Design, synthesis, and structure activity relationship (SAR) studies of novel imidazo[1,2-a] pyridine derivatives as Nek2 inhibitors

Never in mitosis (NIMA) related kinase 2 (Nek2) is involved in multiple cellular processes such as cell cycle checkpoint regulation, cell division, DNA damage response and cell apoptosis. Nek2 has been reported to be overexpressed in various tumors and correlated with poor prognosis. Herein, a series of imidazo[1,2-a] pyridines Nek2 inhibitors were designed, synthesized, and their biological activities were investigated. Besides, structure activity relationship analysis of these compounds were performed in the MGC-803 cell. The screening results are promising, and compound 28e shows good proliferation inhibitory activity with an IC50 of 38 nM. The results would be helpful to design and develop more effective Nek2 inhibitors for the treatment of gastric cancer.

Preparation method of 3-hydroxythiophene-2-carboxylate compound

The invention provides a preparation method of a 3-hydroxythiophene-2-carboxylate compound. The preparation method comprises the following steps of enabling a formula as shown in the description to carry out a condensation reaction with E-3-methyl methoxyacrylate in an alkaline condition to form the 3-hydroxythiophene-2-carboxylate compound, wherein R is selected from any one of C1 to C10 alkyl and C2 to C10 alkenyl. The formula as shown in the description and the E-3-methyl methoxyacrylate are adopted as raw materials, and are enabled to carry out the condensation reaction in the alkaline condition to form a thiophene ring; the reaction is easy to carry out; the reaction condition is easy to control; and the product yield is higher in a proper condition. The cost of the E-3-methyl methoxyacrylate is lower compared with that of 2-methyl chloroacrylate or methyl propiolate; and therefore, the synthetic process cost of the 3-hydroxythiophene-2-carboxylate compound is decreased.
