hyptis atrorubens/neoplasms

Background and objective: Hyptis suaveolens is an aromatic plant used in traditional medicine in Burkina Faso for management of various diseases including wounds and inflammatory diseases. Thus, the objective of this work was to

Hyptis pectinata is a herb popularly used in Brazil for the treatment of inflammations, pain, bacterial infections and cancer. In the present study, inflorescences (MPIn), leaves (MPL), branches (MPB), root (MPR) extracts and three compounds isolated from MPIn were assayed against breast

UNASSIGNED Research the antitumor effects of ethanol extracts from Hyptis rhomboidea in H22 tumor-bearing mice. At the fist-stage of the experiments, the research team took MTT method to measure the antitumor activity in vitro, then selected the most inhibitory tumor cell strain as the test object

There are estimated to be more than 20,000 species of plants in Venezuela, of which more than 1500 are used for medicinal purposes by indigenous and local communities. Only a relatively small proportion of these have been evaluated in terms of their potential as antitumor agents. In this study, we

OBJECTIVE Hyptis pectinata Poit (Lamiaceae) is grown in the northeastern regions of Brazil and is popularly known as "sambacaitá" or "canudinho". It is extensively used in folk medicine to treat inflammatory conditions, bacterial infections, pain, and cancer. METHODS Hyptis pectinata essential oil

Hyptis pectinata, popularly known in Brazil as "sambacaitá" or "canudinho," is an aromatic shrub largely grown in the northeast of Brazil. The leaves and bark are used in an infusion for the treatment of throat and skin inflammations, bacterial infections, pain, and cancer. Analogues of rosmarinic

The hedgehog (Hh) signaling pathway plays crucial roles in cell maintenance and proliferation during embryonic development. Naturally occurring Hh inhibitors were isolated from Artocarpus communis and Hyptis suaveolens using our previously constructed cell-based assay system. Bioactivity guided

As most anticancer drugs are derived from natural sources, the screening of local medicinal flora should be considered a primary step in the search for new sources for antineoplastic agents. In Mexico, more than 6000 medicinal plant species are used for the treatment of various diseases, including

The compounds terrein (1), butyrolactone I (2), and butyrolactone V (3) were isolated from the ethyl acetate extract (EtOAc) of the endophytic fungus Aspergillus terreus-F7 obtained from Hyptis suaveolens (L.) Poit. The extract and the compounds presented schistosomicidal activity against

Brevipolides K-O (1-5), five new cytotoxic 6-(6'-cinnamoyloxy-2',5'-epoxy-1'-hydroxyheptyl)-5,6-dihydro-2H-pyran-2-ones (IC50 values against six cancer cell lines, 1.7-10 μM), were purified by recycling HPLC from Hyptis brevipes. The structures, containing a distinctive tetrahydrofuran ring, were

The (6'S)-configuration of brevipolides A-J (1-10), isolated from Hyptis brevipes, was established by X-ray diffraction analysis of 9 in conjunction with Mosher's ester analysis of the tetrahydro derivative 11 obtained from both geometric isomers 8 and 9 as well as by chemical correlations. The

By bioactivity-directed fractionation, three new antimicrobial and cytotoxic 5,6-dihydro-alpha-pyrones, pectinolides A-C, have been isolated from Hyptis pectinata (Lamiaceae). The absolute stereochemistry of pectinolide A [1] was established as 6S-[(3S-acetyloxy)-1Z-heptenyl]-5S-(acetyloxy)-5

BACKGROUND Adult T-cell leukemia is an aggressive hematological malignancy with a poor clinical prognosis, and a rapid resistance to chemotherapy is rapid. METHODS Cytotoxicity assay-directed fractionation identified a novel lignan-related agent, 4-methoxy-9-(3,4,5-trimethoxyphenyl)-8, 9 -

A new cytotoxic (P-388 ED50 4 microgm/ml) arylnaphthalene lignan has been isolated from the Mexican medicinal plant Hyptis verticillata (Lamiaceae) and characterized as 5-methoxydehydropodophyllotoxin [1]. Eight additional lignans were also obtained by bioactivity-directed fractionation using the
