Claim:
A compound of Formula I, or a pharmaceutically acceptable salt thereof, wherein: E and G are each independently selected from the group consisting of C 1-4 alkyl, —NH—, —N(C 1-4 alkyl)-, —O— and, in either orientation, —NH—C 1-4 alkyl-, —N(C 1-4 alkyl)-C 1-4 alkyl-, and —O—C 1-4 alkyl-; and is a single bond; when is a single bond, K is independently selected from CH and N, and J is independently selected from NH and CH 2 ; or R 1 and R 2 are each 0-2 substituents wherein each substituent is independently selected from the group consisting of —C 1-4 alkyl, —OH, —O—C 1-4 alkyl, N(R 4 ) 2 , C 1-4 alkylN(R 4 ) 2 , NO 2 , halogen, and CF 3 ; each R 4 is independently selected from the group consisting of H, OH, —C 1-4 alkyl, —C(O)OC 1-4 alkyl, and —C(O)R 5 , provided that if one R 4 is OH then the other R 4 cannot be OH; or —N(R 4 ) 2 forms a pyrrolidinyl, piperidinyl, piperazinyl, or morpholino group optionally substituted methyl; R 5 is selected from the group consisting of —C 1-4 alkyl and phenyl; and R 3 is selected from the group consisting of H, —C 1-4 alkyl, aryl, and alkylaryl.
