N-Substituted oxindoles and 2-indolinethiones can be prepared by lithiation of carboxyl protected N,2-dimethylanilines followed by quenching with CO2 or CS2 respectively. 2-Indolinethione derivatives are also available via demethylation of 2-methylthioindoles, which are prepared by lithiation of N-substituted indoles and treatment with dimethyl disulfide.

A series of indole-substituted 2,2'-dithiobis(1-methyl-N-phenyl-1H- indole-3-carboxamides) were prepared and evaluated for their ability to inhibit the tyrosine kinase activity of both the epidermal growth factor receptor (EGFR) and the nonreceptor pp60(v-src) tyrosine kinase. The compounds were synthesized by conversion of appropriate 1-methyloxindoles to 1-methyl-2-indolinethiones with P2S5 followed by subsequent reaction with NaH and phenyl isocyanate and oxidative dimerization of the resulting 2,3- dihydro-N-phenyl-2-thioxo-1H-indole-3-carboxamides. The parent compound and many of the substituted analogues were moderately potent inhibitors of both kinase enzymes, but no clear relationships were seen between substitution on the indole ring and inhibitory activity. While 4-substituted compounds were generally inactive, 5-substituted derivatives with electron-withdrawing groups showed inhibitory activity. However, none of the substituted compounds showed significantly better activity than the unsubstituted parent compound. There was generally a good correlation between activity against the EGFR and pp60(v-src) kinases, but several compounds did show some specificity (>20- fold) of inhibition; 5-Cl and 5-Br derivatives preferentially inhibited pp60(v-src), while the 5-CF3 compound preferentially inhibited EGFR. Selected compounds from the series were found to inhibit the growth of Swiss 3T3 fibroblasts with IC50s in the range 2-25 μM, the most active being 4- substituted derivatives. The compounds inhibited bFGF-mediated protein tyrosine phosphorylation in intact cells more effectively than EGFR- or PDGF- mediated phosphorylation.
