The KMM 4639 strain was identified as sp. based on two molecular genetic markers: ITS and β-tubulin regions. Chemical investigation of co-culture marine-derived fungi sp. KMM 4639 and KMM 4638 led to the identification of five new quinazolinone alkaloids felicarnezolines A-E (-), a new highly oxygenated chromene derivative oxirapentyn M () and five previously reported related compounds. Their structures were established using spectroscopic methods and by comparison with related known compounds. The isolated compounds showed low cytotoxicity against human prostate and breast cancer cells but felicarnezoline B () protected rat cardiomyocytes H9c2 and human neuroblastoma SH-SY5Y cells against CoCl-induced damage.

An KMM 4631 strain was previously isolated from a Pacific soft coral sp. sample and was found to be a source of a number of bioactive secondary metabolites. The aims of this work are the confirmation of this strain' identification based on ITS, , , and regions/gene sequences and the investigation of secondary metabolite profiles of KMM 4631 culture and its co-cultures with KMM 4689, sp.

Chemical investigation of a coculture of the marine-derived fungi KMM 4639 and KMM 4638 led to the identification of three new drimane-type sesquiterpenes, asperflavinoids B, D and E (, , ), and nine previously reported related compounds. The structures of these compounds were established using spectroscopic methods and by comparison with known analogues. We also investigated the cytotoxic activity of the isolated compounds against several cancer and normal cell lines.

Five new prenylated indole alkaloids, 17-hydroxynotoamide D (1), 17-O-ethylnotoamide M (2), 10-O-acetylsclerotiamide (3), 10-O-ethylsclerotiamide (4), and 10-O-ethylnotoamide R (5) were isolated from a co-culture of marine-derived fungi Aspergillus sulphureus KMM 4640 and Isaria felina KMM 4639. The structures of 1-5 were determined by detailed analysis of spectroscopic data and by comparison with related known compounds. The absolute configurations of 1-5 were determined by time-dependent density functional theory (TD-DFT) calculations of ECD spectra.
