Substrates efflux assay and P-gp ATPase activity assay were conducted to reveal the molecular mechanisms of P-gp inhibition, while SRB assay, cell cycle analyses and apoptosis analyses were performed to confirm the cancer MDR modulating effects.
Additionally, <i>in vitro</i> anticancer activity of the complexes were evaluated by SRB assay on selected cancer cell lines viz., HeLa (cervical), MIA-PA-CA-2 (pancreatic), MCF-7 (breast), Hep-G2 (Hepatoma), and SK-OV-3 (ovarian) which exhibited the superior cytotoxicity of complex [C<sub>31</sub>H<sub>35</sub>O<sub>4</sub>SeRuCl] as compared to other analogs on selective cancer phenotypes.Communicated by Ramaswamy H.

The synthesized pyrimidine scaffolds were screened for their antimicrobial activity by tube dilution method as well for antiproliferative activity (human colorectal (HCT116) cancer cell line) by SRB assay.
Antitumor activity for the prepared compounds against human breast adenocarcinoma (MCF-7), liver (HEPG2) and colon (HCT116) cancer cell lines was evaluated using SRB assay method.
They were examined for their cytotoxic effects using SRB assay on four cancer cell lines HepG2, HCT116, CACO and MCF-7 in addition to the non-cancerous human cell line.
Based on our previous work, the cytotoxicity of these derivatives were evaluated by the SRB method against 293T cell lines and three cancer cell lines: A549, Hela and MCF-7.
The biological activities of these molecules have been evaluated against various human cancer cell lines A549 (Lung adenocarcinoma cell line), MCF-7 (Breast carcinoma cell line), HCT-116 (Colon cancer cell line), and PC-3 (Prostate cancer cell line) through SRB assay.
