Penicillin News and Research

RSS

Penicillin (sometimes abbreviated PCN or pen) is a group of antibiotics derived from ''Penicillium'' fungi. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections.

Scientists Mimic Fungal Process to Create Novel Medicines

Since the unintentional 1928 discovery of penicillin by Alexander Fleming, fungi have been a treasure trove of medicinal compounds for almost a century.
