Inhibition of ectopic calcification is a critical function of any internal medical therapy for CAS disease.
The aim of the present study was to investigate the inhibitory effects of several derivatives of evocarpine, methanolic extracts from the fruits of Evodia rutaecarpa Bentham (Japanese name: Go-Shu-Yu) on the high phosphate-induced calcification of human aortic valve interstitial cells (HAVICs) obtained from patients with CAS.
METHODS AND RESULTS:
High phosphate (3.2 mM) concentrations significantly increased the calcification of HAVICs after 7 days of culture. This calcification was completely inhibited in the presence of sodium phosphonoformate (PFA), a selective inhibitor of the type III sodium-dependent phosphate cotransporter (PiT-1). PiT-1 contributes to phosphate uptake, resulting in calcification. 1-Methyl-2-undecyl-4(1H)-quinolone (1-Methyl-2-undecylquinolin-4(1H)-one,MUQ; 30-300 nM), but not evocarpine or its derivatives dihydroevocarpine and 1-methyl-2-nonyl-4(1H)-quinolone, inhibited the high phosphate-induced HAVICs calcification in a concentration-dependent manner. Although all of the evocarpine derivatives attenuated alkaline phosphatase activity, only MUQ also decreased PiT-1 gene expression with cellular PiT-1 protein diminution.
CONCLUSIONS:
These results suggest that MUQ mitigated high phosphate-induced HAVICs calcification by inhibiting PiT-1 gene expression. | | J Anal Methods Chem. 2013;2013:827361. | | Simultaneous Quantification of Limonin, Two Indolequinazoline Alkaloids, and Four Quinolone Alkaloids in Evodia rutaecarpa (Juss.) Benth by HPLC-DAD Method.[Pubmed: 23738236 ] |
METHODS AND RESULTS:
A simple and efficient HPLC-DAD (225 nm) method was developed and validated for the simultaneous determination of limonin and six key alkaloids (evodiamine, rutaecarpine, 1-methyl-2-undecyl-4(1H)-quinolone(1-Methyl-2-undecylquinolin-4(1H)-one), evocarpine, 1-methy-2-[(6Z,9Z)]-6,9-pentadecadienyl-4-(1H)-quinolone, and dihydroevocarpine) in Evodia rutaecarpa (Juss.) Benth, which has been widely used as one of the Traditional Chinese Medicines.
CONCLUSIONS:
This study indicated that the quality control of E. rutaecarpa could be simplified to the measurement of four constituents, and that limonin, 1-methyl-2-undecyl-4(1H)-quinolone(1-Methyl-2-undecylquinolin-4(1H)-one), and dihydroevocarpine should also be served as the chemical markers together with evodiamine for the quality control of Evodia rutaecarpa (Juss.) Benth. | | Planta Medica,2012,78(11):1202-3. | | Studies on the chemical constituents of Evodia rutaecarpa and Evodia rutaecarpa passed with Liquorice and biological activities[Reference: WebLink] |
METHODS AND RESULTS:
17 indole quinoline alkaloids, 8 limonins, 7 flavonoids, 7 triterpenoids and 11 other compounds were obtained from E. rutaecarpa and E. rutaecarpa passed with Liquorice. 6 of them are new compounds. About 19 compounds were tested by replanting tumor to mice, angioma of zebrafish model for antiangiogenic drug screening and human tumor cells in vitro.
CONCLUSIONS:
Thus compounds evodiagenine (2), evodialimonin (3), rhetsinine (4), dehydroevodiamine (5), wuchuyuamide I (7) and 1-methyl-2-undecyl-4(1H)-quinolone (1-Methyl-2-undecylquinolin-4(1H)-one,8) showed moderate activity against human tumor cells, dievodiamine (1) and evodiamine (6) showed good activity. The inhibitory rate of 4 on sarcoma S180 was 57.78% at the dose of 5–10mg/kg·d in vivo. Moreover, the inhibition of the active selectivity of cycloxygenase 1 and 4 showed a stronger effect. |
