Abstract

Thymidylate synthase (TS) is responsible for catalysing the de novo biosynthesis of doexythymidine monophosphate and is a target for many anticancer drugs. A series of thymidylate synthase inhibitors (TSIs), synthesised in our laboratory, were submitted to primary anticancer screening by the National Cancer Institute (NCI). Four compounds, 3,3bis(4-methoxyphenyl)-1H, 3H-naphtho[1,8-cd]pyran-1-one (MR7), 6-chloro-3,3-bis(4-hydroxyphenyl)-]H,3H-naphtho[1,8cdjpyran-1-one (MR21), 3,3-bis(3-fluoro-4-hydroxyphenyl)IH,3H-naphtho[1,8-cd]pyran-l-one (MR35) and 6-bromo-3,3bis(3-chloro-4-hydro.xyphenyl)-1H,3H-naphtho[1,8-cd]pyran-l- one (MR36), passed the criteria and were automatically scheduled for evaluation against the full panel of 60 human tumour cell lines. In this study, the antiproliferative activity of the substances against SK-MEL-2 cells (from metastatic tissue) and SK-MEL-28 cells (from primary malignant melanoma cells) was investigated. Neutral Red uptake and the MTT test were performed to confirm the results of the NCI, and [H-3]thymidine incorporation was performed as a test of the proliferation rate. Our results indicated that compounds MR21 and MR36 were the most active agents and the [H-3]-thymidine test was the best in predicting toxicity against melanoma cells.
