(E)-4-[3-[3,5-bis(trimethylsilyl)phenyl]-3-oxo-1-propenyl]benzoic acid (22, Ch55S) and (E)-4-[3-[3,5-bis(trimethylgermyl)phenyl]-3-oxo-1- propenyl]benzoic acid (35, Ch55G) are more active than retinoic acid by 1 order of magnitude. However, in the para-substituted chalcone derivatives, the replacement of a tert-butyl group (49, Ch40) with a trimethylsilyl (27, Ch40S) or a trimethylgermyl (30, Ch40G) group
基于对人早幼粒细胞白血病细胞HL-60的分化诱导活性,讨论了含有三甲基甲硅烷基或三甲基甲锗烷基的视黄苯甲酸的类视黄醇活性。在通式2的间位具有三甲基甲硅烷基或三甲基锗基的化合物比具有间叔丁基的相应视黄基苯甲酸具有更强的活性。具有两个间三甲基甲硅烷基或-三甲基锗烷基的化合物也具有很强的活性,并且(E)-4- [3- [3,5-双(三甲基硅烷基)苯基] -3-氧代-1-丙烯基]苯甲酸(22, Ch55S)和(E)-4- [3- [3,5-双(三甲基锗烷基)苯基] -3-氧代-1-丙烯基]苯甲酸(35,Ch55G)比视黄酸的活性高1个数量级。但是,在对位取代的查耳酮衍生物中,叔丁基的取代(49,
