AbstractWith a view to finding new anticancer agents, different aryloxy groups were attached to C2 of the pyrimidine ring in 2-[3-phenyl-4-(pyrimidin-4-yl)-1H-pyrazol-1-yl]acetamide in five steps using methyl 3-methoxy-5-methylbenzoate as the key intermediate product. The anticancer activity of the synthesized compounds was tested on 60 cancer cell lines at 10 µM. One compound showed an appreciable

ROS1 protein is a receptor tyrosine kinase that has been reported mainly in meningiomas and astrocytomas, and until now, there is no selective inhibitor for this kinase. In this study, we illustrate for the synthesis of a highly potent and selective inhibitor for ROS1 kinase. The synthesized compound 1 was tested initially at a single dose concentration of 10 mu M over 45 different kinases. At this concentration, a 94% inhibition of the enzymatic activity of ROS1 kinase was observed, while the inhibition in activity was below 30% in all of the other kinases. The pyrazole compound 1 was further tested in a 10-dose IC50 mode and showed an IC50 value of 199 nM for ROS1 kinase. The compound 1 can be used as a promising lead for the development of new selective inhibitors for ROS1 kinase, and it may open the way for new selective therapeutics for astrocytomas.

A series of rationally designed ROS1 tyrosine kinase inhibitors was synthesized and screened. Compound 12b has showed good potency with IC50 value of 209 nM, which is comparable with that of the reference lead compound 1. Molecular modeling studies have been performed, that is, a homology model for ROS1 was built, and the screened inhibitors were docked into its major identified binding site. The docked poses along with the activity data have revealed a group of the essential features for activity. Overall, simplification of the lead compound 1 into compound 12b has maintained the activity, while facilitated the synthetic advantages. A molecular interaction model for ROS1 kinase and inhibitors has been proposed. (C) 2009 Elsevier Ltd. All rights reserved.
