The synthesis and biological activity of indoloazepines and acid amine salts thereof which are structurally related to naturally-occurring hymenialdisine is disclosed. Naturally-occurring hymenialdisine obtained from the sponge is a potent inhibitor of production of cytokines interleukin-2 (IL-2) and tumor necrosis factor-&agr; (TNF-&agr;). The chemically-synthesized indoloazepines of the invention also inhibit production of IL-2 and TNF-&agr;. The indoloazepines are useful for treating inflammatory diseases, particularly diseases associated with kinases NF-&kgr;B or GSK-3&bgr; activation or NF-&kgr;B activated gene expression products. The indoloazepines are useful for the treatment of cancer by the inhibition of kinases CHK1 and CHK2.
本文披露了与天然存在的海绵素结构相关的吲哚环庚烷和其酸胺盐的合成和生物活性。从海绵获得的天然存在的海绵素是细胞因子白细胞介素-2(IL-2)和肿瘤坏死因子-α(TNF-α)产生的有效抑制剂。发明的化学合成的吲哚环庚烷也抑制IL-2和TNF-α的产生。这些吲哚环庚烷对治疗炎症性疾病特别有效,尤其是与激酶NF-κB或GSK-3β激活或NF-κB激活的基因表达产物相关的疾病。这些吲哚环庚烷通过抑制激酶CHK1和CHK2对癌症的治疗也是有效的。
