We report here on a comparative study of the activity of 10 enterovirus inhibitors against poliovirus 1, enterovirus 71 and human rhinovirus 14. Three of the selected molecules (Pleconaril, BTA-798 and V-073) are in clinical development. The in vitro antiviral activity of pairwise combinations of inhibitors indicated that most combinations resulted in an additive to slightly synergistic antiviral activity. However, the combination of ribavirin with a nucleoside polymerase inhibitor resulted in a pronounced antagonistic effect.

Extracting natural active ingredients from plants is an effective way to develop and screen modern drugs. Psoralea corylifolia is a leguminous plant whose seeds have long been used as a Traditional Chinese Medicine to treat psoriasis, rheumatism, dermatitis, and other diseases. To date, several main compounds, including coumarins, flavonoids, monoterpene phenols, and benzofurans, have been identified from the seeds of Psoralea corylifolia.

Unlabelled: Human norovirus (HuNoV) is a leading cause of gastroenteritis worldwide and is associated with significant morbidity, mortality, and economic impact. There are currently no licensed antiviral drugs for the treatment of HuNoV-associated gastroenteritis. The HuNoV protease plays a critical role in the initiation of virus replication by cleaving the polyprotein.

The main protease (Mpro) is a cysteine enzyme and represents a vital target for antiviral drug screening. In this work, Twenty-five pyrrole derivatives were synthesized and screened by enzyme activity experiments. Results indicate that six pyrrole derivatives can bind to Mpro and have inhibitory effect on Mpro.

In the last few years, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the cause of a worldwide pandemic, highlighting the need for novel antiviral agents. The main protease (M) of SARS-CoV-2 was immediately identified as a crucial enzyme for viral replication and has been validated as a drug target. Here, we present the design and synthesis of peptidomimetic M covalent inhibitors characterized by quinoline-based P moieties.
