Biological Activity

Description

MGH-CP1 is a potent and selective inhibitor of transcriptional enhanced associate domain (TEAD) palmitoylation. MGH-CP1 exhibits dose-dependent and potent inhibition of TEAD2/4 auto-palmitoylation in vitro with IC50 of 710 nM and 672 nM, respectively.

Targets

TEAD4 ^[1] (Cell-free assay)	TEAD2 ^[1] (Cell-free assay)
672 nM	710 nM

In vitro

MGH-CP1 exhibits dose-dependent and potent inhibition of TEAD2/4 auto-palmitoylation in vitro. MGH-CP1 treatment markedly decreases the palmitoylation levels of endogenous or ectopically expressed TEAD proteins in cells. MGH-CP1 does not affect auto-palmitoylation of several ZDHHC-family palmitoyl acyltransferases, suggesting its selectivity toward TEADs. MGH-CP1 is a selective small-molecule pan-TEAD inhibitor by directly targeting TEAD auto-palmitoylation.^[1]

In vivo

MGH-CP1 inhibits TEAD activity in Lats1/2 KO intestine in vivo. MGH-CP1 can effectively inhibit the palmitoylation of TEAD proteins in the intestinal epithelium. MGH-CP1 is well tolerated and has no apparent adverse effect on overall animal health or body weight after 2 weeks of treatment. In contrast to its lack of apparent effect in wild-type intestine, MGH-CP1 treatment effectively inhibits upregulation of the TEAD target genes, CTGF and ANKRD1, in Lats1/2 KO intestine.^[1]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HEK293T cells, Lats1/2 conditional MEFs, MDA-MB-231 cells, Huh7 cells Concentrations 0.1 μM, 0.3 μM, 0.6 μM, 1 μM, 1.2 μM, 2.5 μM, 3 μM, 5 μM, 10 μM Incubation Time 24 h Method HEK293T cells, Lats1/2 conditional MEFs and MDA-MB-231 cells are cultured in DMEM supplemented with 10% FBS and 1% penicillin/streptomycin. For Lats1/2 conditional MEFs carrying CMV-CreER, Lats1/2 is deleted by incubation with 4-OH Tamoxifen (2.5 mM) in DMEM for 4 days prior to further experiment. Transfection in HEK293T cells is performed using Lipofectamine 2000. For luciferase reporter assays, HEK293T cells are transfected with the luciferase reporter constructs TBS-Luc, Super TOP-FLASH (STF), Gli-BS-Luc, BRE-Luc, and NF-kB-Luc, as well as the expression vectors of pGIPZ-YAP5SA, pGIPZ-YAP6SA, pGIPZ-TAZ4SA, pLV-b-Catenin-DN90, pCIG-Wnt3a, pCMV-LRP5C, pCIG-BMP4, pCIG-Gli1, pGIPZ-IKBKE and pCMV-Renilla lucifease. Luciferase activities are conducted 24 hours after transfection using the dual-lucif-erase reporter kit in the cells treated with or without Wnt3A, LiCl or MGH-CP1.
