摘要： A compound of formula (I) wherein: Q represents identical alkyl groups, cycloalkyl groups having from 5 to 7 ring atoms, or aryl or heteroaryl groups having from 5 to 12 ring atoms and R represents identical hydrogen, alkyl, alcohol or carbonyl-containing groups; or a composition containing from 5 to 100 mole % by weight of the compound of formula (I). A novel method for synthesizing the compounds of formula (I) comprises the steps of: (a) reacting a compound of the formula: Q-CHO or Q-CH(OS)(OS') wherein Q is as defined above and S and S' are independently lower alkyl, an aryl group containing from 5 to 14 ring atoms, and -(CH2)n- where n=2-4, with an excess amount of a pyrrole in the presence of a catalytic amount of a strong Lewis or Bronsted acid; (b) removing any unreacted pyrrole or other solvents used by evaporation; (c) removing polymeric materials and removing the corresponding dipyrromethane by-product, leaving the compound of formula (I).

摘要： Methods for making a pharmaceutical composition containing liposomes, which liposomes comprise a therapeutically acceptable amount of a hydro-monobenzoporphyrin photosensitizer and a mixture of phospholipids comprising egg phosphatidyl glycerol ('EPG') and dimyristoyl phosphatidyl choline ('DMPC'). The method comprises the steps of: a) combining the photosensitizer and the phospholipids in a molar ratio of about 1:7.0 or more phospholipid in the presence of an organic solvent; b) removing the organic solvent to form a lipid film; c) hydrating the lipid film with an aqueous solution at a temperature below about 300 °C, to form coarse liposomes containing a photosensitizer-phospholipid complex; and d) homogenizing or reducing the particle size of the coarse liposomes to a particle size range of about 150 to 300 nm at a temperature below about 300 °C. The invention also contemplates the liposomal pharmaceutical compositions themselves.

摘要： A method for reducing or preventing the effects of inflammation arising from injured tissue, which method comprises the steps of: a) bringing the injured tissue, or pre-injured tissue, into contact with a photosensitizing agent capable of penetrating into the tissue, resulting in the desired degree of biodistribution in less than one hour; and b) exposing the tissue thus contacted to light having a wavelength absorbed by the photosensitizing agent for a time sufficient to reduce or prevent inflammation in the exposed tissue, but not so long as to cause necrosis or erythema of the exposed tissue, or a pharmaceutical composition or an article for reducing or preventing the effects of inflammation arising from injured tissue. The composition comprises: a) from about 1 νg/mL to about 2 mg/mL of a photosensitizing agent capable of penetrating into the injured tissue, or pre-injured tissue, resulting in the desired degree of biodistribution less than one hour; and b) a pharmaceutically acceptable carrier. The article comprises: a) a photosensitizing agent capable of penetrating into the injured tissue, or pre-injured tissue, resulting in the desired degree of biodistribution in less than one hour; and b) an absorbent applicator.
