Many acute and chronic diseases, injuries and medical interventions are associated with pain, requiring the use of analgesics. Pain is divided into acute and chronic. The choice of anesthesia is determined by several factors, the main of which are the etiology, intensity, type of pain, the individual characteristics. The intensity of the pain determines the choice of appropriate pain relief analgesic potential. Neopioidnye analgesics, non-narcotic drugs and releasing without a prescription, used to treat acute pain and chronic pain syndromes of low intensity [1, 2]. Non-opioid analgesics include the five drugs pharmacological groups: NSAIDs, selective cyclooxygenase-2 inhibitors (COX-2), pyrazolone derivatives, derivatives of paracetamentol and flupirtine.

One of the most used and the closest the technical result of the proposed tool is diclofenac NAT�Oia (Diclofenac Na), which is selected as the comparison drug [1, 2].

There are contraindications and limitations to the appointment of the majority of analgesics [1-4].

The problem solved by the present invention is to expand the Arsenal of analgesics with first synthesized substances.

The task is achieved by the use of newly synthesized substances 4,10-bis((±)-5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carbonyl)-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane (DKTAiW) as analgesic agents.

According to computer modeling and screening studies of derivatives of 2,4,6,8,10,12-hexaazatetracyclo exhibit diverse biological activity [5, 6].

DKTAiW is a frame polyamide - derived 2,4,6,8,10,12-hexaazatetracyclo. The substance was first obtained by acylation available industrial 2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane the acid chloride of 5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carboxylic acid

The process is performed in the environment of acetonitrile at the boiling point of the reaction mass.

The structure DKTAiW fully confirmed by physico-chemical methods of research.

The technical result of the invention is a substance, method for its production and identification of analgesic actions of the new non-toxic analgesic agents.

Proposed in the invention, the analgesic agent DKTAiW synthesized in Institute of problems of chemical and energetic technologies SB RAS, Biysk). The prototype on substance and method for its production is absent.

Study of analgesic activity of 4,10-bis((±)-5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carbonyl)-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane (DKTAiW) compared to the reference drug diclofenac sodium�

Experiments were performed on 52 outbred mice CD-1 both sexes (7-8 weeks, weight 20 g) the first category is conventional, obtained from the nursery of the Department of experimental biomedical modeling, Institute of pharmacology, SB RAMS (certificate from 07.10.2012, veterinary certificate 270 S. No. 0007293 from 28.11.2013). The keeping of animals and the design of the experiments were approved by the Ethics Committee of the Institute of pharmacology named after E. D. Goldberg" SB RAMS and adheres to the rules adopted by the European Convention for the protection of vertebrate animals (Strasbourg, 1986); Order of the MOH of the Russian Federation No. 708 H of August 28, 2010; Guidance for conducting pre-clinical trials of drugs(2012) [2, 7].

Test "acetic cramps" (Abdominal constriction test) is aimed at the study of the acute visceral and deep somatic pain. Specific pain response - "cramps" (characteristic movements of animals, including reduction of abdominal muscles, alternating with relaxation, stretching of the hind limbs and can Flex back) - caused by intraperitoneal injection of 0.75% acetic acid (GOST 61-75) to mice at a dose of 0.1 ml/10 g of body weight [2, 8]. Analgesic effect was assessed by the ability of potential drugs (within 15 min after injection) to reduce (in %) number of writhing in comparison with the control group animals (criterion �effektivnosti - reducing the pain response by at least 50%) and delayed the time of onset of the pain response. Euthanasia of the animals after the experiments performed in the cranio-cervical dislocation.

