Reaction g) of an aminoalcohol VI with a compound of the formula HO--M.sup.6 --T--Q leads to an aminoether I in which L--M is a group L.sup.5 --O--M.sup.6 in which L.sup.5 and M.sup.6 are as defined above.

Reaction h) of an aminoalcohol VI with a chloride VII leads to an ether I in which L--M is a group L.sup.5 --O-pyridylene. It can be carried out in the presence of a base such as KOH and K.sub.2 CO.sub.3 in the presence of a crown ether such as dicyclohexano-[18]-crown-6 in a solvent such as toluene while heating.
Reaction i) of an acid addition salt of the amine VIII with an acid chloride ClC(O)--Q.sup.6 leads to the corresponding aminoketone I in which T--Q stands for C(O)--Q.sup.6. It can be performed in the presence of aluminium chloride in carbon disulphide while heating.
Reaction j) of a diamine IX with a halide ClS(O).sub.2 --Q, ClC(O)--Q or BrCH.sub.2 C(O)--Q leads to the corresponding amine I in which T--Q stands for S(O).sub.2 --Q, C(O)--Q or, respectively, CH.sub.2 C(O)--Q. It can be carried out in a solvent such as methylene chloride in the presence of di-isopropyl-ethylamine (Hunig base).
Process variant k) can be a Grignard reaction between an aldehyde X and a halide such as Q--MgBr. Where Q is optionally substituted phenyl, a halide such as Q--Br in THF can firstly be reacted with butyllithium in hexane and the resulting compound Li--Q can be reacted with an aldehyde X at a low temperature such as about -78.degree. C. to give the corresponding ketone I.

a) The transformation of a cyano group which is present as a substituent on an alkyl group A.sup.2 and/or a phenyl group Q into the carbamoyl group can be carried out using a hydrogen peroxide solution in the presence of potassium carbonate in DMSO at about 0.degree. C.
b) The hydrolysis of an alkanoylamino group which is present as a substituent on a group Q' to the amino group can be effected using hydrochloric acid in ethanol.

