An NMR Analysis of 10-Indol Cytochalasin Chaetoglobosin F

Abstract

Cytochalasins are a group of natural products from fungus, and have been attracting lots of research interests in the field of microbiology. Cytochalasins possess complex and diverse structures, making nuclear magnetic resonance (NMR) based structure elucidation difficult. Chaetoglobosin F is a 10-indol cytochalasin isolated from endophytic Chaetomium globosum growing in the seeds of Panax notoginseng. This paper reported the NMR data chaetoglobosin F, along with the summarization of NMR features of 10-indol cytochalasins, providing a good reference for the further research on cytochalasins.
