Preliminary screening test of modulators for multidrug resistance with 400 medicinal plants was carried out by using human multidrug resistance cell line, KB-V1. Among active medicinal plants, the unripe fruits of Evodia officinalis showed a potent modulating activity of MDR. From MeOH extract of this plant, we isolated two indole alkaloids, rutaecarpine (1) and evodiamine (2), by repeated silicagel column chromatography. Rutaecarpine increased the cytotoxicities of vinblastine and taxol against multidrug resistance cells, but evodiamine showed no modulating activity in spite of its potent cytotoxic activities.

A series of substituted rutaecarpines were prepared by employing Fischer indole synthesis as key step and their inhibitory activities on COX-1 and 2 as well as selectivity on COX-2 were evaluated. The compounds with a methanesulfonyl and a bromo group at C10 showed promising inhibitory activity ($IC_{50}$ = 0.27, 0.35 $\mu$M, respectively) with selectivity.

A series of rutaecarpine homologues were prepared from 2,3-polymethylene-4(3H-quinazolinones in 4 steps [i) PhCHO/Ac$_2$O, ⅱ) O,$_3$ ⅲ) PhNHNH$_2$HCl, and ⅳ) PPA], in which dihedral angles of the two planar aromatic rings (indole and 4(3H)-quinazolinone) were controlled in a regular fashion. Their inhibitory activities on COX-1 and COX-2 were evaluated to show that the inhibitory activities were increased with the increase of the length of methylene unit while selectivities on COX-2 decreased leading a loss in trimethylene bridged system.

Evodiae Fructus is the dried unripe fruit of Evodia rutaecarpa, and has traditionally been used for treating stomachache and diarrhea. Evodiamine and rutaecarpine, the major biologically active compounds of Evodiae Fructus, are reported to have anti-oxidative and anti-inflammatory effects, as well as inhibit proliferation and metastasis of various cancer cells. The current study investigates the anti-oxidative and anti-cancer effects of the Evodiae Fructus extract, considering varying concentrations of methanol extraction (40, 80, and 95%). High contents of total phenolic compounds were determined in the order of extracts 80, 95, and 40%. Evaluating contents of the 95, 80, and 40% extracts revealed 36.77, 7.29, and 1.86 ㎍/mg evodiamine, respectively, and 53.02, 17.16, and 3.79 ㎍/mg rutaecarpine, respectively, with the highest content of both compounds obtained in the 95% extract. DPPH radical scavenging activity was observed to be inversely proportional to the contents of total phenolic compounds, with decreasing SC₅₀ values obtained in the order 80, 95, and 40% extract. The 95 and 80% extracts exerted toxicity to AGS gastric cancer cells, but the 40% extract was non-toxic. Evodiamine is a known anti-cancer agent, and could be responsible for the observed toxicity. Cleavage of PARP, and Caspase-3, -7, -8 and -9 was observed in the 95% extract-treated AGS cells, indicating that cell toxicity exerted by the 95% extract could be attributed to apoptosis.

Objectives: This study was designed to examine immuno-modulatory effects of Evodia Rutaecarpine by activating innate immune system and inhibiting inflammation. Methods: First, Cell cytotoxicity was examined with 4T1 breast carcinoma and TG-induced macrophage. To investigate activating innate immune system of Evodiamine Rutacarpine Extract (ERE) on macrophage, we tested tumor necrosis factor-alpha (TNF-α), interleukin-12 (IL-12), and interleukin-6 (IL-6). In addition, TNF-α and nitric oxide (NO) induced by lipopolysaccharide (LPS) were measured after treating with ERE to observe innate immune modulating effect of ERE on RAW 264.7 cell. Also, mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) were examined by western blot analysis. Results: In cytotoxicity analysis, ERE significantly affected tumor cell growth above specific concentration. Also, ERE significantly affected macrophage growth above specific concetration. As compared with the control group, the production of TNF-α, IL-12 and IL-6 were increased in TG-induced macrophage. As compared with the control group, TNF-α and IL-6 were significantly up-regulated in RAW 264.7 cell. The expression of TNF-α and NO induced by LPS after treating ERE was significantly decreased compared with control group. In addition, We observed ERE inhibited the phosphorylation levels of p-extracellular signal-regulated kinase (p-ERK), p-Jun N-terminal kinase (p-JNK), and p-p38 in western blotting by treating ERE on RAW 264.7 cell. Conclusions: ERE seems to have considerable impact on the anti-cancer effect by activation of innate immune system and inflammation control.

