Xanthoquinodin A1 is a fungal metabolite that has been found inHumicolaand has diverse biological activities.1,2It inhibitsE. tenellaschizont formation in BHK-21 cells with a minimum effective concentration (MEC) value of 0.02 μg/ml.1Xanthoquinodin A1 is active againstB. subtilis,M. luteus,S. aureus,A. laidlawii, andB. fragilisin a disc assay when used at a concentration of 1 mg/ml. It is also active againstB. cereus(MIC = 0.44 μM).2Xanthoquinodin A1 is cytotoxic to KB, MCF-7, and NCI H187 cancer cells. 1.Tabata, N., Suzumura, Y., Tomoda, H., et al.Xanthoquinodins, new anticoccidial agents produced by Humicola sp.

Chaetocin, a natural product from Chaetomium species, is a histone methyltransferase inhibitor with IC50 of 0.8 μM, 2.5 μM and 3 μM for dSU(VAR)3-9, mouse G9a and Neurospora crassa DIM5, respectively.

11-epi-Chaetomugilin I, a metabolite identified in Chaetomium globosum, demonstrates notable cytotoxic activity against several cell lines, including the murine P388 and L1210 leukemia cell lines, the human HL-60 leukemia cell line, and the human KB epidermoid carcinoma cell line [1].

Semicochliodinol, a compound that can be isolated from rice cultures of the fungus genus Chaetomium, has been identified [1].

Chaetoviridin A, an azaphilone isolated from Chaetomium globosum, is characterized as 6H-furo[2,3-h]isochromene-6,8(6aH)-dione with substitutions including a chloro group at position 5, a 3-hydroxy-2-methylbutanoyl group at position 9, a methyl group at position 6a, and a 3-methylpent-1-en-1yl group at position 3. It exhibits antifungal activity against plant pathogenic fungi.
