New boron-containing polyamine have been synthesized: (aminoalkylamine)-N-(aminoalkyl)azanonaborane(11) derivatives [H(2)N(CH(2))(n)H(2)NB(8)H(11)NH(CH(2))(n)NH(2)], where n = 4-6 and 12, and [H(2)N(CH(2))(3)H(2)NB(8)H(11)NH(CH(2))(4)NH(2)]. (4-Aminobutylamine)-N-(4-aminobutyl)azanonaborane and (3-aminopropylamine)-N-(4-aminobutyl)azanonaborane were less toxic in vitro (LD(50) of approximately 700 and approximately 1100 microM, respectively) than spermine, while (4-aminobutylamine)-N-isopropylazanonaborane with its hydrophobic isopropyl group and those with n = 5, 6, and 12 were already toxic under similar conditions (LD(50) << 500 microM). These compounds may be useful as delivery agents for boron neutron capture therapy.
(氨基烷基胺)-N-(氨基烷基)氮杂壬硼烷(11)衍生物[H₂N(CH₂)ₙH₂NB₈H₁₁NH(CH₂)ₙNH₂],其中n = 4 - 6和12,以及[H₂N(CH₂)₃H₂NB₈H₁₁NH(CH₂)₄NH₂]。(4-氨基丁胺)-N-(4-氨基丁基)氮杂壬硼烷和(3-氨基丙胺)-N-(4-氨基丁基)氮杂壬硼烷在体外的毒性(半数致死量分别约为700和约1100微摩尔)比精胺小,而具有疏水性异丙基的(4-氨基丁胺)-N-异丙基氮杂壬硼烷以及n = 5、6和12的那些化合物在类似条件下已具有毒性(半数致死量 << 500微摩尔)。这些化合物可用作硼中子俘获疗法的递送剂。
