Abstract
2-Amino-1 -(methoxyphenyl)-1 -ethanol derivatives of the formula <IMAGE> (wherein Z is C4-C8-alkyl or hydroxyalkyl group having a branched hydrocarbon chain) and their addition salts, are useful as vasodilating agents. Some exhibit antidepressant and sedative effects also.
Description
SPECIFICATION
Medicaments belonging to the family of 2-amino-i -(methoxyphenyl)-1 -ethanol derivatives
This invention relates to the use of new medicaments, which belong to the 2-amino-1-phenyl-1ethanols family, namely 2-amino-1-(methoxyphenyl)-1-ethanol derivatives which are useful in therapeutics as agents acting on the central nervous system (CNS) and on the cardiovascular system.
It is known from FR-A-2 460 668 that 2-amino-l-phenyl-l -ethanol derivatives of the general formula
Wherein R is H, CH3, OCH3; R1 is in particular C1-C4-alkyl; and R2 is C5-C8-alkyl and may represent in certain conditions CH(CH3)2 or C(CH3)3] have been recommended as substances useful in therapeutics. However FR-A-2 460 668 neither discloses nor suggests the interest, from a therapeutical point of view, of the methoxy compounds (R = OCH3).
It is known that the 1-(2-,3- and 4-methoxyphenyl)-2-tertiobutylamino-1-ethanols have been disclosed in GB-A-1 043 519 as intermediate compounds in the synthesis of anti-diuretic substances, namely the N-methyl-N-tertiobutyl- 1-(2-, 3- and 4-methoxyphenyl)-1 -ethanols.
Moreover dimethoxyphenyl compounds, which are structurally different from the monomethoxyphenyl derivatives according to the invention, were already disclosed in the past.
In particular FR-A-1 372 742 recommends the 1-(3,4-dimethoxyphenyl)-2-tertiobutylamino-1ethanol as an agent which inhibits fi-adrenergic receptors, and FR-M-2864 recommends 1-(2,5 dimethoxyphenyl)-2-alkylamino-1-propanols as cardiac antiarythmia agents.
It has been found now that some 2-amino-1-(methoxyphenyl)-1-ethanol derivatives which can be included within the definition of the above formula lo, but without being specifically disclosed as medicaments, exhibit beneficial therapeutical properties which are particularly interesting with respect to certain diseases of the CNS and mainly to diseases of the cardiovascular system.
According to the invention are recommended as drugs, 2-amino-1-(methoxyphenyl)-1-ethanol derivatives of the formula
wherein Z is a C4-C8-alkyl group with a branched hydrocarbon chain, or a C4-C8-hydroxyalkyl group with a branched hydrocarbon chain, said drugs which are new, being characterized in that they are selected from the group consisting of::
a) the 1 -(2-methoxyphenyl), 1 -(3-methoxyphenyl)- and 1 (4-methoxyphenyl)-2-tertiobutylam- ino-1-ethanols and their addition salts,

The compounds according to the invention can be prepared according to a method known per se by application of classical reaction mechanisms.The method which is recommended here comprises subjecting a N-(methoxyphenyl)-amine derivative to a reduction reaction with NaBH4 or KBH4, according to the following reaction:
This reaction is carried out in an inert solvent selected from C1-C2-alcohols, at a temperature comprised between - 5'C and 0 C (for at least 0.30 h), in a proportion of 1 to 1.3 mol of borohydride selected from NaBH4 and KBH4 for 1 mol of N-(methoxyphenacyl)-amine of the formula II.
Compounds of the formula II, used here as starting material, can be prepared according the method given in French patent application No 83 1 8868 of the Applicant.
All the compounds according to the invention act as vasodilating agents, some of them exhibit interesting effect on the CNS. In particular (i) CRL 40-832 (example 5) has at a lower dose antidepressant effects (antagonism of the hypothermiae induced by the apomorphine, reserpine and oxotremorine), exhibits at a higher dose sedative effects, and decreases the intergroup aggressiveness of male mice from the dose of 1 mg/kg l.P., and, (ii) CRL40819 (example 4) decreases the intergroup aggressiveness of male mice at the dose of 8 mg/kg l.P.
