Sirt1/2-IN-2 (compound hsa55) is a dual inhibitor of SIRT1/2 with IC50s of 1.8 μM (SIRT1) and 2.4 μM (SIRT2), respsectivley. Sirt1/2-IN-2 completely blocks p53 deacetylation, and increase of p53 and α-tubulin acetylation. Sirt1/2-IN-2 induces apoptosis and shows anti-proliferation activity against human leukemia cell lines[1].
PARP-1/2-IN-2-IN-1 (Compound 12e) is a PARP1/2/CDK12 inhibitor (IC50: 34, 30 and 285 nM respectively). PARP-1/2-IN-2 inhibits DNA damage repair, promotes cell cycle arrest and apoptosis. PARP-1/2-IN-2 inhibits the growth of TNBC cells and TNBC xenograft tumor[1].
Lysyl hydroxylase 2-IN-2 (compound 13) is a potent Lysyl hydroxylase 2 (LH2) inhibitor, with the IC50 of approximately 500 nM. Lysyl hydroxylase 2-IN-2 inhibits the migration in 344SQ WT cells, but not impedes the migration of the same cell line with an LH2 knockout cells[1].
