“…Later, a broad spectrum of biological activities have been added like antioxidant, increase of cellular glutathione level, suppression of poly ADP (adenosine diphosphate)-ribose polymerase (PARP) activation 11 , as well as these compounds potentiate the expression of some redox-sensitive genes associated to mitogen-activated protein kinase (MAPK), AP-1 and Nrf2 factors 12,13 . TYK inhibitors, except being broadly used in cancer clinical trials 14 , have also been evaluated in animal models of type 1 diabetes 15,16 , multiple sclerosis 17 , intestinal inflammation 18 and septic shock 19 . A number of studies have shown that in general tyrphostins express their anti-inflammatory activity by modulation of pro-inflammatory gene expression, such as cyclooxygenase-2 (COX2), inducible nitric oxide synthase (iNOS) and several pivotal cytokines ( Figure 1).…”
