It ' is generally considered that in allergic asthma and other atopic diseases of human or anaphylactic shock in animals, various chemical mediators are released from the lung and other tissues and cause difficulties in the living body, such as contraction of smooth muscles, e.g., bronchi, pulmonary artery, etc., and enhancement of vascular permeabi¬ lity in the skin. As such chemical mediators, there are histamine and SRS-A. Hista ine plays an important role in guinea pig anaphylactic shock but no in allergic asthma in human [Eiser, Pharmacol. Ther., ?, 239-250 (1982)]; whereas a number of evidences suggest that SRS-A is the most important chemical mediator of allergic asthma in human [Brocklehurst, J. Physiol., 151, 416-435 (1960); Austen and Orange, Am. Rev. Resp. Dis., 112, 423-436 (1975); Adams and Lichtenstein , J. Immunol., 122, 555-562 (1979)]. The development of medicaments for prophylaxis, elimination and alleviation of hypersensitive reactions was performed, aiming at inhibiting the production and release of such chemical mediators or antagonizing the action of these chemical mediators. As an inhibitor of histamine release, disodium cromoglycate is well known and as an inhibitor of actions induced by histamine, various anti-histaminics are commercially available. On the other hand, SRS-A i.^ known as a slow reactive and long acting chemical mediator while histamine ' is" a rapid acting and short -acting chemical mediator. It has recently been clarified that SRS-A is a mixture of Leukotrienes C . , D . and E 4 , the structure of which have been determined by Samuelsson. SRS-A, namely, Leukotri- enes are metabolites of polyvalent unsaturated fatty acids (in particular, arachidonic acid) with lipoxygenase and it has been reported that SRS-A has various activities such as acceleration of mucus secretion, reduction of mucociliary movement, coronary artery contraction, reduction of cardiac contraction, etc., in addition to the aforesaid action as chemical mediator in immediate hypersensitivity reactions. Accordingly, it has been desired to develop medicaments capable of inhibiting the production and release of SRS-A or antagonizing the. effects of SRS-A. The present inventors have extensively investigated medicaments capable of inhibiting the production and release of SRS-A or medicaments capable of antagonizing the effects of SRS-A. As a result, they have found that the compounds (I) of the present invention strongly antagonize SRS-A and have accomplished the present invention. (Effects of the invention) The compounds (I) of the present invention are useful as prophylaxis and treatment for various allergic diseases (for example, bronchial asthma, allergic rhinitis, urticaria) or, ischemic heart diseases, inflammation, etc. induced by SRS-A since the compounds strongly antagonize SRS-A as described above. Further some of the compounds of the present invention exhibit an activity similar to that of SRS-A. It can be expected that such compounds having the SRS-A agonist activity can be used in treatment for intestinal tube ~ 5 paralysis and also effective as reagents for investigations of anti-SRS-A agents or SRS-A antagonists, in place of Leukotrienes that have been heretofore difficult to acquire in a stable form. The compounds (I) of the present invention can be 10 orally or perenterally administered safely as medical compositions [for example, tablets, capsules, powders, granules, pills, ointments, syrups, injections, inhalation, sapositories] as they are, or by mixing with known pharma¬ ceutically acceptable carries, excipients, etc. Dose may 15 vary depending upon object to be administered, route for administration, condition, etc. but daily dose is generally 0.1 to 500 mg, preferably 1 to 200 mg, for adult. The dose is orally or perenterally administered twice or three times a day. 20 (Processes) The compounds of the present invention '"-an be prepared, * for example, by processes shown by the following reaction equations: 5 Process 1 Xa-D or reactive derivative thereof Process 2: or reactive derivative thereof Process 3: (Ie) Process 4 Process 5: Process 6: or its salt Process 7: Process 8: Process 9 wherein A, n, R, , X, , -(B)—, X_, Y, and D have the same significances as described hereinabove and other symbols represents the following significances: M, : a hydrogen atom or an alkali metal atom when Y, is an oxygen atom or- a sulfur atom and when Y, is an i ino group, a hydrogen atom; %-_ '- a halogen atom or a sulfonyloxy group; Y, : a methylene group or a methylenecarbonyl group (-CH 2 C0-) ; Y : a methylene group or a carbonylmeth lene group 6 (-COCH 2 -); Z- : a halogen atom; R fi : a phenyl group or a butyl group; R_: a lower alkyl group or a lower alkoxyphenyl-lower alkyl group; Y_: an oxygen atom or a sulfur atom; M_: a hydrogen atom or an alkali metal atom.

Further conversion of one product into another product can be performed in a conventional manner. For example, a compound wherein R- is: / R 4 -N< R_ wherein R. and R_ both are not a hydrogen atom, can be obtained by alkylation, acylation, etc. of a compound wherein R_ is an amino group; a compound wherein R~ is a halo-lower alkyl group by halogenation of a compound wherein R. is a . hydroxy-lower alkyl-group; a compound wherein R_ is a hydroxymethyl group by reduction of a- compound wherein R^ is a formyl group; a compound wherein R_ is a lower alkox - lower alkyl group by lower alkoxylation of a compound wherein R- is a halo-lower alkyl group; a compound wherein R 2 is a lower alkoxycarbonyl-lower-^alkylthio-lower alkyl group by lower alkoxycarbonyl-lower alkylsu-lfenylation of a compound wherein R 2 is a halo ' -lower- alkyl group. These conversion- modes are described in the examples later in detail. The compounds of the present invention produced by these various processes can be isolated and purified by applying thereto chemical procedures generally used in the art such as extraction, recrsytallization, column chromato- graphy, etc. (1) Inhibition of SRS-A- and LTD.-induced contractions of guinea-pig ileum and trachea Method: Male Hartley quinea-pigs, weighing 500 to 700 g were sacrificed by a blow on the head. The ileum and tracheal strips prepared according to the method of Constan- tine (1965) were suspended with 1.0 g tention in an organ bath containing 10 ml of Tyrode solution equilibrated with a mixture of 95% 0 2 and 5% C0 2 at 37°C.
