  The present invention relates to non-steroidal ligands for use in nuclear receptor-based inducible gene expression system, and a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene.

  本发明涉及用于核受体基础诱导基因表达系统的非甾体配体，以及一种调节外源基因表达的方法，其中包括一个包含：DNA结合结构域；配体结合结构域；转活化结构域；和一个配体的ecdysone受体复合物与包含外源基因和响应元件的DNA构建物接触；其中外源基因受响应元件控制，并且在配体存在的情况下DNA结合结构域与响应元件结合导致基因的激活或抑制。

  tetrakis(dimethylamido)zirconium or -hafnium gave the corresponding (chelate ligand)MX3 systems in a variety of cases. Some of these gave very active ethene polymerization catalysts upon activation with methylalumoxane. Six of the neutral aminoalkylpyridines were characterized by X-ray diffraction, as were eight of the zirconium or hafnium complexes and two aluminum chelate complex systems.
