Structure-based design of protein tyrosine phosphatase-1B inhibitors
摘要:
Using structure-based design, a new class of inhibitors of protein tyrosine phosphatase-1B (PTP1B) has been identified, which incorporate the 1,2,5-thiadiazolidin-3-one-1,1-dioxide template.

The present invention relates to novel N-acylhydrazone derivatives, and more particularly to novel N-acylhydrazone derivatives having selective T cell inhibitory activity and/or anti-lymphoid malignancy activity, stereoisomers thereof, pharmaceutically acceptable salts thereof, the use thereof for preparing pharmaceutical compositions, pharmaceutical compositions containing the same, treatment methods using the compositions, and methods for preparing the novel N-acylhydrazone derivatives.
Chemodivergent reactions of 2,2-dimethoxyacetaldehyde and anilines were described, which were established on the basis of either a CC bond cleavage or a rearrangement process of a reaction intermediate. These reactions proceeded in a condition-determined manner with good functional group tolerance. In the first model, 2,2-dimethoxyacetaldehyde reacted with aniline to form a new CN bond, in the presence

e coupling reaction between N-aryl glycine esters and acylated amines has been developed. The reaction proceeded effectively under an oxygen atmosphere without the use of peroxide agents. This simple protocol allows for the preparation of a series of newcompounds in a moderate to excellent yield via the CDC reaction of a wide range of N-aryl glycinederivatives with acylated amines, which are of great

We synthesized methyl ester of N-(1-methylbut-2-en-1-yl)-N-phenylglycine which underwent acid catalyzed aromatic amino Claisen rearrangement to provide methyl-N-[2-(1-methylbut-2-en-1-yl)phenyl]glycinate. A mixture of syn- and anti-atropisomeric methyl-N-acetyl-N-[4-methyl-2-(1-methylbut-2-en-1-yl)phenyl]glycinates was obtained either by the reaction of this ester with acetyl bromide or by the reaction
