The present invention provides a compound of formula (I) or its salts or pharmaceutically acceptable derivatives thereof wherein; X1 is selected from a group consisting of CH, O or N; R1 is selected from the group consisting of optionally substituted arylalkyl, and optionally substituted heteroarylalkyl; R2 is selected from the group consisting of optionally substituted aryl, optionally substituted heteroaryl or NR6R7; R3 is selected from the group consisting of hydrogen, halogen, hydroxyl, alkoxy, aryloxy, optionally substituted alkyl, optionally substituted amino, optionally substituted amino sulphonyl or nitrile; R4 is selected from the group consisting of optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted heterocycloalkyl, optionally substituted acyl, optionally substituted sulfonyl, optionally substituted sulfamoyl, optionally substituted aryl, optionally substituted arylalkyl, and optionally substituted heteroaryl R5 may be hydrogen or may, together with R4 and X1 (when X1= N), form an optionally substituted saturated or partially saturated 5-7 membered ring with the general formula (II). X2 is C(=O), C(R8)2; X3 is, C(R9)2, N(R9b), O or S; R6 and R7 are the same or different and each represents hydrogen, optioanally substituted alkyl, optionally substituted cycloalkyl, optionally substituted arylalkyl, optionally substituted aryl or optionally substituted heteroaryl; R8a and R8bfor each occurence is independently hydrogen, halogen, optionally substituted amino, optionally substituted amino carbonyl, hydroxyl, optionally substituted acyl, optionally substituted alkoxy, optionally substituted aryloxy, optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted arylalky, optionally substituted aryl or optionally substituted heteroaryl; R9a R9b for each occurence is independently hydrogen, halogen, optionally substituted amino, optionally substituted amino carbonyl, hydroxyl, optionally substituted acyl, optionally substituted alkoxy, optionally substituted aryloxy, optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted arylalky, optionally substituted aryl or optionally substituted heteroaryl; R9c is optionally substituted acyl, optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted arylalky, optionally substituted aryl or optionally substituted heteroaryl; With the proviso that: When X1 is O then j = 0 When X1 is N or CH then j =1 n = 1,2 or 3. The compounds are useful as potassium ion channel inhibitors.
