Synthesis of urea analogues bearing N-alkyl-N'-(thiophen-2-yl) scaffold and evaluation of their innate immune response to toll-like receptors
摘要:
Previous high throughput virtual screening of 10 million-compound and following cell based validation led to the discovery of a novel, nonlipopeptide-like chemotype ZINC 6662436, as toll-like receptor 2 (TLR2) agonists. In this report, compounds belonging to four areas of structural modification of ZINC6662436 were evaluated for biological activity using human HEK-Blue TLR2 reporter cells, and human THP-1 monocytic cells, yield SMU-C13 as an optimized, direct and high potent (EC50 = 160 nM) agonist of human TLR2. Moreover, preliminary mechanism studies indicated that SMU-C13 through activates TLR1 and TLR2 then stimulates the NF-kappa B activation to trigger the downstream cytokines, such as TNF-alpha and secreted alkaline phosphatase (SEAP).

reported the identification of compound 1 as SHP2 inhibitor. Fragment-based ligand design, De novo design, ADMET and Molecular docking were performed to explore potential selective SHP2 allosteric inhibitorsbased on SHP836. The results of docking studies indicated that the selected compounds had higher selective SHP2 inhibition than existing inhibitors. Compound 1 was found to have a novel selectivity
