英文摘要
The project described in this proposal is designed to define the
biochemical, biologic and pharmacologic significance of hematin-derived
anticoagulant (HDA). HDA produces prolongation of clotting times in vitro
and in vivo. HDA is a derivative or degradation product which is produced
when hematin is allowed to stand in solution or when it is infused into
rats. HDA will be purified and identified from in vitro and in vivo
sources by chromatographic and spectroscopic techniques. This will test
the hypothesis that HDA is a single derivative of hematin (heme) which is
capable of interacting with coagulation proteins to produce profound
functional effects. The mechanism of interaction of HDA with the specific
proteins fibrinogen, thrombin and factor VIII:C will be defined by
determining binding affinities and effects on enzymatic function with
natural and synthetic substrates. The specific techniques of UV-Vis
spectroscopy, equilibrium dialysis and antagonism with iron binding
compounds will test the hypothesis that iron or a trace metal is involved
in the interaction of HDA with clotting proteins. The production and
mechanism of HDA in vivo will be defined with isolated hepatic heme
metabolic systems and whole animals. This will test the hypothesis that
HDA is a metabolic product of heme and that the mechanism is identical to
that seen in vitro. Specific techniques involve radioisotope and
pharmacologic probes. Finally, the pharmacologic potential of HDA will be
determined by pharmacokinetic and efficacy studies utilizing radiolabelled
HDA and various routes of administration. Completion of these studies will
define the biochemical, physiologic and pharmacologic significance of HDA.
