    • The present invention provides a genus of polycyclic pyrazines of formula I (I) that are useful as modulators of potassium ion channels. The modulators of the invention are of use in both therapeutic and diagnostic methods; wherein A and B are independently substituted or unsubstituted 5- or 6-membered heterocycloalkyl, or substituted or unsubstituted 5- or 6- membered heteroaryl, W1 is formula II (II); W2 is -CH=, -NH-, -N=, -S-, or -O-; Z1 is formula III (III) or formula IV (IV); Z2 is -CH=, -NH-, -N=, -S-, or -O-; Y is a bond, -CH=N-NH-, -NH-CH2-, or -NR5-; s and t are independently integers fr om 1 to 4; R1, R2A, R2B and R3 are independently or unsubstituted alkyle, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl , substituted or unsubstituted 3- to 7- membered cycloalkyl,, substituted or unsubstituted 5- to 7-membered heterocycloalkyl, substituted or unsubstitute d aryl, or substituted or unsubstituted heteroaryl; and R5 is H, substituted o r unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted o r unsubstituted 3- to 7- membered cycloalkyl,, substituted or unsubstituted 5- to 7-membered heterocycloalkyl, substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl; wherein if s is greater than one, then each R1 is optionally different; wherein if t is greater than on, then each R3 is optionally different; wherein two R1 groups are optionally joined together with the atoms to which they are attached to form a substituted or unsubstituted ring; and wherein two R3 groups are optionally joined together with the atoms to which they are attached to form a susbtituted or unsubstituted ring.
