Abstract
During the chemical manufacturing control processing of new paclitaxel formulations, a photodegradation impurity called C3-C11 bridge-bond isomer appeared. Our work describes the synthesis, isolation, purification, and structural characterization methods using four spectroscopies: FT-IR, UV, NMR (1H and 13 C), and LC-MS. In addition, we discovered that the C3-C11 bridge-bond isomer can promote A549 cells pyroptosis, and increase pyroptosis-related proteins, including cleaved-caspase 3, cleaved-PARP, GSDME-N, and lactate dehydrogenase, thus making it anti-tumor effects. The study offered data suggesting that the C3-C11 bridge bond isomer may be used as an anti-tumour drug in the future.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
