sirt6 in 1

SIRT6-IN-1, a novel SIRT6 inhibitor, reduces glycemia and improves oral glucose tolerance in unfed wild-type mice.

SZU-B6, a PROTAC degrader, targets and degrades SIRT6 with DC50 values of 45 nM in SK-HEP-1 cells and 154 nM in Huh-7 cells. It inhibits the proliferation of SK-HEP-1 cells with an IC50 of 1.51 μM and suppresses colony formation in both SK-HEP-1 and Huh-7 cell lines. Additionally, SZU-B6 induces apoptosis in SK-HEP-1 cells and causes cell cycle arrest at the G2 M phase. It demonstrates anti-tumor activity in murine models.

OSS_128167 (SIRT6-IN-1) is a specific SIRT6 inhibitor, and for SIRT6(IC50=89 μM), SIRT1(IC50=1578 μM) and SIRT2(IC50=751 μM).

SIRT6-IN-3 (compound 8a), a selective SIRT6 inhibitor (IC50 = 7.49 μM), impedes the proliferation of pancreatic ductal adenocarcinoma (PDAC) cells and prompts apoptosis. It enhances the responsiveness of cancer cells to gemcitabine by obstructing the DNA damage repair pathway, thus serving as a valuable tool in pancreatic cancer research [1].

MDL-811, an allosteric activator of SIRT6, markedly enhances the deacetylation of histone H3 at lysine residues 9, 18, and 56 (H3K9Ac, H3K18Ac, and H3K56Ac), presenting potential utility in colorectal cancer research [1].