According to the invention a therapeutical composition is provided which comprises, in association with a physiologically acceptable excipient, at least a 2-amino-1-(methoxyphneyl)-1ethanol or one of its addition salts, as the active ingredient.
Of course, in a composition of this type the active ingredient which is selected from the group consisting of 2-amino-1-(methoxyphenyl)-1-ethanol derivatives and non-toxic addition salts thereof is present in a pharmaceutially effective amount.
Further advantages and characteristics of the invention will be understood more clearly on reading the following description of preparative examples and results of pharmacological assays; these data as a whole do not imply a limitation but are given by way of illustration.
PREPARATION I
Obtention of I -(4-methoxyphenyl)-%f( 1, 3-dimethylbutyl)aminol- 1-ethanol
(Example 3; Code No: CRL 40 800)
26.1 g (0.0914 Mol) of N-(4-methoxyphenacyl)-1,3-dimethylbutylamine hydrochloride (Code
No: CRL 40 799; MP = 1 90"C with decomposition) are dissolved in water. NaCO3 is added up to a pH of 11. The mixture thus obtained is extracted with 500 ml of diethylether, the ethereal phase is washed with H20, dried over MgSO4 and filtered in order to recover the filtrate which contain the N-(4-methoxyphenacyl)-1 ,3-dimethylbutylamine.
The filtrate is evaporated to dryness and the evaporation residue is taken up with 280 ml of CH3OH then cooled at - 5"C before addition of 3.5g (0.0914 mol) of NaBH4. The reaction mixture is left to evolve until disappearing of the phenacyl derivative as checked on TLC (eluent: CH3C6H-CH3COCH3-NH40H(30 :70:2) v/v; support: silica gel plate; revelation: U.V. radiation + Draggendorf reagent]. After addition of acetic acid, the reaction mixture is evaporated to dryness; the evaporation residue is taken up with 500 ml of water, adjusted to pH 11 and extracted with diethylether.
The ethereal phase is washed with water, dried over MgSO4 and filtered in order to recover the filtrate. From the filtrate the expected hydrochloride salt is precipitated by means of a 15 ml solution of HCI 7N in ethanol. Recrystallization from an acetone-ethanol (1:1) v/v mixture gives 7 g (yield: 26%) of CRL 40 800. M.P. = 177'C.
% N measured = 4.86 % Analysis % N theoretical = 4.86 % PREPARATION II Obtention of 1 -(4-meThoxyphenyl)-2-U', tr-dimethyl- - h ydroxyethyl)-amino]- 1- ethanol hydrochloride, alternative nomenclature: 1-(4-methoxyphenyl)-2-[2-(2-hydroxymethyl- propyl)-amino]-1-ethanol.
(Example 2; Code No: CRL 40 798)
50 g (0.218 mol) of 4-methoxyphenacyl bromide (in solution in 200 ml of chloroform) are poured into a solution of 77.6 g (0.872 mol) of 2-(2-hydroxymethyl-propyl)-amine in 100 ml of methanol. The reaction mixture is heated under reflux for 2 h, cdoled, evaporated to dryness, and the evaporation residue is taken up with 500 ml of water and extracted with ethyl acetate.
The ethyl acetate phase is washed with water and extracted by a mixture consisting of 500 ml of water and 22 ml of concentrated hydrochloric acid (d = 1.19). The aqueous phase is washed with CH3CO2C2H5 alcalinized up to pH 11 with K,CO,. extracted with CH3CO2C2H5. The organic phase is washed with water, dried over MgSO4 and filtered. The filtrate which comprises the N (4-methoxyphenacyl)-N-2-(2-hydroxymethyl-propyl)amine of the formula
is evaporated to dryness.