The invention is also concerned with the compounds of formula I and their salts for use as therapeutically active substances, antimycotically-active and cholesterol-lowering medicaments containing a compound of formula I or a salt thereof as the active ingredient, if desired together with a therapeutically inert carrier, as well as the use of the compounds of formula I and the salts thereof for the production of the aforementioned medicaments.
Cholesterol is a major component of atherosclerotic plaques. The connection between coronary heart disease (CHD) and high LDL cholesterol concentrations in plasma (LDL=low density lipoproteins) and the therapeutic advantage of lowering elevated LDL concentrations are today generally recognized (Gotto et al., Circulation 81, 1990, 1721-1733; Stein et al., Nutr. Metab. Cardiovasc. Dis. 2, 1992, 113-156). Atherosclerotic plaques can grow and lead to occlusion of blood vessels resulting in an ischaemia or an infarct. Studies with respect to primary prophylaxis have shown that a lowering of the LDL concentrations in plasma reduces the frequency of non-fatal incidences of CHD, while the overall morbidity remains unchanged. The lowering of the LDL cholesterol level in plasma of patients with clinically confirmed CHD (secondary intervention) reduces the CHD-mediated mortality and morbidity; the metaanalysis of different studies shows that this decrease is proportional to the reduction of the LDL cholesterol.
The clinical advantage of cholesterol lowering is even greater for patients with confirmed CHD than for asymptomatic persons with hypercholesterolemia. For the majority of patients who had survived a myocardial infarct as well as for patients suffering from angina pectoris or another atherosclerotic disease treatment with a lipid lowering agent is advisable, in which case a LDL cholesterol concentration of 2.6 mmol/l should be striven for.
Preparations such as cholanic acid sequestrating preparations, fibrate, nicotinic acid, probucol as well as the statins (HMG-Co-A reductase inhibitors) such as lovastatin and simvastatin are used for usual standard therapies. A new cholesterol-lowering medicament would be of considerable benefit for CHD patients having a high LDL cholesterol level and in which the striven-for value of 2.5 to 3.0 mmol/l can not be achieved with statins.
Further, the statins have undesired side effects. They inhibit cholesterol production in an early phase of the synthesis cascade, with the formation of non-sterolic isoprenoids also being inhibited. The latter are indispensable for cell functions. The regulation of the cell cycle, the modification of albumins and the transport of electrons in the carbon dioxide chain can therefore be influenced by statins.
For this reason a number of experiments have been undertaken to find plasma-cholesterol lowering medicaments which inhibit the cholesterol synthesis on the one hand after the farnesyl-pyrophosphate stage in order not to inhibit the formation of non-sterolic isoprenoids and on the other hand prior to lanosterol in order to avoid an accumulation of sterol intermediates. The compounds described in European Patent Application No. 636 367, which inhibit 2,3-oxidosqualene-lanosterol cyclase (OSC) and which lower the total cholesterol in plasma, belong to these substances.
The present compounds of formula I inhibit cholesterol synthesis and reduce the total cholesterol in plasma. They can therefore be used in the therapy and prophylaxis of hypercholesterolemia, hyperlipemia and arteriosclerosis. In contrast to known compounds they are tolerated better and are more active. Further, they can be used in the therapy of mycoses and hyperproliferative disorders. The following tests were carried out in order to verify the activity of the compounds of formula I and their salts.
Inhibition of Human Liver Microsomal 2,3-Oxidosqualene-lanosterol Cyclase (OSC)
Liver microsomes from a healthy volunteer were prepared in sodium phosphate buffer (pH 7.4). The OSC activity was measured in the same buffer which also contained 1 mM EDTA and 1 mM dithiothreitol. The microsomes were diluted to 0.8 mg/ml protein in cold phosphate buffer. Dry [.sup.14 C]R,S-monooxidosqualene (MOS; 12.8 mCi/mmol) was diluted to 20 nCi/.mu.l with ethanol and mixed with phosphate buffer-1% BSA (Bovine Serum Albumin). A stock solution of 1 mM test substance in DMSO was diluted to the desired concentration with phosphate buffer-1% BSA. 40 .mu.l of microsomes were mixed with 20 .mu.l of the solution of the test substance and the reaction was subsequently started with 20 .mu.l of the [.sup.14 C]R,S-MOS solution. The final conditions were: 0.4 mg/ml of microsomal proteins and 30 .mu.l of [.sup.14 C]R,S-MOS in phosphate buffer, pH 7.4, containing 0.5% albumin, DMSO <0.1% and ethanol <2%, in a total volume of 80 .mu.l.
After 1 hour at 37.degree. C. the reaction was stopped by the addition of 0.6 ml of 10% KOH-methanol, 0.7 ml of water and 0.1 ml of hexane:ether (1:1, v/v) which contained 25 .mu.g of non-radioactive MOS and 25 .mu.g of lanosterol as the carrier. After shaking 1 ml of hexane:ether (1:1, v/v) was added to each test tube, these were again shaken and then centrifuged. The upper phase was transferred into a glass test tube, the lower phase was again extracted with hexane:ether and combined with the first extract. The entire extract was evaporated to dryness with nitrogen and the residue was suspended in 50 .mu.l of hexane:ether and applied to a silica gel plate. Chromatographic separation was effected in hexane:ether (1:1, v/v) as the eluent. The Rf values for the MOS substrate and the lanosterol product were 0.91 and, respectively, 0.54. After drying radioactive MOS and lanosterol were observed on the silica gel plate. The ratio of MOS to lanosterol was determined from the radioactive bands in order to determine the OSC inhibition.
The test was carried out on the one hand with a constant test substance concentration of 100 nM and the percentage OSC inhibition against controls was calculated. In addition, the test was carried out with different test substance concentrations and subsequently the IC.sub.50 value was calculated, i.e. the concentration required to reduce the conversion of MOS into lanosterol to 50% of the control value. The results are given in the following Table:

