In this regard, the reaction can be carried out by protecting the substituting groups with in each case protective groups, however, the sequence of removing the protection is not so significant.

The method of Synthesis 1:

The compound (3) obtained by condensation of compound (1) with compound (2) in the presence of a base. Next, the protective group for the hydroxyl group of the thus obtained compound (3) is removed by formation of compound (4). Its terminal olefinic group in turn diol by the action of an oxidizing agent, such as N-methylmorpholin-N-oxide, in the presence of a catalyst of osmium tetroxide, and then subjected to oxidative cleavage by the action of periodate sodium or similar reagent with the formation of the aldehyde.

In addition, the treatment according to the invention can be used in the treatment of cancer based on its antitumor actions, and examples of interest for treatment include various types of cancer, such as lung cancer, gastrointestinal cancer, ovarian cancer, uterine cancer, breast cancer, liver cancer, head and neck cancer, blood cancer, kidney cancer and tumors of the testicles.

The compound of the present invention may be injected through a variety of injections, such as intravenous injection, intramuscular injection and subcutaneous injection, or by using various methods, such as oral or subcutaneous administration. Oral administration among these methods is desirable from the viewpoint of the effect, which is able described below. In the case of oral administration can be used any of the free compounds or salts.

When conducting a test using non-cancerous mice compound according to this invention showed no renal toxicity.

The applicability of the compounds according to the invention in the form of oral drugs can be predicted on the basis of tests in vitro using liver microsomes of human rights. In the case of oral administration the drug is dissolved in the gastrointestinal tract and undergoes metabolism in the digestive tract and liver and then enters the circulatory system. Accordingly, it is believed that the metabolism of drugs in the liver shows the effect on the expression efficiency of the medicines. In particular, predicted that the connection according to the invention and similar compounds undergo metabolism under the influence CYP3A, which is the enzyme distributed in microsome liver. Thus, the prediction of metabolism in tests in vitro using liver microsomes is important when considering the possible clinical application in practice. It was reported, for example, in Pharm. Tech. Japan, 13, 17-39, 1997, J. Pharmacol. Exp. Ther., 283, 46-58, 1997 that the predicted values of metabolism during in vitro testing using liver microsomes practically coincide with the values measured in clinical tests on humans. M is croome liver of man comes, for example, the company Xenotech LLC, and the measurement of metabolic rate may be based on the above log.

After measuring metabolic rate in microsome liver is possible to calculate the bioavailability of drugs as theoretical value (J. Pharmacol. Exp. Ther., 283, 46-58, 1997). Bioavailability is defined as the number and level of drug that reaches the circulatory system in relation to the number of entered drug (Pharmacokinetic Studies on Drug Development, edited by Yuichi Sugiyama, p.15, published by Yakuji Jino). In the case of oral administration, there are many obstacles to getting drugs into the blood circulation system, such as dissolution in the gastrointestinal tract, passing through the mucous membrane of the intestinal tract and metabolism in the intestinal tract and liver. Thus, it is considered that the range of changes in its final concentration in the blood, namely, the bioavailability, the individual becomes higher in comparison with the case of direct injection into the bloodstream. Hellriegel and others examined the extent of bioavailability and its individual changes (CV value) for 149 names of the various drugs available on the market, and said that between them there is a negative correlation (Clin. Pharmacol. Ther., 60, 601-607, 1996). Thus, it is known that the range of variability in bioavailability among individuals becomes larger at that time which I value bioavailability becomes smaller.

With regard to anticancer agents, they are administered in amounts almost close to the maximum tolerated dose, in order to enhance the reaction, so that therapeutic range and the range of toxicity become very close, this results in a narrowing of the safe range. Thus, it becomes difficult to use as an antitumor agent with a drug with a wide range of individual variability of bioavailability.

As for the compounds of the present invention, the rate of its metabolism in microsomes human liver was reduced, and theoretical value bioavailability of its unmodified form is also increased. Thus, it was predicted that the range of variability of the values of bioavailability of unchanged compounds for individuals will be small. Because of this effect it is possible to conduct oral administration of the compounds according to the invention from the point of view of safety in a larger range of security, as well as from the point of view of increasing the effectiveness of the medication. In this regard, theoretical value bioavailability of unchanged compounds preferably equal to 0.4 or higher, more preferably 0.7 or higher.

