- This administration is carried out according to methods well known to those skilled in the art, in particular those applied for the treatment of varicose diseases.
- Figure 1 schematically represents the activation cascade of the endothelial cell by hypoxia as well as its consequences in terms of adhesion and activation of neutrophils.
- FIG. 2 schematically represents the activation cascade of endothelial cells by hypoxia and its consequences at the level of the vascular wall.
- FIG. 3 represents the measurement of the respiratory activity of the mitochondria as a function of the addition of different active compounds.
- FIG. 4 schematically represents the chain of electron transporters at the level of the internal mitochondrial membrane.
- Endothelial cells by virtue of their location at the blood-tissue interface, are responsible for maintaining vascular homeostasis. They thus fulfill a whole series of functions and constantly interact with circulating leukocytes and smooth muscle cells (SMCs) in the media. Any disturbance in their metabolism can therefore lead to alterations in the functioning of the underlying tissues.
- SMCs smooth muscle cells
- the EC are the first to suffer from any modification of the blood flow and in particular from a reduction of this during stasis, which lead to a depletion of the intake oxygen and nutrients to tissues (Hinsha et al., 1988; Tsao et al., 1990).
- hypoxia which can in particular result from such a stasis, induces a significant activation of the ECs which release inflammatory mediators capable of activating neutrophils and inducing infiltration as well as growth factors for them. CML. This cascade of events ultimately leads to structural and functional changes in the venous wall. Effect of hypoxia on endothelial functions
- ECs isolated from the human umbilical vein are incubated in hypo under hypoxia. Under these experimental conditions, no mortality of the EC is observed during the first two hours of incubation. On the other hand, important modifications of their metabolism are observed: the EC are strongly activated by hypoxia in a similar way to the activation initiated by thrombin or histamine.
- the first sign of this activation is an increase in the cytosolic calcium concentration [Arnould et al. , 1992]. This increase is linked to a decrease in the ATP concentration. Calcium is an important secondary messenger in all cells.
- phospholipase A2 the first enzyme in a metabolic pathway leading to the synthesis of mediators of inflammation. This activation leads to an increased synthesis of prostaglandins [Michiels et al. , 1993]. It also induces the synthesis of platelet activating factors (Platelet Activating Factor (PAF)), which is a very powerful inflammatory mediator [Arnould et al. , 1993].
- PAF Platelet Activating Factor
- SMCs When synthetic, SMCs synthesize more components of the extracellular matrix and lose the expression of contractile filaments. Proliferation and increased synthesis of the components of the extracellular matrix lead to thickening of the venous wall while the loss of actin filaments accounts for the loss of overall contractility of the vein.
- the compounds of the invention there is for example an inhibition of the decrease in ATP content, of activation of phospholipase A2 and of the adhesion of PMNs induced by hypoxia. They are also capable of inhibiting the adhesion of PMNs to the endothelium of a complete human umbilical vein when the latter is incubated under hypoxic conditions. These results clearly indicate an important protective action of these compounds on the endothelium subjected to hypoxia.
- CE activation cascade induced by hypoxia is due to their inhibitory effect on the fall in ATP content. This decrease is the initiating event for the activation of
- CE because it is directly coupled to an entry of calcium ions into the cell.
- bilobalide Different concentrations of active compounds of the invention (bilobalide) were tested on the RCR of the mitochondria isolated from the brains of rats. Five concentrations were used: 4, 6, 8, 10 and 12 mg / kg of patient (rat) treated. The rats received these doses of bilobalide orally for 14 days.
- the mitochondria were isolated according to the method described by Nowicki et al.
- Mitochondrial respiration is measured in a Clark oxygen electrode connected to a recorder.
- the CPR represents respiratory control. It represents the relationship between oxygen consumption in the presence of endogenous substrates (glutamate / malate) and consumption after phosphorylation of ADP to ATP. This technique was developed by Chance and Williams (Nature, 175, pp. 1120-1121 (1955)). Dose-dependent effect is obtained with an increase in the RCR of 3.7 for the controls to a RCR of 4.6 for concentrations of 8 and 10 mg / kg. A maximum of 24% increase is obtained at 10 mg / kg. These results clearly show that this product is protected against mitochondrial respiration.
