  • Analysis of compound–compound interactions between berberine and baicalin derivatives

    Takehiro Nishimura, Chihiro Iida, Haruhisa Kikuchi

    Journal of Natural Medicines (Springer Science and Business Media LLC)   2025.11

    Last author, Corresponding author, Accepted,  ISSN  1340-3443

    　View Summary

    In multicomponent drugs, such as Kampo (traditional Japanese medicine) medicines, compound–compound interactions, including synergistic effects, inhibitory effects, and complex formations, should be considered. Orengedokuto is a Kampo formula, which is used for the treatment of various diseases, including inflammation, hypertension, gastrointestinal disorders, and liver and cerebrovascular diseases. During the decoction process in the production of Orengedokuto, yellow precipitates are obtained from berberine–baicalin complexation; these precipitates enhance the in vivo coprecipitation and coabsorption of both compounds. Scutellaria root contains various baicalin analogs, such as wogonoside, oroxyloside, and scutellarin; however, the compound–compound interactions between berberine and flavonoid glycosides have not been investigated. Herein, we performed precipitation assays for berberine and the crude extract of Scutellaria root to detect and quantify compounds that interact with berberine by HPLC analysis. Furthermore, we performed precipitation assays and NMR experiments to identify chemical structures that affect the formation of precipitates; specifically, we analyzed all combinations of berberine and identified flavonoids to provide insights into associated compound–compound interactions. The NMR experiments indicated that C-8 modification affected the pi–pi interaction between berberine and flavonoids. This information enables the synthesis of more effective molecules and provides insights into their functions, such as drug delivery. The investigation of the interaction mechanisms of berberine and baicalin analogs in Kampo medicines can provide comprehensive insights regarding multicomponent drugs.

  • Inhibition kinetics of citrus jabara juice and its components on CYP2C9 activity

    Kana Koinuma, Tokio Morita, Yoshinori Uekusa, Haruhisa Kikuchi, Ayuko Imaoka, Takeshi Akiyoshi, Hisakazu Ohtani

    　View Summary

    Our previous studies demonstrated that the ethyl acetate extract of the juice of jabara (JEx), a Japanese citrus fruit, inhibited cytochrome P450 (CYP) 3A4 activity in a time-dependent manner, but does not inhibit CYP2C19 activity. Its components, 3,3′,4′,5,6,7,8-heptamethoxyflavone (HpMF) and 3,3′,4′,5,6,7-hexamethoxyflavone (HxMF), have been shown to be responsible for this CYP3A4 inhibition. This study aimed to investigate the nature of CYP2C9 inhibition by JEx, HpMF, and HxMF. The time-dependent inhibition kinetics of JEx against human recombinant CYP2C9 were investigated in vitro using warfarin as a substrate. The time-independent inhibition kinetics of JEx, HpMF, and HxMF against CYP2C9 were also determined. JEx did not cause time-dependent inhibition of CYP2C9, while JEx, HpMF, and HxMF inhibited CYP2C9 activity in a time-independent manner with IC<inf>50</inf> values of 2.65 % equivalent, 16.2 µM, and 57.8 µM, respectively. HpMF and HxMF were considered to be primarily responsible for CYP2C9 inhibition by JEx. The ingestion of 250 mL of jabara juice was estimated to reduce intestinal CYP2C9 activity to 3 % of the control value assuming of dilution with 210 mL of intestinal fluid, suggesting that jabara juice may cause food-drug interactions via intestinal CYP2C9 inhibition.

    　View Summary

    Objective: Dictyostelium differentiation-inducing factors 1 and 3 [DIF-1 (1) and DIF-3 (2), respectively], along with their derivatives, such as Ph-DIF-1 (3) and Bu-DIF-3 (4), demonstrate antibacterial activity in vitro against Gram-positive bacteria, including methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), vancomycin-sensitive Enterococcus faecalis (VSE), and vancomycin-resistant Enterococcus faecium [VRE (VanA)]. This study investigates the therapeutic potential of DIF compounds against these Gram-positive bacteria. Results: In vitro tests revealed that the antibacterial activity of 3 and 4 was lost in the presence of human serum albumin (HSA), suggesting that HSA might inhibit their effectiveness. Further evaluation of less hydrophobic derivatives, DIF-1-NH<inf>2</inf> (5) and NH<inf>2</inf>-Bu-DIF-3 (6), showed no antibacterial activity, even in the absence of HSA. However, ester derivatives Ph-DIF-1(AHA) (7) and Bu-DIF-3(2Ac) (8) exhibited antibacterial activity against the target bacteria in vitro, although this activity was also lost in the presence of HSA. We hypothesize that these ester derivatives may function as prodrugs, with their antibacterial activity possibly restored by hydrolysis through bacterial esterases. The results suggest that suitable ester modifications could enhance the in vivo antibacterial potential of DIF compounds, particularly if they can bypass HSA binding and be activated by bacterial enzymes.

