Vellozia pusilla Pohl is a species of the botanic family Velloziaceae that occurs in the subtropical regions of South America and, although it lives under conditions of high solar irradiation and low water availability, shows great longevity. The methanol extract of roots, stem and leaf sheaths of this species showed an antitumoral activity through the inhibition of the enzyme Topoisomerase I when analyzed by an in vitro bioassay employing DNA repair or recombination deficient mutants of the…

Effect of the extract of Ricinus communis L. on the osmotic fragility, labeling of red blood cells with Technetium-99m and morphology of the cells
Results suggested that the proteic extract of R. communis changed the capability of binding of the red blood cells due to the stannous ion oxidation, modifying the cells structure.
Uncaria tomentosa extract: evaluation of effects on the in vitro and in vivo labeling of blood constituents with technetium-99m
The analysis of the results of the in vivo and in vitro study indicates that there is no significant alteration on the uptake of Tc-99m by the blood constituents, but it significantly decrease the labeling of blood constituents by in vitro methods.
Structure Elucidation, Antimicrobial and Cytotoxic Activities of a Halimane Isolated from Vellozia kolbekii Alves (Velloziaceae)
In the mechanism of cytotoxic action, halimane 1 interferes in two major phases of the cell cycle: in S phase, in which DNA synthesis occurs and where it is very sensitive to damage, and G2M phase which is the phase of preparation for mitosis and mitosis itself, showing apoptosis‐inducing properties.
Efeito da fração não-oleosa doRicinus communisna biodistribuição comTecnécio-99m em camundongos
There is antitumor activity in the NOFRC, but that it alters the biodistribution of Tc-99m, a fact which may result in failures in the diagnostic imaging process using this radioisotope as a marker.


Biological and Morphological Aspects of the Velloziaceae
Recent field and laboratory observations are the basis of a review of various aspects of the biology of the Velloziaceae. Some of the pollinators of the flowers have been identified. Fruit, seed and
The effect of drugs on the labeling of blood elements with technetium-99m.
This study shows that extracts of some medicinal plants can affect the radiolabeling of red blood cells with 99mTc using an in vitro technique.
A bioactive seco-rosane diterpenoid from Vellozia candida.
Bioassay-directed fractionation of the bioactive alcoholic extracts of Vellozia candida yielded a new 6,7-seco-rosane diterpenoid, candidalactone (1), which showed moderate toxicity toward DNA
A new isopimarane diterpenoid from Vellozia pusilla pohl (velloziaceae)
Um novo diterpenoide com esqueleto isopimarano, 8(9),15-isopimarandien-7-ona-20,12-carbolactona (1), foi isolado da especie Vellozia pusilla Pohl. A elucidacao estrutural desta substância baseou-se
Mechanism-based isolation and structures of some anticancer active natural products
Interesting structural features of some representative examples of natural products active in mechanism-based bioassay and cytotoxicity assays along with structure-activity relationships of synthetic analogs of some of them are presented.
