FAZ-3780
Based on 2 publication(s) in Google Scholar
FAZ-3780 is an inhibitor that binds to the NTF2L domain of G3BP1/2. FAZ-3780 binds to the NTF2L nsP3 of G3BP1 with high affinity, with a Kd of 0.15 μM and a Pep-FRET IC50 of 0.7 μM. FAZ-3780 targets the protein-protein interaction domain of G3BP1/2, and specifically inhibits the co-condensation of G3BP1, caprin 1 and RNA in vitro. FAZ-3780 inhibits stress granule formation and disassembles pre-formed stress granules. FAZ-3780 can be used in studies related to cancer and neurodegenerative diseases.

Biological Activity
FAZ-3780 (G3Ib) (5-50 μM; 2 h) dose-dependently disrupts the interactions between G3BP1 and endogenous caprin 1 as well as USP10 in U2OS cell lysates[1].
FAZ-3780 (25-50 μM; 2 h) disrupts the interaction between the isolated NTF2L domain of G3BP1 and endogenous caprin 1 and USP10 in HEK293T cell lysates[1].
FAZ-3780 (0.001-100 μM; 70 min) potently inhibits the in vitro co-condensation of human G3BP1, caprin 1 and RNA, with an IC50 of 3.450 μM[1].
FAZ-3780 (5-50 μM; 50 min) inhibits sodium arsenite-induced stress granule formation in U2OS/HeLa G3BP1-GFP cells, rapidly disassembles stress granules, and prevents the localization of TDP-43 to stress granules[1].
FAZ-3780 (5-50 μM; 24 h) exhibits sustained and potent inhibitory activity against sodium arsenite-induced stress granule formation in U2OS cells[1].
FAZ-3780 (50 μM; 50 min) inhibits heat shock-induced stress granule formation in U2OS G3BP1-GFP cells and rapidly disassembles pre-formed heat shock-induced stress granules in cells[1].
