Novel alpha-mannosidase inhibitors of the type (2R,3R,4S)-2-({[(1R)-2- hydroxy-1-arylethyl]amine}methyl) pyrrolidine-3,4-diol have been prepared and assayed for their anticancer activities. Compound 30 with the aryl group = 4-trifluoromethylbiphenyl inhibi ...
Tumors consist of cells whose growth and morphological characteristics are markedly different from those of normal cells. Observation of human and animal models argue that tumor development proceeds via a process formally analogous to Darwinian evolution, ...
Changes in the glycosylation pattern of cellular glycoproteins constitute a hallmark in human cancer and influence tumour progression, suggesting that inhibitors of selected glycosidases may control cancer invasion. Following the studies on swainsonine, a ...
In recent years, ruthenium-based antitumour drugs have emerged as an attractive alternative to cisplatin, exhibiting both excellent activity in tumours where cisplatin is of limited use and low general toxicity, leading to reduced side effects. Two rutheni ...
A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
A number of cyclo-β-tripeptides and their linear precursors were subjected to primary biol. evaluation for cancer-cell growth inhibition (one-dose, three-cell essay), and the five most active ones were then tested in the anti-tumor screen of the National C ...
Stimulation of the macrophage-like cell line THP-1 with the phorbol ester phorbol 12-myristate 13-acetate (PMA) resulted in differentiation into cells with many features of macrophages. This differentiation was accompanied by transcriptional activation of ...
Organometallic half-sandwich complexes based on ruthenium with aminomethyl-substituted 3-hydroxy-2-pyridone ligands exist in aqueous solution as monomeric O,O′-chelate complexes or trimeric metallamacrocycles depending upon the pH. We hypothesized that adm ...
