Cytotoxic Activity of Tunicate Hemocytes
1996Tunicates (protochordates) are filter-feeding marine invertebrates with a worldwide distribution. In their larval form, they exhibit many of the features characteristic of the vertebrates. The larva, with a tail, notochord, and dorsal neural tube, upon settlement undergoes a remarkable metamorphosis in which it loses most of its chordate ...

Cytotoxic Activity of Lymphocytes
The Journal of Immunology, 1975Abstract Macrophage cell-mediated cytolysis (M-CMC) of tumor cells may be measured by culturing target cells on macrophage monolayers and determining target cells on macrophage monolayers and determining target cell survival by either 86Rb or 3H-thymidine incorporation.

Cytotoxic Activity of Lymphocytes
The Journal of Immunology, 1976Abstract Two different lymphotoxins synthesized by human blood lymphocytes stimulated with phytohemagglutin (PHA) are described. The two toxins are called α-LT and β-LT relative to their elution order on gel chromatography. Their m.w. are 75,000 and 45,000 daltons, respectively.

Regulation of Natural Cytotoxic Activity
1982DISCUSSION INTRODUCER GUSTAVO CUDKOWICZ: If naturally occurring cytotoxic cells are to fulfill an important biological function, they will be integrated and they will be regulated. Only in the last few years have studies been conducted on NK cell regulation.

Cytotoxic Activity of Styryl Lactones and their Derivatives
Current Medicinal Chemistry-Anti-Cancer Agents, 2001Many studies that have been conducted to establish the cytotoxic potency of styryl lactones for several tumor cell lines is described. Extensive examination of the activity of more than 50 cytotoxic styryl lactones isolated/synthesized belonging to the genus goniothalamus representing future generation of antitumor drugs is described for the first time

Cytotoxic activity of amooranin and its derivatives
Phytotherapy Research, 2002Amooranin, 25-hydroxy-3-oxoolean-12-en-28-oic acid, is a triterpene acid isolated from Amoora rohituka stem bark. The cytotoxic effects of amooranin and its derivatives were studied. Amooranin and its methyl ester showed greater cytotoxicity against MCF-7 and HeLa cells derived from tumour tissues with a 50% inhibitory concentration (IC(50)) of 1.8-3.4

Antiproliferative and Cytotoxic Activities
2018Cancer is a genetic disease, affecting many people worldwide. Chemotherapy is routinely used for cancer treatment. However, this therapeutic approach is not always effective due to the development of cell resistance and toxic effects. Plants are a reservoir of natural chemicals with chemoprotective potential against cancer and with low adverse effects.

Cytotoxic Activity and Apoptosis Induction by Gaillardin
Zeitschrift für Naturforschung C, 2013Cytotoxic activity of gaillardin, a sesquiterpene lactone isolated from Inula oculus-christi L. (Asteraceae), was assessed in the human breast adenocarcinoma cell line MCF-7, human hepatocellular carcinoma cell line HepG-2, human non-small cell lung carcinoma cell line A-549, and human colon adenocarcinoma cell line HT-29, resulting in IC50 values of 6.

Total synthesis and cytotoxic activity of stellatin
Journal of Asian Natural Products Research, 2011Stellatin (3,4-dihydro-8-hydroxy-7-hydroxymethyl-6-methoxyisocoumarin) (8), an extrolite of fungal genera Emericella and Aspergillus, was synthesized. Thus, Vilsmeier-Haack formylation of methyl ester of 3,5-dimethoxy-4-methylphenylacetic acid (1) to afford the formyl ester (2) followed sulfamic acid-sodium chlorite oxidation of the aldehydic function ...
