1 Oxidative deboronation of the peptide boronic acid proteasome inhibitor bortezomib: contributions from reactive oxygen species in this novel cytochrome P450 reaction. Reactive Oxygen Species cytochrome P450 family 2 subfamily B member 6 Homo sapiens
2 Chemically generated reactive oxygen species (ROS), such as those generated as byproducts during P450 catalysis, were also found to deboronate 1 resulting in the formation of M1 and M2. Reactive Oxygen Species cytochrome P450 family 2 subfamily B member 6 Homo sapiens
3 Chemically generated reactive oxygen species (ROS), such as those generated as byproducts during P450 catalysis, were also found to deboronate 1 resulting in the formation of M1 and M2. Reactive Oxygen Species cytochrome P450 family 2 subfamily B member 6 Homo sapiens
4 The presence of superoxide dismutase (SOD) and catalase prevented the deboronation of 1, thus, supporting the involvement of ROS in the P450 2E1-catalyzed deboronation reaction. Reactive Oxygen Species cytochrome P450 family 2 subfamily B member 6 Homo sapiens
5 Our present findings indicate that the oxidase activity of P450 (i.e., formation of ROS) represents a mechanism of deboronation. Reactive Oxygen Species cytochrome P450 family 2 subfamily B member 6 Homo sapiens
