Abstract:
The invention relates to compounds of formula: wherein R1 is selected from the group consisting of fatty acid acyl groups of 12 to 30 carbon atoms and fatty alcohol groups of 12 to 30 carbon atoms, and wherein R2 is selected from the group consisting of H, fatty acid acyl of 12 to 30 carbon atoms and fatty alcohol groups of 12 to 30 carbon atoms, the same as or different from R1, and the residue of a nutrient, drug, or other bioactive compound, and to the use of these compounds to deliver drugs and other bioactive compounds.
Abstract:
A tetrakis(hydroxyphenyl)chlorin, bacteriochlorin or isobacteriochlorin, derivatised at one or more of the hydroxy groups by addition reaction with a diisocyanate, diisothiocyanate or isocyanate-isothiocyanate at one isocyanate or isothiocyanate group thereof, the other isocyanate or isothiocyanate group being itself derivatised by addition reaction with the hydroxy group of an w-alkylated or acylated poly(alkylene oxide) or to a hydroxy group of a link residue itself carrying a residue of such poly(alkylene oxide).
Abstract:
Compounds, compositions, and methods of use as a pharmaceutical, where the compounds have structure (I), where B is --C(.dbd.O)-- or --CH.sub.2 --O--, C is a direct bond or is a diol residue, a hydroxy-substituted carboxylic acid residue, or a dicarboxylic acid residue, and D is a fatty acid residue or a fatty alcohol residue, where the acid residues or alcohol residues for ester linkages with the corresponding alcohols or acids.
