https://www.selleckchem.com/products/pt2977.html Mechanistically, we found that shikonin increased miR-183-5p expression and inhibited expression of transcription factor Snail protein. The mimics of miR-183-5p reduced, while the inhibitors of miR-183-5p reversed shikonin-inhibited Snail protein expression. In addition, shikonin decreased Vimentin, increased E-cadherin protein expressions and E-cadherin promoter activity, the latter was reversed in cells transfected with exogenous Snail overexpression vectors. Moreover, silencing of E-cadherin significantly abolished shikonin-inhibited cervical cancer cell growth. Similar findings were also observed in vivo using one xenograft mouse model. Conclusion Our results show that shikonin inhibits EMT through inhibition of Snail and stimulation of miR-183-5p expressions, which resulted in induction of E-cadherin expression. Thus, blockade of EMT could be a novel mechanism underlying the anti-cervical cancer effects of shikonin. © 2020 Tang et al.Background The bacterial cell envelope is comprised of the cell membrane and the cell wall. The bacterial cell wall provides rigidity to the cell and protects the organism from potential harmful substances also. Cell wall biosynthesis is an important physiological process for bacterial survival and thus has been a primary target for the development of antibacterials. Antimicrobial peptides that target bacterial cell wall assembly are abundant and many bind to the essential cell wall precursor molecule Lipid II. Methods We describe the structure-to-activity (SAR) relationship of an antimicrobial peptide-derived small molecule 7771-0701 that acts as a novel agent against cell wall biosynthesis. Derivatives of compound 7771-0701 (2-[(1E)-3-[(2E)-5,6-dimethyl-3-(prop-2-en-1-yl)-1,3-benzothiazol-2-ylidene]prop-1-en-1-yl]-1,3,3-trimethylindol-1-ium) were generated by medicinal chemistry guided by Computer-Aided Drug Design and NMR. Derivatives were tested for antibacterial activity and Lip
