othioamid+ ++ e 1-oxide (8a, RP 49356) and analogues is reported. These compounds constitute a new structural class of K(+)-channel opener. The effects of changes in pyridyl group, thioamide, and thiane ring on in vitro K(+)-channel opening reactivity are discussed. A 3-pyridyl or 3-quinolyl group, a small N-alkyl thioamide function, and a thiane oxide ring, in which the sulfoxide is in a trans relationship
报道了反式-(+-)-N-甲基-2-(3-吡啶基)-2-四氢硫代吡喃氨基甲磺酰胺+++ e 1-氧化物(8a,RP 49356)和类似物的合成和生物活性。这些化合物构成K(+)通道开放剂的新结构类。讨论了吡啶基,硫代酰胺和硫杂环上的变化对体外K(+)通道开放反应性的影响。为了活性,优选3-吡啶基或3-喹啉基,小的N-烷基硫代酰胺官能团和氧化亚砜环,其中亚砜与硫代酰胺具有反式关系。选择的化合物在降压麻醉的大鼠中静脉内测试降压作用,其活性反映了其体外K(+)通道的开放活性。

values ranging from 80 nM to 500 nM. Further, these compounds are surprisingly effective in inhibiting a wide variety of cancer cells, including osteosarcoma, epithelial lung carcinoma, non-small cell lung carcinoma, three different pancreatic cancer cell lines, two different glioblastoma cell lines, metastatic breast cancer, melanoma, and prostate cancer. Moreover, the disclosed compounds effectively disrupt angiogenesis and significantly inhibited tumors in nude mice derived from human epithelial lung carcinoma tumors. Accordingly, the disclosed compounds, pharmaceutical compositions comprising the compounds, methods of inhibiting cell proliferation, methods of treating subjects with cancer, and methods of preparing the disclosed compounds are provided.
