Novel HIV integrase inhibitors with anti-HIV activity: insights into integrase inhibition from docking studies.
The mechanism of integrase is generally accepted to be dependant on the presence of two divalent metal ions in the active site. However, the only available crystal structures of HIV-1 integrase contain either one or no metal ions, hampering structure-based design studies of integrase inhibitors. For this reason, a two-metal ion model of integrase was constructed. This model was used for computa...
متن کاملResistance to Integrase Inhibitors
Integrase (IN) is a clinically validated target for the treatment of human immunodeficiency virus infections and raltegravir exhibits remarkable clinical activity. The next most advanced IN inhibitor is elvitegravir. However, mutant viruses lead to treatment failure and mutations within the IN coding sequence appear to confer cross-resistance. The characterization of those mutations is critical...
متن کاملPatterns of resistance development with integrase inhibitors in HIV
Raltegravir, the only integrase (IN) inhibitor approved for use in HIV therapy, has recently been licensed. Raltegravir inhibits HIV-1 replication by blocking the IN strand transfer reaction. More than 30 mutations have been associated with resistance to raltegravir and other IN strand transfer inhibitors (INSTIs). The majority of the mutations are located in the vicinity of the IN active site ...
متن کاملResistance to HIV Integrase Inhibitors: About R263K and E157Q Mutations
The use of integrase inhibitors (INI) is increasing in antiretroviral therapies (ART) and INI are not all equal regarding genetic barrier to resistance. The aim of this manuscript was to review main in vivo and in vitro knowledge about two particular integrase resistance-associated mutations: R263K and E157Q. The R263K mutation was the first mutation rarely found selected at time of virological...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
