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 ...

Characterization and Phylogenetic Analysis of the Chloroplast Genome of <i>Carissa spinarum</i> L. (Rauvolfioideae, Apocynaceae). [PDF]

Ecol Evol
In this study, we present the first de novo assembled chloroplast genome of Carissa spinarum L. and provide detailed insights into its genomic features. This is the second genome we are characterizing from the genus Carissa L. as before the article on Carissa macrocarpa exists. Furthermore, we reconstructed the phylogenetic relationships of C. spinarum
