Chemists, like artists, are able to construct new threedimensional objects, molecules and materials that exist only in the mind of a person. I became interested in creating novel molecular shapes with properties different from those found in nature shortly after arriving at Caltech in 1973. One cannot design without the brushes and paint of the craft. Indeed, modern organic chemists, standing o...

Solid-phase synthetic templates for Au nanoparticles were developed using Merrifield resins and polyamidoamine (PAMAM) dendrimers. This synthetic scheme affords the opportunity to prepare metal nanoparticles in the absence of air and water, and it does not necessitate phase transfer agents that can be difficult to remove in subsequent steps. Amine-terminated generation 5 PAMAM (G5NH2) dendrimer...
The goal of this work was to synthesize substituted polystyrene for metal extraction and/or depollution by introduction of substituted piperazines as chelatants starting from Merrifield polymer. After transformation of Merrifield’s resin in azidomethyl polystyrene, click-chemistry using copper (I)-catalyzed Huisgen’s reaction (CuAAC) was performed to prepare different polymers grafted with 1,4-...
A tridecapeptide having the amino acid sequence, less than Glu-Leu-Tyr-Glu-Asn-Pro-Arg-Arg-Pro-Tyr-Iie-Leu-OH, (The nomenclature and symbols follow the suggestions of the IUPAC-IUB Commission on Biochemical Nomenclature (1972) J. Biol. Chem. 247, 977).) has been synthesized by the Merrifield solid-phase procedure. The synthetic scheme chosen involved synthesis of the peptide in the (Gln) form a...
Synaptic ribbons are proteinaceous specialized electron-dense presynaptic structures found in nonspiking sensory cells of the vertebrate nervous system. Understanding the function of these structures is an active area of research (reviewed in Matthews G, Fuchs P. Nat Rev Neurosci 11: 812-822, 2010). Previous work had shown that ribbons could be effectively labeled and visualized using peptides ...
