    Pyridoxal isonicotinoyl hydrazone (PIH) and its analogs as protectants against anthracycline-induced cardiotoxicity

  • Original language description

    This study was aimed to assess the cardioprotective effects of aroylhydrazone iron (FE) chelators: pyridoxal isonicotinoyl hydrazone (PIH) and its two analogs: salicyladehyde isonicotinoyl hydrazone (SIH) and pyridoxal o-chlorbenzoyl hydrazone (o-108). Chronic co-administrations of PIH (25 mg/kg, i.p.), SIH hydrochloride [1 mg/kg, iv] as well as o-108 (10 mg/kg, i.p.), fully prevented premature deaths and most of the DAU-induced functional impairments were significantly suppressed. However, when 2- to 2.5-fold higher doses of the chelators were used, they led to rather paradoxical and mostly negative results regarding both cardioprotection and overall mortality.

    Pyridoxal isonicotinoyl hydrazon (PIH) a jeho analoga jako kardioprotektiva proti antracyklinem-indukované kardiotoxicitě

  • Czech description

    Tato studie byla zaměřena na studium a porovnání kardioprotektivních účinků arolyhydrazonových chelátorů železa pyridoxal isonicotinoyl hydrazonu (PIH) a dvou jeho analogů - salicyladehyd isonicotinoyl hydrazonu (SIH) a pyridoxal o-chlorbenzoyl hydrazonu(o-108). Opakované společné podání PIH (25 mg/kg, i.p.), SIH hydrochloride [1 mg/kg, iv] as well as o-108 (10 mg/kg, i.p.) spolu s daunorubicinem bylo schopno plně zabránit předčasnému úhynu zvířat a většina funkčních abnormalit navozených cytostatikembyla signifikantně potlačena. Nicméně, 2- 2,5 násobné zvýšení dávek chelátoru vedlo k převážně negativním výsledkům jak z hlediska kardioprotekce, tak s ohledem na celkovou mortalitu.
