Patent ID: 7968548

Claim:
A compound having the formula of structure I: or an enantiomer, stereoisomer or diastereoisomer thereof, or a pharmaceutically acceptable salt thereof, wherein J is a ring structure selected from the group consisting of substituted or unsubstituted aromatic carbocyclic rings, substituted or unsubstituted aromatic fused carbobicyclic ring groups, or two substituted or unsubstituted aromatic carbocyclic rings wherein the rings are joined by a bond, —CH 2 —, or —O—, wherein in each instance the ring attached to L 1 has 6 ring atoms; W is a diamine heteroatom unit with at least one cationic center, hydrogen bond donor or hydrogen bond acceptor; Q is an aromatic carbocyclic ring selected from the group consisting of phenyl, substituted phenyl, naphthyl and substituted naphthyl; L 1 is —C(═O)—CH(N(R 10a R 10b ))—CH 2 —; L 2 is a bond or —(CH 2 ) z —; L 3 is —C(═O)—CH(N(R 10a R 10b ))—CH 2 —; one or two of R 1a , R 1b , R 2a , and R 2b are independently a C 1 to C 6 aliphatic linear or branched chain and the remaining of R 1a , R 1b , R 2a , and R 2b are hydrogen, provided that at least one of R 1a and R 1b and at least one of R 2a and R 2b are hydrogen; or one of R 1a , R 1b , R 2a , and R 2b are and the remaining of R 1a , R 1b , R 2a , and R 2b are hydrogen; or R 1a and R 1b together form ═O and one of R 2a and R 2b is a C 1 to C 6 aliphatic linear or branched chain, and the remaining of R 2a and R 2b is hydrogen; each occurrence of R 10a and R 10b is independently hydrogen, acetyl, methyl, ethyl, propyl, isopropyl, butyl, pentyl, hexyl, isobutyl, benzyl, benzoyl, hexanoyl, propionyl, butanoyl, pentanoyl, heptanoyl, cyclopropyl, cyclopropylmethyl, cyclobutyl, cyclobutylmethyl, cyclohexyl, cyclohexylmethyl, or polyethylene glycol; X is CH 2 , C═O or C═S; z is an index value from 1 to 6; and y is an index value from 0 to 5; wherein the carbon atom marked with an asterisk can have any stereochemical configuration.
