The present invention refers to compounds endowed with RNA helicase DDX3 inhibitory activity of formula I and II and their therapeutic use, in particular for the treatment of viral diseases.
The reaction of N-substituted 2-aminophenols with propargylic carbonates in the presence of a palladium-catalyst is described. The functionalized dihydrobenzo[1,4]oxazines were synthesized. The palladium-catalyzed reaction of soft nucleophiles with propargylic compounds is one of the most successful palladium-catalyzed reaction developed to date. For example, a substrate having two nucleophilic moieties
Increased frequency of arbovirus outbreaks in the last 10 years represents an important emergence for global health. Climate warming, extensive urbanization of tropical regions, and human migration flows facilitate the expansion of anthropophilic mosquitos and the emerging or re-emerging of new viral infections. Only recently the human adenosinetri-phosphatase/RNA helicase X-linked DEAD-box polypeptide 3 (DDX3X) emerged as a novel therapeutic target in the fight against infectious diseases. Herein, starting from our previous studies, a new family of DDX3X inhibitors was designed, synthesized, validated on the target enzyme, and evaluated against the West Nile virus (WNV) infection. Time of addition experiments after virus infection indicated that the compounds exerted their antiviral activities after the entry process, likely at the protein translation step of WNV replication. Finally, the most interesting compounds were then analyzed for their in vitro pharmacokinetic parameters, revealing favorable absorption, distribution, metabolism, and excretion values. The good safety profile together with a good activity against WNV for which no treatments are currently available, make this new class of molecules a good starting point for further in vivo studies.

chemistry. Herein an efficient metal-free rearrangement reaction has been developed for the construction of ortho-sulfonamide phenols via HFIP-prompted intramolecularsulfonamide group 1,3-migration. This protocol features mild reaction conditions, broad functional group compatibility and good regioselectivity. Combined experimental mechanistic study and detailed DFT calculations clarified the crucial
