The invention relates to piperidine-based compounds of formula (I) that are used to improve UV, thermal, and thermo-oxidative stability of high performance aromatic polymers in a blend or as end-cappers of the same polymers.
Disclosed are multibinding compounds which are muscarinic receptor antagonists. The multibinding compounds of this invention containing from 2 to 10 ligands covalently attached to one or more linkers. Each ligand is, independently of each other, a muscarinic receptor antagonist or an allosteric modulator provided that at least one of said ligand is a muscarinic receptor antagonist. The multibinding compounds of this invention are useful in the treatment and prevention of diseases such as chronic obstructive pulmonary disease, chronic bronchitis, irritable bowel syndrome, urinary incontinence, and the like.
Indole compounds are disclosed. Also disclosed are methods for using the compounds to treat human and animal disease, pharmaceutical compositions of the compounds, and kits including the compounds.
Compounds useful as protease inhibitors are provided, as are methods of use and preparation of such compounds and compositions containing such compounds. In one embodiment, the compounds are useful for inhibiting HIV protease enzymes, and are therefore useful in slowing the proliferation of HIV.
