| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Antiinflammatory activities of flavonoids and a triterpene caffeate isolated from Bauhinia variegata.[Pubmed:18384188]
Phytother Res. 2008 Jul;22(7):957-62.
In the continuing search for novel antiinflammatory agents, six flavonoids, namely kaempferol (1), Ombuin (2), kaempferol 7,4'-dimethyl ether 3-O-beta-D-glucopyranoside (3), kaempferol 3-O-beta-D-glucopyranoside (4), isorhamnetin 3-O-beta-D-glucopyranoside (5) and hesperidin (6), together with one triterpene caffeate, 3beta-trans-(3,4-dihydroxycinnamoyloxy)olean-12-en-28-oic acid (7) were isolated from the non-woody aerial parts of Bauhinia variegata. Compounds 1-7 were evaluated as inhibitors of some macrophage functions involved in the inflammatory process. These seven compounds significantly and dose dependently inhibited lipopolysaccharide (LPS) and interferon (IFN)-gamma induced nitric oxide (NO), and cytokines [tumor necrosis factor (TNF)-alpha and interleukin (IL)-12]. The concentration causing a 50% inhibition (IC50) of NO, TNF-alpha and IL-12 production by compounds 1, 2 and 7 was approximately 30, 50 and 10 microM, respectively, while at 50, 200 and 40 microM compounds 3, 4, and 5, 6 showed 15-30% inhibition, respectively. On the other hand, compounds 3 and 7 showed no inhibitory effect, while compounds 1, 4-6 reduced by around 10-30% the synthesis of NO by macrophages, when inducible NO synthase was already expressed with LPS/IFN-gamma for 24 h. These experimental findings lend pharmacological support to the suggested folkloric uses of the plant B. variegata in the management of inflammatory conditions.
Licochalcone A: an inducer of cell differentiation and cytotoxic agent from Pogostemon cablin.[Pubmed:9690352]
Planta Med. 1998 Jun;64(5):464-6.
Licochalcone A (1), Ombuin (2), and 5,7-dihydroxy-3',4'-dimethoxyflavanone (3) were isolated from the aerial parts of Pogostemon cablin by cytotoxicity-guided fractionation. Compound 1 showed in vitro cytotoxicity and Pl-PLC gamma 1 inhibition activity. Treatment of promyelocytic leukemia cells (HL-60) with compound 1 induced terminal differentiation with the generation of monocyte using nonspecific acid esterase assay.
