Abstract
Herein we report a practical synthetic route to the lasso peptide lassomycin () and C-terminal variant lassomycin-amide (). The biological evaluation of peptides and against Mycobacterium tuberculosis revealed that neither had any activity against this bacterium. This lack of biological activity has led us to propose that naturally occurring lassomycin may actually exhibit a standard lasso peptide threaded conformation rather than the previously reported unthreaded structure.
