~I.r~ 51.2~
The present Inventlon relates to 9-halogen prostaglan-dln derlvatlves, processes for thelr manufacture as well as thelr use as pharmaceutlcals.

From the extens/ve state of the art as regards prostaglandlns and thelr analogous substances It Is known that thls class of substance Is sultable for the treatment of mammals, man Included, because of thelr blologlcal and pharmacologlcal propert/es. However, the/r use as pharmaceutlcals often meets 10 wlth dlfflcultles. The effectlve duratlon of most natural prostaglandlns Is too short for therapeutlc purposes slnce they are rapldly metabollzed by varlous enzymatlc processes. All the structural changes have the alm of Increaslng the effect ~e dura-tlon as We// as the selectlvlty of the effect.

It was now found that 9-halogen prostaglandln derlva-tlves have outstandlng effectlve speclflclty, better effectlve-ness, longer effectlve duratlon than natural prostaglandlns and thelr derlvatlves and are especlally sultable for oral applIcatlon.

After comple-tlon of the reactlon In 1 to 30 mlnutes the solvent Is removed and the ster purlfled In the customary fashlon. Dlazoalkanes are elther known or can be manufactured by the known methods ~Org.
Reactlons, Vol. 8, pp 389-394 (1954)].
~0 The ester group -C~OR for R1, In whlch fl2 represents a substltuted or unsubstltuted aryl group, Is Introduced by the methods famlllar to the expert.

For example, the 1-carboxy compounds reacted wlth the correspondlng arylhydroxy compounds wlth dlcyclohexyl carbodl-lmlde In the presence of a sultable base, e.g. pyrldlne, DMAP and trlethylamlne, In an Inert solvent. Posslble solvents are methy-/ene ch/or/de, ethy/ene chlorIde, chloroform, acet/c ether and tetrahydrofuran, preferably chloroform. The react/on takes p/ace at temperatures of -30C to +50C. Preferably at 10C.

The prostaglandln derlvatlves In accordance wlth for-mula I wlth R2 In the meanlng of a hydrogen atom can be converted Into a salt wlth sultable amounts of the correspond/ng Inorganlc base together wlth neutrallzatlon. For examp/e, when the corre-spondlng PG aclds are dlssolved In water whtch contalns the stol-ch/ometr/c amount of base, the solld, Inorganlc salt Is obtalned after evaporatlon of the water or after the addltlon of a solvent that can be mlxed wlth water, e.g. alcohol or acetone.

\

For the manufacture of an amlne salt, whlch Is done In the customary fashlon, the PG acld Is, for example, dlssolved In a sultable solvent, e,g. ethanol, acetone, dlethylether, acetonl-trlle or benzene, and at least the stolchlometrlc vo/ume of the amlne /s added to thls solutlon. In thls connectlon the salt Is usually obtalned In solld form or Isolated after evaporatlon of the solvent In the customary fashlon.
,~0 The amlde group -C--NHR3 for Rl Is Introduced by the methods famlllar to the expert. The carboxyllc aclds of formula I (P2=H) are flrst converted Into the mlxed anhydrlde In the presence of a tert/ary amlne, e.g. trlethylamlne, wlth chloro-formlc acld Isobutyl ester. The reactlon of the mlxed anhydr-lde wlth the alkall metal salt of the correspondlng amlde or wlth ammonla (~3=H) or the reactlon of the correspondlng amlne takes place In an Inert solvent or m/xture of solvents, _ 10 -i r~ ! ' ~;~5~

e.g. tetrahydrofuran, dimethoxyethene, dimethylformamide, hexamethylphosphoric acid triamide, at temperatures of between -30 C and +60 C, preferably at O C to 30 C.

Another way to introduce the amide group -C-NHR3 for R1 with R3 in the meaning of an acid radical is to make a 1-carboxylic acid of formula I (R2=H), in which the free hydroxy groups possibly have intermediate protection, react with compounds of formula III 5' O = C = N - R3 (III) where R3 has the meaning indicated above.

