Aminoalkyl phenyl sulfones--a novel series of 5-HT7 receptor ligands.

abstract：:A number of analogues of the recently described compound nematophin were prepared and studied for antibacterial activity. The 2-phenyl derivative was found to exhibit exceptional activity against methicillin resistant Staphylococcus aureus (MRSA) whereas the isosteric benzimidazole analogue was much less active. ...
