“…The presence of a wide array of secondary metabolites from Machaerium, including flavonoids, terpenoids and oxygenated phenolic compounds, together with their bioactivities, has recently been reviewed by Amen et al [2]. Anticancer and antioxidative activities were reported from M. cuspidatum [5], and a cytotoxic cinnamylphenol was isolated from M. aristulatum [6].…”

Machaeriols and machaeridiols are unique hexahydrodibenzopyran-type aralkyl phytocannabinoids isolated from Machaerium Pers. Earlier studies of machaeriol A (1) and B (2) did not show any affinity for cannabinoid receptor 1 (CB1 or CNR1), although they are structural analogs of psychoactive hexahydrocannabinol. This study comprehensively reports on the affinities of isolated Machaerium Pers. compounds, namely machaeriol A–D (1–4) and machaeridiol A–C (5–7), against cannabinoid (CB1 and CB2) and opioid (κ, δ and µ) receptors. Among the isolated compounds, machaeriol D (4) and machaeridiol A–C (5–7) showed some selective binding affinity for the CB2 receptor, using a radioligand binding assay, with Ki values of >1.3, >1.77, >2.18 and >1.1 μM, respectively. On the other hand, none of the compounds showed any binding to the CB1 receptor. Due to recent reports on the anticancer potential of the endocannabinoid system, compounds 1–7 were tested against a battery of luciferase reporter gene vectors that assess the activity of many cancer-related signaling pathways, including Stat3, Smad2/3, AP-1, NF-κB, E2F, Myc, Ets, Notch, FoxO, Wnt, Hedgehog and pTK in HeLa and T98G glioblastoma cells. Complete dose–response curves have been determined for each compound in both of these cell lines, which revealed that machaeridiol 6 displayed activities (IC50 in µM in HeLa and T98G cells) towards Stat3 (4.7, 1.4), Smad2/3 (1.2, 3.0), AP-1 (5.9, 4.2), NF-κB (0.5, 4.0), E2F (5.7, 0.7), Myc (5.3, 2.0), ETS (inactive, 5.9), Notch (5.3, 4.6), Wnt (4.2, inactive) and Hedgehog (inactive, 5.0). Furthermore, a combination study between machaeriol C (3) and machaeridiol B (6) displayed additive effects for E2F, ETS, Wnt and Hedgehog pathways, where these compounds individually were either minimally active or inactive. None of the compounds inhibited luciferase expression driven by the minimal thymidine kinase promoter (pTK), indicating the lack of general cytotoxicity for luciferase enzyme inhibition at the 50 µM concentration in both of these cell lines. The significance of the inhibition of these signaling pathways via machaeridiol 5–7 and their cross-talk potential has been discussed.

This study was to demonstrate the comparison of immunological activity between vegetable soup made by fresh and extruded radish in in-vitro (bone marrow-derived macrophages and dendritic cells, and mouse splenocytes) and invivo models. In cell survival tests, extruded radish added to vegetable soup (EVS) and non-extruded radish added to vegetable soup powder (NEVS) were treated with bone-marrow derived macrophages, dendritic cells, and mouse splenocytes, and showed no cytotoxic effect at a dose below 1000 μg/mL. EVS treated cells had greater cell proliferation and cytokine [tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, IL-2, interferon (INF)-γ] production when compared to the NEVS treated group. Cell surface marker (CD 80/86, MHC class I/II) expression in bone marrow-derived macrophages and dendritic cells was evenly increased in the EVS treated group. In in-vivo study, administration of EVS increased for the CD4 and CD8 T cell population in splenocyte and cytokine production (IL-2, IFN-γ, TNF-α) but not Th2 type cytokines (IL-4). Therefore, adding the extruded radish is a more effective method for vegetable soup to increase immunological activity against immune cells.
