葡萄糖调节蛋白94(Grp94)是90 kDa热休克蛋白(Hsp90)家族的内质网(ER)常驻同工型,其抑制作用代表了治疗许多疾病的有希望的治疗靶标。修改第一代顺式酰胺生物同工甾醇咪唑,通过顺式酰胺替代来改变间苯二酚环与苄基侧链之间的夹角,从而制得了具有改善的Grp94亲和力和选择性的化合物。结构-活性关系研究导致发现化合物30,该化合物表现为540 n m对Grp94的亲和力和73倍的选择性。Grp94负责与细胞信号传导和运动相关的蛋白质(包括选定的整联蛋白)的成熟和运输。研究表明,Grp94选择性抑制剂30对多种侵袭性和转移性癌症表现出有效的抗迁移作用。

The first direct synthesis of substituted anthracenes from o-tolualdehydes and aryl iodides via a Pd(II)-catalyzed CH arylation using an alcohol-bearing transient directing group and subsequent AgOTf-assisted electrophilic aromatic cyclization is described. New transient directing groups consisting of amino acids and amino alcohols enhanced the reactivity, and the CH arylation was complete in 12 h

Abstract Reported herein is the first example of heterogeneous palladium catalyzed C(sp3)-H bonds arylation by a transient-ligand-directed strategy. Using supported palladium (metallic state) nanopariticles as catalyst, a wide range of aryl iodides undergo the coupling with various o-methylbenzaldehyde derivatives to assemble a library of highly selective and functionalized o-benzylbenzaldehydes. The
