Pharmaceutical Applications of Cyclodextrins. 1. Drug Solubilization and Stabilization

In recent years several review articles and books have been published on the use of porphyrin-based compounds in photodynamic therapy (PDT). This critical review is focused on (i) the basic concept of PDT, (ii) advantages of long-wavelength absorbing photosensitizers (PS), (iii) a brief discussion on recent advances in developing PDT agents, and (iv) the various synthetic strategies designed at the Roswell Park Cancer Institute, Buffalo, for developing highly effective long-wavelength PDT agents and their utility in constructing the conjugates with tumor-imaging and therapeutic potential (Theranostics). The clinical status of certain selected PDT agents is also summarized (205 references).

The present invention provides compositions comprising an anti-angiogenic factor, and a polymeric carrier. Representative examples of anti-angiogenic factors include Anti-Invasive Factor, Retinoic acids and derivatives thereof, and paclitaxel. Also provided are methods for embolizing blood vessels, and eliminating biliary, urethral, esophageal, and tracheal/bronchial obstructions.

Pharmaceutical and Physical Properties of Paclitaxel (Taxol †) Complexes with Cyclodextrins ‡

Taxol (paclitaxel) is a diterpenoid anticancer agent undergoing intensive human clinical evaluation. The poor aqueous solubility of taxol necessitates administration in excipients causing a variety of adverse effects, including anaphylactoid hypersensitivity reactions. Recently, taxol has been formulated in better-tolerated drug carriers such as liposomes. We investigated the conformation of taxol and the interaction of taxol with dipalmitoylphosphatidylcholine (DPPC) liposomes using fluorescence, circular dichroism, differential scanning calorimetry, fluorescence polarization, and X-ray diffraction. The conformation of taxol in DPPC membranes was similar to that observed in nonpolar solvents such as chloroform. Taxol was found to partition into the bilayer, perturbing the hydrocarbon chain conformation. The taxol C13 side chain was found to be fluorescent, and it displays an environment-sensitive shift in emission spectrum; taxol fluorescence was used to confirm the insertion of the drug into the bilayer. Taxol induces a broadening of the DPPC phase transition, and the location of the drug in the bilayer depends on drug concentration. Incorporation of taxol affects other physical properties of the bilayer such as the lipid order parameter, and this fluidizing effect was also observed upon incorporation of taxol in biological membranes isolated from basolateral plasma membranes of rat liver. These studies demonstrate that taxol incorporated into liposomes penetrates into the acyl chain domain of the bilayer and alters the physical properties of both artificial and biological membranes.
