dipyridopyrimidine-3-carboxamide derivatives as chitinase inhibitors. Among them, compound 6t showed the most potent activity againstbacterial chitinase SmChiB and insect chitinase OfChi-h, with a Ki value of 0.14 and 0.0056 μM, respectively. The strong stacking interaction of compound 6p with Trp99 and Trp220 found in the SmChiB–6p co-crystal structure verifies the feasibility of our design. Our results provide
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).

solvent-free conditions. Also, a double bond has been introduced into the target compounds through aryl substituted 2-cyanoacetamides under the same conditions. The advantages of this approach include no solvents, simple and practical operation (multi-component one-pot), high yields (up to 95%), and a product with potential biological activity.
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
