Six coumarin-caged compounds of 1-naphthaleneacetic acid (NAA) comprising different substituents on the coumarin moiety were synthesized and evaluated for their photophysical and chemical properties as light-responsive controlled-release plant root stimulators. The 1H NMR and HPLC techniques were used to verify the release of NAA from the caged compounds. After irradiation at 365 nm, the caged compounds
合成了在香豆素部分上包含不同取代基的六种香豆素笼罩的1-萘乙酸(NAA)化合物,并作为光响应性控释植物根部刺激剂对其光物理和化学性质进行了评估。的1项H NMR和HPLC技术被用来从笼化合物验证NAA的释放。在365 nm照射后,笼中化合物在6.7天的t 1/2处显示最快的释放速率,在73.7天的t 1/2上显示最慢的释放速率。笼状化合物,浓度高(10 –5和10 –6M)显着刺激次生根发芽,而相同水平的游离NAA是有毒的并导致次生根发芽的抑制。评估了笼状化合物对成纤维细胞和维罗细胞的细胞毒性,结果表明,在10 –5 –10 –6 M时,笼状化合物对细胞没有明显的细胞毒性。因此,在这项研究中,NAA的笼状化合物可以作为有效的农药有效利用。