본 연구는 황백에 함유되어 있는 주요 화합물인 berberine, palmatine, limonin 및 rutaecarpine의 CYP2D6 및 p-glycoprotein 활성에 대한 저해정도를 탐색함으로써, 황백을 다른 양약과 병용시 약물상호작용을 유발할 수 있는 가능성을 평가하고자 하였다. 인체 간 마이크로좀 시료에 CYP2D6 동효소의 기질약물인 dextromethorphan과 NADPH 재생성계 및 저해제 ($200{\mu}M$)를 첨가한 후 반응시켜 생성된 대사물을 LC/MS/MS를 이용하여 정량하여 CYP2D6 동효소 활성의 변화를 평가하였다. 또한 약물수송단백인 p-glycoprotein의 활성은 L-MDR1 세포주를 이용한 calcein AM 축적 실험을 통하여 평가하였다. 그 결과 식물 알카로이드인 berberine에서 강력한 CYP2D6 활성 저해능을 관찰하였으며, 저해 효과는 농도 의존적으로 증가하였으며, mechanism-based 저해 기전을 나타내었다. 그러나 limonine과 rutaecarpine은 CYP2D6 저해 활성을 보이지 않았고, p-glycoprotein 기능에 대해서는 평가한 어떤 화합물도 저해 활성을 나타내지 않았다. 황백의 주요 성분인 berberine의 CYP2D6 활성 저해능을 고려할 때, 황백을 CYP2D6 기질약제와 병용시 약물상호작용을 유발할 가능성을 보여준다. 이러한 황백의 CYP2D6를 매개로한 임상적인 약물상호작용 가능성은 임상시험을 통하여 추가적인 검정이 필요할 것으로 사료된다.

The MeOH extract of Evodiae Fructus exhibited a significant inhibition on the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), in a dose dependent manner, respectively. The extensive bioactivity-guided fractionation process with the MeOH extract finally isolated four compounds, as rutaecarpine (1), evodiamine (2), limonin (3) and dehydroevodiamine (4). Among them, compound 2 exhibited specific inhibitory activity on BChE with the $IC_{50}$ values 1.7 ${\mu}g/ml$, whereas compound 4 showed the potent inhibition upon both AChE and BChE.

Abstract - The Evodiae Fructus is known for containing a number of indolquinazoline and quinoline type alkaloids. Evodiamine, evocarpine and rutaecarpine are the major constituents of alkaloids. These alkaloids were isolated and determined by forming complex compounds from Evodiae Fructus in O-Su-You-Tang. For the determination of these alkaloids, a new spectrophotometric method was developed with a simple and selective sample clean-up using thiocyanatocobaltate[II] compIεx compound ion. The absorbance of alkaloidal complex compounds in 1,2-dichloroethane solution was measured at 625 nm. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in O-Su-You-Tang.

The fruit of Evodia officinalis (Rutaceae) is known for containing a number of indoloquinazoline and quinoline type alkaloids. Evodiamine, evocarpine and rutaecarpine are the major constituents of Evodiae Fructus. These alkaloids were isolated and determined by forming complex compounds from Evodiea Fructus. For the determination of these alkaloids, a new spectrophotometric method was developed with a simple and selective sample clean-up using thiocyanatocobaltate [II] complex ion. The absorbance of alkaloidal complex in 1.2-dichloroethane solution was measured at 625 nm. A calibration curve for the alkaloids isolated from Evodia Fruit was linear over the concentration range of $1.0{\sim}6.0\;mg/ml$. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in Evodiae Fructus.
