标 题:Structural modification of resveratrol: sodium resverastatin phosphate
发明人：PETTIT GEORGE R; GREALISH MATTHEW P
权利人:UNIV ARIZONA
摘要:Described herein are novel compounds having antineoplastic and antimicrobial activity, obtained via structural modifications of resveratrol and combretastatin A-4, methods for synthesis of these compounds, and their use in pharmaceutical composition and for use in the treatment of mammals having cancer. Examples of the novel compounds are: (Z)- and (E)-3,4′,5-trimethoxystilbene (4a, 4b); (Z)- and (E)-3,5-dimethoxy-4′-hydroxystilbene (14c, 14d); (Z)- and (E)-3-hydroxy-4′,5-dimethoxystilbene (14g, 14h); (Z)- and (E)-3,5-dihydroxy-4′-methoxy-stilbene (14k, 14l); sodium resverastatin dibenzyl phosphate ((Z)-3,5-dimethoxy-4-[O-bis(benzyl)phosphoryl]-stilbene) (14m); and sodium resverastatin phosphate (14n).

标 题 :Nucleophilic fluoroalkylation of aldehydes
发明人：STAHLY G PATRICK
权利人:ETHYL CORP
摘要:Aryl difluoromethyl sulfone adds to aldehydes under phase transfer conditions to give novel substituted alcohols of the general formula n n RCH(OH)CF.sub.2 SO.sub.2 Ar (I) n n wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.

发明人：CHRISTIAN ALLEN T; COLEMAN MATTHEW A; TUCKER JAMES D
权利人:UNIV CALIFORNIA
摘要:Amplification of chromosomal DNA in situ to increase the amount of DNA associated with a chromosome or chromosome region is described. The amplification of chromosomal DNA in situ provides for the synthesis of Fluorescence in situ Hybridization (FISH) painting probes from single dissected chromosome fragments, the production of cDNA libraries from low copy mRNAs and improved in Comparative Genomic Hybridization (CGH) procedures.
