Homoisoflavanone Delays Colorectal Cancer Progression via DNA Damage‐Induced Mitochondrial Apoptosis and Parthanatos‐Like Cell Death

Advanced Science, EarlyView.
Homoisoflavanone (HIF), a bioactive compound isolated from Polygonatum kingianum, selectively suppresses colorectal cancer progression by inducing DNA damage‐mediated mitochondrial apoptosis and parthanatos‐like cell death. HIF triggers mitochondrial dysfunction, including depolarized membrane potential, elevated ROS, and ATP depletion, while impairing

Total Synthesis of (+)‐Melonine and (+)‐N4‐Oxy Melonine Enabled by an Intramolecular Alkene Diamination Reaction

Angewandte Chemie, EarlyView.
A complexity‐generating intramolecular alkene diamination constitutes the pivotal step in the enantioselective synthesis of the title natural products featuring a strained, cage‐like pentacyclic architecture. Abstract Among more than four thousand monoterpene indole alkaloids (MIAs) isolated to date, only a few feature a 2,2,3‐trisubstituted indoline ...
