  The present invention relates to a compound for detecting phosgene and DCP (diethyl chlorophosphate) and a composition for detecting phosgene and DCP (diethyl chlorophosphate) comprising the said compound. More precisely, the compound for detecting phosgene and DCP of the present invention can selectively detect phosgene and DCP either in the liquid phase of gas phase by detecting the changes of fluorescence and color development very quickly within a few seconds with nM sensitivity. Therefore, the compound can also be effectively used as an ingredient for the composition and kit for the detection of one or more materials selected from the group consisting of phosgene and DCP.

  The present invention relates compounds and compositions for interfering with the association of Myc and Max. These compounds and compositions are useful in methods for inhibiting growth or proliferation of a cell. Methods of inhibiting growth or proliferation of a cell comprise contacting the cell with an amount of a compound that interferes with Myc and Max association effective to inhibit growth or proliferation of the cell. The compounds exhibit increased inhibitory activity against c-Myc relative to the known c-Myc inhibitor small-molecule benzofurazan N-([1,1′-biphenyl]-2-yl)-7-nitrobenzo[c][1,2,5]oxadiazol-4-amine (10074-G5).

  本发明涉及一种干扰Myc和Max结合的化合物和组合物。这些化合物和组合物在抑制细胞生长或增殖的方法中非常有用。抑制细胞生长或增殖的方法包括将干扰Myc和Max结合的化合物与细胞接触，有效地抑制细胞的生长或增殖。这些化合物对c-Myc表现出比已知的c-Myc抑制剂小分子苯并呋喃唑酮N-([1,1′-联苯基]-2-基)-7-硝基苯并[c][1,2,5]噁二唑-4-胺（10074-G5）更高的抑制活性。
