Two Sulfur-Containing Isoquinoline Alkaloids From the Bryozoan Biflustra perfragilis
The bryozoan Biflustra perfragilis collected in Bass Strait has yielded two novel sulfur-containing isoquinoline alkaloids: 2-methyl-6,7-di(methylthio)isoquinoline-3,5,8 (2H)-trione (1a) and 2-methyl-6-methylthioisoquinoline-3,5,8(2H)trione (1b).

Aporphine Alkaloids from (Annonaceae)
Guatteria species (Annonaceae) are rich in isoquinoline alkaloids that contain a restricted β-phenethylamine moiety and thus have potential as monoamine oxidase (MAO) inhibitors for the treatment of Alzheimer's and Parkinson's diseases.

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

SUMMARY Apricot (Prunus armeniaca L.) is an economically significant fruit crop worldwide with remarkable germplasm diversity, and its fruit quality is primarily determined by key metabolites (e.g., sugars, organic acids, and flavonoids). However, current apricot genome assemblies remain incomplete, with substantial unanchored regions that hamper ...
