The present invention relates to sphingosine-1-phosphate (S1P) receptors and compounds of the general formula:
that are useful in the treatment and prevention of conditions associated with such receptors. More specifically, the present invention relates to the synthesis and use of sphingosine 1-phosphate receptor 2 (S1P
2
) antagonists that are useful in the treatment of cancer, atherosclerosis, diabetic retinopathy, and other inflammatory diseases. Among these inflammatory diseases that could be treated with these S1P
2
antagonist are those characterized by fibrosis including chronic lung disease, chronic kidney and liver disease, chronic heart disease, and skin diseases such as sclerosis/scleroderma. The S1P
2
antagonists can also be used in the treatment of glioblastoma multiforme (brain cancer), pediatric neuroblastoma, and other cancers.
本发明涉及
鞘氨醇-1-
磷酸(S1P)受体和下列通式的化合物:
这些化合物在治疗和预防与此类受体相关的疾病方面是有用的。更具体地,本发明涉及合成和使用
鞘氨醇1-
磷酸受体2(S1P2)拮抗剂,这些拮抗剂在治疗癌症、动脉硬化、糖尿病视网膜病变和其他炎症性疾病方面是有用的。这些炎症性疾病中,可以用这些S1P2拮抗剂治疗那些以纤维化为特征的疾病,包括慢性肺病、慢性肾脏和肝脏疾病、慢性心脏病以及硬化/硬皮病等皮肤疾病。S1P2拮抗剂还可以用于治疗多形性胶质母细胞瘤(脑癌)、儿童神经母细胞瘤和其他癌症。
