ZrOCl2·8H2O catalyzed environmentally benign synthesis of isobenzofuran-1(3H)-ones are described. ZrOCl2·8H2O appeared to be an excellent catalyst for the condensation and reactions. Reaction of phthalaldehydicacid (2-carboxybenzaldehyde) with methylaryl and cyclic ketones was initiated by condensation and occurred in one step providing excellent yields (90–98%).

Aicardi-Goutières syndrome demonstrate that ablating the cyclicGMP-AMPsynthase gene abolishes the deleterious phenotype. Here, we report the discovery of a class of cyclicGMP-AMPsynthase inhibitors identified by a high-throughput screen. These compounds possess defined structure-activity relationships and we present crystal structures of cyclicGMP-AMPsynthase, double-stranded DNA, and inhibitors within the enzymatic
环状 GMP-AMP 合酶对于抵抗感染和细胞损伤的先天免疫至关重要,可作为病原体 DNA 或错误定位的自身 DNA 的传感器。结合双链 DNA 后,环状 GMP-AMP 合酶会合成环状二核苷酸,引发炎症细胞反应。小鼠研究概括了自身免疫性疾病 Aicardi-Goutières 综合征的致病突变,表明消除环 GMP-AMP 合酶基因可以消除有害的表型。在这里,我们报告了通过高通量筛选鉴定出的一类环 GMP-AMP 合酶抑制剂的发现。这些化合物具有明确的结构-活性关系,我们在酶活性位点内展示了环 GMP-AMP 合酶、双链 DNA 和抑制剂的晶体结构。我们发现化学改良的成员 RU.521 在环 GMP-AMP 合酶介导的信号传导的细胞测定中具有活性和选择性,并减少 Aicardi-Goutières 综合征小鼠模型巨噬细胞中干扰素的组成型表达。 RU.521 将有助于了解环 GMP-AMP 合
