Syntheses based on dimethylpyrazoles. 9. Synthesis and spectral peculiarities of isomeric pyrazolo[3?,4?-5,6]- and-[5?,4?-5,6]-pyrimido[1,2-b]benzo[d,e]isoquinoline-4,12-diones
从鉴定用于治疗广泛性疾病如炎症,哮喘和帕金森氏病的新药的角度来看,腺苷受体拮抗剂的发现和开发多年来一直代表着一个有吸引力的研究领域。目前的工作可以被认为是我们对吡唑并[4,3- e ] [1,2,4]三唑并[1,5- c ]嘧啶(PTP)核的构效关系研究的扩展,该研究已被广泛研究。我们作为有用的模板,特别是用于鉴定A 2A和A 3腺苷受体拮抗剂。为了探索氮在7位上的作用,我们进行了吡咯并[3,4- e的制备] [1,2,4]三唑并[1,5- c ]嘧啶衍生物,可以将其视为母体PTP的7-脱氮类似物。我们还合成了一系列新颖的吡唑并[3,4- e ] [1,2,4]三唑并[1,5- c ]嘧啶作为参考化合物的连接异构体。在这两种情况下,我们都获得了一些有效的拮抗剂(K i在低纳摩尔范围内)的实例,这些拮抗剂具有与在C 5-,N 8和/或N 9位引入的取代基的性质有关的可变选择性。吡咯并三唑并嘧啶衍生物9b似乎是有效的A
through the activation of NF-κB by interleukin-1 receptor associated kinase 4 (IRAK4) in diffuse large B-cell lymphoma (DLBCL), highlighting IRAK4 as a therapeutic target for tumors driven by aberrant MYD88 signaling. Herein, we report the design, synthesis, and structure-activityrelationships of imidazo[1,2-b]pyridazines as potent IRAK4 inhibitors. The representative compound 5 exhibited excellent

Forkhead box O‐1 (FoxO‐1) is known as a major transcription factor regulating hepatic gluconeogenesis, and the increased FoxO‐1 expression and activity are mainly observed in type 2 diabetic patients. To discover new FoxO‐1inhibitors, the compounds were newly synthesized from decursinol, which is a molecule isolated from the Angelica gigas and proved to be safe. The compounds were evaluated for in vitro
2型糖尿病是由胰岛素抵抗引起的,通常与肝糖异生增加有关。叉头箱O-1(FoxO-1)是调节肝糖异生的主要转录因子,FoxO-1的表达和活性增加主要在2型糖尿病患者中观察到。为了发现新的FoxO-1抑制剂,这些化合物是从地精中新合成的,该分子是从当归中分离出来的分子,被证明是安全的。使用FoxO-1报告基因测定法在HepG2细胞中评估了这些化合物的体外FoxO-1抑制活性。其中,化合物2b和2c对IC 50表现出FoxO-1抑制活性分别为98.9和123.7μM。而且,发现合成化合物2b的降血糖效果与格列美脲类似,后者是可商购的抗糖尿病药,在四氧嘧啶诱发的2型糖尿病大鼠中用作参考(21.6 vs. 21.4%)。这些发现表明,化合物2b对FoxO-1具有中等程度的抑制活性,可能会改善糖尿病性高血糖症。