The evaporation residue is dissolved in 680 ml of methanol, cooled at - 5'C and 9.1 g (0.24 mol) of NaBH, are added. The reaction is left to evolve until total disappearing of the phenacyl compound as checked on TLC (as indicated above in Preparation I), then 14.5 ml of acetic acid are added and the resulting mixture is evaporated to dryness. The evaporation residue is taken up with 300 ml of water. After extraction with CH3CO2C2H5, washing the ester phase with water, drying over MgSO4 and filtration for removing MgSO4, the expected hydrochloride salt is obtained by means of a 31 ml solution of HO 7N in ethanol.Recrystallization from an acetonemethanol (1:1) v/v mixture gives 5 g (overall yieid: 8%) of CRL 40 798 M.P. = 182"C.
% N measured = 5.00 % Analysis % N theoretical = 5.08 % PREPARATION III Obtention of 1 (3-methoxyphenyl)-2-tertiobutylamino- methanol methanesulfonate.
(Example 5; Code No = CRL40 832)
NaBH4 (0.12 mol) is introduced at - 5"C into a solution of 0.10 mol of N-(3-methoxyphenacyl)-tertiobutylamine in methanol. The reaction is left to evolve until total disappearing of the phenacyl compound as checked on TLC (as indicated above in Preparation I), then acetic is added and the resulting mixture is evaporated to dryness. The evaporation residue is taken up with H20; after extraction with either, washing the ethereal phase with water, drying over
MgSO4 and filtration in order to discard MgS04, the expected methanesulfonate salt is obtained by addition of methanesulfonic acid. Recrystallization from an acetone-methanol (1 )v/v mixture CRL40832 with a yieid of 35% M.P. = 151 C.
Results of assays, which have been carried out, are summed up hereinafter.
A-CRL 40 774 (Example 1)
On nembutal anesthetized dog, it is observed that CRL 40 774 administered by l.V. route exhibits a femoral vasodilating action at a dose of 10 mg/kg (+ 36%). As from 1 mg/kg
CRL 40 74 presents an important bradycardial effect, and as from 5 mg/kg an hypotensive action. It seems that CRL 40 774 possesses a fli action, since, besides its own effect, it highly decreases the isoprenaline ss-stimulating action; moreover its femoral vasodilating action seems to be of the ss2+ type.
On awake normotensive dogs CRL40774 has a slight hypotensive effect (- 18%) at a dose of 10 mg/kg per os.
On awake and spontaneously hypertensive rats, the minimal hypotensive dose of CRL 40 774 per os is 5 mg/kg.
B--CRL 40 798 (Example 2)
CRL 40 798 exhibits on the nembutal anesthetized dog a femoral vasodilating effect. It seems to present a ssl- effect.
C-CRL 40 800 (Example 3)
CRL 40 800 exhibits a femoral vasodilating action as from the dose of 1 mg/kg. It seems to present a ss+ effect.
D-CRL 40 819 (Example 4)
CRL 40 819 administered intraduodenally to nembutal anesthetized dogs. It exhibits an important hypotensive action as from the dose of 20 mg/kg. This product seems to have a fl effect. Moreover it decreases aggressiveness as from 8 mg/kg l.P. on male mice according to the intergroup aggressiveness test.
E-CRL 40 832 (Example 5)
CRL 40 832 exhibits, on one hand, at lower doses, effects of the antidepressive type (antagonism of hypothermia induced by apomorphine, reserpine or oxotremorine), and, on the other hand, at higher doses, effects the sedative type which can explain only partially the clear decrease of aggressiveness.
Moreover, CRL 40 832 administered intraduodenally to anesthetized dogs at doses from 0.1 to 20 mg/kg exhibits a femoral vasodilating activity as from 0.1 mg/kg. the effect is proportionnal to the dose used and has a duration higher than 1 hour. It is also observed that, at lower doses, the compound induces tachycardia and vertebral vasodilatation which are both moderate. It seems that CRL 40 832 has a ssl~ effect. This product is useful in particular as periphereal vasodilating agent.