- the measurement on the complex I of the mitochondria was carried out by a prior sonication of the mitochondria in order to allow access of the assay substrates to the complex I.
- the latter is assayed according to the reduction of ferricytochrome C at 550 nm.
- the suspension of mitochondria being in a phosphate buffer of K at 25 nM, pH 7.4, containing MgCl2, 10 ⁇ M of cytochrome C and
- the activity of complex I was measured on mitochondria of rats treated for 14 days with 10 mg / kg of bilobalide per os and after a 15-minute ischemia of the brain. An activity of 36 mU / mg of protein is obtained for the control rats while the mitochondria of treated rats show an activity of 44 mU / mg of protein. There is therefore an important protection of the activity of the complex I of the mitochondria. The same protection of complex I is also observed on mitochondria isolated from the brains of rats which have not undergone a period of ischemia.
- the active compound of the invention (bilobalide) at concentrations of 8 mg / kg of patient (rat) was administered orally to rats for 14 days.
- the mitochondria of the liver of these rats were isolated according to the method described by Remacle (J. Cell. Biol. 79, 291, 1978).
- the respiratory activity of the mitochondria of treated rats showed an RCR of 13.25 compared to a RCR of 7.6 for the control rats.
- a 10-minute ischemia by perfusion was carried out on the livers in a medium consisting of 0.137 M NaCl, KC1 5.4 mM, MgSO 4 0.8 mM, glucose 11 mM, Na 2 HP0 3 0.34 mM, NaHC0 3 24.4 mM, KH 2 P0 4 6.35 mM and bilobalide 8 mg / 1.
- the medium is degassed beforehand under an atmosphere containing 95% of N2 and 5% of CO2.
- the mitochondria are isolated and their respiratory activity determined.
- the rats were given water for 14 days and the livers infused with the same solution as the tests. An RCR of 5.24 was observed for the mitochondria of treated rats and 3.73 for the control rats.
- the active compound of the invention (bilobalide) has an anti- ischemic which is revealed both in vitro (EC subject to hypoxia) and in vivo (hepatic and cerebral ischemia in treated rats) and that this activity is due at least in part to protection of the mitochondria which increase their respiratory activity and so their ATP synthesis.
- Each of the active compounds of the invention can increase the RCR of mitochondria isolated from the liver of untreated rats when these are preincubated for 1 hour in the presence of these drugs. They can therefore act directly on the mitochondria. It is very interesting to note that from these results, we can separate the drugs into two different classes: sweet clover extract, Ruscus extract, procyanolic oligomers and hydroxyethylrutosides which increase RCR by increasing the stage 3 of breathing (class II) while the bilobalide, aescin, naftoquinone and diosmin which constitute the drugs of class I increase the
- Mitochondria complex I was 58% inhibited by the presence of 0.5 mM Amytal. Under these conditions, the presence of the molecules at the indicated concentrations (incubation 60 minutes) shows a much less pronounced inhibition which was expressed as a percentage of protection compared to the mitochondria without drug, considered to have 0% of protection.
- the effect of the drugs was achieved on the activity of the adenine translocase of the mitochondria measured by the transport of ADP (C 14 ) in the mitochondria for 45 seconds.
- Another advantageous property of the compounds of the invention is that a synergistic effect can be obtained by the combination of different molecules acting on different targets, for example, a molecule acting on complexes I and III which results in a decrease in the stage 4 of mitochondrial respiration and one or more molecules acting on adenine translocase which results in an increase in stage 3 of mitochondrial respiration.
- the double protection thus obtained gives an advantageous and unexpected overall result, since it exceeds the maximum possible protection with each of the compounds.
- Two enzymatic targets of the active compounds have been identified. The action of the compounds on these two targets has the consequence of increasing the production of ATP by the mitochondria and of preventing this production from decreasing under ischemic conditions.
