Clade III Synthases Add Cyclic and Linear Terpenoids to the Psilocybe Metabolome

ChemBioChem, EarlyView.
The Psilocybe cubensis terpene synthases, CubB‐CubE, were investigated. Product formation assays identified CubB as a (3R,6E)‐(‐)‐nerolidol or linalool synthase, whereas CubC is a multiproduct synthase catalyzing the formation of β‐caryophyllene and other linear and cyclic sesquiterpenes/‐terpenoids.

Structural Basis of Regioselective Bromination of Tricyclic Tryptoline by the Tryptophan Halogenase Thal

ChemBioChem, EarlyView.
This study shows that the flavin‐dependent tryptophan halogenase Thal also regioselectively halogenates the tricyclic non‐native substrate tryptoline, a β‐carboline with various pharmacological activities. Interestingly, Thal brominates a different position of the shared pharmacophore indole in tryptoline than it does in tryptophan. A crystal structure

Biosynthesis of Ephedrine Initiated by Pyridoxal Phosphate‐Dependent Formation of Cathinone

ChemBioChem, EarlyView.
An alternative pathway to ephedra alkaloids via (S)–cathinone is investigated in plants. This pathway circumvents the formation of 1‐phenylpropane‐1,2‐dione as an intermediate, which has been part of the predominantly postulated biosynthetic pathway for the last decades. This alternative pathway involves an enzymatic pyridoxal phosphate (PLP)‐dependent

Bioactivity profiles of progressively ring‐fluorinated cyclohexyl motifs in the WKYMVm peptide as formylpeptide FPR2 agonists and in keto‐piperazines as anti‐trypanosome agents.

ChemBioChem, Accepted Article.
A series of all‐cis ring fluorinated cyclohexylalanines with progressively increasing levels of vicinal fluorines, as well as 4‐fluorophenylalanine and pentafluoroarylphenylalanine were introduced into the WKYMVm peptide in place of its tyrosine residue, for assays against the G‐protein coupled formylpeptide receptor, FPR2.