In addition, the applicability of the compounds according to the invention as preparations for oral call is to be placed can be predicted on the basis of a test bioavailability (BP) in monkeys. The metabolism of the compound (V) by liver microsomes of mouse and dog is slow, and the property of its oral absorption is really great. On the other hand, its metabolism under the action of liver microsomes monkey is fast, as in the case of microsomes human liver. In this case, the property of the oral absorption of the compound (C) for monkeys is low. On the other hand, the metabolism of compounds according to the invention under the action of liver microsomes monkey is slow as in the case of liver microsomes of mouse and dog. Thus, when the bioavailability (BP) was measured using monkeys to get confirmation improve absorption by oral administration via inhibition of the metabolism, it was confirmed that the oral absorption in monkeys was significantly superior to the compounds according to the invention compared with the data for the connection (In).

As for the method of producing the pharmaceutical composition of drugs and anticancer drugs, they can be obtained by selection of an appropriate pharmaceutical preparation based on the desired method of maintaining and using the commonly used methods of obtaining. Examples of dosage forms of the antitumor agent according to this invention for oral administration may include tablets, p. the Rosca, granules and capsules. Examples of other dosage forms include solutions, syrups, elixirs, and aqueous or oil suspensions. Desirable of the above are capsules, tablets and solutions. In the case of injection in the retrieval process can be used additives, such as stabilizers, antiseptic agents, and agents that promote solubilization. If the solution containing the mentioned auxiliary substances is transformed into a solid preparative form freeze-drying or other similar way, it can be used as a pharmaceutical product, which is dissolved before use.

Solutions, suspensions and emulsions can be represented as liquid preparations and process for their preparation may be additional agents, such as suspendresume agents and emulsifiers.

The connection according to this invention can be used for the treatment of cancer in mammals, especially humans, and in the case of the introduction of man it is advisable to enter it once a day and repeat at appropriate intervals.

With regard to dose, it is desirable to introduce the drug in the range from about 0.5 mg to 50 mg, preferably from about 1 mg to 20 mg, but 1 m²the surface area of the body.

The invention is described in detail in the following examples. In the description of examples will be used following the e reduction. The first denotes tert.-butoxycarbonyl group. AC represents acetyl group, Bz represents benzoyloxy group, and TIPS means triisopropylsilyl group.

The platelet count was expressed as platelets in the group with the entered connection/platelets in the group with the solvent) } × 100

Renal toxicity was defined as "modified" in that case, when the anatomy watched this macroscopic change as wilting, or such a change, as the deposition of transparent droplets of the substance in the cytoplasm of the ochechnogo cylindrical cells on histological examination.

SAMPLE TEST 2

B16 Melanoma BL6 subcutaneously transplanted mice (C57BL/6), and after 4 days was administered to each of the connections. In the case of intravenous administration, the compound of the formula And was introduced after its dissolution in a solvent mixture of ethanol, tween 80 and 5% glucose (5:15:80 (vol./vol.), the compound of Example 7 after dilution of the mixture is the same solvent at a ratio of 5:5:90 (vol./vol.). In the case of oral administration, each of the compounds suspended in 0.5% aqueous solution of sodium salt of carboxymethyl cellulose. Every 2 or 3 days after injection was measured body weight, every animal operated on 15 days after transplantation for measuring the weight of the tumor. The antitumor effect was calculated by the following formula: {1-(weight of tumors in the group with the compound/weight of the tumor in the group with the solvent)} × 100

Each group contained six mice.

EXAMPLE TEST 3

METABOLISM IN MICROSOME P450 PERSON

Each of the test samples RA is tarali in a mixture of Aceto-nitrile/water (1:1 vol./about.) up to a concentration of 500 μm, and the solution was mixed with microsomes human liver (Xenotech LLC) and other components such as various coenzymes and buffer solutions, and allowed to undergo reaction metabolism at 37° C.