The reaction of the compound according to formula I (R2=H) with the isocyanate of formula III takes place after the possible addition of a tertiary amine, e.g. triethylamine or pyridine. The reaction can take place without solvents or in an inert solvent, preferably ace-tonitrile, tetrahydrofuran, acetone, dimethyl acetamide, methylene chloride, diethyl ether, toluene, at temperatures of between -80 C to 100 C, prefe-rably at O to 30 C.

If the primary product contains OH groups in the prostane radical, these OH groups are also made to react. If, in the end, final products are desired which contain free hydroxyl groups in the prostane radical, it is advisable to start with primary products in which intermediary protection is preferably provided by easy-to-separate ether or acyl radicals.

The compounds of formula II with a 9~ -hydroxy group that serve as primary products are either known or can be manufac-tured by the processes indicated in DE-OS 26 27 910.

The compunds of formula II with a 9B-hydroxy group are ob-tained from the 9~ -hydroxy compounds by way of an inversion reaction of the kind described in Synthesis, 292-294 (1980).

The analogue prostaglandin substances of formula I are valuable pharmaceuticals because they have a much improved (higher specificity) and above all a much longer effect, with a similar range of effects, than the corresponding natural prostaglandins.

The new analogue prostaglandin substances have a strongly luteolytic eEfect, i.e. much lower doses are needed to initiate luteolysis than with the corresponding natural prostaglandins.

To start abortions, especially after oral or intravaginal application, much lower doses of the new analogue prosta-glandin substances are needed in comparison to the natural prostaglandins.

In the recordings of isotonic uterus contraction in the anesthesized rat and in the isolated rat uterus it can be seen that the substances in accordance with the invention are much more effective and longer-lasting than natural prostaglandins.
After a single enteral or parenteral application the new prostaglandin derivatives are able to induce menstruation or interrupt pregnancy. Furthermore, they are suitable for synchronizing the sexual cycle of female mammals such as rabbits, cattle, horses, pigs, etc. Furthermore, the prostaglandin derivatives in accordance with the invention are suitable for dila-tion of the cervix prior to diagnostic or therapeutic intervention.

The good tissue-specificit~ of the antifertility substances in accordance with the invention can be seen in the investi-gation of other unstriated muscle organs, e.g. the ileum of guinea pigs or isolated rabbit trachea where much less stimu-lation is to be observed than with the natural prostaglandins.
The substances in accordance with the invention also have a bronchospasmolytic effect. Moreover, they reduce the swelling of nasal mucous membrane.

The active insredients in accordance with the invention in~
hibit the secretion of gastric acid, display a cytoprotective and an ulcer-healing effect, and thereby counter the undesir-able consequences of non-steroidal antiphlogistic substances (prostaglandin synthesis inhibitors). They also have a cytoprotective effec-t on the liver, kidneys and pancreas.

Some of the compounds have the effect of reducing blood pressure, regulating cardiac rhythm disorders and inhibiting platelet aggregation, with the possible uses resulting therefrom. The new prostaglandins can also be used in combi-nation, e.g. with B-blockers, diuretics, phosphodiesterase inhibitors, calcium antagonists and antigestagens.

The dosage of the compounds is 1 to 1500 ~g/kg/day when administered to human patients.

For medical usage the active ingredients can be converted into a su:itable form for inhalation, oral, parenteral or local (e.g. vaginal) application. For inhalation it is advisable to produce aerosol solutions.

For oral application, for e~ample, tablets, dragees or capsules are suitable.

Sterile, injectable, aqueous or oily solutions are used for parenteral application.

5~2~L

Suppositories, for example, are sui-ta~le for vaginal appli-cation.

Thus the invention also relates to pharmaceuticals on the basis of the compounds of formula I and customary adjuvants and carrier su~stances, c~clodextrinclathrates included.

In conjunction with the adjuvants known and customary in galenicals the active ingredients in accordance with the invention are supposed to serve, for example, for the manu~
facture of preparations for initiation of an a~ortion, for control of the cycle, for initiation of birth, for treat-ment of hypertonia or for the treatment of gastrointestinal disorders, e.g. for healing gastric and duodenal ulcers.
The preparations can contain 0.01 to 100 mg of the active compound for this purpose as well as the other applications~

The following examples are supposed to explain the invention in more detail, without setting any limits.
