  Design and synthesis of novel chromenone derivatives as interleukin-5 inhibitors

  摘要：

  A novel series of chromenone analogs were synthesized and evaluated for their inhibitory activity against interleukin-5. Among them 5-(cyclohexylmethoxy)-3-[3-hydroxy-3-(4-hydroxyphenyl)propyl]-4H-chromen-4-one (9b, 94% inhibition at 30 mu M, IC50 = 4.0 mu M) and 5-(cyclohexylmethoxy)-3-[3-hydroxy-3-(4-methoxyphenyl)propyl]-4H-chromen-4-one (9c, 94% inhibition at 30 mu M, IC50 = 6.5 mu M) showed the most potent activity. According to the SAR studies introduction of propanone unit in between chromenone and ring B as in 5-(cyclohexylmethoxy)-3-[3-(4-phenyl)-3-oxopropyl]-4H-chromen-4-ones (8) moderately increased the activity. However, the reduction of these propanones 8 to propanols 9 remarkably enhanced the activity. A small substituent at position 4 of ring B in 9, especially with hydrogen bonding capability, provides favorable contribution. Disappearance of IL-5 inhibitory activity upon saturation of chroman-4-one of 9 to chroman-4-ones 10 proves the critical importance of planar chromen-4-one unit of this scaffold in the IL-5 inhibition.
