    Isobavachalcone attenuates lipopolysaccharide-induced ICAM-1 expression in brain endothelial cells through blockade of toll-like receptor 4 signaling pathways.[Pubmed: 25704611]
    Inflammation has been implicated in the pathogenesis of various cerebral diseases. Thus, control of brain inflammation is regarded as one of the important therapeutic strategies for the treatment of neurodegenerative diseases such as Alzheimer׳s disease and stroke. Isobavachalcone, a flavonoid from Psoralea corylifolia, is known to possess a wide spectrum of biological activities and is expected to be useful in preventing or treating neurodegenerative diseases. However, very little is known regarding its effects on cerebral inflammation.
    METHODS AND RESULTS:
    In this study, we examined the effect of Isobavachalcone on leukocyte adhesion and intercellular adhesion molecule-1 (ICAM-1) expression in brain endothelial cells activated with lipopolysaccharide (LPS) and explored the possible mechanisms involved. Isobavachalcone significantly down-regulated LPS-induced ICAM-1 expression and leukocyte-endothelial cell adhesion and suppressed NF-κB activity which is implicated in the expression of ICAM-1. It attenuated ICAM-1 expression as well as NF-κB transcriptional activity induced by macrophage-activating lipopeptide 2-kDa (MALP-2) or polyriboinosinic polyribocytidylic acid (poly[I:C]). Isobavachalcone also down-regulated LPS or poly[I:C]-induced expression of IFN-β, which can indirectly activate NF-κB. These data imply that Isobavachalcone can modulate both MyD88-dependent and TRIF-dependent signaling of toll-like receptor 4 (TLR4).
    CONCLUSIONS:
    Taken together, our data suggest that Isobavachalcone inhibits LPS-induced ICAM-1 expression and leukocyte adhesion to brain endothelial cell by blocking TLR4 signaling and thus, has the potential to ameliorate neuronal injury in brain diseases associated with inflammation.

    Autophagy inhibition enhances isobavachalcone-induced cell death in multiple myeloma cells.[Pubmed: 22824846 ]
    Despite recent advancements in therapeutic drugs, multiple myeloma remains an incurable disease.
    METHODS AND RESULTS:
    Therefore, a more effective treatment is urgently required. In this study, we show that Isobavachalcone (IBC), a natural chalcone compound, induces apoptosis- and autophagy-related cell death in myeloma cells. The inhibition of autophagy by knocking down beclin-1 or by using autophagy inhibitors, such as 3-methyladenine, bafilomycin A and chloroquine significantly enhanced IBC-induced cell death, as demonstrated by the increased number of Annexin V-positive cells. Moreover, we demonstrate that the collapse of the mitochondrial membrane potential contributes to chloroquine and IBC-induced cell death, which is accompanied by the activation of caspase-9, and -3, the cleavage of poly (ADP-ribose) polymerase (PARP) and the proteolytic activation of protein kinase Cδ (PKCδ). Furthermore, the inhibition of the activation of PKCδ by rottlerin, an inhibitor of PKCδ, not only suppressed the activation of PKCδ, but also the apoptosis induced by the co-treatment of chloroquine and IBC, indicating the involvement of PKCδ in chloroquine plus IBC-induced cell death. Finally, the combination of chloroquine and IBC had little effect on the viability of normal peripheral blood mononuclear cells.
    CONCLUSIONS:
    As both chloroquine and IBC have been shown to be relatively specific for cancer cells, the combination of these two agents at non-toxic or sub-toxic concentrations represents an attractive novel regimen for myeloma treatment and warrants further investigation in preclinical and clinical studies.

    Efflux pumps are involved in the defense of Gram-negative bacteria against the natural products isobavachalcone and diospyrone.[Pubmed: 20160051]
    The activities of two naturally occurring compounds, Isobavachalcone and diospyrone, against documented strains and multidrug-resistant (MDR) Gram-negative bacterial isolates were evaluated.
    METHODS AND RESULTS:
    The results indicated that the two compounds exhibited intrinsic antibacterial activity against several Gram-negative bacteria, and their activities were significantly improved in the presence of an efflux pump inhibitor (MIC values decreased to below 10 microg/ml). In addition, the activities of Isobavachalcone and diospyrone against various strains exhibiting deletions of the major efflux pump components (AcrAB, TolC) were significantly increased.
    CONCLUSIONS:
    The overall results indicate that Isobavachalcone and diospyrone could be candidates for the development of new drugs against MDR strains and that their use in combination with efflux pump inhibitors reinforces their activity.

