A new drug containing a cyclopentylaldehyde derivative and composition containing same.
This invention is concerned with a "new drug which belongs to the family of the cyclo-5 pentyl-aldehyde derivative, and with a therapeutical composition containing a cyclopentylaldehyde derivative as active ingredient.
More precisely the invention relates to a cyclopentyl-aldehyde derivative useful in therapy, 10 which is selected from the group consisting of a)compounds of the general formula
A-X
(I)
$ ^
;r i zr y wherein X and Y, which can be the same or different represent CHO, CH^OH or COOH; Z represents a C^-C^ 15 alkyl group; A represents -CH^-, ^ CcrCH^ or ^CH(CH^);
and b) their geometrical isomers.
Compounds of formula I are known compounds which can be prepared either by synthesis or 20 by extraction from a plant belonging to the Labiatae family such as the Teucrium marum , Teucrium polium aild Teucrium montanum species. For instance they can be extracted from Teucrium marum according to the method disclosed by PAGNONI et al., in Aust, J. Chem, (1976), 25 29, pages 1375-1381, article wherein their pharmaceutical properties are not described •
Now it has been surprisingly found that cyclopentyl-aldehyde derivatives according to formula I are (i) active as bacteriostatic, bacteri-30 cide, antispasmodic, antianaphylactic and antiphlogistic agents, and (ii) useful in particular in the treatment of human beings and warm-blooded animals suffering

190628
from infections diseases induced by"Gram(+)and Gram (-)" germs,and allergies such as hay fever.
aldehyde derivatives of formula I are more interesting, from a pharmaceutical point .of view, than the Teucrium marum extracts according to US patent No. k 151 278.
the definition of the general formula I, can be cited the following ones:
- Ex. 1: cK -( 2-f ormyl-3-niethyl-cyclopentyl)-acetaldehyde (X = Y=CHO; A = CH2; Z = CH^) ,
- Ex. 2: 2-( 2-hycLroxymethyl-3-methyl-cyclopentyl) -ethanol ( X = Y = CH2OH;A = CH2; Z = CH^) ,
- Ex. 3^ °C~( 2-carboxy-3-methyl-cyclopentyl)- acetic acid (X = Y = COOH; A = CH2; Z = CH ) ,
- Ex. 4: Q<( -(2-formyl-3-niethyl-cyclopentyl)-acrylaldehyde (X = Y = CHO; A = )C = CH2; Z = CH^) ,

the"cis~trans" isomer being, in a general manner, more active than the "trans-cis"one.
The preferred compounds are those of examples 1 and 4. The most interesting one, from a 5 therapeutical point of view, is the compound of example
4.
The best mode for preparing the "acryl" compounds (A=^ C = CH^) consists in (i)
extracting o<-(2-formyl-3- methyl-cyclopentyl)-acrylal-10 dehyde from a Teucrium species such as Teucrium marum, Teucrium polium, Teucrium montanum, and (ii) transforming CHO into CH^OH by reduction or into COOH by oxidation. The compounds wherein A is CH(CH_)
such as example 7 are obtained by catalytic hydrogenation 15 of C =CH2* The compounds wherein A is CH2 are in particular prepared by synthesis according to a method known .per se.
PREPARATION I
obtention of -(2-formyl-3-methyl-ayclopentyl)-acr^l-20 aldehyde (Example 4)
1210 g of dried and ground Teucrium polium (entire plant) were extracted in a column successively with 7*35 1 of hexane and 7-25 1 of chloroform. The chloroform extract was evaporated to dryness 25 under vacuum and the residue thus obtained (47 g)
was steam distilled. The distillate was saturated with sodium chloride then extracted with chloroform. After drying on Na^SO^ the chloroform was distilled off under reduced pressure (0.3 mm Hg) to give 7.3 g (yield 0.

