摘要:
A peptide which can adopt a 310-helical conformation in which the side chains of two amino acid residues in the peptide backbone are linked by a group comprising an aromatic 5-membered ring.

摘要:
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said agent being capable of forming at least two types of binding pairs with a target.
摘要:
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, having reporters comprising gas-filled microbubbles stabilised by monolayers of film-forming surfactants, the reporter being coupled or linked to at least one vector.

摘要:
Microbubble dispersions stabilised by phospholipids predominantly comprising molecules which individually have an overall net charge exhibit advantageous stability, rendering them useful as efficacious contrast agents. An improved process for preparing microbubble-containing contrast agents is also disclosed, this comprising lyophilising an aqueous dispersion of gas microbubbles stabilised by one or more membrane-forming lipids to yield a dried product which may be reconstituted in an injectable carrier liquid to generate a microbubble-containing contrast agent.
摘要:
Ultrasound contrast agents comprising microbubbles of biocompatible gas, e.g. a sulphur halide or a perfluorocarbon, stabilized by opsonisable amphiphilic material, e.g. a membrane-forming lipid such as a phospholipid, especially a negatively charged phospholipid such as a phosphatidylserine, may exhibit prolonged contrast-generating residence time in the liver following intravenous administration.
摘要:
Microparticulate contrast agents comprising gas or a gas precursor encapsulated by a non-polymeric and non-polymerisable wall-forming material are readily characterisable materials exhibiting surprising structural integrity and stability.
