TL;DR: Interestingly, some aporPHine, oxoaporphine, isooxoaporPhine, bisbenzylisoquinoline, and protoberberine alkaloids display more potent anticancer activities or anti-MDR effects than positive control against the tested cancer cells and are regarded as attractive targets for discovery new anticancer drugs or lead compounds.

Structural speculation and identification of alkaloids in Macleaya cordata fruits by high‐performance liquid chromatography/quadrupole‐time‐of‐flight mass spectrometry combined with a screening procedure
TL;DR: HPPLC/Q-TOF-MS combined with a screening procedure was a systematic and reliable method for speculating and elucidating the structures of alkaloids and indirectly proved that the biosynthetic pathways of benzophenanthridine alkaloid reported in Eschscholtzia california existed in M. cordata as well.

Regiospecific Minisci acylation of phenanthridine via thermolysis or photolysis
TL;DR: A new type of Minisci reaction for regiospecific acylation of phenanthridine has been developed based on cross dehydrogenative coupling (CDC) strategy, which provides an easy access to 6-acylated phen anthridine derivatives.
