Description: TECHNICAL FIELD The present invention relates to compounds having affinities to δ-opioid receptor. δ-opioid receptor relates to analgetic, immune and circulatory systems (especially blood pressure) and ligands having high selectivities to this receptor can be used as analgesics, immunosuppressive agents (employed in organ transplantation (kidney, liver and heart), skin transplantation, treatment of autoimmune diseases (rheumatism, various allergies and collagen diseases) and the like], immunopotentiating agents (anti-tumor agents and anti-virus agents), blood pressure-lowering agents and the like. PRIOR ART Opioid receptors include three types called µ, δ and κ. Among these, δ-opioid receptor relates various pharmacological effects as mentioned above. However, the number of agonists and antagonists having high selectivities to this receptor is small and the mechanism has not yet been clarified. Recently, a non-peptidic antagonist NTI was discovered by Portoghese (Portoghese, P.S. et al., J. Med. Chem., 31, 281 (1988); 33, 1714 (1990)). Subsequently, synthesis of an antagonist (5'-NTII) which can irreversibly bind to the receptor was reported (Portoghese, P.S. et al., J. Med. Chem. 33, 1547 (1990)). Since a ligand which irreversibly binds to the receptor is very useful in studying the receptor, researchers are paying more and more attention to 5'-NTII. However, its antagonist activity and selectivity to δ-opioid receptor are low. Therefore, as a probe for studying the receptor, a ligand having higher activity and selectivity is demanded. On the other hand, participation of endogenous opioid peptides such as enkephalin, and morphine in immune system has been pointed out and it is known that opioids may possibly be immunopotentiating agents and immunosuppressive agents. Paying attention to this, the present inventors studied influence on immune system by NTI. As a result, it was shown that this compound exhibits immunosuppressive action in vitro and in vivo (Japanese Laid-open Patent Application (Kokai) No. 3-223288). Since currently used immunosuppressive agents have problems in toxicities and side effects, an agent having a low toxicity or having a different mechanism of action is demanded. It is expected that δ-opioid antagonist is one of the candidates thereof. It has recently been discovered that opioids relate to flow of calcium ion into cells, which has a relationship with ischemia in brain, and that opioids have brain cell-protecting action. Thus, use of opioids as a brain cell-protecting agent is more and more expected. DISCLOSURE OF THE INVENTION An object of the present invention is to provide a δ-opioid antagonist having high antagonist activity and receptor selectivity. Another object of the present invention is to provide a δ-opioid antagonist having high immunosuppressive action and brain cell-protecting action.

As the organic solvent, halogen-substituted solvents such as chloroform and methylene chloride are preferred, and as the aqueous solvent, aqueous sodium hydrogen carbonate solution, aqueous potassium carbonate solution, aqueous sodium hydroxide solution, and aqueous potassium hydroxide solution are preferred. Mixed solvent of chloroform - aqueous sodium hydrogen carbonate solution is especially preferred, although the solvent is not restricted thereto. The reaction may be carried out at 0 - 150°C and satisfactory results are usually obtained at 50 - 100°C. The second step is the step for hydrolyzing the ester under basic condition. As the base, sodium hydroxide, potassium hydroxide or the like may be employed. As the solvent, mixed solvents between an ether solvent such as dioxane or THF and water are preferably employed. The reaction may be carried out at 0 - 150°C, and satisfactory results are obtained at 50 - 100°C. The third step is the step for condensing the carboxylic acid with amine to form amide. As the condensing agent, DCC, 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide hydrochloric acid salt and the like are employed. In view of the ease of post-treatment, 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide hydrochloric acid salt is preferred. As the solvent, halogen-substituted solvents such as chloroform, methylene chloride and 1,2-dichloroethane are preferred. The reaction may be carried out at 0 - 150°C, preferably at 20 - 80°C. The fourth step is the step for removing the protective group of hydrazine under acidic condition. As the acid, hydrochloric acid, sulfuric acid, nitric acid and the like may be employed, and hydrochloric acid is preferred. As the solvent, alcoholic solvents such as ethanol and methanol, ether solvents such as THF and dioxane, and ethyl acetate and the like are preferred, and satisfactory results are usually obtained by using ethyl acetate. The reaction may be carried out at -20 - 100°C, preferably at 0 - 30°C.

