Also described drug, possess antibacterial properties, on the basis of this connection. The technical result - the new form 8-cyan-1-cyclopropyl-7-(1S,6S-2,8-diazabicyclo[4.3.0]nonan-8-yl)-6-fluoro-1,4-dihydro-4-oxo-3-quinoline-carboxylic acid, which has a good solubility in water. 3 N. p. and 2 C.p. f-crystals, 6 ill., table 2.

The present invention relates to polyhydroxylated 8-cyan-1-cyclopropyl-7-(1S,6S-2,8-diazabicyclo[4.3.0]nonan-8-yl)-6-fluoro-1,4-dihydro-4-oxo-3-quinoline-carboxylic acid, its preparation and to its containing antibacterial agent. 8-Cyan-1-cyclopropyl-7-(1S,6S-2,8-diazabicyclo[4.3.0]nonan-8-yl)-6-fluoro-1,4-dihydro-4-oxo-3-quinoline-carboxylic acid of the formula (I) will be denoted as CCDC.

CCDC is known from DE-A 19 633 805 or PCT application No. 97 903 260.4. It is obtained respectively by the reaction of 7-halo-8-cyan-1-cyclopropyl-6-the Hal - fluorine or preferably chlorine

with

(1S,6S)-2,8-diazabicyclo[4.3.0]nananom formula (III)

in the presence of an auxiliary base and a suitable solvent.

With CCDC formula (I) it is possible to achieve solubility in water of about 0.02% (weight/weight). This solubility is not sufficient for practical applications (solutions for injection or oral forms of application). For many other quinoline-carboxylic acids known that they are used in recipes in the form of certain salts. As salts are used at the same time, on the one hand, metal salts of quinoline-carboxylic acids (for example, alkali carboxylates), and acid adducts (protonation of the main center of balance amine substituted quinoline-carboxylic acid). As such acid adducts are often used, for example, mesylates, tozilaty and hydrochloride. Hydrochloride particularly simply manufactured, pharmaceutically acceptable and have clearly better solubility than the neutral connection.

CCDC-hydrochloride of the formula (IV)

known from WO 97/31001.

This connection can be characterized by its x-ray diffractor the gram powder represented as shown in Table 1 reflexes (2(2 theta)) high and medium intensity ( >30% relative intensity).

X-ray diffractogram of the powder CCDC-hydrochloride of the formula (IV) is also shown in Fig.1.

Melting point CCDC-hydrochloride, was determined using DTA, is 305 - 307C (decomposition). Differential-thermal chart shown in Fig.2.

The IR spectrum of the CCDC-hydrochloride of the formula (IV) shown in Fig.3.

CCDC-hydrochloride of the formula (IV) can be obtained in principle known methods. So, for example, possible solution CCDC formula (I) in water mixed with one mol equivalent of Hcl and the solution to evaporate to dryness. Another method is that the ethyl ester of 8-cyan-1-cyclopropyl-7-(1S,6S-2,8-diazabicyclo[4.3.0]nonan-8-yl)-6-fluoro-1,4-dihydro-4-oxo-3-quinoline-carboxylic acid of formula (V)

its shades flooded with hydrochloric acid and precipitated CCDC-hydrochloride of the formula (IV) is allocated.

With CCDC-hydrochloride of the formula (IV) may be obtained solubility in water approximately equal to 2.8% (wt/wt). However, it is better soluble in water than CCDC formula (I), but not for all forms in the desired quantities.

According to this invention, it was found that the orim in the water. With CCDC-polyhydroxylated formula (VI) can be prepared 19% (wt/wt) solution in water.

The object of the invention is a crystalline CCDC-polyhydroxystearic formula (VI), which, among differs in that it has the x-ray powder diffraction pattern as shown in table 2 reflexes of high and medium intensity (>30% relative intensity)

X-ray diffractogram of the powder CCDC-polyhydroxylated formula (VI) shown in Fig.4.

CCDC-polyhydroxylated formula (VI) according to the invention, moreover, characterized in that the temperature of its melting point, determined by differential thermal analysis, is 278-280C. the Corresponding differential-thermal chart shown in Fig.5.

CCDC-polyhydroxylated formula (VI) according to the invention, moreover, differs in that it has an infrared spectrum measured in CVG, shown in Fig.6.

CCDC-polyhydroxylated formula (VI) unknown crystalline forms can also in principle be manufactured in a known manner, for example, mixing an aqueous solution CCDC formula (I) with 0.5 mol equivalent of Hcl and evaporate the solution to dryness.

In exactly the same way in principle, it is possible to mix CCDC formula (I) and CCDC formula (IV) in the molar regarding the pairing dry.

In addition, according to this invention it has been found that unexpectedly can directly make CCDC-polyhydroxylated formula (VI), which is characterized through the above x-ray diffraction the diffraction pattern of the powder and the above differential-thermal chart.

The object of the present invention thus also is CCDC-polyhydroxylated formula (VI), which differs from that obtained by the reaction of 7-halo-8-cyan-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-3-quinoline-carboxylic acid of formula (II), in which the halogen is fluorine or preferably chlorine, with (1S,6S)-2,8-diazabicyclo[4.3.0]nananom formula (III), optionally, in the presence of a base in one of the following solvents or mixtures of solvents:
