Biological Activity

SWTX-143 is a potent, irreversible and covalent YAP/TAZ-TEAD inhibitor with IC50 of 12 nM in luciferase reporter assays, binds to the palmitoylation pocket of all four TEAD isoforms, inhibits Hippo pathway-mutant cancer cells.

SWTX-143 potently represses luciferase expression from the TEAD reporter (IC50=12 nmol/L) while not affecting the viability of HEK293 cells.

SWTX-143 is sufficient to evoke a long-lasting transcriptional impact.

SWTX-143 inhibits the proliferation of Hippo pathway-mutant cancer cell lines with IC50 of 5-207 nM against three distinct desothelioma cancer cell lines that are characterized by and depend on loss-of-function alterations in NF2 (Mero-14, NCI-H226, and CI-H2052) and one that is deficient in ATS1 and LATS2 (MSTO-211H).

SWTX-143 only modestly impacts the proliferation of the NCI-H28 and NCI-H2452 mesothelioma, HeLa, SiHa, and CaSki cancer cell lines which lack genetic alterations in known Hippo pathway components (Hippo-WT).

SWTX-143 (10, 25, and 50 mg/kg) causes regression of NF2-deficient human mesothelioma xenografts.

SWTX-143 also selectively impairs the growth of NF2-mutant kidney cancer cell lines, blocks Hippo pathway transcriptional output and causes tumor regression in preclinical mesothelioma models.
