Customer Review

Based on 1 Customer Validation

Osthenol (Ostenol) is a reversible, selective, competitive inhibitor of hMAO-A (IC₅₀=0.74 μM, K_i=0.26 μM), with antifungal and antibacterial activity. Osthenol inhibits the oxidative deamination of hMAO-A and regulates the metabolism of monoamine neurotransmitters. Osthenol also inhibits the PI3K/AKT signaling pathway to induce apoptosis of colon cancer cells, arrest the cell cycle at the G1 phase, and inhibit cell proliferation. Osthenol is mainly used in the study of neurological diseases and cancer, especially depression-related MAO-A targeted intervention and colon cancer.

Apoptosis Analysis^[2]

Cell Line:

Apoptosis Assay (HCT116 Cells) HCT116
Concentration:

25-100 μM
Incubation Time:

48 h
Result:

Total apoptotic cells rose from 7.06% (control) to 30.12% (25 μM), 33.11% (50 μM), and 52.5% (100 μM).
Dose-dependently increased the activation of caspase-3, -8, and -9 (cleaved caspase levels increasing).

In Vivo

Osthenol (5 mg/kg; intravenous injection; single dose) has a rapid distribution characteristic in male ICR mice, with initial blood concentration C₀=14.3 μg/mL, T_1/2=47.0 min, AUC_last=211.5 μg·min/mL, MRT_last=22.5 min^[5].
Osthenol (5 mg/kg, 20 mg/kg; oral gavage; single dose) has extremely low bioavailability in male ICR mice (0.43% and 0.02%, respectively), and is rapidly metabolized to sulfonylated (M1) and glucuronidated (M2) conjugates after oral administration^[5].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

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.
