	abstract = {The water-soluble Ru-II acetylacetonato-sulfoxide complexes, cis-Ru(acac)(2)(DMSO)(2) (1) and Ru(acac)(2)(meso-BESE) (2), were synthesized (BESE = 1,2-bis(ethylsulfinyl)ethane = EtS(O)(CH2)(2)S(O)Et). Both complexes were characterized by H-1 and C-13{H-1} NMR, UV-Vis, and IR spectroscopies, as well as MS, elemental analysis, solution conductivity, and cyclic voltammetry, while the molecular structure of 2 was determined also by X-ray crystallography. All sulfoxide ligands are S-bonded. The complexes were tested against human breast cancer cells (MDA-MB-435S) using an in vitro MTT assay, a colorimetric determination of cell viability; IC50 values of >2000 and 1500 +/- 100 muM were determined for 1 and 2, respectively, while cisplatin exhibits an IC50 value of 30 +/- 5 muM.

	abstract = {A total of 15 samples (crude extracts and pure secondary metabolites) obtained from marine invertebrates collected from the offshore waters of British Columbia, Papua New Guinea, and Sri Lanka have previously been shown to exert cytotoxic activity in the in vitro L1210 leukemic bioassay. We screened these metabolites for in vitro cytotoxic activity against the drug-sensitive breast-tumor cell lines MCF-7, T-47D, ZR-75- 1, and MDA-MB23 1; the multidrug-resistant and P-glycoprotein (Pgp)-positive breast-tumor cell lines MCF-7 Ad(r) and MDA-Al(r); and normal and malignant human breast epithelial cells (HBEC) in primary culture. Eight samples exhibited significant [drug concentration resulting in a 50\% decrease in cell growth as compared with controls (ED50), <25-mu-g/ml] dose-dependent cytotoxicity against the drug-sensitive cell lines; the ED50 values were as low as 0.004-mu-g/ml. Five of the eight samples exhibited significant cytotoxicity against the multidrug-resistant cell lines; the ED50 values were as low as 0.0006-mu-g/ml. Incubation of MCF-7 Ad(r) cells with varying concentrations of compounds in the presence of Adriamycin demonstrated that none of the compounds tested interfered with Pgp function. Results obtained using HBEC in primary culture showed a wide range of chemosensitivities for a given drug against tissue taken from different patients, demonstrating the uniqueness of the response of different individuals to chemotherapy.},
