Cancer-targeted therapy is an expanding and successful approach in treatment of many types of cancers. One of the main categories of targeted therapy is use of small molecule inhibitors. 15-Lipoxygenase (15-LOX) is an enzyme which reacts with polyunsaturated fatty acids and produces metabolites that are implicated in many important human diseases, such as cancer. Considering the role of 15-LOX (mainly 15-LOX-1) in the progression of some cancers, the discovery of 15-LOX inhibitors could potentially lead to development of novel cancer therapeutics and it can be claimed that 15-LOX inhibitors might be suitable as chemotherapy agents in the near future. This article reviews relevant publications on 15-LOX inhibitors with focus on their anticancer activities in vitro and in vivo. Many 15-LOX inhibitors have been reported for which separate studies have shown their anticancer activities. This review paves the way to further explore the mechanism of their antiproliferative effects via 15-LOX inhibition.

The arachidonic acid metabolic pathway is a classic inflammatory pathway. 12/15-lipoxygenase (LOX), a member of the lipoxygenase family that metabolizes arachidonic acid, has been implicated in the pathogenesis of numerous central nervous system (CNS) diseases. Ischemic stroke is a devastating disease in which the occlusion of cerebral arteries leads to a series of pathophysiological changes in brain tissue, triggering an inflammatory cascade within the brain that results in neuroinflammation.

This paper examines the quantitative structure-inhibitory activity relationship of 15-lipoxygenase (15-LOX) in sets of 100 homo- and heterocyclic compounds using GUSAR 2019 software. Statistically significant valid models were built to predict the IC50 parameter. A combination of MNA and QNA descriptors with three whole molecular descriptors (topological length, topological volume and lipophilicity) was used to develop 18 statistically significant, valid consensus QSAR models.

Inflammation is a complex physiological response associated with the onset and progression of various disorders, including diabetes. In this study, we synthesized a series of diclofenac acid derivatives and evaluated their potential anti-diabetic and anti-inflammatory activities. The compounds were specifically assessed for their ability to inhibit 15-lipoxygenase (15-LOX) and α-glucosidase enzymes.

Prostate cancer (PCa) has become a common disease among middle-aged and elderly men. The lipoxygenase (LOX) pathway plays a crucial role in the occurrence, development, invasion and metastasis of PCa and is therefore considered a new target for the prevention and treatment of PCa. 5-LOX and 12-LOX have a promoting effect on the occurrence, development, invasion and metastasis of PCa.

Compounds of natural origin found in varying quantities in plant-based products constitute a highly significant category, possessing structural significance as well as the capacity to regulate oxidative processes. The activity of these compounds may be modulated by the composition of the biological environment in which they operate, the pH of the environment, or the presence of metal cations in plants or plant extracts. A successful complexation reaction was mainly confirmed by FT-IR, observing the shift from the original transmittance of catechin bonds, especially O-H ones.
