摘要:
The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side–effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.
摘要:
The present invention relates to the use of a ligand-substituted matrix comprising a support material and at least one ligand covalently bonded to the support material, the being represented by formula (I) wherein L is the linking point on the support material to which the ligand is attached; V is a spacer group; v is 0 or 1; R1 is hydrogen or C1 to C4 alkyl, preferably hydrogen or methyl; and more preferably hydrogen; R2 is hydrogen or C1 to C4 alkyl, preferably hydrogen; Ar1 is a divalent 5- or 6-membered substituted or unsubstituted aromatic ring; and Ar2 is 5- or 6-membered aromatic ring which may be unsubstituted or which is (a) attached to a further 5- or 6-membered aromatic ring via a single bond; or (b) fused to a further 5- or 6-membered aromatic or non aromatic ring, as part of a multicyclic ring system; or (c) attached to at least one substituent selected from C1 to C4 alkyl; C2 to C4 alkenyl; C2 to C4 alkynyl; a halogen; C1 to C4 haloalkyl; hydroxyl-substituted C1 to C4 alkyl; C1 to C4 alkoxy; hydroxyl-substituted C1 to C4 alkoxy; C1 to C4 alkylamino; C1 to C4 alkylthio; and combinations thereof, for affinity purification of a protein.
摘要:
Compounds having activity as phosphate transport inhibitors, more specifically, inhibitors of intestinal apical membrane Na/phosphate co-transport, are disclosed. The compounds have the following structure (I): including stereoisomers, pharmaceutically acceptable salts and prodrugs thereof, wherein X, Y and A are as defined herein.

摘要:
Provided herein are compounds having anti-proliferative effect. Also provided are compounds that can modulate the activity of multi-domain proteins comprising a dimerization arm and interdomain tether, such as EGFR, where an untethered, extended conformation is the active state and a tethered conformation is the inactive state, resulting in an autoinhibited configuration. Also provided are methods and pharmacophores for identifying such compounds. Other aspects provide methods or therapeutic treatment for proliferative diseases, disorders, or conditions, such as those associated with EGFR.
