SCAL-255

Customer Review

Based on 1 Customer Validation

SCAL-255 is a potent mitochondrial complex I (CI) inhibitor with an IC₅₀ of 1.14 μM. SCAL-255 blocks mitochondrial function, inhibits oxygen consumption rate (OCR), induces reactive oxygen species (ROS) production, and reduces MMP. SCAL-255 can be used in the research of oxidative phosphorylation (OXPHOS)-dependent cancers, such as colorectal cancer (CRC) and acute myeloid leukemia (AML), etc.

For research use only. We do not sell to patients.

In Vitro

SCAL-255 (0.01-10 nM; 96 h) significantly inhibits the proliferation of human colorectal cancer cell line HCT116 and acute myeloid leukemia cell line KG-1. SCAL-255 has little inhibitory effect on NCM460 cells^[1].
SCAL-255 (2 nM, 10 nM; 24 h) inhibits the oxygen consumption rate (OCR), activates glycolysis, and changes the energy metabolism of HCT116 cells^[1].
SCAL-255 (0.13-2 nM) induces the production of ROS and reduces the MMP in HCT116 and KG-1 cells^[1].

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

In Vivo

SCAL-255 (5 mg/kg; intraperitoneal injection; five consecutive days per week for 24 days) inhibits tumor growth in the KG-1 subcutaneous xenograft tumor model of NOD-SCID mice, with a tumor growth inhibition rate of 61.5%, and has no significant effects on the body weight, blood biochemical parameters, routine blood indices, and histology of major organs of the mice^[1].
The maximum tolerated dose (MTD) values of SCAL-255 is 68 mg/kg in mice^[1].

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

Animal Model:

Female NOD-SCID mice (18-20 g, 5 weeks) inoculated with KG-1 cells^[1].
Dosage:

5 mg/kg
Administration:

Intraperitoneal injection, five consecutive days per week for 24 days
Result:

Exhibited adequate antitumor activity with a tumor growth inhibitory (TGI) rate of 61.5%.
No significant change of body weight, blood biochemical parameters, routine blood indexes, and histology of major organs were observed.

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.
