Sirt1/2-IN-3 (compound PS9) is a dual inhibitor of SIRT1/2 with IC₅₀s of 1.4 μM (SIRT1) and 2.0 μM (SIRT2), respsectivley. Sirt1/2-IN-3 completely blocks p53 deacetylation, and increase of p53 and α-tubulin acetylation. Sirt1/2-IN-3 induces apoptosis and shows anti-proliferation activity against human leukemia cell lines.

Description	Sirt1/2-IN-3 (compound PS9) is a dual inhibitor of SIRT1/2 with IC₅₀s of 1.4 μM (SIRT1) and 2.0 μM (SIRT2), respsectivley. Sirt1/2-IN-3 completely blocks p53 deacetylation, and increase of p53 and α-tubulin acetylation. Sirt1/2-IN-3 induces apoptosis and shows anti-proliferation activity against human leukemia cell lines^[1].
IC₅₀ & Target	IC50: 1.4 μM (SIRT1), 2.0 μM (SIRT2), 72.3 μM (SIRT3)^[1]
In Vitro	Sirt1/2-IN-3 (compound hsa55) (5 μM; 48 h) induces apoptosis in different tumor cells, with IC₅₀s of 6.5 μM (MV4-11), 9.2μM (MOLM-13), 27.2 μM (THP1), 17.4 μM (Jurkat), respectively^[1].Sirt1/2-IN-3 (100 μM; 30 min) decreases the thermal stability of both SIRT1 and SIRT2 proteins at different temperatures, and also (25 μM, 30 μM; 6 h) increase level of the acetylated form of p53 and α-tubulin in MOLM-13 cells^[1].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
