developed methodology rendered the use of carboxylic acids as a direct surrogate of primary amines, for the synthesis of primary ureas, secondary/tertiaryureas, O/S-carbamates, benzoyl ureas, amides, and N-formyls, exploiting the Curtius reaction. This approach has a potential to provide a diversified library of N-containing compounds, starting from a single carboxylic acid, based on the selection of the

The invention relates to pyrazolopyridines according to the general Formula I
and the salts thereof, to pharmaceutical compositions comprising the pyrazolopyridines and to a method of preparing the pyrazolopyrimidines as well as the use thereof for manufacturing a pharmaceutical composition for the treatment of diseases of dysregulated vascular growth or of diseases which are accompanied with dysregulated vascular growth, wherein the compounds effectively interfere with angiopoietin and therefore influence Tie2 signalling.
A novel series of benzoxazole analogs was designed and synthesized, and their inhibitory activities against Aurora kinases were evaluated. Some of the tested compounds exhibited a promising activity with respect to the inhibition of Aurora B kinase. A structure-activityrelationshipstudy indicated that linker length, regiochemistry, and halogen substitution play important roles in kinase inhibitory
A series of compounds containing the N‐hydroxyoxindole scaffold were synthesized and evaluated for antitumor activity. The compounds showed potent antiproliferative activity against the wild‐type p53 IGROV‐1 ovarian carcinoma cell line and considerably lower efficacy against the mutant IGROV‐1/Pt1 subline that lacks p53 function. The differential response of ovarian carcinoma cells depending on p53
