专利号:US-5569447-A 优先权日:1994-04-19 标 题:Stannylated 3-quinuclidinyl benzilates and methods of preparing radiohalogenated derivatives 发明人:LEE KAN S; HE XIAO-SHU; WEINBERGER DANIEL R 权利人:US HEALTH 摘要:The present invention provides stannylated 3-quinuclidinyl benzilate compounds and a method of synthesizing *AQNB by iodinating such stannylated 3-quinuclidinyl benzilate compounds. The iodination of these stannylated 3-quinuclidinyl benzilates proceeds in as little as five minutes; thus, the stannylated 3-quinuclidinyl benzilates may be converted to *AQNB in situ for immediate use. Using this method, radiolabelling yields as high as 80% have been observed. The present invention also is directed towards a method of synthesis of the stannylated 3-quinuclidinyl benzilate compounds. The method comprises providing a 4'-halo-3-quinuclidinyl benzilate and reacting the 4'-halo-3-quinuclidinyl benzilate with a compound having the formula (SnR 3 ) 2 , wherein R is an alkyl.
专利号:US-2005080260-A1 优先权日:2003-04-22 标 题 :Preparation of prodrugs for selective drug delivery 发明人:MILLS RANDELL L; WU GUO-ZHANG 摘要:Synthesis of a chemical compound having the formula A-B-C that may serve for applications such as drug delivery where A is a chemiluminescent, moiety, B is a photochromic moiety, and C is a biologically active moiety where A-B-C may serve as a prodrug. Novel synthetic methods of the present invention to form the prodrug comprised the steps of (1) forming a benzophenone, (2) forming a diaryl ethylene, (3) attaching a phthalimide moiety to at least one of the aryl groups of the ethylene to form a phthalimide-ethylene conjugate, (4) condensing two ethylene-phthalimide conjugates to form a phthalimide-pentadiene conjugate, (5) converting the phthalimide to the phthalhydrazide by reaction with hydrazine to form a carrier compound according to the present invention, and (6) reacting the carrier compound with an nucleophilic moiety of the drug to form the corresponding prodrug. Alternatively the carrier can be prepared by using the halo-substituted diaryl ethylene to make the corresponding cationic leuco dye-like compound with known methods. The cationic compound then is protected by reacting with a nucleophile and coupled with the aminophathalimide by palladium-catalyzed amination to form the protected phthalimide-pentadiene conjugate. The latter is refluxed with hydrazine to convert its phthalimide to the phthalhydrazide and acidified to give the carrier. An additional aspect of the present invention relates to the use of these compounds as antiviral agents for the treatment of viral infections such as HIV and as anticancer agents for the treatment of cancers such as bowel, lung, and breast cancer.
