"These compounds are under clinical development at phase 1/phase 2 for the treatment of acute bacterial infections, MRSA, and fungal infections." "Are" is present tense.
"was a phase 2 not done???" If they had used "were" as to acute bacterial infections and MRSA I wouldn't have disagreed with the statement. As far as fungal infections are concerned Brilacidin is not "under clinical development at phase 1/phase 2" and never has been.
As to "Who is the one lying here???" I wouldn't and didn't use the term lying. I don't know their intent but I do know they were mistaken. You're wrong all the time and I've never accused you of lying.
