A compound (including its salts) according to Formula I wherein R1 is H, methyl or ethyl; R2 is H, OH, fluorine, linear or branched C1-C4 alkyl, C1-C6 alkoxy wherein the alkyl group is linear or branched, or a C3-C5 R3 cycloalkyl moiety is H, methoxy, methyl or ethyl; or R2 and R3 together form a combined fraction -O-CH2- O- between the phenyl carbon atoms to which they are connected; R4 is OH or methoxy; and R5 and R6 are independently selected from H or methyl; R1, R2, R3, R4, R5 and R6 are such that, (i) when R2 and R3 together form a combined fraction of -O-CH2-O- between the phenyl carbon atoms to which they are connected, R1 , R5, R6 are H, and R4 is OH; and (chi) when R4 is OH and R1-R3 are H, at least one of R5, R6 is methyl. |
