    Description: 10-Methoxycamptothecin possesses high anti-cancer activity.

    Drug Res (Stuttg). 2015 Mar;65(3):147-52.
    A simple HPLC method with fluorescence detection for simultaneous determination of 10-methoxycamptothecin and its metabolite 10-hydroxycamptothecin in rat liver tissue.[Pubmed: 24782285]
    A simple HPLC method to determine the amount of 10-Methoxycamptothecin (MCPT) and its major metabolite 10-hydroxycamptothecin (HCPT) in rat liver tissue was developed in the present study.
    METHODS AND RESULTS:
    Camptothecin (CPT) was used as internal standard (IS). A piecewise linear function was used over lower and higher concentrations, respectively. The calibration curves were linear (r (2) >0.99) over concentrations from 2.5 to 20 ng/mL and 20 to 320 ng/mL for both MCPT and HCPT. The method had an accuracy of 92.74% to 112.76%, and the intra- and inter-day precision (RSD%) were 11.85% or less for MCPT and HCPT. The stability data showed no significant degradation occurred under the experimental conditions.
    CONCLUSIONS:
    This method was successfully applied to the tissue distribution study of MCPT and its metabolite HCPT in liver tissue samples after intravenous administration.
    10-Methoxycamptothecin Description
    Source: The barks of Camptotheca acuminata Decne
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
