Page/Page column 115, (2011/09/19)
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.
