The present invention relates to compositions for transfecting a nucleic acid molecule into a cell and their applications. The present invention is directed to a composition suitable for transfecting a nucleic acid molecule into a cell, preferably a eukaryotic cell, comprising (i) at least one compound of general formula (II) or a tautomer, mesomer, racemate, enantiomer, diastereomer, or mixture thereof, or an acceptable salt thereof, and (ii) an acceptable excipient, buffering agent, cell culture medium, or transfection medium, wherein Y11, Y22, Y33, Z11, Z22, Z33, Z44, Z55, Z66, Z77, X11, X22, R33, P++, R, T, U and V are as defined in the description. The present invention also relates to uses of said composition and to a method for in vitro or ex vivo transfection of live cells.

Paragraph 0093, (2017/08/25)
Provided are 2-substituted-N-[5-(2-(N-aryl methylene)amino-1,3,4-thiadiazole)-methylene]-benzimidazole and a preparation method and an application thereof. The preparation method comprises the steps: firstly, with a benzimidazole compound and potassium chloroacetate as raw materials and ethanol as a solvent, carrying out a reflux reaction to obtain a 1-carboxymethyl-benzimidazole compound; then with polyphosphoric acid, the 1-carboxymethyl-benzimidazole compound and thiosemicarbazide as raw materials, carrying out a reflux reaction to obtain 2-substituted-N-[5-(2-amino-1,3,4-thiadiazole)-methylene]-benzimidazole; then with 2-substituted-N-[5-(2-amino-1,3,4-thiadiazole)-methylene]-benzimidazole, aromatic aldehyde and p-toluenesulfonic acid as raw materials, carrying out a solid-phase reaction, and thus obtaining 2-substituted-N-[5-(2-(N-aryl methylene)amino-1,3,4-thiadiazole)-methylene]-benzimidazole. The preparation method has the advantages of simple reaction process, low equipment requirements, simple operation, relatively high target product yield, and small environmental pollution, and the prepared 2-substituted-N-[5-(2-(N-aryl methylene)amino-1,3,4-thiadiazole)-methylene]-benzimidazole can be applied in preparation of drugs inhibiting escherichia coli.
