We designed 1-alkyloxygenipins with the aim of improving the stability of genipins based on the structural and electronic properties of genipins, and prepared 1-alkyloxygenipins and examined their neuritogenic activities in PC12h cells. All genipin-derivatives exhibited electronic properties similar to those of genipin and induced significant neurite outgrowth. These compounds will be classified as nitric oxide synthase (NOS) activators (neuritogenic active compounds) since their lowest unoccupied molecular orbital (LUMO)-energies are similar to that of tetrahydrobiopterin (H4B). (1R)-isoPropyloxygenipin showed activity comparable to that of genipin, and unlike the parent compound genipin, it was found to be physiologically stable in rat liver homogenate.
我们根据基因素的结构和电子特性设计了1-烷氧基基因素,旨在提高基因素的稳定性,并制备了1-烷氧基基因素,研究了它们在PC12h细胞中的致神经活性。所有基因素衍生物都表现出与基因素相似的电子特性,并能诱导神经元显著生长。这些化合物将被归类为一氧化氮合酶(NOS)激活剂(致神经活性化合物),因为它们的最低未占分子轨道(LUMO)能量与四氢生物蝶呤(H4B)相似。(1R)-isoPropyloxygenipin 的活性与基因素相当,而且与母体化合物基因素不同,它在大鼠肝匀浆中具有生理稳定性。