Determination of acute toxicity 4,10-bis((±)-5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carbonyl)-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane (DKTAiW)

In determining acute toxicity DKTAiW injected 6 outbred mice-females and 6 outbred mice-males CD1 intragastrically once a maximum dose of 5000 mg/kg in 0.5 ml of solvent (0.5 ml of Dimexidum and 5.5 ml of distilled water). Within 2 weeks, no deaths were observed, mice had no deviations in health status and behavior, therefore, the test substance is DKTAiW referred to hazard class 4 - "non-toxic assets" in accordance with GOST 12.1007-76 "Hazardous substances. Classification and General safety requirements" and "guidelines for conducting pre-clinical trials of drugs, 2012". In connection with the inability to determine the LD50 for screening assessment of the influence of the test substances on the development of pain response DKTAiW was administered to mice by gavage at a dose of 50 and 100 mg/kg. Used daily dose of diclofenac sodium for mice (10 mg/kg) corresponded to the average daily dose for humans (according to the instructions for use Diklo�of Anak sodium). Each animal within the group were assigned a unique number from 1 to 10, we will use the labels focaccina. The mice were divided into groups randomly, using as a criterion of body weight, so that the individual weight should not deviate from the average value within the same sex more than ±10%. Data (weight and number) of animals selected were ranked in descending order of weight, using the computer program Excel with the SORT command.

In the experiments used the following groups of outbred female mice of CD1:

1. Animals received the solvent in the total volume of 0.5 ml/mouse daily intragastrically by gavage for four days, the last day of the introduction was carried out for 1 h before injection of 0.75% R-RA acetic acid (n=10);

2. Animals received diclofenac sodium at the dose of 10 mg/kg in a volume of solvent of 0.5 ml/mouse daily intragastrically by gavage for four days, the last day of the introduction was carried out for 1 h before injection of 0.75% R-RA acetic acid (n=10);

3. Animals were injected DKTAiW dose of 50 mg/kg in a volume of solvent of 0.5 ml/mouse daily intragastrically by gavage for four days, the last day of the introduction was carried out for 1 h before injection of 0.75% R-RA acetic acid (n=10);

4. Animals were injected DKTAiW at a dose of 100 mg/kg in a volume of 0.5 ml solvent/mouse daily nutrigold�but through the probe within four days on the last day of the introduction was carried out for 1 h before injection of 0.75% R-RA acetic acid (n=10).

Statistical processing of obtained results was performed using standard methods of variation statistics. Intergroup differences were assessed using nonparametric Mann-Whitney test (U-test). Differences were determined at 0.05% confidence level [9].

The amount of acetic "writhing" 27,40±3,13 and latent time of occurrence was 276±15 seconds show the development of a full-fledged pain response in untreated animals (table. 1). Preventive administration to mice of diclofenac had led to reduced levels of pain response by 33.6%, as the number of "writhing" in this group was statistically significantly decreased in 1,5 times in comparison with the corresponding figure in the control group. The development of pain response was not different from that of the values in untreated animals. The results of the reference control correspond to the data of literature.

The use DKTAiW dose of 50 mg/kg reduced the severity of the pain response by 39.1% (P<0.01), showed a statistically significant decrease in latency time to the onset of the pain response relative to similar result, untreated group (table. 1).

In the case of the introduction DKTAiW at a dose of 100 mg/kg the value of the inhibition of pain response increased�subscribe to 57.7%. It should be noted a statistically significant decrease in the number of acetic "writhing" in 2.4 and 1.6 times respectively compared to the same indicators in animals treated with the solvent and diclofenac (table. 1). The test substance DKTAiW (100 mg/kg) had a preferential activity compared to the reference drug diclofenac sodium (57,7% versus 33.6 percent).

Identified analgesic activity of new substances 4,10-bis((±)-5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carbonyl)-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane (DKTAiW), comparable with the efficacy of diclofenac sodium at a dose of 50 mg/kg and higher dose of 100 mg/kg on models of chemical pain of peritoneal irritation in mice.

It is shown that preventive course intragastric gavage application of 4,10-bis((±)-5-benzoyl-2,3-dihydro-1H-imidazo[1,2-a]pyrrole-1-carbonyl)-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,03,11That 05,9]dodecane (DKTAiW) at a dose of 100 mg/kg reduced the severity of the pain response by more than 50%, which makes it a promising material for creation on its basis substance and further study as analgesic agents [2].
