The effects of five antifungal drugs, fluconazole, itraconazole, micafungin, miconazole, and voriconazole, on cytochrome P450 (CYP) 2C9-mediated tolbutamide hydroxylation, CYP2C19-mediated S-mephenytoin 4′-hydroxylation, and CYP3A4-mediated nifedipine oxidation activities in human liver microsomes were compared. In addition, the effects of preincubation were estimated to investigate the mechanism-based inhibition. The IC50 value against tolbutamide hydroxylation was the lowest for miconazole (2.0 μM), followed by voriconazole (8.4 μM) and fluconazole (30.3 μM). Similarly, the IC50 value against S-mephenytoin 4′-hydroxylation was the lowest for miconazole (0.33 μM), followed by voriconazole (8.7 μM) and fluconazole (12.3 μM). On the other hand, micafungin at a concentration of 10 or 25 μM neither inhibited nor stimulated tolbutamide hydroxylation and S-mephenytoin 4′-hydroxylation, and the IC50 values for itraconazole against these were greater than 10 μM. These results suggest that miconazole is the strongest inhibitor of CYP2C9 and CYP2C19, followed by voriconazole and fluconazole, whereas micafungin would not cause clinically significant interactions with other drugs that are metabolized by CYP2C9 or CYP2C19 via the inhibition of metabolism. The IC50 value of voriconazole against nifedipine oxidation was comparable with that of fluconazole and micafungin and higher than that of itraconazole and miconazole. The stimulation of the inhibition of CYP2C9-, CYP2C19-, or CYP3A4-mediated reactions by 15-min preincubation was not observed for any of the antifungal drugs, suggesting that these drugs are not mechanism-based inhibitors.

This study was conducted to investigate the chemical component of the hot water (HW) fraction of mycelia of Cordyceps sinensis and its antifatigue and antistress effect against a stimulus in vivo using rats and mice. The growth of mycelia reached a maximum level of 31.6 g/l after 120 h of incubation. The main chemical composition of the HW fraction of mycelia of C. sinensis was found to be carbohydrate (78.9%) with 5% moisture. The swimming endurance capacity of mice orally administered with the HW fraction (150 and 300 mg/kg/d, respectively) was significantly prolonged from 75 to 90 min with a lessening of fatigue. When the HW fraction (150 mg/kg/d) was given to rats for 8 d including a 48 h stress period, the weight changes of the adrenal gland, spleen, thymus, and thyroid, which is an index of stress, were suppressed. The HW fraction also significantly inhibited the increase in total cholesterol and the decrease in alkaline phosphatase levels as biochemical parameters of immobilization stress in rats.

A 1H-NMR method has been developed for the quantitative analysis of pure cannabinoids and for cannabinoids present in Cannabis sativa plant material without any chromatographic purification. The experiment was performed by the analysis of singlets in the range of δ 4.0—7.0 in the 1H-NMR spectrum, in which distinguishable signals of each cannabinoid are shown. Quantitation was performed by calculating the relative ratio of the peak area of selected proton signals of the target compounds to the known amount of the internal standard, anthracene. For this method no reference compounds are needed. It allows rapid and simple quantitation of cannabinoids with a final analysis time of only 5 min without the need for a pre-purification step.

Danggui Buxue Tang (DBT), a combination of Astragalus and Angelica at a 5 : 1 ratio, mainly promotes hematopoiesis. However, in the clinic, the combination ratio of Astragalus and Angelica to treat low hematopoietic function is not an absolute 5 : 1 ratio, suggesting that the herbs may promote hematopoiesis better after being combined at a certain range of ratios. The objective of this study is to investigate the effect of different ratio combinations of Astragalus and Angelica on bone marrow hematopoiesis suppression induced by cyclophosphamide (CTX) and to probe the interaction and mechanism of Astragalus combined with Angelica in promoting hematopoiesis. Following establishment of the model, mice were administered with Astragalus (6.00 g·kg−1), Angelica (3.00 g·kg−1), and combinations of Astragalus and Angelica at different ratios, including 10 : 1 (Astragalus 9.81 g·kg−1+Angelica 0.98 g·kg−1), 5 : 1 (Astragalus 9.00 g·kg−1+Angelica 1.80 g·kg−1), 2 : 1 (Astragalus 7.71 g·kg−1+Angelica 3.08 g·kg−1), 1 : 1 (Astragalus 5.40 g·kg−1+Angelica 5.40 g·kg−1), 1 : 2.5 (Astragalus 3.08 g·kg−1+Angelica 7.71 g·kg−1), 1 : 5 (Astragalus 1.80 g·kg−1+Angelica 9.00 g·kg−1), and 1 : 10 (Astragalus 0.98 g·kg−1+Angelica 9.81 g·kg−1). Our results suggested that Astragalus mixed with Angelica synergistically promoted hematopoiesis best when the combination ratio of Astragalus and Angelica was 1 : 1, 1 : 2.5 or 1 : 5; moreover, the effect of Angelica was greater than that of Astragalus. The potential mechanisms of the combinations of Astragalus and Angelica that promote hematopoiesis include the dissolution of the effective components, promoting the synthesis and secretion of hematopoietic growth factor (HGF) and the proliferation of hematopoietic progenitor cells (HPCs).

