摘要:
Biocompatible non-toxic triblock copolymers having an A-B-A structure wherein each A is a hydrophilic, biocompatible end block and the B middle block is a hydrophobic desaminotyrosyl tyrosine polycarbonate or polyarylate. The copolymers spontaneously self-assemble to form low critical aggregation concentration nanospheres having utility as delivery vehicles for hydrophobic biologically or pharmaceutically active compounds.
摘要:
New bioresorbable polymers are synthesized from monomer analogs of natural metabolites In particular, polymers are polymerized from analogs of amino acids that contribute advantageous synthesis, processing and material properties to the polymers prepared therefrom, including particularly advantageous degradation profiles.
摘要:
Biocompatible, bioresorbable polymers comprising a plurality of monomeric repeating units containing an amide group, wherein said amide groups are N-substituted and the N-substituent and degree of N-substitution are effective to lower the melt viscosity, the solution viscosity, or both, compared to the same polymer without N-substitution.
摘要:
This invention discloses biocompatible polymers prepared from monomers (IV), and (IVa), or derivatives thereof, for which the variables are described in the claims and specification. These polymers may be bioresorbable and thus useful for manufacture of medical devices. Therefore, methods for preparing these polymers and medical devices prepared therefrom are also encompassed by this disclosure.
摘要:
The present invention relates to new classes of biocompatible polymers comprising at least one repeating unit derived from a compound of Formula (I) as defined in the claims and specification. These polymers may be biodegradable and bioresorble, and, while not limited thereto, may be adapted for radio-opacity and are useful for medical device applications and controlled release therapeutic formulations. Therefore, methods for preparing these polymers and medical devices prepared therefrom are also encompassed by this disclosure.
