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.

标题:Methods and compositions of amplifying RNA
发明人：GINSBERG STEPHEN D; CHE SHAOLI
权利人:BAYLOR COLLEGE MEDICINE
摘要:The present invention pertains to a method that will increase the efficiency of second strand cDNA synthesis through a mechanism of “terminal continuationâ€? before further RNA amplification by RNA transcription using, for example, a bacteriophage promoter. In a specific embodiment, a transcription promoter is attached to the 5′ region of cDNA through the same mechanism of “terminal continuationâ€?. Genetic signals are subsequently amplified in a linear manner through RNA transcription. In specific embodiments, the orientation of the transcribed RNA is either sense or antisense, depending on the desired downstream application. In other embodiments, the present invention pertains to methods for extraction and amplification of RNA, particularly mRNA, from histologically stained tissues and cells.
