Oxidative effects of nickel on bone marrow and blood of rats.
This study was undertaken to examine the oxidative effects of nickel (Ni) on rat blood and bone marrow. Treatment with either 100, 250, or 500 micromol/kg Ni i.p. significantly enhanced lipidExpand
Antiplatelet activity of N-methoxycarbonyl aporphines from Rollinia mucosa.
Bioassay-directed fractionation of the stems of Rollinia mucosa led to the isolation of new N-methoxycarbonyl aporphine alkaloids, romucosine A (1), romucosine B (2), romucosine C (3), and romucosineExpand
Cytotoxic constituents of the fruits of Cananga odorata.
A new guaipyridine sesquiterpene alkaloid, cananodine (1), and two new eudesmane sesquiterpenes, cryptomeridiol 11-alpha-L-rhamnoside (2) and gamma-eudesmol 11-alpha-L-rhamnoside (3), along withExpand
Four alkaloids from Annona cherimola.
Four alkaloids, annocherine A, annocherine B, cherianoine, and romucosine H, along with one known alkaloid, artabonatine B, were isolated from the MeOH extract of the stems of Annona cherimola. TheirExpand
Association between oxidative stress and cytokine production in nickel-treated rats.
The aim of this study was to evaluate a possible relationship between lipid peroxidation, cytokine production, such as interleukin-1 (IL-1), tumor necrosis factor alpha (TNF-alpha), and transformingExpand

It has been reported that nickel (Ni) crosses the human placenta and produces teratogenesis and embryotoxicity. In the present study, the effects of nickel on human term placentas were investigated.Expand
Aromin-A, an Annonaceous acetogenin from Annona cherimola.
Chromatographic fractionation of a MeOH extract from the stems of Annona cherimola led to the isolation of a new non-adjacent, bis-THF ring acetogenin (one THF ring being at C-4 and the other atExpand
New alkaloids from Annona purpurea.
Three new alkaloids, promucosine (1), romucosine F (2), and romucosine G (3), along with 28 known compounds, were isolated from the MeOH extract of stems of Annona purpurea. The structures of 1-3Expand
New sesquiterpene hydroquinones from a Taiwanese marine sponge, Hippospongia metachromia.
In addition to metachromins A (1), B (2), and E (9), two new sesquiterpene hydroquinones, hippochromins A and B (3, 4), were isolated from the Taiwanese marine sponge Hippospongia metachromia. TheExpand
The alkaloids of Artabotrys uncinatus.
A novel type of alpha,beta-butenolide alkaloid, uncinine (1), two novel oxoaporphines, artabonatine C (2) and artabonatine D (3), a new oxazoloaporphine, artabonatine E (4), and a newExpand
