Definitions
- the invention relates to medicine, namely to medicines having analgesic effect.
- Known analgesics which are pharmacologically non-narcotic analgesics, such as acetylsalicylic acid, analgin and others [1].
- ED 50 acetylsalicylic acid
- LD 5 o acute toxicity
- acetylsalicylic acid is low activity and gastrotoxicity; analginum - possible inhibition of hematopoiesis, up to complete agranulocytosis.
- diclofenac sodium The disadvantages of diclofenac sodium are gastrointestinal upsets and gastrotoxicity.
- the problem to which the invention is directed is to search for new effective low-toxic drugs with analgesic activity.
- R b R-2, R 3 may be the same or different; and may be a hydrogen atom, an alkyl group, a nitro group, a halogen.
- compound 1a can be obtained in 78% yield by reacting isopulegol 2 with thiophene-2-carbaldehyde in the presence of commercially available montmorillonite clay K 10, without any preliminary chemical modification, and in the absence of microwave irradiation by simply maintaining the reaction mixture without solvent for 1-2 hours
- Derivatives of compound 1a along the aromatic ring can be synthesized by the reaction of isopulegol 2 with substituted thiophene-2-carbaldehydes in the presence of clay K10.
- various spatial isomers of compound 2 can be used as starting materials, including those with optical activity.
- the analgesic activity of the compounds of general formula 1 was studied on models of visceral pain "vinegar cramps” and thermal irritation "hot plate” on white outbred mice weighing 20-22 g in groups of 8 animals with a single injection in doses of 1-g20 mg / kg
- Acetic cramps were reproduced by intraperitoneal injection of 0.75% acetic acid in 0.1 ml per animal. Assessment of activity was carried out by the number of writhing for 3 minutes
- Example 2 by the interaction of 0.300 g of isopulegol 2 with 0.25 g of 3-methylthiophene-2-carboxaldehyde in the presence of 1.1 g of clay K10, 0.381 g (70%) of compound 16 was obtained within 120 minutes.
- Example 1 the interaction of 0.300 g of isopulegol 2 with 0.25 g of 5-methylthiophene-2-carboxaldehyde in the presence of 1.1 g of clay K10 within 120 minutes yielded 0.386 g (71%) of compound 1c.
- Example 2 the interaction of 0.300 g of isopulegol 2 with 0.37 g of 4-bromothiophene-2-carboxaldehyde in the presence of 1.4 g of K10 clay produced 0.499 g (74%) of 1 g in 120 minutes.
- Example 2 the interaction of 0.300 g of isopulegol 2 with 0.37 g of 5-bromothiophene-2-carboxaldehyde in the presence of 1.4 g of clay K10 within 120 minutes gave 0.512 g (76%) of compound 1d.
- Example 2 by reacting 0.400 g of isopulegol 2 with 0.407 g of 5-nitrothiophene-2-carboxaldehyde in the presence of 1.6 g of clay K10, 0.400 g (50%) of compound 1 hail were obtained in 60 minutes.
- Example 7 The study of the analgesic activity of the compounds of General formula 1 in the test "vinegar cramps”.
- the experiment was carried out on outbred male mice weighing 22-25 g.
- the experimental groups were formed of 8 animals each. Acetic cramps were reproduced by intraperitoneal injection of 0.75% acetic acid in 0.1 ml per animal.
- the test agents were administered intragastrically once an hour before model reproduction.
- the control was animals with the introduction of only acetic acid.
- Assessment of activity was carried out by the number of writhing for 3 minutes
- Example 8 The study of the analgesic activity of compound 1 in the test "hot plate”.
- mice were performed on outbred male mice weighing 22-25 g.
- the studied agents were administered intragastrically once an hour before the reproduction of the model.
- the control animals were injected with the appropriate solvent.
- the results are presented in tables 3 and 4.
- Compound 1a was found to have high analgesic activity in the hot plate test.
