annona hayesii/breast neoplasms

Annona reticulata Linn. (Common name: Bullock's-heart) (Annonaceae family) is a semi-evergreen and small deciduous tree. The extracts of various parts of Annona reticulata L. have been reported as cytotoxic to many cancer cells. Annona reticulata L. leaves' methanolic extract (ARME) was prepared and

The epidermal growth factor receptor (EGFR) is an oncogene frequently overexpressed in breast cancer (BC), and its overexpression has been associated with poor prognosis and drug resistance. EGFR is therefore a rational target for BC therapy development. This study demonstrated that a graviola fruit

Background: Triple negative breast cancers (TNBCs) are having high morbidity and shorter survival rate in the population. These types of cancers are having high aggressiveness, lymphatic invasion and absence of receptors. The treatment

Breast cancer is a global public health problem where it is the second most prevalent cancer. Historical cancer treatment with graviola has been reported. This study aimed to investigate the protective effects of graviola on 7,12-dimethylbenz[a]anthracene (DMBA)-induced rat breast cancer. Fifty

Annona muricata L., known as graviola, is an evergreen plant of the tropical regions and is a rich source of natural products. Graviola has various biological activities, and it is best known for its anticancer activity. This study aimed to investigate the effects of crude graviola extract in vitro

BACKGROUND Annona muricata Linn which comes from Annonaceae family possesses many therapeutic benefits as reported in previous studies and to no surprise, it has been used in many cultures to treat various ailments including headaches, insomnia, and rheumatism to even treating cancer. However,

In this study we screened the cytotoxicity of 1220 plant extracts obtained from 351 plants belonging to 74 families occurring in the Amazon and Atlantic rain forests against MCF-7 human breast adenocarcinoma cell lines. All extracts were tested at a dose of 100 microg/mL. Only 11 aqueous or organic

Objective: In the study our aim was to evaluate the cytotoxic activity of different solvent extracts of Annonasquamosa seeds. Methods and materials: The four extracts used were petroleum ether, chloroform, ethyl acetateand methanol were tested using cytotoxicity assays. Results: Among the four

Activity-guided fractionation of the stem bark of Annona senegalensis gave four bioactive ent-kaurenoids (1-4). Compound 2 showed selective and significant cytotoxicity for MCF-7 (breast cancer) cells (ED50 1.0 microgram/mL), and 3 and 4 exhibited cytotoxic selectivity for PC-3 (prostate cancer)

Eight new mono-tetrahydrofuran (THF)-type annonaceous acetogenins, squafosacins B, C, F, and G (1-4), squadiolins A-C (5-7), and cis-annotemoyin-1 (8), as well as eight known annonaceous acetogenins, glabranin, annotemoyins-1 and -2, bullatencin, cis-bullatencin, and uvariamicins-I, -II, and -III,

Several endophytic fungal strains from Srikaya plants (Annona squamosa L.) have been isolated and one of them was identified as Penicillium sp. Penicillium has been proven as an established source for a wide array of unique bioactive secondary metabolites that exhibit a variety of biological

Plants became the basis of traditional medicine system throughout the world for thousands of years and continue to provide mankind with new remedies. Annona muricata, the plant of Annonaceae family, is also known as sour sop or Graviola. In recent years, many compounds have been reported and have

In our continuing activity-directed search for new antitumor compounds, using brine shrimp lethality (BST), mixtures of three additional pairs (1-6) of bis-THF ketolactone acetogenins were isolated from the ethanol extract of the bark of Annona bullata Rich. (Annonaceae). Compared with (2,4-cis and

BACKGROUND Tamoxifen resistance is common in estrogen receptor-α (ERα)-positive breast cancers. Pawpaw and soursop are anticancer annonaceous plants in complementary medicine. Thus, we studied the effects of annonacin, an annonaceous acetogenin, in breast cancer cells. METHODS Cell growth and
