Our research to discover potential new multitarget agents led to the synthesis of 10 novel derivatives of cinnamic acids and propranolol, atenolol, 1-adamantanol, naphth-1-ol, and (benzylamino) ethan-1-ol. The synthesized molecules were evaluated as trypsin, lipoxygenase and lipid peroxidation inhibitors and for their cytotoxicity. Compound 2b derived from phenoxyphenyl cinnamic acid and propra...

15-Lipoxygenase-1 (15-LOX-1) oxidizes polyunsaturated fatty acids to a rich spectrum of biologically active metabolites and is implicated in physiological membrane remodelling, inflammation and apoptosis. Its deregulation is involved in the pathogenesis of diverse cancer and immune diseases. Recent experimental evidence reveals that dynamic histone methylation/demethylation mediated by histone ...

The lysyl oxidase (LOX) gene reverted Ras transformation of NIH 3T3 fibroblasts and tumor formation by gastric cancer cells, which frequently carry mutant RAS genes. The secreted lysyl oxidase proenzyme is processed to a propeptide (LOX-PP) and a functional enzyme (LOX). Unexpectedly, the tumor suppressor activity mapped to the LOX-PP domain, which inhibited tumor formation and the invasive phe...

Lipoxygenases (LOXs) are nonheme iron-containing enzymes that catalyze dioxygenation of free or esterified polyenoic fatty acids to the corresponding hydroperoxides.1 Although LOXs in plants have been known for almost a century, the first mammalian LOXs were not discovered until the mid 1970s.2 In 1984 a 15-LOX activity was described in human atherosclerotic lesions,3 and since then the number ...

background and objectives: the seed extract of silybum marianum contains seven flavonolignans known collectively as silymarin. these metabolites can be produced in hairy root cultures of s. marianum. the effect of different physical factors can change root biomass and silymarin production which has been investigated in the present study. methods: the effect of different physical factors of temp...

The expression of lipoxygenases (LOXs) is known to be developmentally regulated in soybeans (Glycine max. [L.] Merr.). Hormones have been firmly established as being involved in the growth and developmental processes of a number of plant species. Correlation between the expression of LOXs and the development and germination of soybean embryos suggests that plant hormones may affect the expressi...

In octocorals, a catalase-like allene oxide synthase (AOS) and an 8R-lipoxygenase (LOX) gene are fused together encoding for a single AOS-LOX fusion protein. Although the AOS-LOX pathway is central to the arachidonate metabolism in corals, its biological function in coral homeostasis is unclear. Using an acute incision wound model in the soft coral Capnella imbricata, we here test whether LOX p...

The cerebellum fine-tunes motor activity via its Purkinje cell output. Purkinje cells produce two different types of spikes, complex spikes and simple spikes, which often show reciprocal activity: a periodical increase in complex spikes is associated with a decrease in simple spikes, and vice versa. This reciprocal firing is thought to be essential for coordinated motor behavior, yet how it is ...

prostate cancer is a devastating disease for which current therapies are inadequate. various lines of evidences have suggested the 5-lipoxygenase (5-lox) pathway and the leukotriene receptor pathway are potential targets for prevention or treatment of prostate cancer. thus, search for new anti-cancer drugs targeting 5-lox and leukotriene is very essential and important. the objective of the pre...
