Poly(ester amide) co-polymers promote blood and tissue compatibility.

A family of biodegradable poly(ester amide) (PEA) co-polymers based on naturally occurring alpha-amino acids has been developed for applications ranging from biomedical device coatings to delivery of therapeutic biologics. An important feature of PEA co-polymer coatings may be their ability to promote a natural healing response. To gain insight into this process, representative elastomeric PEAs designed for a cardiovascular stent coating were compared to non-degradable and biodegradable polymers in a series of in vitro assays to examine blood and cellular responses.

Integrated approaches to therapeutic target gene discovery.

The identification of tractable drug targets is the first critical step in the long process of drug development, and the challenge for scientists in the post-genomic era is to couple gene and protein sequence information with biological insight to identify genes with the greatest therapeutic and commercial potential. An extraordinary array of genomics- and proteomics-based techniques is available for this endeavor, and combining multiple, complementary approaches enhances the informative power of such experimentation.
