Calix[4]arenesbearing acridinium and acridane substituents at the wide rim and a short glycol chain and two OH-groups at the narrow rim have been prepared. The interaction with alkali metalions can be identified with the naked eye by the change in solution color arising from deprotonation of the OH-groups. Unlike the acridane calixarenes, the acridinium-substituted calixarene-crown-4 binds sodium

We previously reported the antibacterial activity of CD437, a known antitumor compound. It proved to be a potent antimicrobial agent effective against both growing and persister cells of methicillin-resistant Staphylococcus aureus (MRSA). Herein, we report the synthesis of a panel of analogs and their effect on both MRSA and cancer cells. The hydrophobic group of the parent compound was varied in steric bulk, and lipid-mimicking analogs were tested. Biological assessment confirmed that the adamantane moiety is the most effective substitution for antibacterial activity, and some preferential action in cancer over MRSA was achieved.
