摘要:
The present invention provides fusion polypeptides comprising polypeptide ligands that are modified by circular permutation and fused to at least one polypeptide fusion partner wherein such fusion polypeptides have new, improved or enhanced biological functions or activities. Such improvements include, but are not limited to, increased binding affinity, increased activity, increased agonist activity (super agonist), antagonist activity, increased accessibility, increased flexibility of the active site, increased stability, broader and/or changed substrate specificity, and combinations thereof.

摘要:
The present invention relates to a novel functional peripherally-acting μ opioid receptor antagonist of Formula I: The novel compounds of the present invention have reduced oral bioavailability without compromising opiate-induced analgesia in the CNS. The compounds of the present invention are further efficacious at low doses and are useful in treating gastrointestinal conditions associated with opioid analgesic therapy.
摘要:
The invention relates to the discovery that pamoate salt of aripiprazole results in a good to superior long acting and/or extended release profile. Thus, in one aspect of the invention, the invention includes pamoate salt of aripiprazole. Preferably, the pamoate salt is characterized by a ratio of aripiprazole to pamoate of 1:1 or 2:1. The invention further relates to methods of treating an individual in need thereof comprising administering a pharmaceutical composition comprising a pamoate salt of aripiprazole.
摘要:
This invention relates to compositions for the sustained release of biologically active polypeptides, and methods of forming and using said compositions, for the sustained release of biologically active polypeptides. The sustained release compositions of this invention comprise a biocompatible polymer having dispersed therein, a biologically active polypeptide and a sugar.
摘要:
The present invention relates, in part, to the discovery that a pharmaceutical composition comprising aripiprazole and a carrier administered in a bolus injection resulted in an extended release profile similar to that obtained by the injection of a polylactide-co-glycolide microsphere formulation containing the active agent. This surprising result provides pharmacologically beneficial extended release formulations without the complexities and expense associated with the manufacture of microspheres.
