    “…[Image: see text] The targeted introduction of substituents in order to tailor a molecule’s pharmacologic, physicochemical, and metabolic properties has long been of interest to medicinal chemists. The all-cis tetrafluorocyclohexyl motif—dubbed Janus face, due to its electrostatically polarized cyclohexyl ring—represents one such example where chemists might incorporate a metabolically stable, polar, lipocompatible motif. …”

    “…The question of whether there are any bad molecules then leads me to ethical concerns in chemistry, and a particular working out of these in interactions of chemists in the Middle East. An analysis is made of the special tensions involved in publishing, especially in citation ethics; chemists publish a lot, so this is situation ethics worked out on a daily basis. …”
