The present invention provides novel nucleoside and nucleotide derivatives that are useful agonists or antagonists of P1 or P2 receptors. For example, the present invention provides a compound of formula A-M, wherein A is modified adenine or uracil and M is a constrained cycloalkyl group. The adenine or uracil is bonded to the constrained cycloakyl group. The compounds of the present invention are useful in the treatment or prevention of various diseases including airway diseases (through A
2B
, A
3
, P2Y
2
receptors), cancer (through A
3
, P2 receptors), cardiac arrhythmias (through A
1
receptors), cardiac ischemia (through A
1
, A
3
receptors), epilepsy (through A
1
, P2X receptors), and Huntington's Disease (through A
2A
receptors).
本发明提供了新型的核苷酸和核苷酸衍生物,它们是P1或P2受体的有用的激动剂或拮抗剂。例如,本发明提供了一个式为A-M的化合物,其中A是修饰过的腺嘌呤或尿嘧啶,M是一个约束的环烷基团。腺嘌呤或尿嘧啶与约束的环烷基团相结合。本发明的化合物在治疗或预防各种疾病方面是有用的,包括空气道疾病(通过A2B,A3,P2Y2受体),癌症(通过A3,P2受体),心律失常(通过A1受体),心肌缺血(通过A1,A3受体),癫痫(通过A1,P2X受体)和亨廷顿病(通过A2A受体)。
