Binding of Indanocine to the Colchicine Site on Tubulin Promotes Fluorescence, and Its Binding Parameters Resemble Those of the Colchicine Analogue AC
(AMER CHEMICAL SOC, 2009-02-24)Indanocine, a synthetic indanone, has shown potential antiproliferative activity against several tumor types. It is different from many other microtubule-disrupting drugs, because it displays toxicity toward multidrug ... -
Contribution of p53-mediated Bax transactivation in theaflavin-induced mammary epithelial carcinoma cell apoptosis
(SPRINGER, 2008-06)Theaflavins, the bioactive flavonoids of black tea, have been demonstrated to inhibit proliferation and induce apoptosis in a variety of cancer cells. However, the contribution of p53 in mammary epithelial carcinoma cell ... -
Electronic transport, density of states and ground state properties of Li- In binary alloy
(ELSEVIER SCIENCE BV, 2008-10-01)The electronic transport properties of Li-In binary alloy have been studied by Harrison's first principle pseudopotential technique. The Percus-Yevik hard sphere model is used to compute the partial structure factors Sij/(k) ... -
