According to the invention, there are provided novel amide derivatives and 5-lipoxygenase inhibitors containing the same as an effective ingredient.
The above-mentioned compounds of the invention have been demonstrated to possess 5-lipoxygenase-inhibiting activities. These compounds can inhibit the production of leucotrienes such as LTC4 and LTD4 which are allergy-inducing factors by inhibiting the activity of 5-lipoxygenase. Accordingly, the amide derivatives can be used as 5-lipoxygenase inhibitors effective for allergic asthma, allergic rhinitis and the like.
An isoxazole derivative represented by general formula (1), a salt thereof, a process for the production thereof, an inhibitor for lipoxygenase and cyclooxygenase containing an effective dose of the derivative and a pharmaceutical carrier, and a method of inhibiting lipoxygenase and cyclooxygenase by administering the derivative to a patient. In formula (1) R and R' may be the same or different from each other and each represents hydrogen, lower alkyl, lower alkoxy or halogen; m represents 0 to 5; A represents -NH-, -O- or a direct bond; B represents -C(=Z)-NH-, -C(=Z)-(CH=CH)l- or -CH=CH-, wherein Z represents oxygen or sulfur, and 1 represents 0 to 2; X represents nitrogen or carbon; n represents 0 to 3; and Y represents hydroxy, lower alkoxy, lower alkoxycarbonyloxy, etc.; provided that m represents 1 to 5 when A represents -NH-.
通式(1)代表的异噁唑衍生物、其盐、其生产工艺、含有有效剂量该衍生物和药物载体的脂氧合酶和环氧合酶抑制剂,以及通过向患者施用该衍生物来抑制脂氧合酶和环氧合酶的方法。在式(1)中,R和R'可以彼此相同或不同,各自代表氢、低级烷基、低级烷氧基或卤素;m代表0至5;A代表-NH-、-O-或直接键;B代表-C(=Z)-NH-、-C(=Z)-(CH=CH)l-或-CH=CH-,其中 Z 代表氧或硫,1 代表 0 至 2;X 代表氮或碳;n 代表 0 至 3;Y 代表羟基、低级烷氧基、低级烷氧基羰氧基等。但当 A 代表-NH-时,m 代表 1 至 5。

New sulfurated derivatives of cinnamic acids and rosmaricine as inhibitors of STAT3 and NF-κB transcription factors
able to inhibit the NF-κB transcriptional activity in HCT-116 cell line and inhibited HCT-116 cell proliferation in vitro with IC50 in micromolar range, thus suggesting a potentialanticancer activity. Taken together, our study described the identification of new derivatives with dual STAT3/NF-κB inhibitory activity, which may represent hit compounds for developing multi-target anticanceragents.
