Chinese Science Bulletin, 1998 Hypocrellin B (HB) is a highly effective photosensitizer. One of its derivatives, 5-brominated-hypocrellin B (5-Br-HB) has better photosensitive characterlstics than it. Using Raman spectroscopy, the microcosmic photodamage to DNA sensitized by HB and 5-Br-HB was studied at molecular level.

Synthesis of the Altertoxin I Framework
European Journal of Organic Chemistry, Volume 27, Issue 3, January 15, 2024.The core of the perylenequinone‐derived mycotoxin altertoxin I was synthesized either from 3‐hydroxyacetophenone or from 1,5‐dihydroxynaphthalene, where Suzuki couplings, Ullmann couplings, McMurry olefinations, and Friedel‐Crafts acetylation were key steps in the respective syntheses.
