Talaromycesone A is a fungal metabolite originally isolated from Talaromyces.1 It is active against S. epidermidis and methicillin-resistant S. aureus (MRSA) bacteria (IC50s = 3.70 and 5.48 µM, respectively). Talaromycesone A inhibits acetylcholinesterase (AChE) in a cell-free assay (IC50 = 7.49 µM for the human enzyme).

Acetylcholinesterase inhibitors from a marine fungus Talaromyces sp. strain LF458
Mar Biotechnol (NY) 2015 Feb;17(1):110-9.PMID:25108548DOI:10.1007/s10126-014-9599-3.
Two new oxaphenalenone dimers, Talaromycesone A (1) and talaromycesone B (2), and a new isopentenyl xanthenone, talaroxanthenone (3), together with six known diphenyl ether derivatives, e.g., Δ(1',3'),-1'-dehydroxypenicillide (4), 1',2'-dehydropenicillide (5), vermixocin A (6), vermixocin B (7), 3'-methoxy-1'2'-dehydropenicillide (8), and AS-186c (9), were isolated from the culture broth and mycelia of a marine fungus Talaromyces sp. strain LF458. Compound 2 represents the first example of 1-nor oxaphenalenone dimer carbon skeleton. All isolated compounds were subjected to bioactivity assays. Compounds 1, 2, and 9 exhibited potent antibacterial activities with IC50 3.70, 17.36, and 1.34 μM, respectively, against human pathogenic Staphylococcus strains. Compounds 1, 3, and 9 displayed potent acetylcholinesterase inhibitory activities with IC50 7.49, 1.61, and 2.60 μM, respectively. Interestingly, phosphodiesterase PDE-4B2 was inhibited by compounds 3 (IC50 7.25 μM) and 9 (IC50 2.63 μM).
