    • The present invention relates to a novel hydroxyethylaminomethylchromenone derivative, a manufacturing method thereof, or a pharmaceutical composition including the hydroxyethylaminomethylchromenone derivative for preventing or treating allergic diseases. Since the hydroxyethylaminomethylchromenone derivative is low-molecular, non-peptide-based material, the derivative has no non-specific reaction for proteins unlike existing treating agents known for allergic diseases. In addition, the hydroxyethylaminomethylchromenone derivative of the present invention is an amine-form compound, and thereby, remarkably increasing water solubility compared to the existing hydroxyethylaminomethylchromenone derivatives manufactured, as well as having higher effects of inhibiting interleukin-5 activities due to difference in chemical structures, such that the compound of the present invention can be effectively used as an inhibitor for allergic diseases. Furthermore, since the existing hydroxyethylaminomethylchromenone derivatives have a chiral center, it produces inconvenience as it requires to check whether the an isomer exists or not. However, the present invention solves the inconvenience so as to have an advantage of being capable of easily manufacturing a compound. [Reference numerals] (AA,CC) Compound 3d; (BB,DD) Compound 4i
    • 本发明涉及一种新型羟乙基氨基甲基色精酮衍生物,其制备方法或包含用于预防或治疗过敏性疾病的羟乙基氨基甲基异色酮衍生物的药物组合物。 由于羟乙基氨基甲基色精酮衍生物是低分子非肽类材料,所以与现有的过敏性疾病已知的治疗剂不同,该衍生物对蛋白质没有非特异性反应。 此外,本发明的羟乙基氨基甲基色精酮衍生物是胺型化合物,因此与现有的制造的羟乙基氨基甲基异色酮衍生物相比,水溶性显着提高,并且由于化学结构的差异而具有较高的抑制白细胞介素-5活性的作用 ,使得本发明的化合物可以有效地用作过敏性疾病的抑制剂。 此外,由于现有的羟乙基氨基甲基色烯酮衍生物具有手性中心,因此需要检查异构体是否存在而产生不便。 然而,本发明解决了不便之处,从而具有能够容易地制造化合物的优点。 (AA,CC)化合物3d; (BB,DD)化合物4i
