A first aspect of the invention relates to a compound of formula (I), or a pharmaceutically acceptable salt or ester thereof, wherein: R1 is -NR3R4 or -OR5; R2 is selected from aryl, heteroaryl, fused aryl- heterocycloalkyl and fused heteroaryl-heterocycloalkyl each of which may be optionally substituted by one or more R8 groups; R3 is H or alkyl; R4 is: (i) cycloalkyl optionally substituted by one or more -NR11R12, -NHCO2R11, -NHCOR11 and -NHSO2R11 groups; or (ii) -(CH2)n-heterocycloalkyl, wherein said heterocycloalkyl is a 4, 5 or 6-membered nitrogen-containing group optionally containing one or more CO groups, wherein said heterocycloalkyl is optionally substituted by one or more one or more (CH2)nR7 groups; (iii) -(CH2)n-heteroaryl, wherein said heteroaryl group is optionally substituted by one or more R7 groups; or (iv) alkyl substituted by one or more -NR11R12groups; or R3 and R4 are linked together with the nitrogen to which they are attached to form a 4, 5 or 6-membered heterocycloalkyl group optionally containing one or two further groups selected from CO, O, N and S, and which is optionally further substituted by one or more R7 groups; R5 is selected from alkyl, -(CH2)n-heteroaryl and -(CH2)n-heterocycloalkyl, wherein said heteroaryl and heterocycloalkyl groups are each optionally substituted by one or more R7 groups; each R11 and R12 is independently H or alkyl; and each n is independently an integer from O to 6; for use in treating or preventing a disorder associated with CDPK. Further aspects relate to the use of said compounds in the treatment of various therapeutic disorders, and more particularly as inhibitors of PfCDPK1.
发明的第一个方面涉及式(I)的化合物,或其药学上可接受的盐或酯,其中:R1为-NR3R4或-OR5;R2选自芳基、杂环芳基、融合芳基-杂环烷基和融合杂环芳基-杂环烷基,每种基可能被一个或多个R8基取代;R3为H或烷基;R4为:(i) 可选地被一个或多个-NR11R12、-NHCO2R11、-NHCOR11和-NHSO2R11基取代的环烷基;或(ii) -(CH2)n-杂环烷基,其中所述杂环烷基是一个含氮的4、5或6成员环基,可选地含有一个或多个CO基团,其中所述杂环烷基可被一个或多个(CH2)nR7基团取代;(iii) -(CH2)n-杂芳基,其中所述杂芳基可被一个或多个R7基团取代;或(iv) 被一个或多个-NR11R12基团取代的烷基;或R3和R4与它们连接到的氮一起形成一个含有一个或两个进一步选择自CO、O、N和S的4、5或6成员杂环烷基基团,可选地进一步被一个或多个R7基团取代;R5选自烷基、-(CH2)n-杂芳基和-(CH2)n-杂环烷基,其中所述杂芳基和杂环烷基基团可选地被一个或多个R7基团取代;每个R11和R12独立地为H或烷基;每个n独立地为0到6的整数;用于治疗或预防与CDPK相关的疾病。进一步方面涉及所述化合物在治疗各种治疗性疾病中的使用,更特别地作为PfCDPK1的抑制剂。
