Thanks for your posting. I am curious how many of the links you posted were chloroquinine (or HC) in vitro only, versus in vivo on mice - - versus in vivo on human subjects ?

Yes, you start with molecular studies, then in-vitro, then in-vivo, then in humans, and in the end, sometimes it gives good results, sometimes not.
