3'3'-cGAMP is a second messenger produced in bacteria by specific dinucleotide cyclases. It contains canonical 3'5'-phosphodiester bonds and regulates chemotaxis, colonization, and other cellular functions. 3'3'-cGAMP shows weaker binding to the adapter protein stimulator of interferon genes (STING; Kd = 1.04 μM) than 2'2'-cGAMP and 2'3'-cGAMP but has similar binding affinity to 3'2'-cGAMP (Kd = 1.61 μM) and cyclic di-GMP . 3'3'-cGAMP induces IFN-β mRNA expression in L929 cells (EC50 = 40.5 nM).
JMS-17-2 hydrochloride, a highly potent and selective CX3CR1 antagonist with an IC 50 value of 0.32 nM, effectively impedes the metastatic seeding and colonization process of breast cancer cells.
hCAIX-IN-8 (compound 7i) is a highly potent and selective inhibitor of hCAIX, demonstrating potent inhibitory activity against CAIX with an IC50 value of 0.024 μM. It also exhibits inhibitory activity against CAII and CAVA with IC50 values of 1.99 μM and 1.10 μM, respectively. Furthermore, hCAIX-IN-8 exhibits anti-proliferative effects and low toxicity. It effectively reduces the occurrence of epithelial-to-mesenchymal transitions and promotes apoptosis. Additionally, hCAIX-IN-8 effectively inhibits cell migration and colonization potential [1].
The Staphylococcus aureus transpeptidase Sortase A (SrtA) anchors virulence and colonization-associated surface proteins to the cell wall. SrtA selectively recognizes a C-terminal LPXTG motif. SrtA readily reacts with its native substrate Abz-LPETG-Dap(DN
