Pharmacological action:
Antiviral mean, synthetic carbocyclic analogue of nukleozidov. Into a cage abakavir transforms with participation of cellular enzymes in active metabolit karbovir trifosfat. Karbovir trifosfat is the analogue of deoksiguanozin-5"-òðèôîñôàòà (dGTF). Karbovir trifosfat ingibiruet activity of HIV-1 of reverse transkriptazy, that is conditioned a competition with natural substratom of dGTF and violation of his building in viral DNA. Loss 3"-HE groups in the built-in analogue of nukleozida are prevented by forming of 5"- and 3"-fosfornoefirnykh connections, necessary for the elongacii chainlet of DNA. As a result of it growth of viral DNA is halted.
