    Abstract: An improved process for producing ethylenically unsaturated phosphate ester compounds, especially 2-(methacryloyloxyethyl)-2' (trimethylammoniomethyl) phosphate, (HEMA-PC) comprises a two step reaction in the first of which a phospholane reagent is reacted with a hydroxyl containing ethylenically unsaturated starting material, and in the second of which the intermediate formed in the first step is ring opened by reaction with trimethylamine to produce a zwitterionic product. In the process the two steps of the reaction are carried out in the same solvent with substantially no removal or addition of solvent after the first step. The solvent is preferably acetonitrile. The use of pure reagents avoids the production of undesirable by-products.

It has been unexpectedly found that liposomes comprising one or more of these cationic phospholipids are effective in the lipofection of nucleic acids. These novel phospholipids are particularly attractive because of they are not only effective in lipofection, but are extremely cheap and easy to make.

  • Patent number: 5659061
    Abstract: The composition, synthesis, and applications of tumor associated protease activated prodrugs of phosphoramide mustard, isophosphoramide mustard and analogs with detoxification functionalities are described. These drugs release a cytotoxic phosphoramide mustard analog following activation by tumor associated proteases and esterases. The general structure for these drugs is: ##STR1## Wherein R1 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; wherein X is a good leaving group such as a halogen; R2 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; or an amino group (NH.sub.2) which may optionally be substituted. Wherein A is a benzyloxy derivative with one or more acyloxy or acylamino groups in para or ortho portions relative to the phosphoester; and wherein the acyloxy or acylamino groups are not (substituted or unsubstituted) p-guanidino-benzoyloxy groups or p-guanidino-benzoylamino groups.

  • Patent number: 5591731
    Abstract: The present invention relates to a sterile, stable vacuum dried crystalline amifostine composition and, optionally, pharmaceutically acceptable excipient(s). Typically, the crystalline compositions of the present invention exhibit enhanced stability at temperatures ranging from about 4.degree. C. to about ambient temperature for a period of at least 2 years relative to existing solid vacuum dried amorphous amifostine preparations. The reconstituted compositions of the present invention are suitable for administration to humans as a radio- or chemoprotecting agent.

  • Patent number: 5556710
    Abstract: Compounds of formula (I), in which the groups R are hydrogen or C.sub.1-4 alkyl, n is from 2 to 4, X is alkylene, poly(ethoxy) or an aryl-containing group, Y is a valence bond or a divalent functional or heterocyclic group or a trivalent alkylene group, and Z is a sulphur-containing group which contains a thiol or disulphide group are useful to provide biocompatible treatments of metal surfaces, such as silver and gold surfaces. Processes for the preparation of the compounds, intermediates useful in such processes, articles having a metal surface treated with such compounds and processes of rendering metal surfaces biocompatible which comprise treating the metal surfaces with them.
