the 90 kDa heat shock protein (Hsp90) family and its inhibition represents a promising therapeutic target for the treatment of many diseases. Modification of the first generation cis‐amide bioisostereimidazole to alter the angle between the resorcinol ring and the benzyl side chain via cis‐amide replacements produced compounds with improved Grp94 affinity and selectivity. Structure–activity relationship
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。

A straightforward and efficient method has been developed for the synthesis of 2-benzylbenzaldehyde derivatives from 2-methylbenzaldehyde and iodobenzene via a C(sp3)–H activation process. In the course of the activation reaction, acetohydrazone is formed between 2-benzylbenzaldehyde and acetohydrazine as a transient directing group. As a new kind of transient directing group, acetohydrazone exhibits

Semicarbazide as an effective transientdirectinggroup for C(sp3)−Harylation of 2‐methylbenzaldehydes is described. Various substituted 2‐benzylbenzaldehydes are efficiently synthesized by this strategy. The salient features of this protocol are the use of inexpensive transientdirectinggroup, wide scope of substrates with good functional group compatibility, up to 98% yield, and applicability to
