We often search for autophagy inhibitors. Hydroxychloroquine is one that we often use but it has challenges related to absorption in acidic environments and currently is not available to to its use as a treatment against COVID.

Clarithromycin is another option:

Azithromycin could be another one https://cancercommun.biomedcentral.com/articles/10.1186/s40880-018-0309-9
