Kundenbewertung

Based on 1 Customer Validation

Levoleucovorin (Levofolinic acid; Levofolene) is the pharmacologically and orally active levoisomer of Folinic acid (HY-17556), a synthetic folate analogue. Levoleucovorin can inhibit LOXL2 with an IC₅₀ of 68.81 μM. Levoleucovorin can inhibit cancer cells proliferation, migration and induce apoptosis. Levoleucovorin can be used as a rescue agent for high-dose Methotrexate (HY-14519). Levoleucovorin can reduce the frequency of embryonic malformations. Levoleucovorin can be used for the research of can and endocrinology, such as breast cancer and osteosarcoma.

IC₅₀ & Target^[1]

LOXL2

68.81 nM (IC₅₀)

In Vitro

Levoleucovorin inhibits recombinant human LOXL2 protein with an IC₅₀ of 68.81 μM^[1].
Levoleucovorin (72 h) inhibits proliferation of MDA-MB 231 breast cancer cells with a GI₅₀ of 55.91 μM and MCF-7 breast cancer cells with a GI₅₀ of 79.20 μM^[1].
Levoleucovorin (15-60 μM; 12 h) dose-dependently inhibits HGF-induced trans-endothelial migration of MDA-MB 231 and MCF-7 breast cancer cells across HUVEC cell layers^[1].
Levoleucovorin (30-80 μM；72 h) induces dose-dependent apoptosis in MDA-MB 231 and MCF-7 breast cancer cells^[1].

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

Apoptosis Analysis^[1]

Cell Line:

MDA-MB 231 breast cancer cell line, MCF-7 breast cancer cell line
Concentration:

30 μM, 60 μM (MDA-MB 231); 40 μM, 80 μM (MCF-7)
Incubation Time:

72 h
Result:

Significantly increased Annexin V-positive early and late apoptotic populations in MDA-MB 231 cells in a dose-dependent manner, with total apoptosis increasing 17.93% at 30 μM and 33.11% at 60 μM.
Significantly increased Annexin V-positive early and late apoptotic populations in MCF-7 cells in a dose-dependent manner, with total apoptosis increasing 15.36% at 40 μM and 30.38% at 80 μM.

In Vivo

Levoleucovorin (10.75-43 μmol/kg per day; i.g.,; daily; initiated 2 weeks pre-mating through gestation) reduces the frequency of embryonic malformations in a dose-dependent manner, with the 43 μmol/kg per day dose lowering overall malformation frequency to 33.3%^[3].

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

Animal Model:

Folbp1 knockout (female; mated to Folbp1-/- males; prenatal developmental model)^[3]
Dosage:

10.75 μmol/kg per day; 21.5 μmol/kg per day; 43 μmol/kg per day
Administration:

I.g.; daily; initiated 2 weeks pre-mating through gestation
Result:

Reduced malformation frequency to 66.7% at 10.75 μmol/kg per day, 65.8% at 21.5 μmol/kg per day, and 33.3% at 43 μmol/kg per day.
Decreased neural tube defects to 35.2% (10.75 and 21.5 μmol/kg), 16.7% (43 μmol/kg).
Decreased craniofacial defects to 46.2% (10.75 and 21.5 μmol/kg), 19.4% (43 μmol/kg).
Demonstrated significant inverse dose-dependent relationship with all malformation categories.
Resulted in a mean litter size of 3.70 ± 2.63 at 43 μmol/kg per day, significantly lower than wild-type controls.

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.
