Farmacinės kompozicijos, į kurias įeina terapiškai efektyvus (I) formulės junginio kiekis, gali būti naudojamos žmonių hiperglikemijos gydymuij tokio gydymo atveju (I) formulės junginio kiekis, suvartojamas per dieną, yra 50-3000 mg ribose. Tinkamiausias vartojimo būdas yra per burną.
Junginiai, kurių formulė (III), gali būti gaunami, veikiant (IV) formulės tiokarbamidus:
R (IV) kur Rg yra vandenilis, fluoras, chloras, metilas arba metoksi grupė, natrio chloridu, esant bazei, tokiai kaip natrio karbonatas ir vario katalizatoriui, tokiam kaip vario(I) ir vario(II) chloridų mišiniui.
(IV) formulės tiokarbamidus galina gauti, reaguojant amo niakui su izotiocianatu, kurio formulė (V):
R (V) (V) formulės junginius galima gauti, veikiant (VI) formų lės junginius*.
tiofosgenu skystoje reakcijos terpėje, tokioje kaip dioksanas. Junginių, kurių formulė (I), duotų tolimesniuose pavyzdžiuose, hipoglikeminis aktyvumas buvo patvirtintas tokiu testu. Žiurkės, sveriančios po 150-200 g, fiksuojamos 18 valandų, tada po oda įleidžiama gliukozės (800 mg / 4 ml /kg), o po to per gerklę duodama tiriamųjų junginių dozė (x mg / 4 arba 5 ml 2 %-nio agaro / kg). Po 2 ir 4 valandų paimama kraujo iš akiduobės, ir gliukozės kiekis plazmoje įvertinamas Bekmano gliukozės analizatoriumi, panaudojant specifinį gliukozės oksidinimo metodą (Kadish A.H., Little R.L. and Sternberg J.C.,
Clin. Chem., 14, 116 (1968)). Po to išskaičiuojamas gliukozės kiekio plazmoje sumažėjimas procentais, lyginant su kontroliniais gyvuliukais, kurie negavo tiriamojo junginio, o gavo tik 2 %-nį agaro homogenatą. Laikoma, kad junginiai šiame teste pasižymi hipoglikeminiu aktyvumu, jeigu jie sukėlė 15 arba daugiau % gliukozės kiekio plazmoje sumažėjimą, esant bet kokioms x reikšmėms iki 200 tiek po 2-jų, tiek ir po 4-rių valandų. Rezultatai, gauti aukščiau aprašytuose testuose esant bet kokioms x reikšmėms, įvertinami ir kiekvieno junginio hipoglikeminis aktyvumas klasifikuojamas pagal tokią skalę. Jeigu konkrečiam x buvo atlikta daugiau negu viena bandymų serija junginių aktyvumo klasifikacijai imamas vidutinis sumažėjimo procentas.
Junginių, aprašytų toliau duodamuose pavyzdžiuose, aktyvu duodamas 1-je lentelėje.
