While the mammalian eye is seldom considered an organ of drug metabolism, the capacity for biotransformation is present. Compared to the liver, the metabolic capabilities of the eye are minuscule; however, phase I and phase II metabolic activities have been detected in various ocular structures. The careful consideration of ocular tissue metabolic processes within the eye has important implicat...

It has long been recognized that energy metabolism is linked to the production of reactive oxygen species (ROS) and critical enzymes allied to metabolic pathways can be affected by redox reactions. This interplay between energy metabolism and ROS becomes most apparent during the aging process and in the onset and progression of many age-related diseases (i.e. diabetes, metabolic syndrome, ather...

Abstract Background Plant secondary metabolites or mixtures in extracts essential oils are well known to enhance the activity binary mixtures. The present study is first report that thymol synergistically additively enhances of P. ribesioides and isolated compounds against S. exigua larvae at sublethal doses. Results Thymol was synergistic when mixed with hexane extract; however, if extract lev...

The article " Modulation of Metabolic Detoxification Pathways Using Foods and Food-Derived Components: A Scientific Review with Clinical Application " is misleading in its title and the discussion does not fit this title. This narrative review article presents a comprehensive review of food and food components on specific metabolic detoxification pathways (phase I cytochrome enzymes, phase II c...

Brassilexin and sinalexin are among the most potent antifungal phytoalexins produced by crucifer plants. Nonetheless, the crucifer pathogen Leptosphaeria maculans(Desm.) Ces. et de Not. (asexual stage Phoma lingam(Tode ex Fr.) Desm.) is able to detoxify these phytoalexins. To understand and control these reactions, the elusive brassilexin and sinalexin detoxification pathways in L. maculans wer...

The continual suppression of emotions during fight or flight reactions results in atrophy and endogenous toxicosis in noradrenergic neurons. Toxic metabolites interfere with neurotransmission, causing depression. During periodic detoxification crises, excess norepinephrine floods synapses overexcite postsynaptic neurons, and cause symptoms ranging from mild anxiety to violent behavior. When tox...

Replacement of the photolabile and biodegradable isobutenyl substituent of pyrethroids with a dihalovinyl group often leads to improved insecticidal potency and enhanced photostability. This type of structural modification does not greatly alter the ease of detoxification in mammals since other sites in the molecule undergo metabolic attack. The available toxicological information on dihaloviny...
