Patent ID: 8623897

Claim:
A composition comprising at least one compound according to Formula I: its stereoisomers and/or pharmaceutically acceptable salts, wherein: R 1 is selected from a group consisting of hydroxy, alkoxy, amine, alkyl, haloalkyl, NHSO 2 R, or NHCOR wherein R is selected from alkyl or cycloalkyl, NHR′ wherein R′ is alkyl or cycloalkyl optionally substituted by hydroxy or alkoxy; n 1 and n 2 are independently selected from 0, 1, and 2; at least one of R 3 and R 4 and/or R 5 and R 6 form a cyclic ring of 3-8 carbon atoms optionally containing alkyl groups, hetero atoms, or functional groups such as O, N, SO 2 ; R 3 and R 4 or R 5 and R 6 , when they do not form a cyclic ring, are independently selected from hydrogen, alkyl, branched alkyl, and cycloalkyl; L 1 is a linear aliphatic chain optionally containing from 4 to 16 carbon atoms, optionally substituted one or more times by alkyl, branched alkyl, cycloalkyl, or aryl; R 2 is independently selected from hydrogen, alkoxy, hydroxy, alkyl, haloalkyl, cycloalkyl, heterocycloalkyl, heteroaryl, cyano, or COR 7 , wherein R 7 is selected from hydroxy, alkyl, alkoxy, or amine, NHR′, NHSO 2 R, or NHCOR; Y 1 is oxygen or hydrogen; Y 2 is optional, and wherein when Y 2 is present, Y 1 and Y 2 are hydrogen and when Y 2 is not present, Y 1 forms a carbonyl group.
