Patent ID: 7501404

Claim:
A compound according to the following structure: wherein A is a member selected from CR 1 R 2 , O and S wherein R 1 is H, R 2 is H, B is a member independently selected from unsubstituted alkyl, —S—, and —O—; m is an integer selected from 0 to 2; C is a member selected from a bond and —O—; D is a member selected from X is a member selected from S and O; Y is a member selected from a bond, C═O, and SO 2 ; R a is a member selected from NR 7 R 8 and substituted and unsubstituted heteroaryl wherein R 7 is a member selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl; and R 8 is a member selected from substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl; R c is a member selected from H and substituted or unsubstituted alkyl; R d is a member selected from R 16 and (CR 14 R 15 ) p R 16 wherein p is 1; R 14 is H; R 15 is H; and R 16 is a member selected from C(O)R 18 , OH, and wherein R 18 is a member from OR 21 , NR 19 R 20 , and NR 19 SO 2 R 20 wherein R 21 is a member selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, and substituted or unsubstituted aryl; R 19 is a member selected from H and substituted or unsubstituted alkyl; and R 20 is a member selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl; and R 19 and R 20 can be optionally joined, together with the atoms to which they are attached, to form a 6 membered ring; and R d is H; with the proviso for the compound, or salts thereof, that if: Y is a member selected from C═O and SO 2 ; ABC, in combination, form unsubstituted alkyl; and D is substituted or unsubstituted guanidine; then R c cannot be a member selected from CH 3 and CH 2 CH 3 ; and R d and R d ′ cannot be members selected from H and COOR 1a ; and H and CONR 19 R 20 ; wherein R 1a is a member independently selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, and substituted or unsubstituted aryl; R 19 is selected from H and substituted or unsubstituted alkyl; and R 20 is selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl.
