The synthesis of new isogranulatimide analogues, their inhibitory activities toward the Checkpoint 1 kinase (Chk1), and their in vitro cytotoxicities toward four tumor cell lines (one murine L1210 leukemia, and three humancell lines: DU145 prostate carcinoma, A549 non-smallcelllungcarcinoma, and HT29 colon carcinoma) are described. The affinity for DNA of some representative compounds and their
An efficient four step synthesisfrom commercial indoles of isogranulatimide analogues is reported. In the new compounds, the imidazole moiety is replaced by a pyrrole unit, the indolepart is substituted or not in 5-position and the nitrogen of the imide moiety bears or not a methyl substituent.