Male golden hamsters kept individually were pre-treated for 7 days with a diet containing grated coconut (40 cal.% fat). The animals were then divided into groups each comprising 5 animals. During the treatment the animals were maintained on the same diet. Each test substance was firstly homogenized in 9 ml of water and subsequently mixed with the milled diet. The controls received only feed converted into a paste with water. The animals were treated for 10 days with a test substance dosage of 200 .mu.mol (about 70-120 mg/kg/day). Blood samples (200 .mu.l) were removed via the jugular vein under light anaesthesia on the last day of the pre-treatment and one day after the last administration of test substance. The plasma cholesterol concentration was determined using a colorimetric enzyme method. The plasma lipoproteins were separated by exclusion chromatography (Hennes et al., Science Tools, 36, 1992, 10-12). The total cholesterol was determined in each fraction using a fluorometric enzyme method (Gamble et al., J. Lipid Res., 19, 1978, 1068-1071) in order to calculate the amount of cholesterol in the LDL and HDL fractions. The activity on plasma cholesterol and LDL and HDL cholesterol, expressed in percent of the control animals, for the products of Examples 8a and 12 is reproduced in the following Table:
______________________________________Example 8a 12______________________________________Total cholesterol -30% -25% LDL cholesterol -51% -54% HDL cholesterol -18% -23%______________________________________
As already mentioned, the compounds of formula I and their pharmaceutically acceptable acid addition salts have, moreover, valuable antifungal properties. They are active against a large number of pathogenic fungi which cause topical and systemic infections, such as Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus.
Antifungal Activity in Vitro
The compounds were tested for antifungal activity against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus using a microdilution method on microtitre plates (96 wells per plate). Yeast supplemented with 1% glucose and 0.25% di-potassium phosphate was used for the three fungal strains. The fungal cells were inoculated at 3.times.10.sup.4 CFU (Colony Forming Unit) in 1 ml of medium per well. The medium contained increasing concentrations of test substance. After incubation at 27.degree. C. for 24 or 48 hours the turbidity in each well was measured by a microtitre plate reader. The growth inhibition was calculated in comparison to a control (without test substance). The IC.sub.50 value given in the following Table is the concentration of test substance at which the growth is inhibited by 50%.

The compounds of formula I and their pharmaceutically acceptable acid addition salts can be used as medicaments, e.g. in the form of pharmaceutical preparations for enteral, parenteral or topical administration. They can be administered, for example, perorally, e.g. in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions, rectally, e.g. in the form of suppositories, parenterally, e.g. in the form of injection solutions or infusion solutions, or topically, e.g. in the form of ointments, creams or oils.
The production of the pharmaceutical preparations can be effected in a manner which will be familiar to any person skilled in the art by bringing the described compounds of formula I and their pharmaceutically acceptable acid addition salts, optionally in combination with other therapeutically valuable substances, into a galenical administration form together with suitable, non-toxic, inert, therapeutically compatible solid or liquid carrier materials and, if desired, usual pharmaceutical adjuvants.
Suitable carrier materials are not only inorganic carrier materials, but also organic carrier materials. Thus, for example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts can be used as carrier materials for tablets, coated tablets, dragees and hard gelatine capsules. Suitable carrier materials for soft gelatine capsules are, for example, vegetable oils, waxes, fats and semi-solid and liquid polyols (depending on the nature of the active ingredient no carriers are, however, required in the case of soft gelatine capsules). Suitable carrier materials for the production of solutions and syrups are, for example, water, polyols, sucrose, invert sugar and the like. Suitable carrier materials for injection solutions are, for example, water, alcohols, polyols, glycerol and vegetable oils. Suitable carrier materials for suppositories are, for example, natural or hardened oils, waxes, fats and semi-liquid or liquid polyols. Suitable carrier materials for topical preparations are glycerides, semi-synthetic and synthetic glycerides, hydrogenated oils, liquid waxes, liquid paraffins, liquid fatty alcohols, sterols, polyethylene glycols and cellulose derivatives.
Usual stabilizers, preservatives, wetting and emulsifying agents, consistency-improving agents, flavour-improving agents, salts for varying the osmotic pressure, buffer substances, solubilizers, colorants, masking agents and antioxidants come into consideration as pharmaceutical adjuvants.
The dosage of the compounds of formula I can vary within wide limits depending on the pathogenic fungi to be controlled, the age and the individual condition of the patient and the mode of administration, and will, of course, be fitted to the individual requirements in each particular case. For adult patients a daily dosage of about 0.01 g to about 4 g, especially about 0.05 g to about 2 g, comes into consideration for the prevention and control of topical and systemic infections by pathogenic fungi. For cholesterol lowering the daily dosage conveniently amounts to between 1 and 1200 mg, preferably 5 to 100 mg, for adult patients. Depending on the dosage it is convenient to administer the daily dosage in several dosage units.
The pharmaceutical preparations conveniently contain about 1-500 mg, preferably 2-200 mg, of a compound of formula I.
The following Examples illustrate the present invention in more detail. They are, however, not intended to limit its scope in any manner. All temperatures are given in degrees Celsius.
