Fluorescence investigation of affinity interaction between bovine serum albumin and triazine dye in reversed micelles.

The effect of Cibacron Blue 3GA (CB) on the fluorescence emission spectra of bovine serum albumin (BSA) was investigated in cationic reversed micelles formed with cetyltrimethylammonium bromide (CTAB) compared with that in aqueous phase. The anionic CB had electrostatic interactions with cationic CTAB and affinity interactions with BSA in the reversed micelles. The addition of CB in the reversed micellar phase led to a great decrease in the fluorescence intensity of BSA and a remarkable red shift of the wavelength of emission maximum (lambda(max)). The fluorescence intensity of BSA decreased and the lambda(max) decreased 5 nm (blue shift) without the addition of CB in the reversed micellar phase. The fluorescence intensity of BSA with the addition of CB had the strongest value in the aqueous phase with the presence of CTAB, a less strong value in the reversed micellar phase, and a weak value in the aqueous phase without the presence of CTAB. The increase in lambda(max) of BSA with the addition of CB in the reversed micellar phase might indicate the decrease in the hydrophobic microenvironment of the Trp residue of BSA, contrary to those microenvironments in the absence of CB.

The metabolic fate of a herbicidal methylmercapto-s-triazine (cyanatryn) in the rat.

1. A major route of metabolism of the methylmercaptotriazine herbicide cyanatryn involves S-oxygenation. 2. The S-oxide reacts spontaneously with glutathione affording a conjugate, which is eliminated in the bile, and a mercapturic acid which is eliminated in the urine. 3. A small proportion of the administered dose was covalently bound to a component of the blood, probably haemoglobin. This was shown to be dependent on the formation of the S-oxide and on the species of animal studied. 4. No reactivity of the S-oxide towards DNA in vivo or in vitro could be demonstrated.
