Charged and neutral small fluorescent molecules based upon the styryl scaffold are useful as imaging agents for misfolded proteins such as amyloid plaque. Charged molecules are prepared using pyrrolidine catalyzed reactions by solution-phase synthesis. Neutral styryl molecules are prepared using acetic anhydride catalyzed reactions, Horner-Emmons reactions or Wittig reactions.

Amphiphilic Cyanine-Platinum Conjugates as Fluorescent Nanodrugs
Two fluorescent nanomedicines based on small molecular cyanine–platinumconjugates have been prepared via a nanoprecipitation method and characterized by transmission electron microscopy (TEM) as well as dynamic light scattering (DLS). The conjugates exhibited an enhanced fluorescence in their nanoparticle formulation compared to that in solution. The nanomedicines could be endocytosed by cancer cells
