  • Publication number: 20110301297
    Abstract: This invention relates to ruthenium initiators for the ring-opening metathesis polymerization (ROMP) of cyclic olefins that are inactive at room temperature but activatable at elevated temperature (referred to as (“thermally switchable”). In general, these are compounds of ruthenium metal to which are bonded four or five ligands, in which one ligand is a pyridine ring in which the nitrogen is chelated to the ruthenium, or a five or six membered ring incorporating nitrogen and the ruthenium in which the nitrogen is chelated to the ruthenium.

  • Publication number: 20110189770
    Abstract: The present invention is directed to an endosome-disrupting conjugate, and methods of delivery of said conjugate to cells. The conjugates of the invention comprise a payload and an endosome-disrupting component of which the latter comprises a plurality of moieties that react under acidic conditions, e.g., within an endosome, to release gaseous endosome-disrupting molecules, e.g., CO2 and/or O2. The payload portion of the conjugate comprises molecules or particles that perform a function, e.g., diagnostic or therapeutic, within cells. The endosome-disrupting component may be selected from polymers or polymeric capsules comprising the endosome-disrupting moieties of the invention. The conjugates optionally further comprise targeting moieties.
