Abstract

The human 15-lipoxygenase-2 (h15-LOX-2) catalyzes mainly the regio- and stereospecific oxygenation of arachidonate to its corresponding hydroperoxide (15(S)-HpETE). h15-LOX-2 is implicated in the biosynthesis of inflammatory lipid mediators and plays a role in the development of atherosclerotic plaques, but it is still underexploited as a drug target. Here, to search for novel h15-LOX-2 inhibitors, we used a virtual screening (VS) approach consisting of shape-based matching, two-dimensional (2D) structural “dissimilarity”, docking, and visual inspection filters, which were applied to a “curated” ZINC database (∼8 × 10⁶ compounds). The VS was experimentally validated, and six micromolar-range inhibitors were identified among 13 tested compounds (46.2%). The K_i values could be determined for two inhibitors, compounds 10 (K_i = 16.4 ± 8.1 μM) and 13 (K_i = 15.1 ± 7.6 μM), which showed a mixed-type mechanism of inhibition. Overall, the identified inhibitors fulfill drug-like criteria and are structurally novel compared with known h15-LOX-2 inhibitors.

期刊介绍： The Journal of Medicinal Chemistry is a prestigious biweekly peer-reviewed publication that focuses on the multifaceted field of medicinal chemistry. Since its inception in 1959 as the Journal of Medicinal and Pharmaceutical Chemistry, it has evolved to become a cornerstone in the dissemination of research findings related to the design, synthesis, and development of therapeutic agents. The Journal of Medicinal Chemistry is recognized for its significant impact in the scientific community, as evidenced by its 2022 impact factor of 7.3. This metric reflects the journal's influence and the importance of its content in shaping the future of drug discovery and development. The journal serves as a vital resource for chemists, pharmacologists, and other researchers interested in the molecular mechanisms of drug action and the optimization of therapeutic compounds.