PREPARATION II
Obtention of ( 2-formyl-3-methyl-cyclopentyl) -acryl-aldehyde (example 4)
kg of dried and ground Teucrium marum (entire plant) were extracted by lixiviation in a
glass column (height: 2m; diameter: 0.225 m) fed in solvent by means of a pomp having a delivery of 10 1/h.
Two solvents were successively used: hexane (170 1)
then chloroform (170 1} . The hexane extract was discarded.
The chloroform extract was evaporated to dryness
under vacuum in order to obtain a brown oily residue
(640g) which was steam distilled. The distillate was saturated with NaCl when extracted with chloroform.
The chloroform phase was dried over NaSO^, the solvent was evaporated and the remaining oil was distilled
(under 1 mm Hg at 60-78°C) to give 42 g of a yellow 25° C
oil (n^ = 1.4842) which comprised:
- 87% by weight of the "cis-trans" isomer , and
- 13% by weight of the "trans-cis" isomer.
PREPARATION III
Obtention of 2- (2-hydroxymethyl-3-methyl-cyclopentyl) -2-propen-l-ol (example 5)
By reduction of the "cis-trans"
isomer of example 4 (1.4g) in solution in CH OH (25ml)
/ \ U
with NaBH^ (1.7 g) , the cis-trans isomer of example 5 30 (1019 g) is obtained in the form of an oil. According to the same method the trans-cis isomer of example 5 is

prepared from the trans-cis isomer of example 4.

PREPARATION IV
Obtention of 2-(2-hydroxymethyl-3-methyl-cyclopentyl)-propan-l-ol (example 7)
The"cis-trans" and respectively "trans-5 cis" isomers of example 7 were obtained by hydrogenation on PtOg of the "cis-trans" and respectively "trans-cis" isomers of example 5 according to the method disclosed by PAGNONI et al.

c) Antibronchospasmic activity
Guinea pigs (20 animals (weighing 300 - 500 g) per dose and per product to be tested) are preliminary subjected to an aerosol of Example 4 (50 g/1 in a water-ethanol solution) or Promethazine (a reference product) for 10 minutes. Then the animals are subjected individually to an histamine aerosol (3g/l of histamine in an aqueous medium containing 200g/l of glycerin)„ The time comprised between the beginning of the exposure to the histamine aerosol and the apnea with fall of the animal is measured.The control batch received only the histamine aerosol. The results given in table II show that Example 4 exhibits a bronchodilating effect which opposed the broncho-constrictor effect of histamine.

d) Antianaphylactic activity in vitro
Male guinea pigs are sensitized by an i.p. injection of lOO mg/kg of ovalbumen in an equal volume of Freund's adjuvant. Four weeks after the animals are slaughtered, each ileum is recovered and placed at 33°C in a Thyrode medium. Constriction is.obtained by addition of 200 jig of albumen to the liquid of surviving. The amplitude of the constrictions of the control ileum is compared with the amplitude of the constrictions after putting into contact example 4 for 2 minutes. The results given in Table III show that example 4 reduces the constriction amplitude of isolated guinea pig ileum, said reduction being statistically signifipant.
in vivo
Guinea pigs (male or female) are sensitized as indicated above with ovalbumen four weeks before the beginning of the experiment. Each animal is subjected to an oyalbumen aerbsol (obtained from an aqueous medium containing 50g/l of ovalbumen).
The anaphylactic shock comes out. by apparition

The invention includes within its scope a therapeutic composition comprising, in association with a physiologically acceptable excipient, a pharmaceutically effective amount of a cyclopentyl-aldehyde derivative of formula I
Such-a composition can be administered orally in the form of tablets, dragees, syrups and potable ampoules, by injection, and by spray.
The best mode for carrying out the invention consists in administering to human beings and warm-blooded animals the compound of example 4 or its "cis-trans" isomer, preferably in the form of spray or aerosol (in solution in carbitol or in suspension in freon or in a freon-alcohol mixture). When a spray or an aerosol is used it will contain from 0.1 to 10% of example 4 or its "cis-trans" isomer.
Example 4 and its "cis-trans"isomer can also be administered per os in the form of soft capsules (in oily solution) gelules (with a viscous or solid excipient), the preferred exipient being polyoxy-ethylenated oleic glycerides obtained by alcoholysis of a natural vegetal oil and which are sold under the name of LABRAFIL.
The corpounds of Formula I, in particular Example 4 and its "cis-trans" isomer, are useful in the treatment of infectious diseases, allergies such as hay fever and asthma (taking into account their antianaphylactic activity), inflammations and algiae.
