Chemically or photochemically generated 1O2 (1Δg O2) transforms the anion of dithranol (1) into chrysazine (2), probably via an endo‐peroxide. Under basic conditions, 3O2 converts 1 to the bisanthrone 3 and to dithranol brown. The anion of dithranol is a photosensitizer. 1O2 was trapped by 2,3‐dimethyl‐2‐butene and by methyl oleate which was converted to the C‐9‐ and C‐10‐hydroperoxides. From this
化学或光化学产生的 1O2 (1Δg O2) 可能通过内过氧化物将地蒽酚 (1) 的阴离子转化为 chrysazine (2)。在碱性条件下,3O2 将 1 转化为双蒽酮 3 和地蒽酚棕。地蒽酚的阴离子是一种光敏剂。1O2 被 2,3-二甲基-2-丁烯和油酸甲酯捕获,后者转化为 C-9- 和 C-10-氢过氧化物。从这个角度来看,抗银屑病地蒽酚对花生四烯酸代谢的干扰似乎是合理的。
