Mitochondria are vital for energy production and rely on intricate nucleic acid structures to regulate gene expression. Using DNP‐ssNMR (dynamic nuclear polarization solid‐state NMR), we observed G‐quadruplex formation in intact mitochondria treated with berberine.

Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.

Fungal alkaloid occurrence during seedling establishment and early growth in Lolium perenne seedlings infected with Epichloë festucae var. lolii and the influence of adult Argentine stem weevil (Listronotus bonariensis) feeding on alkaloid concentrations : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science (MSc) in Agriculture Science at Massey University, Palmerston North, New Zealand [PDF]
Fungal endophytes of the genus Epichloë often form stable, symbiotic, and mutualistic relationships with grasses of the Pooideae, including perennial ryegrass (Lolium perenne L.).

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

Herein we present a novel one‐por methodology for the synthesis of enantioenriched 2H‐pyrrolespirosuccinimides by copper‐catalyzed reactions on Ugi adducts derived from enantiopure α‐alkylbenzyl amines through a chirality transfer process. We have proposed a mechanism supported by density functional theory (DFT) calculations, where a hydrogen radical ...

This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...
