银屑病是一种常见的免疫介导的皮肤病,表现为皮肤异常斑块,而磷酸二酯酶 4(PDE4)是治疗银屑病等炎症性疾病的有效靶点。Toddacoumalone 是一种天然 PDE4 抑制剂,具有中等效力和不完善的药物样特性。为了发现具有相当成药性的新型强效 PDE4 抑制剂,设计并合成了一系列托达香豆酮衍生物,得到化合物 (2 R ,4 S )-6-ethyl-2-(2-hydroxyethyl)-2,8-dimethyl -4-(2-methylprop-1-en-1-yl)-2,3,4,6-tetrahydro-5 H -pyrano[3,2 - c ][1,8]naphthyridin-5-one ( 33a ) 具有高抑制效力 (IC 50= 3.1 nM)、令人满意的选择性、良好的皮肤渗透性和良好表征的结合机制。令人鼓舞的是, 33a的局部给药在咪喹莫特诱导的银屑病小鼠模型中表现出显着的治疗效果。

potent angiotensin II antagonists. In the pyrimidine carboxylic acid series (W = CR, X = N, Y = CH, Z = COOH), compounds with an alkyl group (R') on the exocyclic nitrogen were much more potent than compounds with an alkyl group (R) on the heterocyclic ring. The corresponding pyridine, pyridazine, pyrazine, and 1,2,4-triazine carboxylic acids also showed potent in vitro angiotensin II antagonism. The pyridine
