Definitions
- the present invention relates to novel nitric esters of 1,2-benzo-isothiazolyl-3 (2H) one-1,1-dioxide substituted in position 2, a process for the preparation of these esters, and medicaments which contain these esters.
- These compounds have a very specific vasodilatory activity on the vessels and are therefore effective in the therapy and prevention of cardiovascular disorders, in tissue ischemia, in angina pectoris and in hypertension.
- Nitric esters such as trinitroglycerin or i ⁇ osorbide dinitrate, have been used for a long time for the treatment of angina pectoris and for other cardiovascular disorders because they have a decreasing vasodilatory activity. notably the pre-charge of the heart from which it results a less need for oxygen for this organ.
- these compounds present the clinical problem of developing tolerance during chronic administration.
- EP-0473027, EP-0490183, EP-0171977 and EP-0210581 describe nitrates derived from pyridinecarboxyamides, benzoxazinones, phthalimides and 1,4-benzodioxanes respectively.
- EP-0473027, EP-0490183, EP-0171977 and EP-0210581 describe nitrates derived from pyridinecarboxyamides, benzoxazinones, phthalimides and 1,4-benzodioxanes respectively.
- phthalimides 1,4-benzodioxanes
- the present invention includes a series of new nitric esters in which the nitrate group is linked by an alkyl chain substituted or not for the nitrogen atom of a group of 1,2-benzo-isothiazolyl-3 (2H) one-1 , 1-dioxide. These compounds have a high vasodilating activity, have a lower degree of tolerance and can be prepared on an industrial scale; they are therefore satisfactory from the point of view of practical use.
- the compounds which are the subject of the present invention are nitric esters of 2-alkyl-1,2-benzo-isothiazolyl-3 (2H) one-1,1-dioxide of general formula (I)
- Y is a substituted cycloalkyl group, or a group
- R is a hydrogen atom, a methyl radical, a 2,4-dichlorophenyl radical or a nitrate residue
- R ' is a hydrogen atom or a methyl radical, m is an integer between 0 and 5, n is an integer between 0 and 1.
- the compounds of general formula (I) can be prepared by treatment of an alcohol of general formula (II) or of a halogenated compound of general formula (III)
- the starting materials of general formula (II) are known and can be prepared by standard methods from commercial reagents.
- 2-hydroxymethyl-1,2-benzo-isothiazolyl-3 (2H) one-1,1-dioxide was prepared according to the Choi, Lee and Yoon method described in J. Heter. Chem., 26, (1989), 1073.
- the other 2-hydroxyalkyl-1,2-benzo-isothiazolyl-3 (2H) one-1,1-dioxides can also be obtained by known standard methods, such as by example by reaction between the sodium salt of 1,2-benzo-isothiazolyl-3 (2H) one-l, l-dioxide and the corresponding halogen derivative of general formula (iv);
- R, R ', m and n have been defined above and where X represents an oxygen atom in a manner similar to that described by H.L Rice and G.R Pettit in J. Amer. Chem. Soc, 76, (1974), 302.
- the subject of the invention is also a medicament comprising at least one compound of general formula (I) according to claim 1.
- This drug has a vasodilating effect and can be used for the preventive or curative treatment of cardiovascular diseases.
- This medication is particularly suitable for the treatment of cardiac or tissue ischemia, angina pectoris, heart failure and hypertension.
- the compounds (I) of the present invention can be administered alone, but they will generally be administered in admixture with a pharmaceutical vehicle selected according to the route of administration and standard pharmaceutical practice.
- they can be administered orally either in the form of tablets containing excipients such as starch or lactose, or in capsules either alone or mixed with excipients or in the form of syrups or suspensions containing coloring agents or flavorings. They can also be injected parenterally, such as, for example, intramuscularly, intravenously or subcutaneously.
- parenteral administration When parenteral administration is involved, they will preferably be used in the form of a sterile aqueous solution which may contain other solutes, such as for example a salt or glucose, intended to make the solution isotonic.
- a sterile aqueous solution which may contain other solutes, such as for example a salt or glucose, intended to make the solution isotonic.
- the medicaments may contain an amount of any of the compounds of general formula (I), so that the level of the administered dose is between 0.001-10 mg / kg.
- the quantity of active principle which each of the dosage forms may contain may be approximately between 0.05 mg and 1 g.
- intravenous administration can include a drip for continuous dosing.
- the relaxing power of the compounds of general formula (I) is determined by means of "in vitro" tests carried out on rat aorta rings contracted by norepinephrine.
- the thoracic aorta is extracted and cut into rings 3 mm wide. These rings are suspended in an organ bath filled with Krebs liquid at a constant temperature of 37 ° crossed by a current of 0 2 / C0 2 (95/5). Once balanced, the aorta contracts under the action of norepinephrine; finally, the relaxation obtained by increasing concentrations of the compounds (I) of the present invention is observed.
- the relaxing power of the various compounds is expressed in IC so , that is to say, the concentration at which a relaxation of 50% of the contraction induced by norepinephrine is reached.