  • Kinetics of the Inhibition of CYP3A4 and CYP2C19 Activity by Jabara Juice and Identification of the Responsible Inhibitory Components

    　View Summary

    Some citrus fruits are known to cause clinically significant drug interactions by inhibiting intestinal cytochrome P450 (CYP) enzymes. This in vitro study aimed to investigate the kinetics of the inhibition of CYP3A4 and CYP2C19 by the juice of jabara, a Japanese citrus fruit that does not contain furanocoumarins such as 6′,7′-dihydroxybergamottin, and to identify the inhibitory compound(s). CYP3A4 and CYP2C19 activity levels were determined in vitro using recombinant CYP preparations and their respective substrates. The ethyl acetate extract (EAE) of jabara juice was separated to isolate and identify the compound(s) that inhibited CYP3A4. Then, the time-dependent kinetics of the inhibition of CYP3A4 and CYP2C19 by the EAE and its inhibitory compound(s) were analyzed. The EAE of jabara juice was found to inhibit CYP3A4 in a time-dependent manner. Two flavonoids, 3,3′,4′,5,6,7,8-heptamethoxyflavone (HpMF) and 3,3′,4′,5,6,7-hexamethoxyflavone (HxMF), were identified as the responsible compounds. HpMF and HxMF inhibited CYP3A4 activity in a concentration- and time-dependent manner, with inhibition constants (KI) of 10.0 and 7.90 µM and maximal inactivation rate constants (kinact,max) of 0.00856 and 0.0134 min−1, respectively. The EAE did not inhibit CYP2C19, even when preincubation was employed. These findings imply that jabara juice may cause food-drug interactions via time-dependent inhibition of intestinal CYP3A4.

  • A longer-chain acylated derivative of Dictyostelium differentiation-inducing factor-1 enhances the antimalarial activity against Plasmodium parasites

    　View Summary

    The spread of malarial parasites resistant to first-line treatments such as artemisinin combination therapies is a global health concern. Differentiation-inducing factor 1 (DIF-1) is a chlorinated alkylphenone (1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl) hexan-1-one) originally found in the cellular slime mould Dictyostelium discoideum. We previously showed that some derivatives of DIF-1, particularly DIF-1(+2) (1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl) octan-1-one), exert potent antimalarial activities. In this study, we synthesised DIF-1(+3) (1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl) nonan-1-one). We then evaluated the effects of DIF-1(+3) in vitro on Plasmodium falciparum and in vivo over 7 days (50–100 mg/kg/day) in a mouse model of Plasmodium berghei. DIF-1(+3) exhibited a half-maximal inhibitory concentration of approximately 20–30 % of DIF-1(+2) in three laboratory strains with a selectivity index > 263, including in strains resistant to chloroquine and artemisinin. Parasite growth and multiplication were almost completely suppressed by treatment with 100 mg/kg DIF-1(+3). The survival time of infected mice was significantly increased (P = 0.006) with no apparent adverse effects. In summary, addition of an acyl group to DIF-1(+2) to prepare DIF-1(+3) substantially enhanced antimalarial activity, even in drug-resistant malaria, indicating the potential of applying DIF-1(+3) for malaria treatment.

    　View Summary

    As described in Japanese essay (Hojoki), written around 1200, various disasters such as big fires, earthquakes, and famines have occurred in Japan. Asian countries have been suffering from the disasters; furthermore, natural disasters are increasing due to global warming. Because tropical-infectious diseases are often disaster-related infectious diseases (DRIDs), the strategies against the former kind of disease could be applicable to DRIDs. Meteorological analysis of the occurrence of DRIDs using a method of time series analysis is important. In situations of disasters, it is desirable if you can identify the pathogen and identify disease severity simultaneously. A dipstick DNA chromatography assay termed as Single-Tag Hybridization—Printed Array Strip (STH—PAS) system was developed based on the DNA sequences of various mosquito-borne diseases. The plasma levels of matricellular proteins including galectin-9 (Gal-9) and osteopontin (OPN) were found to reflect the disease severities in the dengue virus and other DIRDs. Because both proteins have been reported to be immune-check molecules, their inhibition might enhance the immune system against pathogens. We found that brefelamide derivatives could inhibit OPN and other inflammatory molecules synthesis. Very recently, different derivatives were found to inhibit PD-L1 transcription. Applications of these agents should be considered as multi-step strategies against DRIDs.

    　View Summary

    Cellular slime molds are thought to be excellent model organisms for the study of cell and developmental biology because of their simple pattern of development. However, there have been few reports on secondary metabolites of them. We have focused on the utility of cellular slime molds as novel resources for natural product chemistry, and have studied the diversity of secondary metabolites produced by them as well as their physiological and pharmacological activities. We have recently isolated many novel compounds from the fruiting bodies of various species of Dictyostelium cellular slime molds. Total syntheses and biological evaluation of these compounds have been carried out. It was shown that dictyopyrones and dictyomedins may regulate Dictyostelium development. Amino sugar derivatives such as furanodictines and dictyoglucosamines induced neuronal differentiation of rat PC-12 cells. In addition, brefelarnide inhibited the cellular proliferation of 1321N1 human astrocytorna cells. These results show that cellular slime molds are promising sources in natural product chemistry.
