Pharmakologipharmacology
Aktiviteten af de her omhandlede forbindelser blev undersøgt ved forskellige forsøg. Tre af disse beskrives nærmere i det følgende.The activity of the compounds of this invention was investigated in various experiments. Three of these are described in more detail below.
20 I - Lethalitet_fremkaldt_af_Yohimbin_HCl_hos_mus20 I - Lethality_called_of_Yohimbin_HCl_hos_mus
Denne prøve blev gennemført på grupper af 10 hanmus, CD-I (Charles River). Hver af de behandlede mus modtog 0,25 ml/20 g af en suspension indeholdende den afprøvede dosis af en forbindelse. En time efter indgiften fik 25 musene en subcutan injektion af 30 mg/kg Yohimbin HC1.This test was conducted on groups of 10 male mice, CD-I (Charles River). Each of the treated mice received 0.25 ml / 20 g of a suspension containing the tested dose of a compound. One hour after administration, the 25 mice received a subcutaneous injection of 30 mg / kg of Yohimbin HCl.
Procenten af dødsfald (L) blev bestemt 18 timer efter denne injektion. For hver afprøvet forbindelse anvendtes en Yohimbin HCl-kontrolgruppe. Resultaterne er sammenstillet i tabel I.The percentage of deaths (L) was determined 18 hours after this injection. For each compound tested, a Yohimbine HCl control group was used. The results are summarized in Table I.

14 II - Antagonisme_med_catalepsi_induceret_med_halogeridol14 II - Antagonism_with_catalepsia_induced_with_halogeridol
Dette forsøg blev gennemført under sammenligning med to referenceforbindelser, imipramin og 5-hydroxytrytophan, på Wistar-hanrotter på 140/170 g i grupper på seks rot-5 ter i hver gruppe.This experiment was performed in comparison with two reference compounds, imipramine and 5-hydroxytryptophan, on male Wistar rats of 140/170 g in groups of six rats in each group.
IP-indgift af 5 mg/kg haloperidol medfører catalepsi. Yderligere oral indgift af de afprøvede forbindelser 1 time efter indsprøjtning med haloperidol modvirker catalepsi.IP administration of 5 mg / kg haloperidol results in catalepsy. Further oral administration of the tested compounds 1 hour after injection with haloperidol counteracts catalepsy.
10 Man afprøvede otte af de omhandlede forbindelser i forskellige doser (en gruppe for hver dosering med hver forbindelse). Virkningen på catalepsi blev bestemt 1, 2, 3, 4 og 5 timer efter indgiften af den afprøvede forbindelse, idet man anbragte rotternes bagpoter på en me-15 talstang 10 cm over bordniveauet (forsøget blev gennemført i et støjfrit rum ved 22°c). Hvis rotten var i stand til at blive stående i 20 sekunder, blev der tildelt 1 point, for 20 sekunder blev der tildelt 2 point osv. op til 5 point for 100 sekunder. Gennemsnitsværdi-20 erne blev, med den tilsvarende antagonisme målt i procent, beregnet for hver enkelt gruppe.Eight of the compounds in question were tested in different doses (one group for each dose with each compound). The effect on catalepsy was determined 1, 2, 3, 4 and 5 hours after administration of the tested compound, placing the rats' hind legs on a metal rod 10 cm above the table level (the experiment was conducted in a noise-free room at 22 ° C). . If the rat was able to stand for 20 seconds, 1 point was awarded, for 20 seconds, 2 points, etc., were awarded up to 5 points for 100 seconds. The average values, with the corresponding antagonism measured as a percentage, were calculated for each group.
Resultaterne er sammenstillet i tabel II.The results are summarized in Table II.
III - Fprtyivlelsesfgrsøg på musIII - Fertilization tests on mice
Dette forsøg blev gennemført på hanmus, CD-I (Charles 25 River) i grupper med 10 mus i hver gruppe under anvendelse af Maprotiline som sammenligningsforbindelse. En time før forsøget fik musene en dosering på 0,4 ml/20 kg af en suspension svarende til en passende dosis i mg/kg af de afprøvede forbindelser.This experiment was performed on male mice, CD-I (Charles 25 River) in groups of 10 mice in each group using Maprotiline as a comparison compound. One hour before the experiment, the mice received a dosage of 0.4 ml / 20 kg of a suspension corresponding to a suitable dose in mg / kg of the tested compounds.
30 Musene blev anbragt i plexiglascylindre (højde 2.5 cm, diameter 10 cm) indeholdende vand ved 22°C. ImmobiliThe mice were placed in plexiglass cylinders (height 2.5 cm, diameter 10 cm) containing water at 22 ° C. immobilisation
DK 157871 BDK 157871 B
15 tetsperioden blev målt mellem det andet og det sjette minut. Der anvendtes en kontrolgruppe for hver forbindelse og en kontrolgruppe pr. afprøvet dosis.The time period was measured between the second and sixth minutes. One control group was used for each compound and one control group per tested dose.
Resultaterne er sammenstillet i tabel III, hvor A bety-5 der den gennemsnitlige immobilitetsperiode, og B betyder den procentiske variation i forhold til kontrolgruppen.The results are summarized in Table III, where A means the mean immobility period and B means the percentage variation relative to the control group.
Præparatformer - posologiForms of Preparation - Posology
Mere sædvanligt anvendte former inden for human-terapien 10 er for eksempel tabletter eller gelatinekapsler indeholdende 0,1 g aktiv forbindelse pr. doseringsenhed eller ampuller indeholdende samme mængde på opløst eller suspenderet form til IV-injektion.More commonly used forms in human therapy 10 are, for example, tablets or gelatin capsules containing 0.1 g of active compound per day. dosage unit or ampoules containing the same amount of dissolved or suspended form for IV injection.
Sædvanlige doseringer er op til 0,5 g/dag i mindst to 15 uger for orale former eller op til 0,2 g/dag i mindst en uge for injektionspræparater, idet denne behandling opfølges med oral indgift i mindst 1 uge.Usual dosages are up to 0.5 g / day for at least two 15 weeks for oral forms or up to 0.2 g / day for at least one week for injections, following this treatment with oral administration for at least 1 week.
