Abstract
Demethyleneberberine is an active component extracted from the Chinese herbal drug Cortex Phellodendri. It is also a metabolite of berberine in animals and humans. However, the pharmacokinetics, tissue distribution and excretion of demethyleneberberine have not been reported. The present study aimed to investigate the pharmacokinetic parameters of demethyleneberberine by applying high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). After intragastric administration of demethyleneberberine in rats and mice, the pharmacokinetics, tissue distribution and excretion of demethyleneberberine were comparatively studied for the first time. The plasma concentration of demethyleneberberine reached its peak within 5 min after intragastric administration in both rats and mice. Furthermore, its bioavailability was comparable, ranging from 4.47% to 5.94%, higher than that of berberine. The total excretion of demethyleneberberine in the urine, feces and bile was 7.28~9.77%. These findings provide valuable insights into the pharmacological and clinical research on demethyleneberberine.

Abstract
Introduction Phellodendron amurense Rupr. contains rich alkaloids, which have been extensively applied in clinical treatments for their various biological activities. However, detailed microscopic distribution and roles of such alkaloids in P. amurense stem still need to be clarified. Methods In this study, the distribution of eight alkaloids in the transverse surface of freeze-fixed P. amurense stems in fall and summer has been visualized by cryo-time-of-flight secondary ion mass spectrometry and scanning electron microscopy (cryo-TOF-SIMS/SEM), which was found in living tissues with relative contents of different alkaloids varying with the position. In addition, the contents of these alkaloids quantified by high-performance liquid chromatography (HPLC) analysis suggested the seasonal variation from fall to the following summer. Results and discussion Distribution of eight alkaloids in the freeze-fixed stems of P. amurense from fall and summer seasons has been visualized and assigned into specific living tissues, with relative contents varying in different positions with seasons, which suggested their possible roles in the physiological processes of the plant itself or plant responding to changes in the surrounding conditions. Conclusion This study provided a significant basis for further discussion of the genes or enzymes involved in these processes, which will contribute to investigating biosynthetic pathways and specific in planta roles of alkaloids.

Hou PW, Liu SC, Tsay GJ, Chang YS, Huang HC, Tang CH, Chang HH. High-dose Tiger-Gian formula protects the knee joint from surgically induced osteoarthritis in rats. Int J Rheum Dis 2023; 26:316-326. [PMID: 36401840 DOI: 10.1111/1756-185x.14497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 10/16/2022] [Accepted: 11/02/2022] [Indexed: 11/21/2022]
Abstract
AIM Although the Tiger-Gian formula (TGF) has proven clinically effective at improving the symptoms of knee osteoarthritis (KOA), the pharmacological effects and underlying mechanisms of TGF have not been examined in any animal model. This study assessed the effects of TGF in male Sprague-Dawley rats with anterior cruciate ligament transection (ACLT) -induced KOA. METHODS Thirty rats underwent ACLT surgery and were assigned to either the control group, ACLT alone, ACLT + low-dose TGF (1000 mg/kg), ACLT + high-dose TGF (3000 mg/kg), or ACLT + celecoxib (30 mg/kg). All rats were subjected to micro-computed tomography (micro-CT), weight-bearing behavioral testing, and histological inspections of the knee joint for evidence of structural changes in articular bone, cartilage and synovium. RESULTS After 6 weeks, force discrepancies in weight-bearing distribution between the normal hind and postoperative limbs revealed superiority with high-dose TGF (18.00 ± 5.93 g) and celecoxib (18.68 ± 5.29 g) versus both ACLT alone (41.29 ± 7.06 g) and low-dose TGF (37.00 ± 7.40 g). Micro-CT images revealed that high-dose TGF and celecoxib similarly improved subchondral bone architecture, protected articular cartilage after ACLT, and downregulated proinflammatory cytokines interleukin-1β and tumor necrosis factor-α in the cartilage and synovial sections. CONCLUSION High-dose TGF induced the smallest amount of KOA-associated bone loss. Anti-inflammatory, anti-oxidative, and immunomodulatory effects of TGF were accompanied by reductions in proinflammatory cytokines and improvements in pain and function. TGF-induced anti-osteoporotic activity and inhibition of cartilage degradation were reflected by micro-CT and histological analysis. The findings help to explain how TGF alleviates symptoms of KOA.

Abstract
Dietary supplement and personal care products aiming to provide protection from air pollution have been of great interest for decades. Epidemiology demonstrated that PM10 and PM2.5 particulate matter (PM) are an actual threat to public health worldwide, but the detailed processes of how these particles attack the cells are not fully understood. Here, we report that the measurement of intracellular calcium concentration ([Ca2+]i) using human respiratory or skin cells can illustrate pollutant challenges by triggering Ca2+ influx in these cells. This signal was generated by proteinase-activated receptor-2 (PAR-2), confirmed by competition analyses, and Phellodendron amurense bark extract (PAE), a traditional medicine, was able to control the response and expression of PAR-2. Increase in proinflammatory cytokines and decrease in cell adhesion components could suggest a severe damage status by air pollutants and protection by PAE. Finally, we identified 4-O-feruloylquinic acid (FQA), an active compound of PAE, showing the same effects on Ca2+ influx and PAR-2 regulation. The results presented here should help understand the underlying mechanism of PM insults and the beneficial effect of standardized PAE as dietary supplement or cosmetical ingredient.

Screening and isolation of cyclooxygenase-2 inhibitors from the stem bark of Phellodendron amurense Ruprecht by ultrafiltration with liquid chromatography and tandem mass spectrometry, and complex chromatography. J Sep Sci 2019; 42:1905-1914. [PMID: 30843344 DOI: 10.1002/jssc.201801262] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 02/20/2019] [Accepted: 03/02/2019] [Indexed: 12/16/2022]
Abstract
Nonsteroidal anti-inflammatory drugs appear to reduce the risk of developing cancer. One mechanism through which nonsteroidal anti-inflammatory drugs act to prevent carcinogenesis is inhibition of the activity of the enzyme cyclooxygenase-2. The cyclooxygenase-2 inhibitors are widely used to reduce the risk of developing cancer. Natural products are considered to be a promising source of several novel cyclooxygenase-2 inhibitors. Ultrafiltration with liquid chromatography and mass spectrometry is an efficient method that can be applied to rapidly screen and identify the ligands from the barks of Phellodendron amurense Ruprecht. A continuous online method comprised of pressurized liquid extraction, countercurrent chromatography, and semi-preparative liquid chromatography was developed for the efficient scaled-up production of eight compounds with high purities. The bioactivities of the separated compounds were assessed by an in vitro enzyme inhibition assay. The use of bioactivity screening method combined with preparation method of bioactive compounds and an in vitro enzyme inhibition assay facilitated the efficient screening and isolation of the cyclooxygenase-2 inhibitors from complex samples. This could be used as an efficient method for the large-scale production of functional ingredients.
