INDOLE DERIVATIVES AND MEDICINAL USE THEREOF

Abstract: The present invention relates to indole derivatives represented by the following compound 1 and the pharmacologically acceptable acid addition salt thereof. The compounds of the present invention were found to exhibit strong antitussive and analgesic actions as a result of pharmacological evaluation, and can be used in the pharmaceutical field as effective antitussives and analgesics.

Description: Technical Field The present invention relates to novel indole derivatives and medical applications thereof. Background Art Nowadays, opioid receptors are classified into three types, µ, δ, and κ. Among these, δ opioid receptors have been researched only for a short time, and ligands selective to this receptor, especially alkaloid agonists have not yet been found and developed. Accordingly, δ opioid receptors have been lacking in research as compared with the other opioid receptors. Recently, among pharmacological actions relating to δ opioid receptors, antitussive action and analgesic action are attracting attentions. Codeine, which is known as a typical antitussive capable of surely stopping coughing, acts on µ opioid receptors while essentially causing severe side effects such as drug dependence, respiratory depression, constipation, and suppression of CNS. There is, therefore, a demand for highly active antitussives which are free from µ opioidergic side effects as shown in codeine, and can be safely used. In recent years, although some κ opioid agonists were reported as showing antitussive activity, removal of aversion and psychotomimetic could not be achieved in many cases. Additionally, due to their agonistic properties on the opioid receptors, removal of suppression of CNS is still a problem to be solved. Lately, although some δ opioid antagonists were also reported as showing antitussive activity, they required improvement in antitussive activity for practical use. Meanwhile, µ opioid agonists represented by morphine have been used as analgesics. The use of such agonists is, however, allowed only under strict management in view of the above-mentioned side effects. Further, in κ agonists, the above-mentioned side effects, i.e. aversion and psychotomimetic are also problems to be solved. Moreover, no alkaloid δ agonist has yet been developed, and its potential as an analgesic has not yet been clarified. Disclosure of Invention Accordingly, the object of the present invention is to provide δ opioid ligands (agonists and antagonists) which have a novel chemical structure, can be used as antitussives and analgesics, and are free from the above-described severe side effects such as drug dependence, respiratory depression, constipation, and suppression of CNS. The Inventors earnestly conducted research to obtain the above-mentioned ideal δ ligands, and found that indole derivatives represented by the following general formula (I) and pharmacologically acceptable acid addition salts thereof exhibit strong antitussive or analgesic activities as δ ligands.