The pharmacological effects of the compounds according to the present invention will now be described. Example 17 <δ-opioid antagonist activity> Using mouse vas deferens (MVD), the antagonist activity against DPDPE which is a δ-opioid agonist was checked. Experimental Method In this experiment, ddy male mice were used. In a Magnus' tube which is filled with Krebes-Henseleit solution (NaCl 118 nM; KCl 4.7 mM; CaCl 2 2.5 mM; KH 2 PO 4 1.1 mM; NaHCO 3 25 mM; glucose 11 mM) kept at 37°C, and into which an atmosphere consisting of 5% carbon dioxide and 95% oxygen was flown, vas deferens taken from the animals was suspended. Electric stimulation was applied through ring-shaped platinum electrodes mounted on the upper and lower portions of the tube at a frequency of 0.1 Hz and 5.0 mS duration. The contraction of the tissue was recorded on polygraph using isometric transducer. First, DPDPE which is a δ-agonist was cumulatively added and IC 50 value (the concentration at which the contraction by the electric stimulation is inhibited by 50%) was calculated. Then 100 nM of the test compound was added. Twenty minutes later, DPDPE was begun to be added cumulatively. The ratio of IC 50 values in the presence and absence of the test compound, Ke value (the molar concentration of the test compound necessary for translating the dose-effect curve to the curve of twice dose) and pA 2 value were determined. The pA 2 value was determined by the method of Shild et al (Shild, H.O., Br. J. Pharmac. Chamotehr., 4, 277 (1949)). That is, the logarithm of the test compound (log[test compound]) was plotted along the abscissa and the logarithm of the value obtained by subtracting 1 from the ratio of IC 50 values was plotted in the presence and absence of the test compound [log(dose ratio - 1)] along the ordinate. The pA 2 value was determined from the value on the abscissa when the value on the ordinate of the obtained line is 0. Results The δ-antagonist activities of the principal compounds are shown in Tables 1 and 2. All of the compounds have high antagonist activities. In particular, compounds 77 , 119 and 190 exhibited activities as high as about 1.3 - 1.6 times that of NTI (Ke: 0.21, pA 2 : 9.68) which is the compound most widely used at present as a δ-antagonist. Example 18 <Change in δ-antagonist activity with time> Using MVD, the antagonist activities of compounds 173 and 174 against DPDPE were determined. The ratio of IC 50 values, Ke values and pA 2 values at 15 minutes, 30 minutes and 1 hour from the addition of the test compounds were calculated. The results are shown in Table 3 and Figs. 1 and 2. Since the concentrations of the test compounds are different, the reciprocals of Ke values were plotted in Figs. 1 and 2. While the activity of NTI did not change, the antagonist activities of compounds 173 and 174 and 5'-NTII increased with time. The increase in the activity is due to irreversible binding to the receptors. Although both compounds 173 and 174 are isomers of 5'-NTII, their activities were high. That is, compound 173 exhibited an activity at 1 hour of about 3.5 times that of NTI and about 170 times that of 5'-NTII, and compound 174 exhibited an activity at 1 hour of about 7 times that of 5'-NTII. Thus, although the activity of compound 173 is inferior to that of compound 174, the activities of these compounds are drastically higher than those of the conventional antagonists. As mentioned above, a large part of the various pharmacological actions of δ-opioid receptor has not yet been clarified. The compounds of the present invention have very high activities and selectivities, which irreversibly bind to δ-opioid receptor, so that they would be very useful in the future studies of opioids.

Experimental Method Hartley male guinea pigs were used. After killing the guinea pigs by clubbing, ilea were taken. The inside of the ilea was washed with a nutrient liquid and only longitudinal muscles were peeled off. Using the thus obtained longitudinal muscles, the tests were carried out using the same apparatus as used in the experiment employing MVD. First, U-50488H which is a κ-agonist was cumulatively added and IC 50 value was determined. Thereafter, the muscle was well washed with the nutrient liquid. After the contraction reaction became stable, 100 nM of a test compound was added. From 20 minutes after, U-50488H was cumulatively added and the ratio of IC 50 values, Ke value and pA 2 value were determined in the same manner as in the experiment employing MVD. Results Although most of the compounds did not exhibit agonist activities or antagonist activities, the five compounds shown in Table 4 exhibited strong κ-antagonist activities. These compounds also have δ-antagonist activities. A compound having both δ- and κ-antagonist activities are not known, so that it is expected that these compounds will be effective for clarifying unknown actions of opioids and relationships between δ-receptor and κ-receptor. κ-antagonist Activities of Indole Compounds Compound R 1 R 5 Ratio of IC 50 Values Ke(nM) pA 2 7 CPM 5'-CONH-CPM 22.8 4.59 8.34 9 CPM 5'-C 2 H 4 N(CH 3 ) 2 99.0 4.07 8.39 10 CPM 5'-CH 2 N(CH 3 ) 2 19.4 9.67 8.02 45 CPM 6'-SO 2 NH-CPM 3.22 45.1 7.35 47 CPM 6'-CONH-CPM 3.11 47.4 7.32 In the table, CPM means cyclopropylmethyl group. It is known that κ-opioid receptor relates to diuresis and protection of brain cells. The present inventors have already proved that nor-BNI widely known as κ-antagonist has brain cell-protecting action (Japanese Laid-open Patent Application (Kokai) No. 3-218313). Since the compounds of the invention are also κ-antagonists, it is expected that these compounds have the same actions. Thus, these compounds were tested for the brain cell-protecting actions.
