  • Patent number: 11383009
    Abstract: A new class of rapamycin 40-O-cyclic hydrocarbon esters is disclosed. The 40-O position of the rapamycin ester has the form 40-O—R, where R is C(O)—(CH2)n—X, n is 0, 1 or 2, and X is a cyclic hydrocarbon having 3-8 carbons, optionally containing one or more unsaturated bonds, and one or more linear (CH2)n) and/or cyclic (X) carbon atoms may have an OH or halide group. Also disclosed are therapeutic compositions and methods that employ the novel analogs.

  • Publication number: 20170095358
    Abstract: The invention is related to a biodegradable stent for vascular placement comprising, a tubular biodegradable metal structure, a biodegradable organic layer covering the surfaces of the structure, and optionally a biodegradable polymer coating covering the organic surface layer. The organic layer is a derivative of a monomer vapor injected plasma and is applied in a plasma enhanced chemical vapor deposition process. Thereby the biodegradable organic layer is an organosilane layer and the biodegradable polymer coating contains a therapeutic drug.
