Neutralization, if possible, remaining free carboxyl groups is carried out with the help of inorganic bases (for example, hydroxides, carbonates or bicarbonates, for example sodium, potassium, lithium, magnesium or calcium and/or organic, glucamine, N-methyl - and N,N-dimethylglycine, and also amino acids, such as lysine, angina and ornithine or of amides of originally neutral or acidic amino acid.

To obtain a neutral complex compounds can be added, for example, to the acid complex salts in aqueous solution or suspension sufficient basis to reach the neutral point. The resulting solution may then be one stripped off in vacuum to dryness. Often the advantage is that the obtained neutral salt by adding solvents, miscible with water, such as lower alcohols (methanol, ethanol, isopropanol and others), lower ketones (acetone and others), simple polar ethers (tetrahydrofuran, dioxane, 1,2-dimethoxyethane and others), precipitated and get so easily allocated and well cleaned crystals. Especially preferred was adding the desired base during the complexation reaction mixture and as a consequence saving a single process step.

The subject invention are further pharmaceutical agents that contain at least one physiologically acceptable compound of General formula I, optionally with conventional galenovye add the integrated connection according to the invention, if necessary, with additives conventional galenic additives, suspended or dissolved in aqueous medium and then the suspension or solution optionally sterilized. Suitable additives are, for example, physiologically acceptable buffers (such as, for example, tromethamine), additives, complexing agents or weak complexes (such as, for example, diethylenetriaminepentaacetic acid or complexes of Sa related to the metal complexes according to the invention), or, if necessary, electrolytes, such as sodium chloride, or, if necessary, antioxidants, such as ascorbic acid.

If for enteral or parenteral administration, or for other purposes desired suspension or solution means according to the invention in water or physiological salt solution, then they are mixed with one or more traditional galenovye auxiliary substances [for example, methylcellulose, lactose, mannitol] and/or detergents [for example, lecithins, Tween® , Myrj® ], and/or aromatic substance (substances) for the correction of taste [for example, essential oils].

In principle it is also possible to obtain pharmaceutical without allocation of complexes. In each case must be one from uncomplexed toxic metal ions.

This can be, for example, is provided with color indicators, such as xrenovy orange, through the control titration during the retrieval process. The invention relates also to a method for production of complex compounds and their salts. For security you can remove the selected set.

The pharmaceutical agents according to the invention preferably contain 0.1 µmol - 1 Mol/l of the complex and injected, typically in amounts of 0.0001-5 mmol/kg They are intended for enteral and parenteral administration. Complex compounds according to the invention are applied:

1) for NMR diagnostics in the form of their complexes with the ions of elements with atomic numbers 21-29, 39, 42, 44 and 57-83;

2) for radiodiagnostics and radiotherapy in the form of their complexes with the radioisotopes of elements with atomic numbers 27, 29, 31, 32, 37-39, 43, 49, 62, 64, 70, 75 77.

The means according to the invention meet the diverse requirements of suitability as contrast media for nuclear spynomore. So, they are preferably suitable for improving the sharpness of the obtained image obtained by nuclear spynomore, after oral or parenteral administration by increasing intensively small number of foreign particles, and good tolerability, which is necessary to maintain the noninvasive nature of the research.

Good solubility and low osmolarity means according to the invention allows to obtain a highly concentrated solutions in order to keep the volume load of the circulation in the required boundaries and to compensate for the dilution due to body fluids. Further, the means according to the invention have not only a high stability in vitro, but also remarkably high stability in vivo, so that the release or exchange of ions, which are themselves poisonous associated in the complex during the time when the new contrast agent will be fully withdrawn, occurs extremely slowly.

In General, the means according to the invention for use as NMR diagnostic dispensed in quantities from 0.0001-5 mmol/kg, the preferred way of 0.005-0.5 mmol/kg, Particularly low doses (below 1 mg/kg body weight) organ-specific NMR-diagnostico used, for example, for the detection of malignant tumors and heart attacks heart.

Further, the complex compounds according to the invention can be used preferably as a reagent sensitivity and as reagents funds due to its favorable radioactive properties and good stability contained in complex compounds. The details of this application and dosage are described, for example, in "Radiotracers for Medical Applications", CRC Press, Boca Raton, Florida.

Connection and means according to the invention can also be used in positron emission tomography, which uses positron-emitting isotopes, such as⁴³Sc,⁴⁴Sc,⁵²Fe⁵⁵And⁶⁸Ga (Heiss, W. D.; Phelps, M. E.; Positron Emission Tomography of Brain, Springer Verlag Berlin, Heidelberg, New York, 1983).

Compounds according to the invention are suitable for the differentiation of malignant and benign tumors in hematoencephalic barrier.

