Neohydroxyaspergillic acid is a fungal metabolite produced by A. sclerotiorum that has antibiotic and antifungal activities. It inhibits the growth of P. aeruginosa, M. smegmatis, S. aureus, E. coli, K. pneumoniae, B. mycoides, and B. subtilis bacteria (MICs = 125-500 μg/ml). Neohydroxyaspergillic acid also inhibits the growth of G. convolute, S. consortiale, P. blakesleeanus, C. globosum, and T. mentagrophytes (MICs = 175-700 μg/ml) but not A. niger, P. notatum, M. verrucaria, or S. cerevisiae fungi.

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.

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].

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.

Epicoccone B, originally identified in C. globosum, demonstrates both DPPH free radical scavenging capability, with an IC50 of 10.8 μM, and significant α-glucosidase inhibitory activity, with an IC50 of 27.3 μM. It also possesses anti-HIV activity [1] [2].
