Ganghwaljetongyeum (GHJTY) is a complex herbal decoction comprising 18 plants; it is used to treat arthritis. In order to develop a new anti-arthritic herbal medication, we selected 5 out of 18 GHJTY plants by using bioinformatics analysis. The new medication, called ChondroT, comprised water extracts of Osterici Radix, Lonicerae Folium, Angelicae Gigantis Radix, Clematidis Radix, and Phellodendri Cortex. This study was designed to investigate its chondroprotective and anti-inflammatory effects to develop an anti-arthritic herb medicine. ChondroT was validated using a convenient and accurate high-performance liquid chromatography. photodiode array (HPLC-PDA) detection method for simultaneous determination of its seven reference components. The concentrations of the seven marker constituents were in the range of 0.81-5.46 mg/g. The chondroprotective effects were evaluated based on SW1353 chondrocytes and matrix metalloproteinase 1 (MMP1) expression. In addition, the anti-inflammatory effects of ChondroT were studied by Western blotting of pro-inflammatory enzymes and by enzyme-linked immunosorbent assay (ELISA) of inflammatory mediators in lipopolysaccharides (LPS)-induced RAW264.7 cells. ChondroT enhanced the growth of SW1353 chondrocytes and also significantly inhibited IL-1β-induced MMP-1 expression. However, ChondroT did not show any effects on the growth of HeLa and RAW264.7 cells. The expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) was induced by LPS in RAW264.7 cells, which was significantly decreased by pre-treatment with ChondroT. In addition, ChondroT reduced the activation of NF-κB and production of inflammatory mediators, such as IL-1β, IL-6, PGE2, and nitric oxide (NO) in LPS-induced RAW264.7 cells. These results show that ChondroT exerted a chondroprotective effect and demonstrated multi-target mechanisms related to inflammation and arthritis. In addition, the suppressive effect was greater than that exhibited by GHJTY, suggesting that ChondroT, a new complex herbal medication, has therapeutic potential for the treatment of arthritis.

Background: Astragali radix (A) and Lithospermi radix (L) have long been used as traditional medicines due to their known anti-inflammatory effects. This study aimed at evaluating, their optimal mixing ratio and their functional compounds by investigating the inhibitory effects of mixed extracts of A and L and their active compounds on matrix metalloproteinases (MMPs). Methods and Results: A and L extracts were obtained by extraction at $80^{\circ}C$ using 50% and 70% fermented alcohol, respectively, and then mixed at a ratio of 5 : 5, 6 : 4, 7 : 3 and 8 : 2 (w/w). The activities of MMP-1, MMP-3, and MMP-13 were evaluated in interleukin-1beta ($IL-1{\beta}$)-induced SW1353 cells. The extract mixtures showed synergistic inhibitory effects on MMP-3 and MMP-13, higher than the effects of the individual A and L extracts. The 7 : 3 mixture (ALM16) showed the most effective MMPs inhibitory activity, while among the active ingredients, calycosin-7-O-${\beta}$-D-glucoside and lithospermic acid exhibited excellent MMPs inhibitory activity. Additionally, an HPLC method was established for simultaneous quantification of the effective components of the extract mixtures, and validated by measuring the linearity, precision and accuracy of the limit of detection (LOD) and limit of quantification (LOQ). Conclusions: ALM16 showed the most effective MMPs inhibitory activity. Calycosin-O-${\beta}$-D-glucoside, calycosin and lithospermic acid were identified as useful candidates, as they were the major functional compounds in the MMP inhibitory activity. Summarily, ALM16 might be a highly effective in osteoarthritis management, owing to its because it exhibits a protective effect on cartilage via excellent inhibition of MMPs.

This study investigates the effect of supercritical fluid extract (CMPB803-C) of Lithospermum erythrorhizon, shikonin and acetylshikonin isolated from Lithospermum erythrorhizon on IL-$1{\beta}$-induced chondrocytes and monosodium iodoacetate (MIA)-induced osteoarthritis in rat. Shikonin ($50{\mu}m$) and acetylshikonin ($3{\mu}M$) treatment reduced significantly the mRNA expression and enzyme activity of matrix metalloproteinase (MMP)-1, -3 and -13 in IL-$1{\beta}$-induced SW1353 chondrosarcoma cells. The chondro-protective effects of CMPB803-C and acetylshikonin were than analyzed in a rat OA model using a single intra-articular injection of MIA (1mg) in the right knee joint. CMPB803-C (200mg/kg) or acetylshikonin (5mg/kg) was orally administered daily for two weeks starting after 1 week of MIA injection. In the histological observation, CMPB803-C and acetylshikonin clearly improved OA lesions being comparable to or better that control group. Our results demonstrated that CMPB803-C and acetylshikonin as active compound of Lithospermum erythrorhizon have a strong chondro-protective effect in OA rats, which likely attributes to its anti-inflammatory activity and inhibition of MMPs production.