They differ in that fully removed from the body and, thus, are well-tolerated.

Because of the substances according to the invention are concentrated in malignant tumors (there is no diffusion in healthy tissue, but remains high transmission ability of tumor vessels), they can contribute to the radiation therapy of malignant tumors. It differs from the corresponding diagnosis only by the number and type of isotopes. The objective is the destruction of tumor cells due to the energetically enriched shortwave radiation with the minor radius of action is INIA) with ionizing radiation (e.g., x-ray or neutron radiation. Due to this effect significantly increases the local radiation dose on the place where is located the complex of metals (for example, malignant tumors). In order to create the same dose of radiation in malignant tissues, the use of such metal complexes can significantly reduce radiation exposure to healthy tissue and, thereby, to avoid side effects for patients. Conjugates of metal complexes according to the invention therefore also suitable as radiosensitive tool in radiation therapy of malignant tumors (e.g., using Mossbauer effects or therapy associated with the capture of neutrons). Suitable-emitting ions are, for example,⁴⁶Sc,⁴⁷Se⁴⁸Sc,⁷²Ga⁷³Ga and⁹⁰Y. Corresponding with low half-life time-emitting ions are, for example,²¹¹Bi²¹²Bi²¹³Bi and²¹⁴Bi, preferably²¹²Bi. Suitable ion radiating protons and electrons is¹⁵⁸Gd, which can be obtained from the¹⁵⁸Gd by capture of neutrons.

If the application is 6, (1968), page 787], the Central ion must be derived from the Mossbauer isotope, such as⁵⁷Fe or¹⁵¹Unit.

With the introduction of the means according to the invention in vivo can be used together with an appropriate carrier, e.g., serum or physiological saline, and together with another protein, such as serum albumin human. The dosage will depend on the type cellulare violations, used metal ion and method of forming image.

The means according to the invention is usually introduced parenterally, preferably intravenously. They can also be entered, as previously explained, intravasal or interstitielle/interdermal depending on the vessels or tissue of the body should be examined.

The means according to the invention is suitable as contrast agents for x-rays, and it should be particularly emphasized that using these drugs in the process of biochemical and pharmacological research does not appear signs of reactions anafilaktichesky of the type known from iodine-containing contrast agents. Especially valuable they are due to adsorption properties in the areas of higher stress in the tube for digital strcontrolid funds by analogy, for example, with meglumin-diatrizoate in the amount of 0.1-5 mmol/kg, preferably 0.25 to 1 mmol/kg

This way it was possible to synthesize new complexing agents, metal complexes and salts of metal complexes, which open new possibilities in diagnostic and therapeutic medicine.

EXAMPLE 42

Kinematics excretion from the blood contrast agents

Kinematics excretion from the blood of contrast agents was investigated in rats (Han. Wistar, Schering SPF, approximately 250 g body weight). To do this, after a single intravenous injection (via a Caudalvene) substance (dose) is determined during the time up to 300 min p.i using ICP-AES. Pharmacokinetic parameters: volume of distribution (Vss), total factor purification (CLtot) and the period of providentia (t) was calculated using special computer programs (TOPFIT 2.0; Thomae, Schering, Godecke), and it is based on one - and twocompartment distribution model.

Compared to Dy-DTPA (analog dysprosium Magnevist) fluoride compounds according to the invention (for example, example 1B) is clearly more slowly eliminated from the blood and, in addition, have a smaller distribution (see also Fig. 1 and table 1).

It should be noted that these compounds unexpectedly have extended rately in the blood and therefore, being a "contrast agent blood depots are suitable for imaging of blood vessels using the appropriate technique, in relatively small dosages50 mmol per kg of body weight.

EXAMPLE 43

Enrichment of lymph nodes in Guinea pigs

Various fluorine-containing complexes of gadolinium and manganese have been tested over time from 90 minutes to 24 hours after injection subcutaneously (2.5 to 10 mmol of total gadolinium/kg of body weight, hind paw s.c.) on the subject of stimulation Guinea pigs (complete Freund-adjuvant; accordingly 0.1 ml i.m. at right and left femora and tibia; two weeks before giving control of the dose of the substance to enrich lymph nodes in three contiguous lymph nodes (popliteal, inguinal, iliac). Thus were obtained the results given in table 2 (the determination of concentrations of gadolinium using ICP-AES).

Table 2 shows that a high concentration of contrast agents observed in three successive lymph node.

