Article Synopsis
  • * A new compound, [F]fluoroethyltriazolyl substituted senicapoc, was tested as a PET tracer and showed promising results for imaging the K 3.1 channels in lung cancer cells in animal studies.
  • * Novel senicapoc BODIPY conjugates have been developed for visualizing K 3.1 channels; these compounds demonstrate strong specificity and improved solubility, confirmed by binding studies with the channel structure.
