Sentence |
denotes |
Moreover, the rapid emergence of SARS-CoV-2 has exposed one of the main weaknesses in the current medical landscape: the lack of broad-spectrum antiviral drugs. |
| T62 |

Sentence |
denotes |
At present, there are only a handful of approved antivirals, and they are mostly virus-specific. |
| T63 |

| T64 |
353-536 |
Sentence |
denotes |
Some research efforts have been focused on the development of broad-spectrum drugs, which could potentially offer some efficacy against future emerging viruses (and maybe SARS-CoV-2). |

711-993 |
Sentence |
denotes |
In most known respiratory viruses,42 the VAL targets either heparan sulfate proteoglycans (HSPG)43 or sialic acids (SA).44 Both HSPG and SA mimics have shown in vitro ability to bind to viruses, blocking their interaction with cell membranes, and often in a broad-spectrum way.45−47 |
