Several tropolone derivatives (4-7) were designed as novel retinoids on the assumption that the tropolone ring may mimic the benzoic acid moiety in retinoid structures, such as Am80 (2). Among the synthesized compounds, 5-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)ethynyl]tropolone (7a) showed moderate potency as a differentiation-inducer of HL-60 cells. The activities of the tropolones were
假定托酚酮环可模仿类维生素A结构中的苯甲酸部分,例如Am80(2),则将几种托酚酮衍生物(4-7)设计为新型维甲酸。在合成的化合物中,5- [2-(5,6,7,8-四氢-5,5,8,8-四甲基-2-萘基)乙炔基] tropolone(7a)具有中等强度,可作为诱导分化的化合物HL-60细胞。在RXR激动剂(类维生素A增效剂)HX630的存在下,对营养素的活性大大增强。
