Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

Integrative multi-omics reveals dark-induced coordinated interactions between alternative splicing and transport in shaping root alkaloid secretion

Industrial Crops and Products
Dark stress can alter carbon allocation patterns, which may affect root‑specific metabolites and their release into the rhizosphere of medicinal plants. However, how prolonged darkness reshapes metabolism remains poorly understood.

Antibacterial Indole Alkaloids with Complex Heterocycles from Voacanga africana.

Organic Letters, 2018
Voacafricines A and B, two unique monoterpenoid indole alkaloids each bearing five fused heterocycles, were obtained from the fruits of Voacanga africana. Their structures were elucidated by extensive spectroscopic methods and computational studies.

Detection of the Hepatotoxins, Carboxyparquin and Parquin, in Cestrum, Sessea, and Vestia Species (Solanaceae)

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Several species within the tribe, Cestreae, are implicated in being hepatotoxic to livestock. Carboxyparquin and/or parquin are implicated as the toxic principles. Herbarium vouchers are useful resources to screen for the occurrence of these toxins in species of Cestrum, Sessea, and Vestia.

Colombiains A–C, Three New Alkaloids From the Soft Coral‐Derived Fungus Cladosporium colombiae CSGL 10M10

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Three new alkaloids, colombiains A–C (1–3), together with eight known ones (4–11) were isolated from the soft coral‐derived fungus Cladosporium colombiae CSGL 10M10. Compounds 6 and 11 exhibited significant cardioprotective activity against OGD/R‐induced injury in H9c2 cardiomyocytes at 10 µM.
