The experience of the Dutch Medicines Evaluation Board as rapporteur in the concertation procedure has been a successful learning experience. We begin with informative discussions with the applicant in the presubmission phase, emphasizing close conta

The susceptibility of coumarins to alkaline hydrolysis, resulting in the formation of cis-coumarinate (and subsequently trans-coumarinate) polyanions is well known (Decker and Becker, 1922; Garrett et al., 1971; Mattoo, 1957; Bowden et al., 19611; Li

The protein binding of warfarin in serum has been studied by means of circular dichroism and equilibrium dialysis. Evidence was found that the N-B transition of albumin, occurring around physiological pH, takes place not only in solutions of pure alb

The pH-dependent distribution of weak acids in the octanol-water system was investigated. For a series of six 4-hydroxycoumarins, substituted at position 3, the apparent partition coefficient or the distribution coefficient, P app , was measured in t

The adsorptive behaviour of four supports in reversed-phase thin-layer chromatography was investigated. Oleyl alcohol was used as the stationary phase and methanol-water mixtures as the mobile phase. A series of 4-hydroxycoumarins were used as test c

The effect of chloride on the binding of warfarin to human serum albumin between pH 6 and 9.5 has been studied by circular dichroism and equilibrium dialysis. The molar ellipticity of the warfarin-albumin complex is hardly affected by chloride ions w