We observed that uncoated furosemide tablets turned yellow in a light-shielded automatic packaging machine and discoloration of the furosemide tablets was heterogeneity and occurred on the surface of the tablets only. The machine was equipped with an internal blower to maintain a constant temperature. Therefore, we investigated the effect of air flow on the discoloration of the furosemide tablets using a blower in a dark environment. The color difference (ΔE) of the furosemide tablets increased linearly as the blowing time increased. We performed structural analysis of the yellow compound in the furosemide tablets by LC-MS and identified the compound as a hydrolysate of furosemide. This suggested that furosemide hydrolysis was accelerated by the air flow. The furosemide tablets were prepared with the most stable furosemide polymorph, form I. X-Ray powder diffractometry and IR spectroscopy showed that during tablet preparation, no crystal transition occurred to an unstable furosemide polymorph. Furthermore, IR spectroscopy showed that the crystal form of furosemide in the yellow portion of the tablets was form I. To elucidate the factors producing the discoloration, we investigated the effect of humidity and atmosphere (air, oxygen, and nitrogen) on the discoloration of the furosemide tablets. The results suggested that the discoloration of the furosemide tablets was accelerated by oxidation, although humidity did not affect the hydrolysis. Therefore, we concluded that the discoloration of the furosemide tablets in the automatic packing machine was caused by acceleration of oxidative degradation by air flow.

One century has passed since fugu toxin was named tetrodotoxin (TTX) by Tahara. Chemical problems such as crystallization of tetrodotoxin and subsequent structure determination were solved by research groups headed by Tsuda, Hirata, Woodward, and Mosher. The International Symposium on the Chemistry of Natural Products in Kyoto (1964) was well known as symposium which the structure of TTX was internationally clarified. Since the first isolation of toxin from taricha torosa (imori) as natural source except for fugu fishes, distribution of toxin in nature has been widely investigated. And, it was proved that toxin is not produced by fugu fishes, but rather is formed by sea bacteria (30 sp.) such as Alteromonas sp, Vibrio sp, Shewanella. However, it seems to be difficult to explain the tetrodotoxin accumulation at high concentration in fugu by only toxin production by bacteria. TTX analogues were isolated from natural origins such as crabs, fish, annelids, and algae. Based on the structure of these toxin analogues, the biosynthesis of toxin and the structure-activity relationship (Na^+ channel) were proposed by Yasumoto-Yamashita. The findings of wide distribution of toxin in nature may be attributed to development of highly sensitive detection method for toxin. The interesting proposal for the biosynthesis and the structure activity, and the detection method for toxin are outlined in this review.

Extract of the whole plant, Ajuga decumbens (KE) has long been used in China as a medication for the relief of joint pain. Previously, we proved that KE up-regulated the synthesis of collagen in false aged model rats. In this paper we examined the effects of KE on nitric oxide (NO) production, expression of inducible nitric oxide synthase (iNOS), osteoblast and osteoclast activity. We also investigated whether KE had any anti-osteoporosis or anti-arthritic activity by using ovariectmized mice and adjuvant induced arthritic rats. KE exhibited down-regulation of differentiation into osteoclast and up-regulation of mineralization in osteoblast-like MC3T3-E1 cells in a concentration-dependent manner. NO synthesized by iNOS plays important roles in inflammatory disease and imbalance between bone resorption and bone formation caused by estrogen depletion. KE inhibited expression of iNOS which caused concentration dependent inhibition of NO production. Furthermore, KE prevented brittle bones in ovariectomized mice and swelling of the left hind ankle in adjuvant induced arthritic rats. Therefore, KE improved the balance of bone resorption and bone formation, showing anti-inflammatory effects. Consequently, KE is beneficial for sufferers of bone and joint disease.

