The present invention provides a class of chemical compounds useful as efficacious drugs in the treatment of sickle cell disease and diseases characterized by unwanted or abnormal cell proliferation. The active compounds are substituted triaryl methane compounds or analogues thereof where one or more of the aryl groups is replaced with a heteroaryl, cycloalkyl or heterocycloalkyl group and/or the tertiary carbon atom is replaced with a different atom such as Si, Ge, N or P. The compounds inhibit mammalian cell proliferation, inhibit the Gardos channel of erythrocytes, reduce sickle erythrocyte dehydration and/or delay the occurrence of erythrocyte sickling or deformation.
本发明提供了一类化合物,可作为治疗镰状细胞病和以不需要或异常细胞增殖为特征的疾病的有效药物。这些活性化合物是取代的三芳基甲烷化合物或其类似物,其中芳基中的一个或多个被取代为杂芳基、环烷基或杂环烷基,或者第三级碳原子被硅、锗、氮或磷等不同的原子取代。这些化合物抑制哺乳动物细胞的增殖,抑制红细胞的Gardos通道,减少镰状红细胞的脱水,延迟红细胞的镰刀变形或变形的发生。
