Expanding the substrate scope of a bacterial monoterpene synthase for the production of sesquiterpenoid and diterpenoid products

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

Influence of two acyclic homoterpenes (Tetranorterpenes) on the foraging behavior of anthonomus grandis Boh [PDF]

, 2016
Previous studies have shown that the boll weevil, Anthonomus grandis, is attracted to constitutive and conspecific herbivore-induced cotton volatiles, preferring the blend emitted by cotton at the reproductive over the vegetative stage.

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1064-1081, March 2026.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

Natural Carbon Isotope Composition Distinguishes Compound Groups of Biogenic Volatile Organic Compounds (BVOC) in Two Mediterranean Woody Species

Frontiers in Forests and Global Change, 2019
Our knowledge on the biosynthesis of several biogenic volatile organic compounds (BVOCs) is still limited. In this regard, natural abundant stable carbon isotope ratios (δ13C) of BVOCs may provide a powerful tool to evaluate different metabolic pathways.

Secondary metabolites of alchemilla persica growing in Iran (East Azarbaijan) [PDF]

, 2015
Phytochemical investigations of Alchemilla persica Rothm. growing in Iran were performed taking into account both the volatile and polar constituents. The hydrodistilled essential oil was analysed by GC-MS that revealed the presence of diterpenoids (19.6

Aerobic Oxidative Dethioacetalization Catalyzed by an Iron Phthalocyanine Complex

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A protocol for iron octacarboxyphthalocyanine‐catalyzed aerobic oxidative dethioacetalization in an aqueous solvent is developed. This method can efficiently convert a broad range of dithioacetals into the corresponding carbonyl compounds. Inspired by enzyme‐mediated redox processes, the environmentally friendly catalytic system exhibits remarkable ...

Structure–Activity Relationship Study of Acyclic Terpenes in Blood Glucose Levels: Potential α-Glucosidase and Sodium Glucose Cotransporter (SGLT-1) Inhibitors

Molecules, 2019
Twelve terpenoids were evaluated in the treatment of type 2 diabetes mellitus: seven monoterpenes (geranyl acetate (1), geranic acid (2), citral (3), geraniol (4), methyl geranate (5), nerol (6), and citronellic acid (7)), three sesquiterpenes (farnesal (

PERMANGANATE–PERIODATE OXIDATION: PART VII. THE OXIDATION OF SOME ACYCLIC MONOTERPENES

Canadian Journal of Chemistry, 1965
The reaction of permanganate–periodate with 1-decene and 1-octadecene in aqueous suspension or media containing tert-butanol has been studied. C10-compounds are oxidized almost quantitatively with the aqueous reagent. Myrcene, cis-ocimene, citronellol, citronellal, citronellic acid, geraniol, nerol, linalool, and linalyl acetate are all oxidized in ...