Practically, the compounds of the present invention represented by the general formula (I) can be obtained according to the process shown in Chart 1 below. Specifically, a morphinan derivative represented by the above general formula (II) (in the formula, definitions of R 1 , R 2 , R 3 , R 9 , R 10 , and R 11 are the same as the aforementioned definitions) is reacted with a hydrazine derivative represented by the above general formula (III) (in the formula, definitions of-X-, m, n, R 4 , and R 5 are the same as the aforementioned definitions) in a solvent in the presence of an acid catalyst. Examples of solvents which can be used herein include alcoholic solvents such as methanol, ethanol,1-propanol, and 2-propanol; aprotic dipolar solvents such as DMF and DMSO; aromatic hydrocarbon solvents such as benzene, toluene, and xylene; ether solvents such as diethyl ether, THF, and DME; halogeno carbon solvents such as dichloroethane, chloroform, carbon tetrachloride, and 1,2-dichloroethane; and organic acids capable of being used as solvents such as acetic acid and propionic acid. Among these solvents, preferred are alcoholic solvents such as methanol, ethanol,1-propanol, and 2-propanol; aprotic dipolar solvents such as DMF and DMSO; and organic acids capable of being used as solvents such as acetic acid and propionic acid. In particular, methanol, ethanol, DMF, and acetic acid are especially preferred. Examples of the acid catalyst which can be used in the present invention include inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, hydrobromic acid, and hydroiodic acid; sulfonic acids such as methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p -toluenesulfonic acid, and camphcrsulfonic acid; carboxylic acids such as acetic acid, lactic acid, citric acid, oxalic acid, glutaric acid, malic acid, tartaric acid, fumaric acid, mandelic acid, maleic acid, benzoic acid, and phthalic acid (incidentally, although the reaction may not smoothly progress with calboxylic acid alone, a strong acid may optionally be added as a cocatalyst in such a case); and acidic ion-exchange resin. Among these acid catalysts, hydrochloric acid, sulfuric acid, methanesulfonic acid, p-toluenesulfonic acid, and acidic ion-exchange resin are preferably used. Further, the amount of the acid catalyst to be added is 1 to 30 equivalent amounts, and preferably,1 to 10 equivalent amounts relative to the total amount of base present in the reaction system. The acid catalyst may be added after converting the base component into salt, or may be added into the reaction mixture in a desired amount. The reaction temperature is 0 to 300°C, preferably 25 to 170°C, and more preferably 60 to 120°C. As a result of pharmacological evaluations in vitro and in vivo, the compounds of the present invention expressed by the general formula (I) were found to be compounds which act on δ opioid receptors and have a strong antitussive and analgesic activity, as shown with practical examples described below. Accordingly, the compounds of the present invention are expected to serve as effective antitussives and analgesics. Actually, in the pharmaceutical field, they are useful as remedies for various respiratory diseases such as cold syndrome, acute bronchitis, chronic bronchitis, bronchiectasis, pneumonia, silicosis and silicotuberculosis, lung cancer, upper respiratory inflammation (such as pharyngitis, laryngitis and gravedo), asthmatic bronchitis, bronchial asthma, infantile asthma, (chronic) pulmonary emphysema, pneumoconiosis, pulmonary fibrosis, pneumosilicosis, lung abscess, pleurisy, tonsillitis, cough urticaria, and whooping cough; as cough inhibitors such as for bronchography and bronchial examinations; and as analgesics such as against postoperative pain, cancer pain, and other ordinary pain. On clinical application of the antitussive/analgesic agent according to the present invention, the compound may be a free base or a salt thereof, or may be used in combination with suitable excipients such as stabilizers, buffers, diluents, isotonizing agents, and antiseptics. Further, the antitussive/analgesic agent of the present invention may be orally administered in the form of a tablet, a capsule, a granule, a powder, or a syrup; may be parenterally administered in the form of an injection solution, a suppository, or a liquid; or may be locally administered in the form of an ointment, a cream, or a stupe. Preferably, the antitussive/analgesic agent of the present invention contains 0.00001 to 90% by weight of the above-described active principle, and more preferably, 0.0001 to 70% by weight. The dosage is optionally determined according to the disease condition, age and body weight of the patient, and the administration method. For an adult, in terms of the active principle, the dosage for injection is 0.1 µg to 1 g per day, and the dosage for oral administration is 1 µg to 10 g. In each case, either single administration or multiple administration can be employed. Examples The present invention will be further illustrated in detail with reference to the following examples to which the present invention is not limited. [EXAMPLE 1] 17-Cyclopropylmethyl-6,7-didehydro-4,5α-epoxy-3,14β-dihydroxy-1',7'-ethylene-6,7,2',3'-indolomorphinan 1 Hydrochloride Naltolexone hydrochloride (383 mg), N-aminoindoline 1a methanesulfonate (375 mg, 1.1 equivalent amounts), and methanesulfonic acid (0.14 ml, 2 equivalent amounts) were mixed in ethanol (8 ml), and refluxed for 8.5 hours. After being allowed to cool, the resultant was poured into a 5% sodium hydroxide solution (20 ml), subjected to extraction with chloroform (20 ml x 3), dried over anhydrous magnesium sulfate, and concentrated.

[EXAMPLE 67] δ-Opioid Activity Using mouse vas deferens (MVD), antagonistic compounds were examined for antagonism against a δ-opioid agonist DPDPE, and agonistic compounds were examined for inhibitory activity against MVD contraction by electric stimulation, and for antagonism by a δ-opioid antagonist NTI. Male ddy strain mice were used in this experiment. Each of the vas deferens isolated from the mice was hung in a Magnus tube which was filled with a 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), and aerated with a gas of 5% carbon dioxide and 95% oxygen and maintained at 37°C. Electric stimulation was applied through upper and lower ring-shaped platinum electrodes at 0.1 Hz and 5.0 mS. Tissue contraction was recorded on a polygraph using an isometric transducer. <Antagonist> Initially, DPDPE was added in a cumulative manner to determine the IC 50 value (concentration for 50% inhibition of contraction induced by electric stimulation). Next,100 nM of a sample compound was added to the system beforehand, and 20 minutes later, DPDPE was added in a cumulative manner. According to the above procedure, the ratio of the IC 50 value of DPDPE in the presence of the sample compound to that in the absence of it was determined, and the pA 2 value was calculated in accordance with the Schild, et al.'s method [Schild, H.

Capsaicin was fed for inhalation at a rate of 70 times/min. and 10 ml each time. <Experimental Schedule> Two hundred and seventy minutes before the drug administration, capsaicin was inhaled for 5 minutes, and inducement of coughing was confirmed during this period. Thirty minutes after the drug administration, capsaicin was inhaled for 5 minutes, and the number of induced coughs during capsaicin inhalation was counted. Antitussive effect was evaluated by determining an inhibitory ratio, namely, the ratio of the number of coughs after the drug administration to that before the drug administration. Capsaicin was dissolved in saline. Each drug was dissolved in a 10% DMSO solution and intraperitoneally administered. The effect of the drug is expressed with an ED 50 value which is the dosage for 50% cough inhibition.
