On the structures of the penduflorines from Tabernaemontana penduliflora

Fitoterapia, 2023
The structures of the recently published monoterpene indole alkaloids penduflorines A and B (1a and 1b), isolated from Tabernaemontana penduliflora (Apocynaceae), have been revised. Rather than an inseparable mixture of two compounds, they appear to be the known alkaloid vobasine (2).

Stereochemical insights into sarpagan and akuammiline alkaloid biosynthesis. [PDF]

New Phytol
Summary Sarpagan and akuammiline monoterpenoid indole alkaloids (MIAs) are a class of bioactive plant‐derived compounds with significant pharmaceutical potential. These alkaloids are formed through oxidative cyclization of geissoschizine, catalyzed by homologous cytochrome P450 monooxygenases (CYP) known as sarpagan bridge enzymes (SBEs) and rhazimal ...

Insecticidal Activity of Trichilia hirta L. (Sapindales: Meliaceae) Extracts Against Spodoptera frugiperda (Lepidoptera: Noctuidae) Larvae and the Identification of Bioactive Compounds. [PDF]

Chem Biodivers
Fruits of Trichilia hirta were extracted and fractionated according to solvent polarity. The resulting partitions were screened for insecticidal activity by evaluating larval mortality and weight after 7 and 14 days. LC‐MS analysis of the most active fraction enabled the annotation of secondary metabolites potentially associated with the observed ...
