- MONOMERS CAPABLE OF DIMERIZING IN AN AQUEOUS SOLUTION, AND METHODS OF USING SAME
-
Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.

- Total syntheses of dalesconol A and B
-
(Chemical equation Presented) (Chemical equation Presented) A polycyclic collapse: Use of a carefully designed acyclic intermediate participated in a cascade reaction that formed the entire core of the polyketide-derived dalesconols in a single flask (see scheme). A number of additional and carefully controlled synthetic operations completed an expeditious synthesis of both of these highly bioactive natural products as well as structural congenors.

- NEODIHYDROTHEBAINE AND BRACTAZONINE, TWO DIBENZAZONINE ALKALOIDS OF PAPAVER BRACTEATUM
-
Two new dibenzazonine alkaloids, neodihydrothebaine and bractazonine were isolated from Papaver bracteatum.Their possible biosynthesis from thebaine is discussed.The structures of both new alkaloids are proven by synthesis.An isomeric dibenzazonine compound was also prepared. - Keywords: Papaver bracteatum; Papaveraceae; alkaloids; dibenzazonines; neodihydrothebaine; bractazonine; biosynthetic pathway; synthesis; 5,6,8,9-tetrahydro-2-methoxy-7-methyl-dibenzazonin-1,12-diol; 5,6,8,9-tetrahydro-2,10-dimethoxy-7-methyl-dibenzazonin-1-ol; 5,6,8,9-tetrahydro-2,11-dimethoxy-7-methyl-dibenz-azonin-1-ol; 5,6,8,9-tetrahydro-2,12-dimethoxy-7-methyl-dibenzazonin-1-ol.
