chemistry offers the potential to tune the effects of biologically active organic molecules. Subtle changes in the molecular backbone caused by the exchange of a carbon atom for a silicon atom (sila-substitution) can significantly alter the biological properties. In this study, the biological effects of a two-fold sila-substitution in the synthetic retinoids EC23 (4-(5,5,8,8-tetramethyl-5,6,7,8-tetr
硅化学为调节生物活性有机分子的作用提供了潜力。由碳原子交换为硅原子引起的分子主链的细微变化(硅原子取代)可以显着改变生物学特性。在这项研究中,在合成类视黄醇EC23中,双倍sila取代的生物学效应(4-(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基乙炔基)苯甲酸(4a))和TTNN(6-(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基)-2-萘甲酸(7a))及其对应的类似物用茚满代替1,2,3,4-四氢萘骨架(化合物5a和8a)进行了研究。在4a,5a,7a和8a中进行两次C / Si交换会导致硅类似物disila-EC23(4b),5b,disila-TTNN(7b)和8b,其中包含1,2,3,4-四氢-1,4-二硅萘(4b,7b)或1,3-二硅氢化茚骨架(5b,8b)。交换SiCH 2 Si部分对于SiOSi片段,图5b得到二硅氧烷6(2-oxa-1,3-二硅氢化茚骨
