  Prodrugs of neuron-selective monoamine oxidase inhibitors: amino acid derivatives of 1-(4-aminophenyl)-2-aminopropanes

  摘要：

  Six amino acid derivatives of 1-(4-aminophenyl)-2-aminopropanes and their parent amines were synthezised and tested for their potency and selectivity in inhibiting monoamine oxidase (MAO) in vitro and in vivo. The amino acid derivatives were 300-1000 times less potent than the parent amines in inhibiting the MAO-A activity in a rat brain mitochondrial preparation in vitro. All compounds, except the (R)-valinamide derivative (22), were potent inhibitors of MAO in the rat brain in vivo and were, like the parent amines markedly more potent within the monoaminergic neurons than in other neurons. The glycinamide derivative 7 showed the largest difference between intra- and extra-neuronal inhibition in serotonergic neurons. The time course of the inhibitory effect of 7 in vivo showed that it is a reversible inhibitor with a long duration. (C) Elsevier, Paris.

  We report sodium trihydroxyaryl borates as the first robust tetracoordinate organoboron catalysts for reductive functionalization of CO2. These catalysts, easily synthesized from condensing boronic acids with metal hydroxides, activate main group element–hydrogen (E–H) bonds efficiently. In contrast to BX3 type boranes, boronic acids and metal-BAr4 salts, under transition metal-free conditions, sodium

  我们报告三羟基芳基硼酸钠作为第一个坚固的四配位有机硼催化剂，用于CO 2的还原功能化。这些催化剂很容易从硼酸与金属氢氧化物的缩合反应中合成，可以有效地活化主族元素氢键。与BX 3型硼烷，硼酸和金属-BAr 4盐相比，在无过渡金属的条件下，三羟基芳基硼酸钠对各种胺（包括带有官能团的胺）表现出较高的还原性N-甲酰化反应性（106例）例如酯，烯烃，羟基，氰基，硝基，卤素，MeS–，醚基等。催化具有挑战性的吡啶胺的甲酰化反应的性能过高，为使用传统的甲酰化试剂提供了一种有前途的替代方法。机理研究支持将静电相互作用作为Si / B–H活化的关键，从而使碱金属硼酸盐成为用于CO 2加氢硼化，加氢硅烷化和还原甲酰化/甲基化的通用催化剂。
