Description
~ 7 ~
The invention relates to new carbacyclin derivatives, processes for their manufacture and their use as pharmaceuticals.
In U.S. patent 4,~20,632 9-alkylated carbacyclin derivatives are described which possess ant:ithrombosis, antisecretion and bronchiodilatory properties. In addition they have thrombocyte aggregation inhibiting effect. It was found that by replacement of the methylene group in the 3-position of these carbacyclins by oxygen or by extension of the chain in the 9-position hiologically active derivatives are produced which are effective for a longer period of time, have greater selectlvity and possess better efficacy. Derivatives with extended chains in the s-pOsitiOn can be linked to polymeric carriers with only slight loss of biological activity. The compounds in accordance with the invention act in a bronchiodilatry manner and are suitable for inhibiting thrombocyte aggregation, for lowering blood pressure by a process of vasodilation and for :Lnhibiting gastric acid secretion.
The present invention thus provides carbacyclin derivatives with the general formula I:
~fll2~n~Rl ~.
Ii~2 C-~' ~ ~
~""s ~ 1, R g ~ A-W-D-E-R~
wherein n is 1 or 3 and Rl repressnts the group COOR2 where R2 is hydrogen or an alkyl with 1 to 4 C-atoms, Rg represents an alkyl group with 1 to 10 C-atoms or the group -C_C(CH2)m-R6 where m is a numbsr from 1 to 8 and R6 is hydrogen, hydroxy or amino, Y is hydrogen, A is a trans- -CH=CH- or .i ..
~ 3 -C_C-group, W is a hydroxymethylene group or ~H3 OH
group where the OH group is in the ~ - or ~ -position, D is a straight-chain saturated alkylene group with 1 to 5 C-a-toms or a branched chain saturated alkylene group with 2 to 5 C-atoms, E is a -C C group, R~ represents an alkyl group with 1 to 4 C-atoms, and R5 represents a hydroxy group and, when R2 represents a hydrogen atom, its salts with physiologically tolerable bases.
Compounds conforming to formula I repres~nt both (5E) and (5Z)-isomers.
Alkyl groups R2 are straight or branched chain alkyl groups with 1 to 4 C-atoms such as, e.g. methyl, ethyl, propyl, isopropyl, butyl, isobutyl or tertiary butyl.
Alkylene groups D are straight-chain or branched chain, satura-ted alkylene radicals, with up to 5 C-atoms such as, 1,2-methylene, 1,1-tri-methylene, 1,1-tetramethylene or 1,1-pentamethylene. For example, mention may be made of methylene, ethylene, 1,2-propylene~ ethylethylene, trimethylene, tetramethylene, pentamethylene, l-methyltetramethylene, l-methyltetramethylene, l-methyltrimethylene.
The groups already given for R4 can be taken into conslderation as the alkyl groups R9 with 1 to 10 C-atoms.
For salt formation with the free acids ~R2=H), inorganic and organic bases are suitable such as are familiar to the expert for formation of physiological tolerable salts. For example, mention may be made of the following: alkali hydroxides such as calcium hydroxide, alkaline earth hydroxides such as calcium hydroxide, ammonia, amines such as ethanolamine, diethanolamine, triethanolamine, N-methylglucamine, morpholine, and tris-~hydroxymekhyl)-methylamine.

The invention relates to new carbacyclin derivatives, processes for their manufacture and their use as pharmaceuticals.
In U.S. patent 4,~20,632 9-alkylated carbacyclin derivatives are described which possess ant:ithrombosis, antisecretion and bronchiodilatory properties. In addition they have thrombocyte aggregation inhibiting effect. It was found that by replacement of the methylene group in the 3-position of these carbacyclins by oxygen or by extension of the chain in the 9-position hiologically active derivatives are produced which are effective for a longer period of time, have greater selectlvity and possess better efficacy. Derivatives with extended chains in the s-pOsitiOn can be linked to polymeric carriers with only slight loss of biological activity. The compounds in accordance with the invention act in a bronchiodilatry manner and are suitable for inhibiting thrombocyte aggregation, for lowering blood pressure by a process of vasodilation and for :Lnhibiting gastric acid secretion.
The present invention thus provides carbacyclin derivatives with the general formula I:

Alkyl groups R2 are straight or branched chain alkyl groups with 1 to 4 C-atoms such as, e.g. methyl, ethyl, propyl, isopropyl, butyl, isobutyl or tertiary butyl.
Alkylene groups D are straight-chain or branched chain, satura-ted alkylene radicals, with up to 5 C-atoms such as, 1,2-methylene, 1,1-tri-methylene, 1,1-tetramethylene or 1,1-pentamethylene. For example, mention may be made of methylene, ethylene, 1,2-propylene~ ethylethylene, trimethylene, tetramethylene, pentamethylene, l-methyltetramethylene, l-methyltetramethylene, l-methyltrimethylene.
The groups already given for R4 can be taken into conslderation as the alkyl groups R9 with 1 to 10 C-atoms.
For salt formation with the free acids ~R2=H), inorganic and organic bases are suitable such as are familiar to the expert for formation of physiological tolerable salts. For example, mention may be made of the following: alkali hydroxides such as calcium hydroxide, alkaline earth hydroxides such as calcium hydroxide, ammonia, amines such as ethanolamine, diethanolamine, triethanolamine, N-methylglucamine, morpholine, and tris-~hydroxymekhyl)-methylamine.
