Physically Discrete β-Lactamase-Type Thioesterase Catalyzes Product Release in Atrochrysone Synthesis by Iterative Type I Polyketide Synthase
ATEG_08451 in Aspergillus terreus, here named atrochrysone carboxylic acid synthase (ACAS), is a nonreducing, iterative type I polyketide synthase that contains no thioesterase domain. In vitro, reactions of ACAS with malonyl-CoA yielded a polyketide inte

An efficient regioselective synthesis of endocrocin and structural related natural anthraquinones starting from emodin
Endocrocin and related naturally occurring anthraquinone pigments like cinnalutein could be synthesized regioselectively via a Marschalk type reaction, starting from the natural hydroxy anthraquinone emodin. Furthermore, the new tri-O-methyl protected emodin-2-carbaldehyde may serve as a promising synthon for new bathochromically shifted, higher generation photodynamically active hypericin derivatives.

Studies on Nepalese crude drugs. XXV. Phenolic constituents of the leaves of Didymocarpus leucocalyx C. B. Clarke (Gesneriaceae)
Seven new phenolic compounds (814) including three ones having unique structure named didymocalyxins A (12), B (13) and C (14) have been isolated from the leaves of Didymocarpus leucocalyx, along with five known flavonoids (5-hydroxy-6,7-dimethoxyflavanon
