This invention relates to compounds for the inhibition of histone deacetylase. More particularly, the invention provides for compounds of the Formula (I) and N-oxides, hydrates, solvates, pharmaceutically acceptable salts, prodrugs and complexes thereof, and racemic and scalemic mixtures, diastereomers and enantiomers thereof, wherein groups L, M, X and Y are as defined herein.
摘要:
This invention relates to compounds that inhibit protein tyrosine kinase activity. In particular the invention relates to compounds that inhibit the protein tyrosine kinase activity of growth factor receptors, resulting in the inhibition of receptor signaling, for example, the inhibition of VEGF receptor signaling and HGF receptor signaling. More particularly, the invention relates to compounds, compositions and methods for the inhibition of VEGF receptor signaling and HGF receptor signaling. The invention also provides compositions and methods for treating cell proliferative diseases and conditions.

摘要:
There is disclosed a process for producing carbapenam diazo intermediates of the formula ##STR1## wherein R.sup.1 is hydrogen or a hydroxy-protecting group,R.sup.2 is a lower alkyl having from 1-6 carbon atoms, andR.sup.3 represents a conventional carboxyl-protecting group.The processs comprises alkylating a 4-substituted azetidinone with the tin enolate of an .alpha.-bromoketone, in the presence of a silver salt, iodine, or iodine salt as a catalyst, and a strongly polar solvent. The .beta./.alpha. yield of the product diazo intermediate is approximately 3/1.

摘要:
A process is disclosed for the deprotection of allylic esters and ethers. The process comprises reacting an allyl ester of a carboxylic acid or an allyl ether of a phenol with pyrrolidine or piperidine and a catalytic amount of an organic-soluble palladium complex having a coordinating phosphine ligand to cleave the allyl moiety. The resultant carboxylic acid or phenol is then recovered.
