Interaction of dicarboxylic metalloporphyrins with liposomes. The effect of pH on membrane binding revisited
The acid-base properties of Zn-hematoporphyrin IX (ZnHP) and Zn-mesoporphyrin IX (ZnMP) and the effect of pH on their binding to liposomes have been studied. The ionization constants for the two carboxylate groups of ZnHP were calculated by principal comp

Preparation of ω-hydroxy acids by reduction of α,ω-methylene diesters with NaBH4
By reaction of the dicesium salts of long chain dicarboxylic acids (C atoms > 9) with methylene iodide the corresponding methylene diesters were prepared. These acylals, by reduction with NaBH4 in THF, give the corresponding ω-hydroxy acids.

The Chemistry of Pyrrolic Compounds. XLV. Haematoporphyrin Derivative: Haematoporphyrin Diacetate as the Main Product of the Reaction of Haematoporphyrin with a Mixture of Acetic and Sulfuric Acids
A mixture of acetic and sulfuric acids converts haematoporphyrin into a complex mixture of porphyrins of which the main product has been characterized as the diacetate (1g).Other compounds identified in the reaction mixture were the known vinylporphyrins (1b-d), (1h) and (1i) and the isomeric monoacetoxyethyl(monohydroxyethyl)porphyrins (1l) and (1m).Analysis of the reaction mixture was complicated by the presence of 1'-ethoxyethyl derivatives (1e) or (1f), (1j) and (1k) which presumably arose by solvolysis of the corresponding acetate with ethanol present in the chloroform used for the the chromatographic separation.
