Definitions
- Y represents one or more atoms or groups chosen from hydrogen, halogens and hydroxy, methyl and ethoxy groups
- Rx represents a hydrogen atom or a group (C ⁇ C ⁇ alkyl
- R 2 represents a hydrogen atom, a linear or branched (C- L -C ⁇ ) alkyl group, a hydroxy (C 1 -C 4 ) alkyl group, a (C 3 -C 7 ) cycloalkyl group, a group (C 3 -C 7 ) cycloalkyl (C ⁇ -Cs) - alkyl, a phenyl group, a pyridinyl group or a phenyl group (C- L -C ⁇ alkyl.
- the compounds of general formula (I) can exist in the form of bases or of addition salts with acids.
- PBR peripheral benzodiazepine receptors
- the latter can be prepared according to the following procedure, given by way of example.
- the synthesis of 7-chloro-5-methyl-4-oxo-3-phenyl-3, 5-dihydro-4i ⁇ -pyridazino [4, 5-jb] indole-1-acetonitrile is already described in international application PCT / FR00 / 00135.
- Example 1 (Compound No. 2 in the table below). 7-chloro-5-methyl-4-oxo-1- [2-oxo-2- (4-methylpiperazin-1-yl) ethyl] -3-phenyl-3, 5-dihydro-4iT-pyridazino hydrochloride [4 , 5-i] indole (1: 1).
- the hydrochloride is prepared using 0.89 g (0.002 mole) of base and 3 ml of a solution of hydrochloric acid (about 2M) in methanol. It is recrystallized from a mixture of dichloromethane and methanol.
- the hydrochloride is prepared using these 0.28 g (0.64 mmol) of base, dissolved in a mixture of propan-2-ol and methanol, and 10 ml of a hydrochloric acid solution (about 0 , 1N) in propan-2-ol, the product is recrystallized from propan-2-ol, it is collected by filtration, it is rinsed with diethyl ether and it is dried under reduced pressure. 0.145 g of hydrochloride is isolated in the form of a white solid. Melting point: 301-303 ° C.
- cC 3 H 5 denotes a cyclopropyl group
- cC 6 H 1 L denotes a cyclohexyl group
- C 6 H 5 denotes a phenyl group
- 2-C 5 H 4 N denotes a pyridin-2 group -yle.
- the affinity of the compounds of the invention for the peripheral benzodiazepine type receptors was determined.
- the p-site receptors can be selectively labeled in rat kidney membranes incubated in the presence of [ 3 H] Ro5-4864.
- the compounds have been the subject of an in vitro study as to their affinity for these receptors.
- the animals used are male Sprague Dawley rats (Iffa Credo) from 180 to 300 mg. After decapitation, the kidney is removed and the tissue is homogenized at 4 ° C using a Polytron TM homogenizer for 2 min at 6/10 of maximum speed in 35 volumes of 50 mM Na 2 HP0 4 phosphate buffer at pH adjusted to 7.5 with NaH 2 P0 4 .
- the membrane homogenate is filtered through gauze and diluted 10 times with buffer.
- the [ 3 H] Ro5-4864 (Specific activity: 70-90 Ci / mmol; New England Nuclear), at a concentration of 0.5 nM, is incubated in the presence of 100 ⁇ l of the membrane homogenate in a final volume of 1 ml of buffer containing the compound to be tested. After a 3 h incubation at 0 ° C, the membranes are recovered by filtration on Whatman GF / B TM filters which are washed with twice 4.5 ml of cold incubation buffer (0 ° C). The amount of radioactivity retained by the filter is measured by liquid scintigraphy.
- the concentration IC 50 a concentration which inhibits 50% of the specific binding.
- the IC 50 values of the most active compounds range from 5 nM to 20 nM.
- the compounds which can be used according to the invention are therefore ligands with high affinity for receptors of the peripheral benzodiazepine type. Study of neurotrophic activity.
- the lesion of the facial nerve by local freezing leads to degeneration of the distal part of the facial nerve and a loss of the blinking function of the eyelid.
- the products to be studied are administered intraperitoneally or orally 2 times a day with a delay of 6 to 8 hours, every day for 10 days (duration of the experiment).
- the first treatment is administered 30 minutes before the injury.
- Observation of the animals the recovery of the function of the eyelids in the injured animals is observed every day, once in the morning from D0 to D5 and 2 times (morning and evening with 6 to 8 h offset) from D6 to D10, before each treatment, according to a theoretical score ranging from 0 to 4.
- Score 0 open eye
- score 1 closed eye with a degree less than half of the eye
- score 2 degree of closure between 1/2 and 3/4
- score 3 degree of closure greater than 3/4
- score 4 eye completely closed.
- the results are expressed by the report of the AUC ("area under the curve") of the treated group and of the control group.
- the AUC ratios of the most active compounds are between 1.12 and 1.20. These compounds therefore increase by 12 to 20% the recovery of the palpebral reflex after lesion of the facial nerve.
- the facial nucleus is cut by the cryostat, in sections of 10 ⁇ m, in its entirety.
- the motor neurons are stained with cresyl violet and counted using Histo TM software (Biocom TM). In this model, the most active compounds increase neuronal survival by around 10 to 30%.
