| titleOfInvention | Gas-filled amino acid block copolymer microspheres |
| abstract | (57) [Summary]nThe present invention relates to gas-filled microspheres useful as ultrasound contrast agents. More particularly, the invention relates to gas-filled microspheres prepared from amphiphilic polyamino acid block copolymers and pharmaceutically acceptable gases. The hydrophobic block of the copolymer is formed from amino acids having hydrophobic side chains (eg, leucine, isoleucine, valine, and phenylalanine), and the hydrophobic block of the copolymer is formed of amino acids having hydrophilic side chains (eg, glutamic acid (eg, glutamic acid). And its ionized form, glutamate), aspartic acid (and its ionized form, aspartate), and lysine). |
