Synthesis of 2-Aryl-1,2-dihydrophthalazines via Reaction of 2-(Bromomethyl)benzaldehydes with Arylhydrazines
摘要:
The reaction of 2-(bromomethyl)benzaldehydes with arylhydrazines employing K2CO3 as a base and FeCl3 as a catalyst in CH3CN at 100 degrees C delivers 2-aryl-1,2-dihydrophthalazines with yields ranging from 60 to 91%. The transformation is considered to proceed as an intermolecular condensation/intramolecular nucleophilic substitution.

highly potent, orally available, and brain-penetrating RIP1 kinase inhibitor with excellent PK profiles. Compound 22 significantly suppressed necroptotic cell death both in mouse and human cells. Oral administration of 22 (10 mg/kg, bid) attenuated disease progression in the mouseexperimentalautoimmuneencephalomyelitis (EAE) model of multiple sclerosis (MS). Moreover, analysis of structure–kinetic
我们报告发现7-oxo-2,4,5,7-四氢-6 H-吡唑并[3,4- c ]吡啶衍生物作为一种新型的受体相互作用蛋白1(RIP1)激酶抑制剂。在HTS命中10与RIP1激酶的GSK2982772(6)之间的叠加研究的基础上,我们设计并合成了具有中度RIP1激酶抑制活性和P-gp介导外排的新型RIP1激酶抑制剂11。核心结构的优化和利用SBDD方法探索适当取代基的发现导致发现22,一种具有出色PK谱的高效,口服,可穿透脑的RIP1激酶抑制剂。化合物22显着抑制小鼠和人类细胞中的坏死性细胞死亡。在多发性硬化症(MS)小鼠实验性自身免疫性脑脊髓炎(EAE)模型中,口服22(10 mg / kg,bid)的剂量可减轻疾病的进展。此外,还讨论了我们新化学系列的结构动力学关系(SKR)分析。
