    Design and synthesis of a new series of 3,5-disubstituted isoxazoles active against Trypanosoma cruzi and Leishmania amazonensis.[Pubmed: 28152426 ]
    Chagas disease and leishmaniasis are neglected tropical diseases (NTDs) endemic in developing countries. Although there are drugs available for their treatment, efforts on finding new efficacious therapies are continuous.
    METHODS AND RESULTS:
    The natural lignans grandisin (1) and Veraguensin (2) show activity against trypomastigote T. cruzi and their scaffold has been used as inspiration to design new derivatives with improved potency and chemical properties. We describe here the planning and microwave-irradiated synthesis of 26 isoxazole derivatives based on the structure of the lignans 1 and 2. In addition, the in vitro evaluation against culture trypomastigotes and intracellular amastigotes of T. cruzi and intracellular amastigotes of L. amazonensis and L. infantum is reported.
    CONCLUSIONS:
    Among the synthesized derivatives, compounds 17 (IC50 = 5.26 μM for T. cruzi), 29 (IC50 = 1.74 μM for T. cruzi) and 31 (IC50 = 1.13 μM for T. cruzi and IC50 = 5.08 μM for L. amazonensis) were the most active and were also evaluated against recombinant trypanothione reductase of T. cruzi in a preliminary study of their mechanism of action.

    In vitro antileishmanial and antimalarial activities of tetrahydrofuran lignans isolated from Nectandra megapotamica (Lauraceae).[Pubmed: 18688887 ]
    Seven tetrahydrofuran lignans, isolated from Nectandra megapotamica (Lauraceae), were evaluated for their in vitro antileishmanial and antimalarial activities.
    METHODS AND RESULTS:
    Among the evaluated compounds, machilin-G (1a) and Veraguensin (2a) showed the highest antileishmanial activities, displaying for both compounds an IC(50) value of 18 microg/mL and an IC(90) value of 36 microg/mL, while galgravin (1b), nectandrin-A (1c), nectandrin-B (1d), calopeptin (2b) and ganshisandrine (3) were inactive against Leishmania donovani. In the antimalarial assay against Plasmodium falciparum, it was observed that calopeptin (2b) displayed moderate activity, with IC(50) values of 3800 ng/mL (D6 clone) and 3900 ng/mL (W2 clone), while the lignans 1a-1d, 2a and 3 were inactive.
    CONCLUSIONS:
    In order to compare the effect on the parasites with toxicity to mammalian cells, the cytotoxic activity of the isolated compounds were evaluated against the Vero cells, showing that all evaluated tetrahydrofuran lignans exhibited no cytotoxicity at the maximum dose tested.

    Effects of veraguensin and galgravin on osteoclast differentiation and function.[Pubmed: 22526488]
    The dried flower buds of Magnolia sp. are widely used as herbal medicines because of their anti-inflammatory, anti-malarial and anti-platelet activities.
    METHODS AND RESULTS:
    Here, we found that Veraguensin and galgravin, lignan compounds derived from Magnolia sp., dose-dependently inhibited osteoclast formation in co-cultures of bone marrow cells and osteoblastic cells. These compounds also inhibited receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclast differentiation in RAW264.7 cells and bone marrow macrophages. In the RANKL-induced signaling pathway, Veraguensin and galgravin reduced p38 phosphorylation and suppressed the expression of c-Fos, a key transcription factor for osteoclastogenesis. Veraguensin and galgravin also inhibited osteoclastic pit formation, which was accompanied by decreased mature osteoclast viability.
    CONCLUSIONS:
    In conclusion, these results indicate that Veraguensin and galgravin can inhibit bone resorption and may offer novel compounds for the development of drugs to treat bone-destructive diseases such as osteoporosis.
