Abstract:

Disclosed are multivalent, integrin-receptor antagonists that are useful in a variety of therapeutic, prophylactic, and/or diagnostic imaging modalities. In illustrative embodiments, such compounds have been prepared and utilized in the imaging, detection, localization, and/or quantitation of one or more samples of biological interest. Similarly, these compounds, as well as formulations comprising them, find utility in the prevention, treatment, and/or amelioration of one or more symptoms of a disease, abnormal condition, dysfunction, etc., including, for example proliferative diseases such as cancer in affected animals. In certain embodiments, fluorescently- or radio-labeled-non-peptidic, multivalent integrin αβcompounds are provided. Compositions including such compounds have been shown to have utility in detecting, localizing, quantitating, and/or imaging integrin αβreceptor-expressing cells, including, for example, cancer cells in vitro, in vivo, and/or in situ.

Abstract:

A bimodal polypropylene composition of at least a high molecular weight, predominantly isotactic, narrow molecular weight distribution polypropylene having a heat of fusion of 70 to 100 J/g, and a low molecular weight, predominantly isotactic, narrow molecular weight distribution polypropylene having a heat of fusion of 70 to 100 J/g, wherein the high molecular weight polymer and low molecular weight polymer are sufficiently miscible to impart a single glass transition temperature and a single melting point to the polymer blend, has improved processibility and stiffness compared to a single narrow molecular weight distribution isotactic polypropylene of the average of the components.
