SKLB-11A

고객리뷰

Based on 1 Customer Validation

SKLB-11A is a selective, orally active and allosteric SIRT3 (sirtuin 3) agonist with a K_d value of 4.7 μM. SKLB-11A is highly selective for other members of the SIRT family. SKLB-11A activates autophagy-related signaling pathways, prevents mitochondrial dysfunction, improves cardiac function in Doxorubicin (HY-15142A)-induced cardiotoxicity and myocardial ischemia/reperfusion models.

IC₅₀ & Target

SIRT3

4.7 μM (Kd)

All Sirtuin Isoforms :

In Vitro

SKLB-11A enhances SIRT3 deacetylation activity with an EC₅₀ of 21.95 μM^[1].
SKLB-11A (0.625-5 μM; 24 h) does not alter SIRT3 protein levels but significantly enhances SIRT3 activity in H9c2 cells^[1].
SKLB-11A binds to SIRT3 with high affinity and enhances its interaction with the p53-Ac substrate^[1].
SKLB-11A (5-20 μM; 24 h) ameliorates Doxorubicin-induced mitochondrial damage and promotes SIRT3-mediated autophagy in H9c2 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[1]

Cell Line:

H9c2 cells
Concentration:

0.625 μM, 1.25 μM, 2.5 μM, 5 μM
Incubation Time:

24 h
Result:

Induced deacetylation at K122 and K68, resulting in enhanced MnSOD enzymatic activity.
Activated endogenous SIRT3 deacetylation in H9c2 cells.

Western Blot Analysis^[1]

Cell Line:

H9c2 cells
Concentration:

5 μM, 10 μM, 20 μM
Incubation Time:

24 h
Result:

Increased LC3-II expression and reduced p62 levels, indicating enhanced autophagic flux.
Increased the expression of PINK1 and Parkin, and promoted colocalization of mitochondria with Parkin and LC3-II.

In Vivo

SKLB-11A (10-20 mg/kg; oral gavage; daily; for 7 days) pretreatment can repress Doxorubicin-induced cardiac dysfunction in mice^[1].
SKLB-11A (20 mg/kg; oral gavage; daily; for 7 days) treatment alleviated ischemia/reperfusion (I/R)-induced myocardial injury in mice^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Male C57BL/6J mice (8 weeks, ~23 g)^[1]
Dosage:

10 and 20 mg/kg/day
Administration:

Oral gavage; daily; for 7 days; then injected Doxorubicin intraperitoneally for 2 weeks
Result:

Significantly restored left ventricular ejection fraction (EF) and fractional shortening (FS) in a dose-dependent manner.
Partially reversed Doxorubicin-induced weight loss and reduced serum markers of myocardial injury, including LDH, CK-MB, and BNP.
Preserved myocardial structure and alleviated pathological damage.
Demonstrated no apparent toxicity at effective doses, as evidenced by preserved organ histology in the heart, liver, spleen, lungs, and kidneys.

Animal Model:

Male C57BL/6J mice (8-12 weeks old) was induced myocardial ischemia-reperfusion (I/R) injury^[1].
Dosage:

20 mg/kg
Administration:

Oral gavage; daily; for 7 days
Result:

Restored cardiac function impaired by I/R injury.
Partially reversed I/R-induced elevations in serum myocardial injury markers, including LDH, CK-MB, and BNP.
Markedly reduced I/R-induced cardiac fibrosis.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
