The disclosure discloses a sulfur-containing polycyclic-hydroxypyridone carboxamide analog against HIV and an application thereof. The sulfur-containing polycyclic-hydroxypyridone carboxamide analog has a compound represented by the following formula (I) or a stereoisomer thereof or a pharmaceutically acceptable salt thereof. The sulfur-containing polycyclic-hydroxypyridone carbonxamide analogs provided by the disclosure have good anti-HIV activity, and in particularly, compound 2, compound 18, compound 34 and compound 66 have strong inhibitory effects on HIV-1 replication in vitro, and the therapeutic index thereof against HIV is hundreds of times greater than that of the existing drugs TDF and Dolutegravir. The development of such the compounds is of great significance for the development of AIDS drugs and will bright good news to AIDS patients.

The present invention relates to compounds of formula (I) and their use for treating or preventing a bacterial infection or as an antibacterial agent and/or as a -lactamase inhibitor.
