AMINO ACID DIAMIDES IN NON a POSITION WHICH ARE USEFUL AS ADJUVANTS FOR ADMINISTRATION OF BIOLOGICAL ACTIVE AGENTS
FIELD OF THE INVENTION r-
The present invention relates to new amino acid diamonds in no a position which are useful as adjutants for administration of biological active ingredients. The compounds under the invention facilitate the oral, intraduodenal, interact logic and pulmonary administration of heparin, low-molecular-weight heparins, very-low-molecular-weight heparins, and other glycosaminogiycans and derivatives.



Primarily those derivatives relative to n=2 and n=5 (WO 97/35480) are claimed as agents that facilitate the oral absorption of biological products.




The applicant has also discovered that the derivatives that have the CI or NO2 substituents in position 3 are at least as active as the derivatives.; that have an OH in position 1.


Figure 3 shows the intracolonic absorption in the rat of the association of the pharmaceutical composition RO-14 with the product of example 4.

To a suspension of 2.14 g (9.63 mmol) of 4-(2-aminobenzoylanr|ino)butanoic acid in 20 ml of dry methylene chloride, add 8.90 g (82.39 mmol) of trimethylsilyl chloride and place the reaction at reflux for 5 hours. Then place the flask in an ice bath and add 1.25 g (12.36 mmol) of triethylamine and a solution of 1.4Q g (8.24 mmol) of 4-methoxybenzoyl chloride dissolved 10 ml of dry methylene chloride. Allow the reaction to stir for 30 minutes in an ice bath and 24 hours at room temperature. Eliminate the solvent at low pressure, add 30 ml of 10% Another the crude product and continue stirring the mixture until the oil has completely disappeared. Immediately acidify with concentrated HCI, filter the resulting solid and wash several times with water and with ether. Purify the reaction product by recrystallization (EtOH/HaO). This yields 2.32 g (79%) of 4-[2-(4-methoxybenzoyl-amino)benzoylamino]butanoic acid as a cream-colored solid.

The activity of all compounds of the examples described above was studied in animals according to the following experimental model:
1. Purpose and rationale
Evaluate the absorption of the test product when administered by intracolonic route to rats, whether or not in the presence of adjutants. The plasma concentration is measured by assaying the Factor Xa-inhibition capacity. Thei rat is used because it is one of the species commonly used in this type of test.
2. Description of the test method
2.1. Experimental system
? Description: Wister male rats, acquired from an accredited supplier.
? Weight 200-250 g
? Age 9 to 11 weeks

2.2. Mode of administration One intracolonic administration.
2.3. Dosage levels and administration volume

? Dosage level 30 mg/kg of test product + 30 mg/kg of adjuvant
? Administration volume 1 ml/kg
2.4. Vehicle
25% (v/v) propylene glycol in bidistllled water. After dissolving the test product along with the adjuvant If applicable, adjust the pH to approximately 7.4 with NaOH.
3.5. Experimental design
The animals will be in fasted state for approximately 18 h with free access to water
The animals will be randomized to the various experimental groups, with one remaining animal as a reserve per group:
On the day of the test, the treatments will be administered by intracolonic route, following anaesthesia with examine. Administration will be done using a catheter of approximately 8 cm, connected to a 1-mi syringe. The catheter will be introduced in its entirety into, the colon through the anus and the test product will be administered levy into the colon.
Following the administration of the test product, within the times established in the table, a citrated blood sample (3.8% at a ratio of 1:9) will be drawn by intracardiac puncture under anaesthesia with ketamine.
Blood centrifugation: 3000 rpm, 10 minutes, 4° C. Plasma freezing (-20 + 5° C) until determining the anti-Factor Xa activity.
A control group that will receive no treatment will be included, simply that one blood sample will be drawn per animal under the same conditions as the treatment group, with considered to be the baseline value of anti-Xa activity.
The anti-Xa activity will be assayed by the chromomeric method (anti-Fax activity assay kit).
3, Evaluation of the results
The mean, the standard deviation (RSD) and the standard error. of the mean of each experimental group will be calculated for each parameter. If considered adequate,

the values obtained in the different experimental groups will be compared by a statistical analysis.
