SYNTHESIS OF NOVEL DERIVATIVES OF 2-CYANO-3-METHYLTHIO-3′-BENZYLAMINO ACRYLATES(ACRYLAMIDES) AND THEIR BIOLOGICAL ACTIVITY
摘要:
A series of new substituted derivatives of 2-cyano-3-methvlthio-3'-aminoacrylates(acrylamides) have been designed and synthesized. Their structures were confirmed by H-1 NMR and elemental analysis. The bioassay test indicates that most of these new compounds show good Hill reaction inhibitory activity.

The invention relates to novel dihydropyridine derivatives, of Formula (I) processes for their preparation, and their use in medicaments, especially for the treatment of chronic obstructive pulmonary diseases, acute coronary syndrome, acute myocardial infarction and heart failure development.
The present invention relates to novel arginase inhibitors of formula (I). These novel compounds are useful in the treatment of diseases that are associated with arginase activity, such as asthma, allergic rhinitis and COPD (chronic obstructive pulmonary disease).
Cyanoacetic acid derivatives are the starting materials for a plethora of multicomponent reaction (MCR) scaffolds. Here we describe valuable general protocols for the synthesis of arrays of 2-aminothiophene-3-carboxamides from cyanoacetamides, aldehydes or ketones, and sulfur via a Gewald-3CR variation. In many cases the reactions involve a very convenient work up by simple precipitation in water and filtration

A set of 5-(2-hydroxybenzoyl)-pyrid-2-ones, which are analogous to cardiotonic drugs such as milrinone, has been prepared in high yield by recyclization of 3-formylchromones with acetic acid amides having at the α-position an electron-withdrawing group. The best reaction conditions were found to be heating in DMF in the presence of Me3SiCl as a promoter and water scavenger.
