Interestingly no antibacterial activity against E. coli suggesting that this hydroxylation leads to loss of the antimicrobial activity . Furthermore, asperflavin ribofuranoside (162) which was isolated earlier from the marine fungus Eu. cristatum EN 220 and the marine-derived fungus Microsporum sp. , was reported as a potent free radical scavenging agent with an IC50 value of 14.2 μM with better antioxidant activity than the standard antioxidant, ascorbic acid which had an IC50 value of 20.0 μM . Also, it exhibited modest antibacterial activity against both , whereas fusaranthraquinone (165) did not demonstrate any antibacterial activity when it was tested against both S. aureus and MRSA . Interestingly, additional bioactive fusaquinons A-C (166-168) were reported from the marine fungus Fusarium sp. ZH-210 and displayed weak cytotoxic activity against MCF-7, KB, and KBv200 cell lines with IC50 values of more than 50 μM .
