    3-Oxo-21alpha-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone Description
    Source: The stem barks of Aphanamixis grandifolia.
    Biological Activity or Inhibitors: 1. 3-Oxo-21alpha-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone may show cytotoxic activities against five tumor cell lines (MCF-7, HeLa, HepG2, SGC-7901 and BGC-823).
    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.

    Cytotoxic tirucallane C26 triterpenoids from the stem barks of Aphanamixis grandifolia.[Pubmed: 20851441 ]
    Five tirucallane type C(26) triterpenoids, accompanied by two known compounds, 3α-hydroxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone and 3-oxo-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone, were isolated from the stem barks of Aphanamixis grandifolia. Their structures were established mainly by means of a combination of 1D and 2D NMR spectroscopic and mass spectrometry techniques as 3α-hydroxyl-21α-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone, 3α-hydroxy-21β-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone,3-Oxo-21alpha-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone, 3-oxo-21β-methoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone, and 3-oxo-21α-ethoxy-24,25,26,27-tetranortirucall-7-ene-23(21)-lactone. All isolates were in vitro evaluated for their cytotoxic activities against five tumor cell lines (MCF-7, HeLa, HepG2, SGC-7901 and BGC-823).
