-Six phenols [2(3)-t-butyl-4-hydroxyanisole (BHA), 2-t-butylphenol, 4-methoxyphenol, 4-methylmercaptophenol, t-butylhydroquinone and 2,6-di-tbutylphenol] previously shown to be inhibitors of benzo(a)pyrene-induced neoplasia, were examined for their ability to induce in vivo changes in hepatic mono-oxygenase and detoxication enzyme activities, and to act as mono-oxygenase inhibitors when added i...
A convenient protocol has been developed to fabricate well-defined nanorods of a photochromic molecule N-(3,5-di-tert-butylsalicylidene)-4-aminopyridine (DBSAP) by a laser ablation method. Reversible and fatigue-resistant optical switching and SHG activity were demonstrated. Interestingly, it was observed that DBSAP nanorods exhibit intermediate photochromic properties compared to solution and ...
Some of the anticarcinogenic effects of 2(3)-tert-butyl-4-hydroxyanisole (BHA) are attributable to the induction of detoxifying enzymes in the liver and peripheral tissues. This study was designed to determine if the tissue specificity of enzyme induction could be manipulated by structural modification of BHA. The induction of glutathione S-transferases and quinone reductase (EC 1.6.99.2) by th...
Palladium-catalyzed N-tert-prenylations of indoles, tricarbonylchromium-activated indoles, and indolines that occur in high yields (up to 94%) with high tert-prenyl-to-n-prenyl selectivity (up to 12:1) are reported.
A significant problem associated with the commercial acceptance of biodiesel is poor oxidative stability. This study investigates the effectiveness of various natural and synthetic antioxidants [a-tocopherol (a-T), butylated hydroxyanisole (BHA), butyl-4-methylphenol (BHT), tert-butylhydroquinone (TBHQ), 2, 5-di-tert-butylhydroquinone (DTBHQ), ionol BF200 (IB), propylgallate (PG), and pyrogallo...
Several classes of compounds are able to induce a spectrum of drug-metabolizing enzymes without inducing cytochrome P450s. Examples include antioxidants such as tert-butyl-4-hydroxyanisole and its metabolite tert-butylhydroquinone, dithiolthiones such as oltipraz, and N-heterocycles such as 1,7-phenanthroline. The events associated with induction of UDP-glucuronosyltransferases (UGT), glutathio...
