Nidulin

Nidulin is a depsidone originally isolated from A. nidulans. It is active against the bacteria M. tuberculosis and M. ranoe, as well as the fungi T. tonsurans and M. audouini. It also inhibits the growth of methicillin-resistant S. aureus (MRSA; MIC = 4 μg ml) and has larvicidal activity toward Artemia (LC50 = 2.8 μg ml). Nidulin is cytotoxic to MOLT-3 cells (IC50 = 21.2 μM) but not HuCCA-1, HepG2, or A549 cells (IC50s = >112.7 μM). It inhibits aromatase with an IC50 value of 11.2 μM.

Nornidulin is a depsidone originally isolated from A. nidulans that has antibacterial activity against M. tuberculosis and M. ranoe as well as antifungal activity against T. tonsurans and M. audouini. It also inhibits the growth of methicillin-resistant S. aureus (MRSA; MIC = 2 μg ml) and has larvicidal activity toward Artemia (LC50 = 1.7 μg ml). Nornidulin has cytotoxic activity in MOLT-3 cells (IC50 = 35.7 μM) but not HuCCA-1, HepG2, or A549 cells (IC50s = >116.4 μM).
