|Synthesis of triterpenoid triazine derivatives from allobetulone and betulonic acid with biological activities.[Pubmed: 24844757]|
|The synthetic transformation and modification of natural products with the aim to improve the biological properties is an area of current interest. The triterpenoids betulin and betulinic acid are very abundant in nature and now are commercially available.
METHODS AND RESULTS:
In our study, starting from betulin and betulinic acid, we obtained allobetulone and Betulonic acid in a few synthetic steps. The ketone function at the A-ring was used as the starting point for the synthesis of a series of 1,2,4-triazine-fused triterpenoids. The alkylation and Liebeskind-Srogl coupling were used for further substitution of 1,2,4-triazines, and the intramolecular hetero Diels-Alder reaction leads to interesting fused thienopyridine derivatives. All new compounds were tested for their cytostatic activities against murine leukemia L1210, human cervix carcinoma HeLa and human lymphoblast CEM tumor cells.
The results show that some triterpenoid triazine Betulonic acid derivatives have a promising cytostatic activity in vitro and could be used as potential leads for the development of new type of anti-cancer agents. Several compounds were also endowed with anti-HCMV activity in the low micromolar range.

|Antiviral activity of betulin, betulinic and betulonic acids against some enveloped and non-enveloped viruses.[Pubmed: 12837369]|
METHODS AND RESULTS:
Antiviral properties of betulin, betulinic and Betulonic acids were investigated in cell cultures infected with herpes simplex type I, influenza FPV/Rostock and ECHO 6 viruses.
All studied triterpenes were active against herpes simplex virus. Betulin and especially betulinic acid also suppressed ECHO 6 virus reproduction.

|Efficient synthesis of the first betulonic acid-acetylene hybrids and their hepatoprotective and anti-inflammatory activity.[Pubmed: 19524443 ]|
|The Sonogashira reaction can be applied for the preparation of acetylenic derivatives of Betulonic acid where the triterpenoid moiety can serve as either the halo- or the acetylenic component. This reaction opened access to the first derivatives of Betulonic acid containing either the arylethynyl (C[triple bond]C-Ar(Het) or the ethynyl (C[triple bond]CH) moieties. From the fundamental perspective, this work illustrates the possibility of selective Pd-catalyzed cross-coupling at terminal acetylenes in the presence of a terminal alkene.
METHODS AND RESULTS:
Hepatoprotective and anti-inflammatory properties of selected acetylenic derivatives of Betulonic acid were investigated using the CCl4-induced hepatitis and carrageenan-induced edema models, respectively.
Betulonic acid Description
||The branches of Eucalyptus globulus Labill.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||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: email@example.com
||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.

|Biotransformation of betulinic and betulonic acids by fungi.[Pubmed: 17258248]|
|Betulinic acid (1), a triterpenoid found in many plant species, has attracted attention due to its important pharmacological properties, such as anti-cancer and anti-HIV activities.
The closely related, Betulonic acid (2) also has similar properties. In order to obtain derivatives potentially useful for detailed pharmacological studies, both compounds were submitted to incubations with selected microorganisms.
METHODS AND RESULTS:
In this work, both were individually metabolized by the fungi Arthrobotrys, Chaetophoma and Dematium, isolated from the bark of Platanus orientalis as well as with Colletotrichum, obtained from corn leaves; such fungal transformations are quite rare in the scientific literature. Biotransformations with Arthrobotrys converted Betulonic acid (2) into 3-oxo-7beta-hydroxylup-20(29)-en-28-oic acid (3), 3-oxo-7beta,15alpha-dihydroxylup-20(29)-en-28-oic acid (4) and 3-oxo-7beta,30-dihydroxylup-20(29)-en-28-oic acid (5); Colletotrichum converted betulinic acid (1) into 3-oxo-15alpha-hydroxylup-20(29)-en-28-oic (6) acid whereas Betulonic acid (2) was converted into the same product and 3-oxo-7beta,15alpha-dihydroxylup-20(29)-en-28-oic acid (4); Chaetophoma converted Betulonic acid (2) into 3-oxo-25-hydroxylup-20(29)-en-28-oic acid (7) and both Chaetophoma and Dematium converted betulinic acid (1) into Betulonic acid (2).
Those fungi, therefore, are useful for mild, selective oxidations of lupane substrates at positions C-3, C-7, C-15, C-25 and C-30.
