In the present study, we investigated the effect of asiatic acid (the aglycon of asiaticoside) and asiaticoside isolated from the leaves of Centella asiatica (Umbelliferae) on LPS-induced NO and PGE(2) production in RAW 264.7 macrophage cells. Asiatic acid more potently inhibited LPS-induced NO and PGE(2) production than asiaticoside. Consistent with these(More)
Although mounting evidence indicates the involvement of galectin-3 in cancer progression and metastasis, the underlying molecular mechanisms remain largely unknown. In this study, we investigated the effect and possible mechanism of galectin-3 on the migration and invasion of B16F10, a metastatic melanoma cell line, in which galectin-3 and matrix(More)
In the present study, we developed a method coupling liquid-liquid extraction (LLE) to high-performance liquid chromatography (HPLC) with positive ion electrospray ionization tandem mass spectrometry (ESI-MS/MS) to determine zaltoprofen levels in human plasma, using enalapril as internal standard (IS). The high sensitivity and specificity of MS/MS detection(More)
Previously, the authors demonstrated that the triterpenoid glycoside niga-ichigoside F₁ (NIF₁) and its aglycone 23-hydroxytormentic acid (23-HTA) isolated from the unripe fruits of Rubus coreanus (Rosaceae) ameliorate cisplatin-induced toxicity in renal epithelial LLC-PK₁ cells. In the present study, the nephroprotective effects of NIF₁ and 23-HTA were(More)
A simple and specific method using a one-step liquid-liquid extraction (LLE) with butyl acetate followed by high performance liquid chromatography (HPLC) coupled with positive ion electrospray ionization tandem mass spectrometry (ESI-MS/MS) detection was developed for the determination of etodolac in human plasma, using indomethacin as an internal standard(More)
Fast gas chromatography combined with surface acoustic wave sensor (GC/SAW) has been applied for the detection of volatile aroma compounds emanated from thymus medicinal plants such as T. quinquecostotus (Jeju and Mt. Gaya in South Korea), T. quinquecostotus var. japonica (Ulreung island in South Korea), T. mongolicus (Northeastern Asia), and T. serpyllum(More)
A simple method using a one-step liquid-liquid extraction (LLE) with methyl-t-butyl ether (MTBE) followed by high-performance liquid chromatography (HPLC) with negative-ion electrospray ionization tandem mass spectrometric (ESI-MS/MS) detection was developed for the determination of cilnidipine in human plasma using benidipine as an internal standard (IS).(More)
