GIT1-IN-1
GIT1-IN-1 is an inhibitor of ARF GTPase-activating protein 1 (GIT1) with a KD of 6.2 μM. GIT1-IN-1 induces apoptosis (apoptosis) in liver and colon cancer cells, arrests the cell cycle at the G2/M phase, and inhibits cell proliferation, colony formation and migration. GIT1-IN-1 inhibits the activities of MEK and ERK, reduces the expression level of cyclin D1, and stabilizes cyclin B1 protein in liver and colon cancer cells. GIT1-IN-1 can be used in the research of liver cancer and colon cancer.

GIT1-IN-1 (Compound C3) (10-100 μM; 24 h) inhibits viability and proliferation of HepG2, Hep3B, MzChA-1, HT-29, and RKO liver and colon cancer cells with an IC50 of around 20 μM, but does not affect non-malignant AML12, HEK293, or primary mouse or human hepatocytes at concentrations up to 100 μM[1].
GIT1-IN-1 (1-5 μM; 24 h) induces dose-dependent G2/M phase arrest in HepG2 and RKO liver and colon cancer cells, but does not affect cell cycle progression in non-malignant AML12 or HEK293 cells[1].
GIT1-IN-1 (5 μM; 24-48 h) induces time-dependent apoptosis in RKO colon cancer cells and increases apoptosis and necrosis in HepG2 liver cancer cells after 48 hours, but does not induce cell death in non-malignant AML12, HEK293, or primary mouse or human hepatocytes[1].
GIT1-IN-1 (1-10 μM; 24 h) inhibits clonogenic potential of HepG2 liver cancer cells and RKO colon cancer cells in a dose-dependent manner, but does not affect non-malignant AML12 cells[1].
GIT1-IN-1 (1-2 μM; 24 h) inhibits migration of RKO colon cancer cells and MzChA-1 liver cancer cells in a dose-dependent manner[1].
GIT1-IN-1 (5-10 μM; 24 h) at 10 μM disrupts GIT1-MAT2B and MEK1/2-cRAF/BRAF/ERK1/2/GIT1 interactions, and at 5 μM disrupts GIT1-CDC20, GIT1-APC3, cyclin B1-CDC20, and cyclin B1-APC3 interactions while enhancing GIT1-cyclin B1 interactions in HepG2 and RKO liver and colon cancer cells[1].
GIT1-IN-1 (2-10 μM; 24 h) inhibits MEK and ERK pathway activity, as measured by reduced pMEK1/2, pERK1/2, and cyclin D1 levels, in HepG2, RKO, and MC38 liver and colon cancer cells, but does not affect pathway activity in non-malignant AML12 cells[1].
GIT1-IN-1 (2-5 μM; 24 h) increases cyclin B1 protein stability, cyclin B1-CDK1 complex formation, and CDK1 activity in HepG2 and RKO liver and colon cancer cells, as indicated by a prolonged cyclin B1 half-life, reduced inhibitory CDK1 phosphorylation, and increased activating cyclin B1 phosphorylation[1].
