Azaindole N-methyl hydroxamic acids as HIV-1 integrase inhibitors-II. The impact of physicochemical properties on ADME and PK. | LitMetric

AI Article Synopsis

  • * Researchers have developed azaindole hydroxamic acids that effectively inhibit the HIV-1 integrase enzyme, while some compounds show improved stability and longer-lasting effects in the body.
  • * Modifying the chemical structure of these inhibitors has led to better pharmacokinetic profiles, including moderate oral bioavailability and manageable half-lives, without significantly compromising their effectiveness against the virus.

Article Abstract

HIV-1 integrase is one of three enzymes encoded by the HIV genome and is essential for viral replication, and HIV-1 IN inhibitors have emerged as a new promising class of therapeutics. Recently, we reported the discovery of azaindole hydroxamic acids that were potent inhibitors of the HIV-1 IN enzyme. N-Methyl hydroxamic acids were stable against oxidative metabolism, however were cleared rapidly through phase 2 glucuronidation pathways. We were able to introduce polar groups at the β-position of the azaindole core thereby altering physical properties by lowering calculated log D values (c Log D) which resulted in attenuated clearance rates in human hepatocytes. Pharmacokinetic data in dog for representative compounds demonstrated moderate oral bioavailability and reasonable half-lives. These ends were accomplished without a large negative impact on enzymatic and antiviral activity, thus suggesting opportunities to alter clearance parameters in future series.