The reaction solution consisted of phosphate buffer (0,076 M; final concentration, the same will apply hereinafter), the test sample (10 μm), microsome human liver (1 mg/ml), glucose-6-phosphate (10 mm), glucose-6-phosphate dehydrogenase (1 unit/ml), magnesium chloride (4 mm) and recovered phosphate nicotinamide adenine dinucleotide (β -NADP, 1 mm), and 500 μl of solution was used in one reaction. In this case the reaction solution, except β -NADP, pre-incubated at 37° With 2 minutes, then the reaction was initiated by addition of an aqueous solution β -NADP (50 mm, 10 ál).

The reaction was stopped by adding 1 ml of ice-cold acetonitrile in 1, 2 or 5 minutes after the start of the reaction.

In this regard, the sample 0 minutes after start of the reaction was obtained by adding water instead of the aqueous solution β -NADP and immediately add 1 ml of acetonitrile. To each of these samples was added 100 μl of substance - internal standard, and the reaction solution was centrifuged for 15 minutes. The obtained supernatant was injected into a column for high performance liquid chromatography (HPLC) to measure the desired concentration of Varazze. The number decreased compared to the concentration at 0 minutes from the start of the reaction was taken as the resulting number of metabolites (nmol/mg protein). The amount of metabolite formed per 1 minute (constant speed metabolism: k (nmol/min/mg protein)) was calculated as the slope of a plot of the linear dependence of the amount of metabolite formed from the reaction time, calculated by the method of least squares.

From the thus obtained rate constants k metabolism (nmol/min/mg protein) was calculated for specific hepatic clearance (CLint) according to the following formula. CLint (ml/min/kg body weight) = k × (g liver)/(kg body weight) × (45 mg protein microsome assay)/(g liver), liver weight per 1 kg of body weight is 20 g

In addition, it was calculated the liver clearance (CLh) of values Clint in accordance with the model of ideal mixing (J. Pharmacol. Exp. Ther., 283, 46-58, 1997).

CLh (ml/min/kg body weight) = Q × Clint/(Q + Clint), where Q is the blood flow through the liver of a person, defined as 20 ml/min/kg

theoretical value bioavailability (F) was calculated from CLh according to the following formula: F = (1-CLh/Q).

In addition, theoretical value of the bioavailability of unchanged compound was calculated by the formula 1 - F.

The results are presented in drawing 1 and Table 1. Theoretical values of F unchanged form compounds according to the invention exceeded theoretical value of F 0,27 unmodified form of the control connection (the connection formulas), which means that the range of variation of bioavailability decreases, the separation of therapeutic range, and range of toxicity can be achieved more accurately and, therefore, possibly using oral administration.

EXAMPLE TEST 4

The compound of formula (V) or of Example 1 was injected monkey intravenously or orally as a single dose and measured the changes in its concentration in blood for calculating PPK_o-∞. ACC_o-∞mean area under the curve of concentration of drug in the blood in vremena period from the time of injection (0 h) to infinity, and it can be calculated in accordance with the method (rule of-line)described in Kiyoshi Yamaoka and Yusuke Tanigawara, Yakubutsu Sokudoron Nyumon (Pharmacokinetics), pages 116-117, moreover, the ratio of CPD oral introduction to CPD intravenously was calculated as oral VA. Test for compounds of formula (I) was carried out on different individuals of the same monkeys by intravenous or oral administration, as well as test for compounds of Example 7 was carried out on 4 monkeys of the same species with intravenous and oral administration to calculate the average value of CPD.

Animal: the female of Massa computer, the method of administration (compound of formula (In)) [intravenous] ethanol: tween 80: 5% glucose = 5:5:90, [oral] 0,1 N solution of Hcl, (compound of Example 7) [intravenous] 10% β -CyD-SBE7 (pH 3.5 in physiological solution), [oral] 40 mm acetate buffer (pH 4,0).

INDUSTRIAL APPLICABILITY

The connection according to the invention was superior in terms of its toxicity and showed no renal toxicity. The connection according to the invention showed high antitumor efficacy in mice when administered orally. Because the connection according to the invention has a high theoretical value of F for its unmodified form, the range of changes in bioavailability is reduced, and can be achieved separation therapeutic range and range of toxicity. The connection according to the invention showed excellent properties of absorption when administered orally to monkeys. Accordingly, the connection according to the invention can be used as an antitumor agent that can be administered orally.
