Lantadenes are pentacyclic triterpenoids of the weed Lantana camara. Five new lantadenes (14-18) and their methyl esters (20-24) were synthesized, characterized, and screened for cytotoxicity against four human cancer cell lines. The parent compound (1) and the four most active compounds (15, 16,

The antitumor pentacyclic triterpenoids, Lantadene A (1) and B (2) were isolated from the leaves of weed Lantana camara L. (Verbenaceae) and were structurally transformed to bioactive intermediates 3-6. The Claisen-Schmidt reaction of 22β-hydroxy-3-oxoolean-12-en-28-oic acid (5) with requisite

BACKGROUND Eight plant species from Oaxaca, some of them used in traditional medicine, were subjected to screening of several biological activities to provide data regarding their anticancer potential, although no scientific information is available about their pharmacological

Native and exotic Brazilian plants collected in the State of Minas Gerais were evaluated for their anticancer potential. Methanol extracts from leaves of 51 plant species were tested for cytotoxicity against four tumor cell lines: B16 (murine skin), HL-60 (human leukemia), MCF-7 (human breast), and

OBJECTIVE The aim was to search for anti-inflammatory and anticancer compounds from three medicinal plants, viz. Ventilago madraspatana Gaertn., Rubia cordifolia Linn. and Lantana camara Linn. METHODS The NO* scavenging potential of selected plant extracts was determined on LPS/IFN-gamma activated

The antiproliferative activities of six medicinal plant extracts from Burkina Faso were evaluated in order to justify their traditional use for the treatment of cancer. The SOS chromotest method was used in vitro on Escherichia coli PQ37 to evaluate the mutagenic effect of the plant extracts. The

In a continuing study to isolate novel antitumor agents from rainforest plants, three new isopropenylfurano-beta-naphthoquinones, designated lantalucratins A (1), B (2), and C (3), and three new isoprenyl-alpha-naphthoquinones, designated lantalucratins D (4), E (5), and F (6), were isolated from

Five new derivatives of the pentacyclic triterpenoid lantadene A (= 22beta-angeloyloxy-3-oxoolean-12-en-28-oic acid; 1) from the leaves of Lantana camara L. were synthesized, characterized, and screened for their cytotoxicities against four human cancer cell lines. The three most-potent compounds,

Hepatocellular carcinoma is one of the leading causes of death in cancer and yet no drug has proven to be a successful candidate for its treatment in advanced stages. Ursolic acid stearoyl glucoside (UASG) is a newly discovered triterpene in Lantana camara and there lies a possibility that it

BACKGROUND Several herbs are traditionally used in the treatment of a variety of ailments particularly in the rural areas of South Africa where herbal medicine is mainly the source of health care system. Many of these herbs have not been assessed for safety or toxicity to tissue or organs of the

Verbascoside [1] isolated from Lantana camara is an inhibitor of protein kinase C (PKC) from the rat brain. Half-maximal inhibition of the kinase occurs at 25 microM. Verbascoside interacted with the catalytic domain of PKC and was a competitive inhibitor with respect to ATP (Ki = 22 microM) and a

Lantana camara, widely used in folk medicine, possesses several pharmacological properties, including antipyretic, antimicrobial and antimutagenic properties. Lantana poisoning causes livestock mortality and morbidity; and also has adverse effects on humans working in lantana-infested forests,

OBJECTIVE To investigate the toxicity of methanol extract of various parts (Root, Stem, Leaf, Flower and Fruit) of Lantana camara (L. Camara) in Artemia salina. METHODS The methanol extracts of L. camara were tested for in vivo brine shrimp lethality assay. RESULTS All the tested extract exhibited

Breast cancer is one of the most common cancers worldwide, and the second most fatal cancer in women after lung cancer. Because there are instances of cancer resistance to existing therapies, studies focused on the identification of novel therapeutic drugs are very important. In this study, we