Cisplatin (CDDP) combination chemotherapy is widely administered to patients with advanced lung cancer. The dose depends on multiple factors, including whether the tumor is non-small-cell lung cancer (NSCLC) or small-cell lung cancer (SCLC). Although efficacy is limited by cisplatin-induced nephrotoxicity (CIN), little is known about the risk factors for this complication. The aim of this study was to identify the risk factors for CIN in patients with advanced lung cancer, both NSCLC and SCLC. We retrospectively reviewed clinical data for 148 patients who underwent initial chemotherapy including CDDP ≥50 mg/m2 per patient per day for the first course at Kyushu Medical Center between October 2010 and September 2013. All data were collected from the electronic medical record system. Nephrotoxicity was defined as an increase in serum creatinine concentration of at least grade 2 during the first course of CDDP chemotherapy, as described by the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. CIN was observed in nine patients. Univariate analysis revealed that cardiac disease and lower baseline serum albumin (Alb) values conferred a higher risk of nephrotoxicity (p<0.05). The cut-off value of Alb was 3.8 g/dL, calculated by receiver operating characteristics (ROC) curves. Multivariable logistic regression analysis revealed that cardiac disease (odds ratio=11.7; p=0.002) and hypoalbuminemia (odds ratio=6.99 p=0.025 significantly correlated with nephrotoxicity. In conclusion, cardiac disease and low baseline Alb values are possible risk factors for CIN.

Berberine is one of the main active constituents of Rhizoma coptidis, a traditional Chinese medicine, and has long been used for the treatment of gastrointestinal disorders. The present study was designed to investigate the effects of berberine on the intestinal mucosal barrier damage in a rat uremia model induced by the 5/6 kidney resection. Beginning at postoperative week 4, the uremia rats were treated with daily 150 mg/kg berberine by oral gavage for 6 weeks. To assess the intestinal mucosal barrier changes, blood samples were collected for measuring the serum D-lactate level, and terminal ileum tissue samples were used for analyses of intestinal permeability, myeloperoxidase activity, histopathology, malondialdehyde (MDA) level, and superoxide dismutase (SOD) activity. Berberine treatment resulted in significant decreases in the serum D-lactate level, intestinal permeability, intestinal myeloperoxidase activity, and intestinal mucosal and submucosal edema and inflammation, and the Chiu’s scores assessed for intestinal mucosal injury. The intestinal MDA level was reduced and the intestinal SOD activity was increased following berberine treatment. In conclusion, berberine reduces intestinal mucosal barrier damage induced by uremia, which is most likely due to its anti-oxidative activity. It may be developed as a potential treatment for preserving intestinal mucosal barrier function in patients with uremia.

It is unknown whether nutritional status influences pain intensity in cancer patients receiving a transdermal fentanyl patch (FP). This study aimed to determine whether nutritional status is associated with pain intensity and to evaluate the influence of changes in nutritional status on pain intensity in cancer patients receiving transdermal FP treatment. We included 92 patients receiving transdermal FP treatment for the first time with switching from oxycodone. The patients were classified into low- and normal-nutrition groups based on their nutritional status, which was assessed according to the Nutrition Risk Screening 2002 (NRS 2002) parameters. The pain intensity of each patient was evaluated by a numeric rating scale (11-point scale from 0 to 10). NRS 2002 score and pain intensity were obtained on day 3 after the FP was applied to the skin. Pain intensities were significantly higher among patients in the low-nutrition group than among patients in the normal-nutrition group. NRS 2002 scores showed a significant positive correlation with the pain intensities. In 52 of 92 patients, who were evaluated using the NRS 2002 score and pain intensity on day 30 after FP application, the changes in NRS 2002 scores were significantly related to changes in pain intensities (odds ratio, 30.0; 95% confidence interval, 4.48–200.97; p=0.0005). These results suggest that an increase in the NRS 2002 score is a risk factor for an increase in pain intensity in cancer patients receiving FP treatment. Malnutrition may lead to poor pain management in cancer patients receiving FP treatment.
