Differential metabolism of benzo[a]pyrene and benzo[a]pyrene-7,8-dihydrodiol by human CYP1A1 variants [PDF]
Carcinogenesis, 2001 Cytochrome P450 1A1 (CYP1A1) plays a key role in the metabolism of carcinogens, such as benzo[a]pyrene (B[a]P) and metabolites to ultimate carcinogens. Three human allelic variants, namely wild-type (CYP1A1.1), CYP1A1.2 (I462V) and CYP1A1.4 (T461N), were coexpressed by coinfection of baculovirus-infected insect cells with human NADPH-P450 reductase ...

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons
Chemistry – A European Journal, EarlyView.Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...
