The chemistry and biology of syringolins, glidobactins and cepafungins (syrbactins)

Syrbactin is a subordinate term for the syringolin, glidobactin and cepafungin natural product families. Their grouping is based on their related molecular frameworks, similar biosynthesis pathways and, most importantly, identical modes-of-action, being irreversible proteasome inhibition. With this report, we aim to review their chemical biology, describing their common, but also differential characteristics.
