Sphingosine kinases are enzymes that catalyze the biosynthesis of sphingosine-1-phosphate. The invention provides compounds that are effective for inhibition of sphingosine kinase type 1, sphingosine kinase type 2, or both. Certain compounds are selective for sphingosine kinase type 2 relative to sphingosine kinase type 1. Compounds of the invention can be used in treatment of a range of diseases wherein increasing the level of sphingosine-1-phosphate in blood is medically indicated. Diseases that can be treated by administration of an effective dose of a compound of the invention include a neoplastic disease that involves excess vascular growth; macular degeneration or diabetic retinopathy; an allergic disease such as asthma, an inflammatory disease of the eye such as uveitis, scleritis, or vitritis; an inflammatory disease of the kidney; a fibrotic disease; atherosclerosis; or pulmonary arterial hypertension. A compound of the invention can be used to improve the integrity of a vascular barrier in a disease where the vascular barrier is disrupted, such as cancer or Alzheimer's disease.
鞘氨醇激酶是催化 1-磷酸鞘氨醇生物合成的酶。本发明提供的化合物可有效抑制鞘氨醇激酶 1 型、鞘氨醇激酶 2 型或两者。相对于 1 型鞘氨醇激酶,某些化合物对 2 型鞘氨醇激酶具有选择性。本发明的化合物可用于治疗一系列疾病,在这些疾病中,提高血液中鞘磷脂-1-磷酸的水平具有医学意义。可通过施用有效剂量的本发明化合物治疗的疾病包括:涉及血管过度生长的肿瘤性疾病;黄斑变性或糖尿病视网膜病变;过敏性疾病,如哮喘;眼部炎症性疾病,如葡萄膜炎、巩膜炎或玻璃体炎;肾脏炎症性疾病;纤维化疾病;动脉粥样硬化;或肺动脉高压。本发明的化合物可用于改善血管屏障被破坏的疾病(如癌症或阿尔茨海默病)中血管屏障的完整性。
