“…On the other hand, the higher lipophilicity of 4 among the six active compounds could support it being the only one active against Gram-negative bacteria, since it would be able to permeate cellular membranes more easily. , Considering compound 6 , another symmetric compound such as 4 , one could argue that a longer spacer ( i.e. , more carbon atoms) could still be important for antibacterial activity and thus corroborate the activity of this compound being slightly broader to MRSA strains and consistent against MSSA and MRSA reference strains, when compared to 4 .…”
