Botulinumneurotoxins serotype A (BoNT/A) is the deadliest toxins known to humans and the "Category A" agent for bioterrorism. Over the past 20 years, significant efforts have been put forth to develop effectiveinhibitors of BoNT/A. Unfortunately, few identified inhibitors possess noteworthy efficacy against BoNT/A in vivo. Here, we performed a high-throughput virtual screening based on the structure-based
A series of novel α-ketoamide derivatives bearing a vanillin skeleton were designed and synthesized. Bioactivity tests on virus and bacteria were performed. The results indicated that some compounds exhibited excellent antitobacco mosaic virus (TMV) activities, such as compound 34 exhibited an inactivation activity of 90.1% and curative activity of 51.8% and compound 28 exhibited a curative activity

A practical two pot synthesis of N-arylpiperazinones from the corresponding aniline is described. The key transformation is a selective intramolecular Mitsunobu cyclodehydration of an amidoalcohol intermediate. A series of N-arylpiperazinones were prepared in yields up to 89%.

continues to spread worldwide, with 25 million confirmed cases and 800 thousand deaths. Effective treatments to target SARS-CoV-2 are urgently needed. In the present study, we have identified a class of cyclic sulfonamide derivatives as novel SARS-CoV-2 inhibitors. Compound 13c of the synthesized compounds exhibited robust inhibitory activity (IC50 = 0.88 μM) against SARS-CoV-2 without cytotoxicity
