Multiple convergence in polyketide biosynthesis: a third folding mode to the anthraquinone chrysophanol

Chemical Communications, 2009
The polyketide chrysophanol is shown to be formed, in an organism-specific way, by a third folding mode, involving a remarkable cyclization of a bicyclic diketo precursor, thus establishing the first example of multiple convergence in polyketide biosynthesis.

Experimental and theoretical studies of pyrolysis of chrysophanol and its derivatives

Journal of Analytical and Applied Pyrolysis, 2013
Abstract Rhubarb has been used as a tobacco additive recently. In order to understand the smoke emissions of herbal cigarettes with rhubarb additive, the pyrolysis of major components of rhubarb: chrysophanol and its derivatives (emodin, rhein and aloe-emodin) have been studied by synchrotron VUV photoionization mass spectrometry (SVUV-PIMS) combined

Promotion of Ferroptosis in Oral Cancer Cell Lines by Chrysophanol

Current Topics in Nutraceutical Research, 2019
Oral cancer is a type of head and neck cancer that can be life threatening if not diagnosed and treated early. Ferroptosis is a type of programmed or regulated cell death dependent on iron and reactive oxygen species but is a caspase-independent form of non-apoptotic cell death. Therefore, there is a need to identify candidate natural compound that may
