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.

Efficient total synthesis and biological activities of 6-deoxyisojacareubin.[Pubmed:
23519477 ]
METHODS AND RESULTS:
6-Deoxyisojacareubin was directly synthesized in a six-step route with an overall yield of about 20%. In this route, the excellent site selectivity of this Claisen rearrangement-cyclization reaction cascade was achieved by inserting a bulky p-tosyl group into the free 1-OH, and in the last step, some efficient demethylation methods were explored. Furthermore, all synthesized intermediates including 6-Deoxyisojacareubin were evaluated for their inhibitory activity against the QGY-7703 cell line.
CONCLUSIONS:
Of these, compound 1 and 6-Deoxyisojacareubin showed moderate activities with IC50 values of 39.61 and 9.65 μM, respectively, when compared to the positive control 5-fluorouracil with an IC50 value of 11.24 μM. Further investigation using non-radioactive detection of protein kinase C (PKC) suggested that these two compounds possessed potency in the inhibition of PKC.

A new pyranoxanthone from Garcinia nervosa.[Pubmed:
28412841]
METHODS AND RESULTS:
Phytochemical studies on the stem bark of Garcinia nervosa has resulted in the discovery of one new pyranoxanthone derivative, garner xanthone (1) and five other compounds, 1,5-dihydroxyxanthone (2), 6-Deoxyisojacareubin (3), 12b-hydroxy-des-D-garcigerrin A (4) stigmasterol (5), and β-sitosterol (6).
The structures of these compounds were elucidated with the aid of spectroscopic techniques, such as NMR and MS.
CONCLUSIONS:
The crude extracts of the plant were assessed for their antimicrobial activity.
