| Planta Med. 2000 Aug;66(6):564-7. | | Antifungal, antimitotic and anti-HIV-1 agents from the roots of Wikstroemia indica.[Pubmed: 10985087] |
METHODS AND RESULTS:
With guidance of Pyricularia oryzae bioassay, daphnoretin (1), (+)-nortrachelogenin (2), genkwanol A (3), Wikstrol A (4), wikstrol B (5) and daphnodorin B (6) were isolated from the roots of Wikstroemia indica. Compounds 1-6 induced morphological deformation of P. oryzae mycelia with MMDC values of 68.4 +/- 1.3, 31.3 +/- 1.8, 45.8 +/- 0.5, 70.1 +/- 2.4, 52.3 +/- 0.9 and 73.7 +/- 1.6 microM, respectively. Compounds 3-6 showed moderate activity against microtubule polymerization with IC50 values of 112 +/- 4, 131 +/- 3, 184 +/- 6 and 142 +/- 2 microM in vitro, respectively. Compounds 2, 3, 5 and 6 were moderately active against HIV-1 in vitro.
CONCLUSIONS:
The findings of bioactivity of 1-6 support the antifungus, antimitosis and anti-HIV-1 uses for W. indica roots. | | Pharmaceutical Biology, 2005, 43(1):12-14. | | Aldose Reductase Inhibitors from Stellera chamaejasme.[Reference: WebLink] |
METHODS AND RESULTS:
Six biflavonoids (chamaejasmin, 7-methoxyneochamaejasmin, 7-methoxychamaejasmin, chamaejasmenin B, chamaechromone, Wikstrol A) from Stellera chamaejasme. L. have been assayed to show good aldose reductase inhibiting activity.
CONCLUSIONS:
These compounds may be useful to improve diabetic complications such as neuropathy, cataract formation, neophropathy, and retinopathy. |