EXAMPLE 44

The image of the lymph nodes (MRI) after interstitial administration of contrast material

In Fig.1.1 shows Mr images of lymph nodes: popliteal and inguinal before (left side: precontrast), and after 120 minutes (right side) after subcutaneous (Guinea pig, hind paw, space, Breakfast is minimizetotray ether) (10 mmol Gd/kg body weight). T¹-spin-echo images (TR 400 ms, TE 15 MS) make more evident the strong increase of the signal in the lymph nodes, popliteal and inguinal - injected (straight arrow) compared with penjelasannya (curved arrow) side of the body or with precontrast image.

EXAMPLE 45

Excretion of contrast medium after introduction i.p.

After the introduction of the perforated gadolinium complex according to the invention (100 mmol of total gadolinium/kg of body weight) in the peritoneal region of the rat was investigated within 14 days after the introduction of the delay of the metal in the liver and in the body. While this study used a fluoride compound 2B). After 14 days after the injection, the concentration of gadolinium in the liver was 0.22%, while in the rest of the body 1/1% of the administered dose.

In contrast, Gd-DPTA-polylysin as the polymer material is not fully displayed. After 14 days, the body is still 7% of the administered dose.

EXAMPLE 46

Definition T¹relaxation of selected compounds

Relaxation following compounds determined using a Minispec pc 20 (20 MHz, 0,47 T) at 37°C in water and in human plasma and compared to Gd-DTPA-polylysine and mud-nevist® as a comparative substance. (see tab.3).

In this experiment, on the body of negritude was to identify the minimum effective dose of the compound of example 33 for use in interstitial limfografii. In the first part of the experience directly on one animal (in each case with the introduction on the one hand, the 6 points above or below the hips) compared two doses (10,0 and 2.5 mmol Gd/kg). In the second part of the experiment was performed in a single dose of 1.0 µmol/kg and was administered subcutaneously standardized in two places (5 cm below the knee) with outer and inner side of hind limbs.

Confirmed the excellent suitability of the compounds according to example 33 to obtain regional lymph nodes (inguinal, iliac and para-aortic) after intersticialnom injection in the hind leg of the dog. Achieved significant increase in signal right after the introduction, through which approximately 60-90 min, reached a maximum. Along with contrast lymph nodes up to the maximum intensity projection was possible to observe a clear enhancement of the image of the lymphatic vessels.

With the direct comparison of two doses of 10.0 and 2.5 mmol Gd/kg not found virtually no difference in the signal intensity. On the contrary, the minimum dose of 1 çmol/kg (with an amended scheme, in the representation of the lymph glands (MRT) after intersticialnom contrast to the Guinea pig

In Fig. 3 and 4 show Mr images of the popliteal, inguinal and iliac lymph nodes before (baseline: precontrast) and after 30 min, 5 or 6 h after interstitial injection (subcutaneously in the interdigital space of the hind legs) Guinea pig 10,0 and respectively 2.5 mmol Gd/kg of body weight of the compound of example 33 to stimulate the lymph nodes (full beta-blockers: 0.1 ml intramuscularly in the right and left side above and below the hip; 2 weeks prior to the introduction of the analyzed compounds). Images of T₁-balanced gradient echo (TR 10 MS, TE 5 MS,26°) revealed a strong increase of the signal in different groups of lymph nodes (arrows) compared with precontrast image. Corresponding values of the signal gain (in % of value of precontrast) are given in table 4.

EXAMPLE 49

The image of the tumor (MRT) after intravenous administration of contrast material rabbit

In this experiment investigated the suitability of the compound of example 33 to obtain images of liver tumors and compared with the effect of the standard contrast agent Magnevist 0 company Schering AG, Berlin). This used the rabbit, which is 4 weeks prior to injection of 100 mmol/kg Magnevist after 30 min after injection in healthy liver, and in the tumor could be observed only a slight increase of the signal. Signal enhancement in healthy liver ranged from 5-30 min after injection of approximately 25% in tumor 35-66%.

In contrast, injection of the compound from example 33 was led to significantly greater signal amplification in a healthy liver (approximately 150% after 15-60 min after injection) compared with tumors (approximately 65-85% after 15 min - 24 h after injection). Therefore, the contrast between healthy tissue and tumor increases (increase in the ratio of the signal intensity of the liver/tumor from 1.6 (0 min) to 2.6 (15 after injection)).

In Fig. 5 and 6 shows precontrast Mr image of the liver (tumor) and after 15 min, 30 min and 60 min after intravenous administration of 100 μmol Gd/kg of body weight in the form of the compound of example 33 and drug Magnevist. Images of T₁-balanced gradient echo (1.5 T; TR/TE 100/4,6 MS,70°) revealed a strong signal rise in healthy liver tissue compared to tissue tumors after administration of the compound of example 33. Corresponding values of the signal gain (in % of precontrast) are given in table 5.
