- cycloalkyl a cyclic alkyl, for example, a C 3 - 6 cycloalkyl group represents a cyclopropyl, cyclobutyl, cyclopentyl or a cyclohexyl,
- the compounds of general formula (I) may contain one or more asymmetric carbon atoms. They can therefore exist in the form of enantiomers or diastereoisomers. These enantiomers, diastereoisomers, as well as their mixtures, including racemic mixtures are part of the invention.
- protection group Pg is intended to mean a group which allows on the one hand to protect a reactive function such as a hydroxy or an ine during a synthesis and on the other hand to regenerate the reactive function intact at the end of the synthesis.
- Examples of protective groups as well as methods of protection and deprotection are given in Protective groups in Organic Synthesis, Greene et al., 2nd Ed. (John Iiley & Sons, Inc., New York).
- a second subject of the present invention is processes for preparing the compounds of formula (I) according to the invention.
- the compounds of formula (I) are prepared from an amide of formula II by reacting it with a squarate derivative of formula III.
- the reaction can be carried out in an organic solvent such as tetrahydrofuran, usually at room temperature, the reagents being in stoichiometric quantity.
- the squarate derivative of formula III can be prepared from squaric acid (3, 4-dihydroxy-3-cyclobutene-1,2-dione) of formula V and an alcohol R40H of formula IV according to known methods of a person skilled in the art in particular according to the method described by Liebeskind et al J. Org. Chem. 1988, 53, 2482-2488 which consists in heating with an azeotropic distillation a solution of squaric acid of formula V and of alcohol R40H of formula IV in benzene.
- the meanings of RI, R2, R3 and R4 in each of the compounds of formulas II, III and IV are those indicated for formula (I).
- the compoé E of formula (I) may be modified to give another compound of formula (I) by heating a compound of formula (I) wherein R4 represents a methyl or ethyl group at a temperature of 50 to 100 ° VS with an alcohol of formula R40H in which R4 is as defined in formula (I), with the exception of methyl or ethyl in the presence of a base such as sodium or potassium carbonate.
- the amide compound of formula II can be prepared from tranexamic acid (trans-4- (aminomethyl) -cyclohexane-carboxylic acid) of formula X according to the process represented in scheme 2.
- the amine of the tranexamic acid of formula X is protected, according to methods known to a person skilled in the art, by a protective group Pg such as for example a carbamate, in order to provide the compound of formula IX which is then alkylated by the group R3 to give a compound of formula VIII.
- the alkylation reaction is carried out using a derivative R3Y in which R3 is as defined for the compound (I) and Y represents a bromine or an iodine in a solvent such as dimethylformamide in the presence of a base such as sodium or potassium hydride or carbonate.
- the compound of formula II is then prepared from the compound of formula VIII, after saponification, then formation of the amide according to conventional methods known to those skilled in the art.
- the amidation can be carried out by reacting the compound of formula VII with an amine NHR1R2 and a coupling agent such as BOP (benzotriazol-1-yloxytris (dimethyl-amino) phosphonium hexafluorophosphate) in a solvent such as dichloromethane or dimethylformamide, the protective group Pg of compound VI thus obtained is then deprotected according to methods known to those skilled in the art to give compound II.
- the deprotection can be carried out by means of trifluoroacetic acid optionally in dichloromethane.
- the meanings of RI, R2 and R3 in each of the compounds of formulas II, VI, VII and VIII are those indicated for formula (I).
- RI, R2 and R3 are those indicated for the formula '(I).
- M / e represents the molecular ion PF represents the melting point in ° C
- c-Hex represents a cyclohexyl group
- n-Pr represents a linear propyl group
- i-Pr represents an iso-propyl group
- c-Pr represents a cyclopropyl group
- the tests are carried out with a preparation of phosphodiésterase 5 (PDE 5) partially purified from human platelets.
- PDE 5 phosphodiésterase 5
- the purification of the enzyme is based on methods described in the literature (Grant, PG, and Colman, RW Biochemistry 1984, 23: 1801-1807; Simpson, AWM, Reeves, ML, and Timothy, JR Biochem. Pharmacol. 1988 , 37: 2315-2320; Ito, M., Nishikawa, M., Fujioka, M., Miyahara, M., Isaka, N., Shiku, H., and Nakano, T. Cellular Signaling 1996, 8: 575- 581).
- the enzyme preparation obtained after purification does not contain the other phosphodiesterase activities found in the platelets (ie PDE 2 and PDE 3).
- the enzyme preparation is also devoid of 5'-nucleotidase and / or phosphatase activities.
- the PDE 5 test used is based on the separation of cyclic GMP (cGMP, PDE 5 substrate) from 5'-GMP (product of the enzymatic reaction) by thin layer chromatography on polyethyleneimine (PEI) cellulose.
- the reaction medium contains 40 mM Tris-HCl (pH 7.5), 15 mM MgCl 2 , 1 mM EGTA, 0.5 mg / ml of bovine albumin, 0.25 ⁇ Ci of [ 3 H] -cGMP, 3 ⁇ M of cGMP, the inhibitor to be tested (concentration: 0 to 10 ⁇ M) and the enzyme in a total volume of 100 ⁇ l.
- the reaction is started by adding enzyme and is carried out at room temperature. The reaction is stopped after 30 min (conversion rate of 10-15%) by introducing the stoppered test tube (Eppendorf polypropylene cone) into a boiling water bath for 3 minutes.
- an aliquot of the sample (10 ⁇ l) is deposited at the bottom of a plastic PEI cellulose plate (Merck) on which cGMP and 5'-GMP (10 ⁇ g of each entrainer) have been deposited beforehand.
- the plate is developed with a 450 mM LiCl solution.
- the strip of PEI cellulose containing the 5'-GMP is cut and the nucleotide is quantitatively extracted with 2 ml of a 16 M solution of formic acid and 2 M of ammonium formate in a counting flask.
