H5N1virus, one subtype of highly pathogenic influenza A virus in human infection, has recently received attention due to its unpredictable and high mortality. In this study, a series of arylsulfonamide derivatives were identified as improved H5N1inhibitors for the influenza treatment by systematic structure-activity relationship investigation. Among them, the most potent H5N1inhibitor 3h exhibited

Aza-Michael reactions between primary aliphatic and aromatic amines and various Michael acceptors have been performed under environmentally-friendly solventless conditions using acidic alumina as a heterogeneous catalyst to selectively obtain the corresponding mono-adducts in high yields. Ethylacrylate was the main acceptor used, although others such as acrylonitrile, methyl acrylate and acrylamide
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.
The possibility of the three-component condensation of hydrazoicacid and formaldehyde with primary or secondary amines, as well as with trialkylhydrazines, leading to the corresponding N-azidomethyl derivatives of amines and hydrazides was established.
