Two novel cytochalasans, armochaetoglasin J and armochaetoglasin K, were isolated from Chaetomium globosum along with 14 known analogues. Their structures were elucidated using various techniques, but both armochaetoglasins J and K were found to be inactive against several cancer cell lines.
Two novel cytochalasans, armochaetoglasin J (1) and armochaetoglasin K (2), along with 14 known analogues (3-16) were isolated from Chaetomium globosum. Their structures were elucidated by HRESIMS, NMR spectroscopy, single-crystal X-ray crystallography, and ECD spectra. Armochaetoglasins J and K were found to be inactive against the HepG2, HT-29, K562, HL-60, and A549 cancer cell lines.
