatase gene reporter activity in EP4-transfected HEK293 cells with an EC50 value of 0.19 nM, demonstrating >5,000 and 50,000-fold selectivity against EP2 and TP, respectively. KMN-80 can induce the differentiation of bone marrow stem cells from both young and aged rats into osteoblasts in vitro (EC50s = 20 and 153 nM, respectively) and exhibits favorable tolerability up to at least 10 μM, whereas the EP4 agonist L-902,688 is highly cytotoxic at similar concentrations in these cells. KMN-80 has been used to repair calvarial defects in an in vivo rat craniomaxillofacial reconstruction model (rate of reduction in defect size equivalent to BMP-2 treated rats) and to promote bone formation in a rat incisor tooth socket model.

Kirenol (Kirel) 是分离自 Siegesbeckia orientalis 中的，具有抗氧化、抗炎、抗过敏、抗关节炎活性，可用于缓解疼痛的研究。

BUR1 是一种酿酒酵母细胞周期蛋白依赖性激酶 (CDK)，与在转录延伸中起作用的哺乳动物 Cdk9 同源。
