标题 :Synthesis of combretastatin A-2 prodrugs
发明人：PETTIT GEORGE R; MOSER BRYAN R
权利人:UNIV ARIZONA STATE
摘要:The original synthesis of combretastatin A-2 (1a) was modified to provide an efficient scale-up procedure for obtaining this antineoplastic stilbene. Subsequent conversion to a useful prodrug was accomplished by phosphorylation employing in situ formation of dibenzylchlorophosphite followed by cleavage of the benzyl ester protective groups with bromotrimethylsilane to afford phosphoric acid intermediate 11. The latter was immediately treated with sodium methoxide to complete a practical route to the disodium phosphate prodrug (2a). The phosphoric acid precursor (11) of phosphate 2a was employed in a parallel series of reactions to produce a selection of metal and ammonium cation prodrug candidates. Each of the phosphate salts (2a–q) was evaluated with respect to relative solubility behavior, cancer cell growth inhibition, and antimicrobial activity.

标 题 :Molecular sieve synthesis
发明人：LESCH DAVID A
权利人:UOP INC
摘要:In the hydrothermal synthesis of crystalline microporous molecular sieves from a reaction system containing an organic templating agent, it is found that removal of at least some of the organic reagent prior to the time the formation of crystalline product is complete results in an increased yield of the product. The removal of the organic reagent disrupts the equilibrium that is normally established in the reaction system at the selected crystallization temperature between product formation and product dissolution and shifts the reaction toward the formation of additional product before a new equilibrium can form.

标题 :Synthesis of combretastatin A-4 prodrugs and trans-isomers thereof
发明人：PETTIT GEORGE R; RHODES MONTE R
权利人:UNIV ARIZONA
摘要:Combretastatin A-4 has been previously selected for pre-clinical development as antineoplastic agent. However, it is essentially insoluble in water. New water soluble derivatives of combretastatin A-4 and its qualified analogs have been discovered and synthesized through a multistage process using other derivatives of combretastatin A-4 as intermediates. These water soluble derivatives are herein denominated as “Combretastatin A-4 Prodrugsâ€?.
