Paragraph 0069-0071; 0084-0086, (2017/09/01)
The invention belongs to the field of chemical pharmaceuticals, and particularly relates to a 2-oxadiazole-3-aminothiophene thieno-[2,3-b] pyridine derivative and a preparing method and application thereof. The structure of the 2-oxadiazole-3-aminothiophene thieno-[2,3-b] pyridine derivative is shown in the formula I. A compound of the 2-oxadiazole-3-aminothiophene thieno-[2,3-b] pyridine derivative has the good HCV inhibitory effect, and meanwhile shows the low cytotoxicity, and a new method is provided for development of an anti-HCV inhibitor. The general formula is defined in the description.

Here, we describe the selection and optimization of a chemical series active in both a full-length and a fragment-based Huntington's disease (HD) assay. Twenty-four thousand small molecules were screened in a phenotypic HD assay, identifying a series of compounds bearing a 3-hydroxy-3- trifluoromethylpyrazole moiety as able to revert the toxicity induced by full-length mutant Htt by up to 50%. A chemical exploration around the series led to the identification of compound 4f, which demonstrated to be active in a Htt171-82Q rat primary striatal neuron assay and a PC12-Exon-1 based assay. This compound was selected for testing in R6/2 mice, in which it was well-tolerated and showed a positive effect on body weight and a positive trend in preventing ventricular volume enlargment. These studies provide strong rationale for further testing the potential benefits of 3-hydroxy-3-trifluoromethylpyrazoles in treating HD.
