The FEBS Journal, Volume 293, Issue 5, Page 1341-1357, March 2026.We have converted the only known true bacterial monoterpene synthase, cineole synthase from Streptomyces clavuligerus (bCinS, C10 substrate), to a highly competent sesquiterpene synthase (C15) with a minimum number of rational mutations. By comparison with diterpene synthases (C20), we were then able to bestow diterpene synthase activity on bCinS. This

Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies
European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.
