Enzymatic synthesis and chromatographic purification of lignan glucuronides.
Enterolactone, enterodiol and secoisolariciresinol were conjugated with glucuronic acid by solubilized rabbit liver microsomal UDP-glucuronyltrasnferase. The monoglucuronide conjugate of all three substrates was formed and its identity confirmed by nuclear magnetic resonance (NMR) spectroscopy. Analytical high pressure liquid chromatography (HPLC) and NMR spectroscopy indicated conjugation with glucuronic acid to occur at several positions in the molecule. The enzymatic conjugation was monitored by analytical capillary isotachophoresis (ITP). The Km-values for enterlactone, enterodiol, and secoisolariciresinol were calculated to be 0.30, 0.23, and 0.22 mmol/l respectively.
The effect of high dose oxprenolol on stress-induced physical and psychophysiological variables.
The effects of oral oxprenolol (480 mg) and lorazepam (2 mg) on skin conductance, reaction time, critical flicker frequency and self-rating visual analogue scales for anxiety, sedation and concentration were investigated in 6 healthy male volunteers. Oxprenolol exerted a central action similar to lorazepam as shown by a significant lowering of skin conductance and decrease in the number of spontaneous fluctuations during stress, impaired critical flicker frequency and decrease in alertness with reduced concentration.
