A degrading bacterial strain F-3-4 for 2,6-Di-tert-butylphenol (2,6-DTBP) was isolated from biofilm in acrylic fiber wastewater treatment structures. By acclimation, its capacity for degradation of 2,6-DTBP was enhanced by 26%. It was identified as Alcaligenes sp. according to morphological, physiological

DBNP (2,6-di-tert-butyl-4-nitrophenol) has been reported as a potential contaminant in submarines. This yellow substance forms when lubrication oil mist containing the antioxidant additive 2,6-di-tert-butylphenol passes through an electrostatic precipitator and is nitrated. Percutaneous absorption of 14C-DBNP was assessed in the

Modulation of inhibitory synaptic transmission within the central nervous system contributes considerably to the anaesthetic effects of propofol and its analogues in vivo. We have studied the effects of the non-anaesthetic propofol analogue 2,6-di-tert-butylphenol on rat alpha(1)beta(2)gamma(2) GABA(A) receptors expressed

Amine or amide derivatives bearing the 2,6-di-tert-butyl phenol moiety are synthesised. Almost all are antioxidants, reduce acute inflammation and inhibit COX-1 and lipoxygenase activity. The most potent anti-inflammatory, COX-1 inhibitor and antioxidant agent, with low toxicity, is 2,6-di-tert-butyl-4-thiomorpholin-4-ylmethyl-phenol.
