Inhibition of intestinal brush border DMT1 offers a novel therapeutic approach to the prevention and treatment of disorders of iron overload. Several series of diaryl and tricyclic benzylisothiourea compounds as novel and potent DMT1 inhibitors were discovered from the original hit compound 1. These compounds demonstrated in vitro potency against DMT1, desirable cell permeability properties and a dose-dependent
抑制肠刷缘DMT1为预防和治疗铁超负荷疾病提供了一种新颖的治疗方法。从最初的化合物1中发现了一些系列的二芳基和三环苄基异硫脲化合物作为新型和有效的DMT1抑制剂。这些化合物在铁超吸收的急性大鼠模型中表现出对DMT1的体外效力,所需的细胞通透性和铁吸收的剂量依赖性抑制。三环化合物将体外效价提高了16倍。二芳基化合物6b和14a在25和50 mg / kg剂量下均显示出明显的体内铁吸收抑制作用。本报告中描述的二芳基和三环化合物代表了有希望的结构模板,可用于进一步优化。