    Abrogation of Akt signaling by Isobavachalcone contributes to its anti-proliferative effects towards human cancer cells.[Pubmed: 20167420 ]
    Akt signaling pathway has attracted much attention as a promising target for cancer therapeutics. Herein, we report that Isobavachalcone (IBC), a natural chalcone, potently abrogates Akt signaling and exerts anti-proliferative effects on several human cancer cell lines.
    METHODS AND RESULTS:
    Modeling results from the Sybyl/FlexiDock program suggest that IBC potentially binds to the ATP-binding pocket of Akt, which is confirmed by the observations that IBC inhibits Akt1 kinase in vitro. Further studies reveal that IBC significantly abates Akt phosphorylation at Ser-473 and Akt kinase activity in cells, which subsequently leads to inhibition of Akt downstream substrates and evokes significant levels of apoptosis associated with mitochondria pathway.

    Isobavachalcone and bavachinin from Psoraleae Fructus modulate Aβ42 aggregation process through different mechanisms in vitro.[Pubmed: 23907009]
    Spontaneous aggregation of Aβ is a key factor in the development of Alzheimer's disease. In searching for Aβ aggregation inhibitors from traditional Chinese herbal medicines, we identified two active compounds from Psoraleae Fructus, namely Isobavachalcone and bavachinin. We further demonstrated that the two compounds modulate Aβ42 aggregation process through different mechanisms.
    METHODS AND RESULTS:
    Isobavachalcone significantly inhibits both oligomerization and fibrillization of Aβ42, whereas bavachinin inhibits fibrillization and leads to off-pathway aggregation. Both of the compounds attenuated Aβ42-induced toxicity in a SH-SY5Y cell model.
    CONCLUSIONS:
    These findings may provide valuable information for new drug development and Alzheimer's therapy in the future.

    Isobavachalcone suppresses expression of inducible nitric oxide synthase induced by Toll-like receptor agonists.[Pubmed: 23164691]
    Toll-like receptors (TLRs) play an important role by recognizing many pathogen-associated molecular patterns and inducing innate immunity. Dysregulated activation of TLR signaling pathways induces the activation of various transcription factors such as nuclear factor-κB, leading to the induction of pro-inflammatory gene products such as inducible nitric oxide synthase (iNOS).
    METHODS AND RESULTS:
    The present study investigated the effect of Isobavachalcone (IBC), a natural chalcone component of Angelica keiskei, on inflammation by modulating iNOS expression induced by TLR agonists in murine macrophages. IBC suppressed iNOS expression induced by macrophage-activating lipopeptide 2-kDa, polyriboinosinic polyribocytidylic acid, or lipopolysaccharide.
    CONCLUSIONS:
    These results indicate the potential of IBC as a potent anti-inflammatory drug.

    Inhibitory effects of bakuchiol, bavachin, and isobavachalcone isolated from Piper longum on melanin production in B16 mouse melanoma cells.[Pubmed: 20622433 ]
    An EtOH extract of fruits of Piper longum was found to exhibit a potent inhibitory effect against alpha-melanocyte-stimulating hormone (alpha-MSH)-induced melanin production in B16 mouse melanoma cells.
    METHODS AND RESULTS:
    Bioassay-directed fractionation led to the isolation of prenylated phenolic compounds bakuchiol, bavachin, and Isobavachalcone. These compounds and the crude extract of the fruits of P. longum may have suppressive effects against pigmentation by melanin in the skin.

    Isobavachalcone, a chalcone constituent of Angelica keiskei, induces apoptosis in neuroblastoma.[Pubmed: 17917255]
    Six chalcones from Angelica keiskei KOIDZUMI (Ashitaba in Japanese) and two chalcones from Humulus lupulus L. (hop) were examined for their cytotoxicity in two human neuroblastoma cell lines (IMR-32 and NB-39) and normal cells (primary culture of rat cerebellar granule cells) by [3-(4,5)-dimethyl-2-thiazolyl]-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay.
    METHODS AND RESULTS:
    All chalcones exhibited cytotoxicity against neuroblastoma cells, and two of them (Isobavachalcone and xanthoangelol H) had no effect on normal cells even at high concentration (10(-4) M) exposure. Typical morphologic features of apoptosis, including cell shrinkage, chromatin condensation, nuclear fragmentation and formation of apoptotic bodies, were observed in Isobavachalcone-treated cells by Hoechst 33342 staining. Western blot analysis showed that Isobavachalcone significantly reduced pro-caspase-3 and pro-caspase-9, and subsequently increased the level of cleaved caspase-3 and cleaved caspase-9 in both neuroblastoma cell lines. Moreover, Bax was markedly induced by Isobavachalcone application.
    CONCLUSIONS:
    These results suggest that Isobavachalcone induces apoptotic cell death in neuroblastoma via the mitochondrial pathway and has no cytotoxicity against normal cells. Therefore, Isobavachalcone may be applicable as an efficacious and safe drug for the treatment of neuroblastoma.