Background: The present study was designed to prepare and find the optimum active preparation or fraction from Korea Red Ginseng inhibiting matrix metalloproteinase-13 (MMP-13) expression, because MMP-13 is a pivotal enzyme to degrade the collagen matrix of the joint cartilage. Methods: From total red ginseng ethanol extract, n-BuOH fraction (total ginsenoside-enriched fraction), ginsenoside diol-type-enriched fraction (GDF), and ginsenoside triol-type-enriched fraction (GTF) were prepared, and ginsenoside diol type-/F4-enriched fraction (GDF/F4) was obtained from Panax ginseng leaf extract. Results: The n-BuOH fraction, GDF, and GDF/F4 clearly inhibited MMP-13 expression compared to interleukin-$1{\beta}$-treated SW1353 cells (human chondrosarcoma), whereas the total extract and ginsenoside diol-type-enriched fraction did not. In particular, GDF/F4, the most effective inhibitor, blocked the activation of p38 mitogen-activated protein kinase (p38 MAPK), c-Jun-activated protein kinase (JNK), and signal transducer and activator of transcription-1/2 (STAT-1/2) among the signal transcription pathways involved. Further, GDF/F4 also inhibited the glycosaminoglycan release from interleukin-$1{\alpha}$-treated rabbit cartilage culture (30.6% inhibition at $30{\mu}g/mL$). Conclusion: Some preparations from Korean Red Ginseng and ginseng leaves, particularly GDF/F4, may possess the protective activity against cartilage degradation in joint disorders, and may have potential as new therapeutic agents.

NUC1 (Nutraceutical compound 1) is an ethanol extract composed of a formulation based on medicinal herbs traditionally used for the treatment of arthritis in Korea and China. This study investigated the therapeutic effects of NUC1 on osteoarthritis (OA). The protective effect of NUC1 on OA was tested in a rabbit model of collagenase-induced arthritis (CIA) for 4 weeks. Results were compared among four groups (n = 9 per group): the normal group (untreated), the CIA group (vehicle control), the NUC1 group (CIA rabbits treated with 200 mg/kg NUC1), and the JOINS group (positive control, CIA rabbits treated with 200 mg/kg JOINS tablet). NUC1 significantly inhibited NO production (p < 0.05 at 125 ㎍/ml, p < 0.01 at 250 ㎍/ml, and p < 0.001 at 500 ㎍/ml) and iNOS expression in macrophages, in a concentration-dependent manner. NUC1 also inhibited the release and protein expression of MMP-1, 3, and 13, in TNF-α-induced chondrosarcoma cells in a concentration-dependent manner. In vivo, the MMP-1 and MMP-3 levels in synovial fluids were significantly (p < 0.05) lower in NUC1 group (77.50 ± 20.56 and 22.50 ± 7.39 pg/ml, respectively) than in the CIA group (148.33 ± 68.58 and 77.50 ± 20.46 pg/ml, respectively). Also, in histopathological, NUC1 ameliorated articular cartilage damage in OA by increasing the abundance of chondrocytes and proteoglycan in the articular cartilage. Thus, NUC1 showed promise as a potential therapeutic agent, and it can be generalized to a broader study population in different OA animal models.

노화에 따른 퇴행성관절염은 삶의 질을 저하시키는 가장 큰 병리학적 현상 중의 하나이다. 오미자 열매(Schisandrae Fructus)는 오랫동안 전통의학에서 여러 가지 만성질환 치료를 위해 널리 사용되어 왔다. 오미자 추출물이 SW1353 인간 연골세포에서 $IL-1{\beta}$에 의해 유발된 염증 반응을 감소시키는 것으로 최근 보고된 바 있으나, primary culture된 연골세포 및 동물 모델에서의 퇴행성관절염에 대한 보호 및 치료 잠재력은 여전히 명확하지 않다. 따라서 본 연구에서는 $IL-1{\beta}$에 의해 유도된 primary culture된 쥐의 연골세포와 MIA에 의해 유도된 골관절염에 대한 matrix metalloproteinases (MMPs)의 활성에 미치는 오미자 에탄올 추출물의 영향을 조사하였다. 오미자 추출물 처리는 $IL-1{\beta}$로 유도된 연골세포에서 MMP-1, -3 및 -13의 mRNA 발현 및 효소 활성을 유의하게 감소시켰다. 또한 오미자 추출물은 MIA에 의해 증가된 MMP-1 및 -3의 발현을 유의적으로 억제시켰다. 따라서 오미자 추출물은 퇴행성관절염 예방과 치료를 위한 기능성 소재로서의 잠재적 가능성이 있음을 알 수 있었다.
