The metabolism of xenobiotics is a critical aspect of drug discovery; nowadays, aldehyde oxidase (AOX) has emerged as a key metabolic enzyme having a pivotal role in the failures of several clinical candidates. The lack of homogenous data on possible substrates and not substrates of this enzyme represents a serious limit for the development of an in silico model for metabolism prediction. Here, we present a database of 270 chemically diverse compounds containing aza-aromatic and/or amide moieties (susceptible to human AOX), experimentally tested in vitro. The results herein reported should be useful in the development of a reliable prediction model, which should be of wide interest in chemistry, biology, biotechnology, and medicine.
A practical and sustainable photocatalyst-free protocol for photo-induced synthesis of perfluoroalkylated quinazolin-4(3H)-ones is described starting from quinazolin-4(3H)-ones. A wide range of substituted or fused-quinazolinones is found to be compatible, providing the corresponding mono- and bis-perfluoroalkylated compounds in moderate yields. This visible-light mediated C-H perfluoroalkylation allows an environmentally friendly and straightforward access to an array of unprecedented functionalized quinazolinone scaffolds, presenting attractive features for drug discovery. The control experiments demonstrated that a radical mechanism is involved in the reaction mechanism.
