Patent number: 9446155Abstract: The present invention provides polypeptides, peptide dimer, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a KD<1 ?M), and dimer and multimeric constructs comprising these polypeptides.Type: GrantFiled: December 17, 2013Date of Patent: September 20, 2016Assignees: Bracco Suisse SA, Dyax Corp.Inventors: Aaron K.

Publication number: 20160263254Abstract: Peptide vectors having high KDR binding affinity and processes for making such vectors are provided. The peptide vectors may be conjugated to phospholipids and included in ultrasound contrast agent compositions. Such ultrasound contrast agents are particularly useful in therapeutic and diagnostic methods, such as in imaging KDR-containing tissue and in the evaluation and treatment of angiogenic processes associated with neoplastic conditions. The present invention also provides processes for the large scale production of highly pure dimeric and monomeric peptide phospholipid conjugates as well as precursor materials used to form the conjugates. The present invention further provides processes for the large scale production of highly pure peptide phospholipid conjugates which contain very low levels of TFA.Type: ApplicationFiled: June 1, 2016Publication date: September 15, 2016Inventors: Philippe BUSSAT, Samir Cherkaoui, Hong Fan, Bernard Lamy, Palaniappa Nanjappan, Radhakrishna K.
