Pigments of fungi xxii. synthesis of racemic austrocortirubin and related tetrahydroanthraquinones

, : Pigments of fungi xxii. synthesis of racemic austrocortirubin and related tetrahydroanthraquinones. Australian Journal of Chemistry 44(10): 1447-1458

The fungal tetrahydroanthraquinones austrocortirubin (1) and austrocortilutein (3) and their deoxy derivatives (2) and (4), respectively, are synthesized in racemic form from naphthopurpurin (6).

The metabolism of 7-methoxy-2-nitro-naphtho[2,1-b]furan and the subsequent binding to DNA, under aerobic conditions, were investigated using liver microsomes of both untreated rats and rats pre-treated with 3-methylcholanthrene [3-MC]. The metabol...
