The present invention relates to a water-insoluble controlled-release tyrosine kinase inhibitor ("TKI") compound for use in the treatment of a cell-proliferation disorder, wherein said water-insoluble controlled-release TKI compound releases one or more TKI drug, wherein the water-insoluble controlled-release TKI compound is administered by intra-tissue administration and wherein the total amount of TKI moieties and TKI drug molecules remaining locally in such tissue 3 days after said intra-tissue administration is at least 25% of the amount of TKI moieties or TKI drug molecules administered by said intra-tissue administration; and to related aspects.
Development of a synthetic equivalent of α,α-dicationic acetic acid leading to unnatural amino acid derivatives <i>via</i> tetrafunctionalized methanes
α-disubstituted malonates. Subsequent hydrolysis followed by decarboxylation resulted in (α-indolyl-α-acylamino)acetic acid formation; homologs of tryptophan. Through this process, DEMO serves as a syntheticequivalent of α,α-dicationic acetic acid to facilitate nucleophilic introduction of the two substituents.

The application is directed to compounds of Formula (I-A) and pharmaceutically acceptable salts and solvates thereof, wherein Formula (II), R1a, R2a, R3a, R4 and Za are defined as set forth in the specification. The invention is also directed to use of compounds of Formula I-A to treat disorders responsive to the modulation of one or more opioid receptors, or as synthetic intermediates. Certain compounds of the present invention are especially useful for treating pain.
dehydration of primary amides to nitriles efficiently proceeds undermild, aqueous conditions via the use of dichloroacetonitrile as a water acceptor. A key to the design of this transfer dehydration catalysis is the identification of an efficientwater acceptor, dichloroacetonitrile, that preferentially reacts with amides over other polar functional groups with the aid of the Pd catalyst and makes the desired

of the homolytic bonddissociationenergies (BDEs) only, the (alpha)C-H bonds of peptides and proteins would present suitable targets for hydrogen abstraction by thiyl radicals. However, additional parameters such as polar and conformational effects may control such hydrogen-transfer processes. To evaluate the potential of thiyl radicals for hydrogen abstractionfrom (alpha)C-H bonds, we provide the
