19,20-Epoxycytochalasin D is a fungal metabolite that has been found in the endophytic fungus Nemania sp. UM10M. It is active against the chloroquine-sensitive and -resistant strains of P. falciparum (MIC = 0.4 ng/ml for both) without inducing cytotoxicity in Vero cells. It is cytotoxic to BT-549, LLC-PK11, and P388 cells (IC50s = 7.84, 8.4, and 0.16 µM, respectively) but not SK-MEL, KB, or SKOV3 cells up to a concentration of 10 µM.

Cytotoxic 19,20-epoxycytochalasans from endophytic fungus Xylaria cf. curta
Fitoterapia 2019 Sep;137:104253.PMID:31271786DOI:10.1016/j.fitote.2019.104253.
Nine new 19,20-epoxycytochalasans (1-9) were isolated from the rice fermentation extracts of endophytic fungus Xylaria cf. curta, along with four known compounds 19,20-epoxycytochalasin C (10), 18-desoxy-19,20-epoxycytochalasin C (11), 19,20-Epoxycytochalasin D (12) and 5,6-dihydro-7-oxo-19,20-epoxycytochalasin C (13). Their structures and absolute configurations were determined by 1D and 2D NMR, HRESIMS, X-ray diffraction and ECD calculation. The cytotoxicity of obtained compounds (1-13) was evaluated against human cancer cell lines HL-60, A549, SMMC-7721, MCF-7, and SW480. Remarkably, compound 10 showed significant specific cytotoxicity against HL-60 cell lines with IC50 value of 1.11 μM.
Tandem MS-Based Metabolite Profiling of 19,20-Epoxycytochalasin C Reveals the Importance of a Hydroxy Group at the C7 Position for Biological Activity
ACS Omega 2021 Jan 25;6(5):3717-3726.PMID:33585752DOI:10.1021/acsomega.0c05307.
Seven cytochalasins, 19,20-epoxycytochalasin N, cytochalasin P1, deacetyl 19,20-epoxycytochalasin C, 19,20-Epoxycytochalasin D, 19,20-epoxycytochalasin C, cytochalasin D, and cytochalasin C, were isolated from a fungal (Rosellinia sanctae-cruciana) crude extract. A cytotoxicity assay (sulforhodamine B) was performed on a series of cancer cell lines: HT-29, A-549, PC-3, HCT-116, SW-620, and MCF-7. Simultaneously, the liquid chromatography-mass spectrometry (LC-MS)/MS profile of 19,20-epoxycytochalasin C-treated cell lines revealed that 19,20-epoxycytochalasin C (m/z 524.25) oxidized to a metabolite of m/z 522.25 Da (-2 Da (-2H) from 19,20-epoxycytochalasin C). Further chemical oxidation of 19,20-epoxycytochalasin C using the Dess-Martin reagent produced an identical metabolite. It has been noticed that the parent molecule (19,20-epoxycytochalasin C) showed an IC50 of 650 nM (on HT-29), whereas for the oxidized metabolite (m/z 522.24) of 19,20-epoxycytochalasin C, the IC50 was >10 μM. It is clear that the parent molecule had 16 times higher cytotoxic potential as compared to the oxidized metabolite. The spectroscopic investigation indicated that the oxidation of the hydroxyl (-OH) group occurred at the C7 position in 19,20-epoxycyctochalsin C and led to the inactivation of 19,20-epoxycytochalasin C. Further, cell cycle analysis and histopathological evidence support the findings, and CDK2 could be a possible target of 19,20-epoxycyctochalasin C.
