Seuraavat esimerkit havainnollistavat keksintöä lähemmin:The following examples further illustrate the invention:
Esimerkki 1: 2-isopropyyliamino 5-hydroksipyrimidiini 1 litran reaktoriin kaadettiin 80 ml vettä, 3 g natriumhydroksidia, hieman kuparijauhetta ja 4,3 g (0,02 moolia) 2-isopropyyliamino-5-bromi-pyrimidiiniä; reaktioseos pidettiin lämpötilassa 130 - 135°C 1 tunti, jolloin samalla sekoitettiin, ja sen jälkeen noin 12 tuntia 130 - 140°C:ssa, jolloin myös sekoitettiin.Example 1: 2-Isopropylamino 5-hydroxypyrimidine In a 1 liter reactor were poured 80 ml of water, 3 g of sodium hydroxide, a little copper powder and 4.3 g (0.02 mol) of 2-isopropylamino-5-bromopyrimidine; the reaction mixture was kept at 130-135 ° C for 1 hour while stirring, and then at 130-140 ° C for about 12 hours while stirring.
Kuparin suodattamisen jälkeen reaktioseos uutettiin kaksi kertaa kloroformilla. Yhdistetyt uutteet tehtiin happameksi etikkahapolla pH-arvoon 6,5 - 7,0. Sen jälkeen liuos kyllästettiin natriumklori-dilla, jolloin tuote saostui. Tuote otettiin talteen ja pestiin vedellä ja sen jälkeen pentaanilla. Tuote otettiin dietyylieette-riin ja käsiteltiin hiilimustalla. Liuos väkevöitiin, jolloin tuote saostui. Tuote otettiin talteen ja kiteytettiin uudelleen vedestä tai isopropyyliasetaatista. Kiteet kuivattiin, jolloin saatiin 2,45 g (saanto 80 %) 2-isopropyyliamino-5-hydroksi-pyrimidiiniä. Alkuaineanalyysi vastasi odotettua empiiristä kaavaa C^H^jN^O.After filtration of copper, the reaction mixture was extracted twice with chloroform. The combined extracts were acidified with acetic acid to pH 6.5-7.0. The solution was then saturated with sodium chloride, whereupon the product precipitated. The product was collected and washed with water and then with pentane. The product was taken up in diethyl ether and treated with carbon black. The solution was concentrated to precipitate the product. The product was recovered and recrystallized from water or isopropyl acetate. The crystals were dried to give 2.45 g (80% yield) of 2-isopropylamino-5-hydroxypyrimidine. Elemental analysis corresponded to the expected empirical formula C ^ H ^ jN ^ O.
Lähtäaineena käytetty 2-isopropyyliamino-5-bromi-pyrimidiini saadaan helposti saattamalla 2-isopropyyliamino-pyrimidiini ja N-bromi-sukkinimidi reagoimaan keskenään stökiömetrisissä suhteissa etikkahapon läsnäollessa (saanto 84 %).The starting 2-isopropylamino-5-bromopyrimidine is easily obtained by reacting 2-isopropylamino-pyrimidine and N-bromo-succinimide in stoichiometric proportions in the presence of acetic acid (yield 84%).

FarmakologiaPharmacology
Keksinnön mukaisen yhdisteen farmakologinen aktiivisuus on tutkittu vertailukokeella, jossa seurattiin täysikasvuisen urosrotan (Wistar) lonkkahermon regeneroitumista.The pharmacological activity of the compound of the invention has been studied in a comparative experiment in which the regeneration of the sciatic nerve of an adult male rat (Wistar) was monitored.

Rottien lonkkahermoa viotettiin kohdistamalla hermoon 20 minuuttia lämpöääntä -20°C:ssa. Sen jälkeen rottia hoidettiin määrätty aika i.p. vertailutuotteella tai keksinnön mukaisilla yhdisteillä. Hoidon lopussa rotat tapettiin, lonkkahermot erotettiin ja niihin kytkettiin 70 ohuen yhdensuuntaisen platinalangan (etäisyys 1 mm) joukko. Platinalankojen avulla seurattiin viotetun kohdan yläpuolelle syötettyä sähkösignaalia: Regeneroitunut pituus saadaan etäisimmästä langasta, josta signaali voidaan havaita.The sciatic nerve of rats was damaged by subjecting the nerve to heat for 20 minutes at -20 ° C. The rats were then treated for a specified time i.p. reference product or compounds of the invention. At the end of the treatment, the rats were sacrificed, the sciatic nerves were separated and connected to a set of 70 thin parallel platinum wires (distance 1 mm). Platinum wires were used to monitor the electrical signal applied above the damaged point: The regenerated length is obtained from the farthest wire from which the signal can be detected.
Kutakin testattua seosta ja kutakin hoitoaikaa kohti käytettiin 8 rotan ryhmää.For each mixture tested and each treatment time, 8 groups of rats were used.
Neljä seosta testattiin i.p.: Esimerkin 1 yhdiste, esimerkin 2 yhdiste, esimerkin 3 yhdiste, kaikki i.p. annoksella 10 mg/kg, ja vertailuyh-disteenä vitamiinien Bl (500 mg/kg), B6 (500 mg/kg) ja B12 ( 5 mg/kg) seos, jonka ammattimiehet tietävät olevan tehokkaimman seoksen tällä alalla. Kontrolleja ei hoidettu lainkaan. Kutakin kestoaikaa kohti &, 11, 14, 17 ja 21 päivää) käytettiin viisi 8 eläimen ryhmää sekä kontrolleille, yhdisteille 1, 2, 3 että vertailuseokselle.Four mixtures were tested i.p .: Example 1 compound, Example 2 compound, Example 3 compound, all i.p. at a dose of 10 mg / kg, and as a reference compound a mixture of vitamins B1 (500 mg / kg), B6 (500 mg / kg) and B12 (5 mg / kg), which are known to those skilled in the art to be the most effective mixture in this field. Controls were not performed at all. For each duration & (11, 14, 17, and 21 days), five groups of 8 animals were used for both controls, compounds 1, 2, 3, and control mixture.
Seuraavaan taulukkoon on koottu tämän kokeen tulokset ja kontrolli-eläimillä saadut arvot. Regeneroituneiden hermojen pituudet on annettu mm:ssä vastaavan päivän pystyrivissä jokaisen ryhmän kaikilla eläimillä mitattujen pituuksien keskiarvona. Kun mitään lukua ei ole esitetty (17 ja 21 päivää), tämä tarkoittaa, että regeneroitunut pituus oli suurempi kuin otetun näytteen pituus.The following table summarizes the results of this experiment and the values obtained with control animals. The lengths of the regenerated nerves are given in mm in the vertical row of the corresponding day as the average of the lengths measured in all animals in each group. When no figure is shown (17 and 21 days), this means that the regenerated length was greater than the length of the sample taken.
