Abstract: Abstract A first total synthesis of alstofonidine is described from the pentacyclic core, an advanced intermediate reported previously. The pentacyclic core facilitated putative biosynthetic congener access, thereby allowing a rapid synthesis of alstofonidine from the… read more here.

Abstract: Two new elaiophylin derivatives, efomycins K (1) and L (2), and five known elaiophylin derivatives (3–7) were isolated from the termite-associated Streptomyces sp. M56. The structures were determined by 1D and 2D NMR and HR-ESIMS… read more here.

DOI: 10.3390/life11080758
Abstract: Tolyporphins A–R are unusual tetrapyrrole macrocycles produced by the non-axenic filamentous cyanobacterium HT-58-2. A putative biosynthetic gene cluster for biosynthesis of tolyporphins (here termed BGC-1) was previously identified in the genome of HT-58-2. Here, homology… read more here.
