  5-LOX in colorectal cancer Colorectal cancer (CRC) like other malignancies exhibits an overexpression of 5-LOX. Ohd et al. (Ohd et al., 2003) revealed in a study that malignant colon tissues overexpress 5-LOX activity and retain elevated levels of inflammatory mediators, leukotrienes. Additionall

  Introduction 5-hydroxytryptamine (5-HT) is found throughout the body and influences smooth muscle activity in various tissues including the intestine, vasculature and urinary Luciferase Reporter Assay Kit (Kim and Camilleri, 2000, Klarskov and Horby-Petersen, 1986, Mohammad-Zadeh et al., 2008).

  The benzimidazole group seems to be a key feature for the excellent anti-tumor activity of galeterone (159), which motivated the synthesis of new steroidal inhibitors containing N-heterocyclic groups structurally related to benzimidazole. Thus, several 1H- and 2H-indazole derivatives of dehydroepian

  2024-06-07

  

  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  2024-06-07

  

  The identification of novel kinase inhibitor scaffolds is highly desirable in order to develop selective kinase inhibitors. Small-molecule inhibitors of Interleukin-2-inducible T-cell kinase (Itk) that are based on the 3-aminopyridin-2-one fragment 1 have been reported. Despite derivatisation of 1 y

  To evaluate the ability of both sets of compounds to inhibit the activity of 15-LOX an initial screen was performed, whose results are shown in . The comparison of inhibition values would seem to indicate that, in the HYD series, an electron donor group at the position increases and an electron at

  Based on its kinetic parameters and quaternary structure, R. pycnus arginase is a typical ureotelic L-arginase [2]. The Km value of the enzyme was lower than other arginases from other organisms (Table 2), including S. cerevisiae (15.7mM), B. anthracis (10mM), B. caldovelox (3.4mM), human liver (2.3

  Although the earlier studies focused on the antioxidant capacity of tocopherols, ascorbic STA-21 and carotenoids, then it was noticed that phenolic compounds were more powerful than others (Rice-Evans, Miller, & Paganga, 1996). Phenolic compounds, the most numerous and ubiquitous groups of plant sec

  Most clinically approved antiangiogenic drugs are aimed at blocking the action of vascular endothelial growth factor, or VEGF, which is accepted to be the most important tumor-derived angiogenic factor, stimulating proliferation and migration of endothelial cells, as well as branching of vessels (Fe

  Sustained release property is also associated with side effects reduction [16] that could be confirmed by histopathological analyzes. Massive infiltrating inflammatory cells, hyperproliferation of skin layers and keratin pearls, caused by DMBA and croton oil application [32] are attenuated in Imq-lo

  Aerobic exercise plays an important role in the regulation of cytochalasin d metabolism in the skeletal muscle. It is also associated with increases in AMPK and GLUT4 levels, resulting in the improvement of the glucose uptake signaling pathway [17,18]. Recently, it has been shown that exercise marke
