Abstract
Invenţia se referă la substanţele heterociclice, în particular, la derivaţii oxadiazolilalchilpurinei cu formula generală:c) n=3 sau 4, R1 reprezintă (C2H5)2 .N--(CH2)2.HCl;d) n=1 - 4, R1 reprezintă CH3,care manifestă activitate antitusivă, ceea ce poate fi utilizat în medicină.Scopul este obţinerea substanţelor noi mai active din clasa dată. Sinteza, de exemplu, a 3,7-dihidro-3-metil -7- [(5- clormetil - 1,2,4 - oxadiazol -3-il) metil]- 1H-purină -2,6-dionului are loc prin acilarea a 2 -[3-metilxantin -7-il] acetamidooximului cu cloracetilcloridă în prezenţa Na2CO3 în mediul acetonei anhidre. Compuşii noi cu toxicitatea DL50 =250 -700 mg/kg au o mai mare activitate antitusivă în doze mai mici, în comparaţie cu compuşii cunoscuţi, şi ei nu exercită acţiune de blocare a respiraţiei, dar considerabil o ameliorează.Revendicări:1.
