Abacavir sulfate

Abacavir sulfate is white to off-white crystalline powder and the solubility is pH dependent with minimal solubility at basic pH and increased solubility at acid. This active substance is slightly soluble in diethyl ether and ethanol. Abacavir exhibits stereoisomerism due to the presence of two chiral centres (1S,4R absolute configuration).

개요Abacavir sulfate was first launched as Ziagen in the US for the treatment of human immunodeficiency virus (HIV) infection, in combination with other antiretroviral drugs. Abacavir is a carbocyclic nucleoside reverse transcriptase inhibitor (nRTI); it is one of the most potent anti-HIV agents to date. In vitro, Abacavir is a potent and selective inhibitor of HIV-1 and HIV-2 replication. Resistance to Abacavir develops more slowly than for other anti-HIV agents. Abacavir is highly synergistic with protease inhibitors such as Amprenavir. In clinical trials for HIV infections in adults, it produced durable suppression in viral load. Combinations with different protease inhibitors such as Nelfinavir, Saquinavir or Indinavir markedly reduced plasma viral load to undetectable levels for at least 48 weeks, and significantly raised CD4+ cell counts in adults with HIV infection, especially nRTI-naive patients. Abacavir has a good oral availability and its penetration into CSF is much more significant than for other anti-HIV drugs. The two major metabolites identified in humans were the 5'-carboxylate and the 5'-glucuronide, mainly excreted via the renal route.

용도Abacavir sulfate is a nucleoside reverse transcriptase inhibitor (NRTI) used for the treatment of HIV-1 infection and anti-AIDS drug. It has been used in the cytotoxicity to test its tumour promoting activity U937 cells.

일반 설명Abacavir sulfate belongs to the class of human immunodeficiency virus (HIV) medicines called nucleoside reverse transcriptase inhibitors, with antiretroviral activity against HIV.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
