  Tyrosine Kinase Inhibitors. 3. Structure-Activity Relationships for Inhibition of Protein Tyrosine Kinases by Nuclear-Substituted Derivatives of 2,2'-Dithiobis(1-methyl-N-phenyl-1H-indole-3-carboxamide)

  摘要：

  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 IC(50)s in the range 2-25 mu M, 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.

  This work presented the efficient intramolecular aromatic C–H insertion of diazoacetamide. The 1a–1o diazo compounds (except for 1k) were converted into their corresponding oxindoles via an intramolecular C–H insertion reaction in the presence of a Ru catalyst. The Ru-Pheox catalyst was shown to be highly efficient in this transformation in terms of the regioselectivity, producing the desired products

• Solid Phase Approaches to <i>N</i>-Heterocycles Using a Sulfur Linker Cleaved by SmI₂

  A sulfur HASC (α-hetero-atom substituted carbonyl) linker has been utilized in solid-phase approaches to oxindoles and tetrahydroquinolones. The route to oxindoles employs the first Pummerer cyclizations on solid phase, whereas the route to tetrahydroquinolones involves a microwave-assisted Heck reaction followed by a Michael cyclization. In both cases, the linker is cleaved in a traceless fashion

  硫HASC（α-杂原子取代的羰基）连接基已用于固相合成羟吲哚和四氢喹诺酮。到吲哚的途径是在固相上首先进行Pummerer环化反应，而到四氢喹诺酮的途径则涉及微波辅助的Heck反应，然后进行Michael环化反应。在这两种情况下，接头都通过碘化sa（II）的电子转移以无痕方式裂解。这些路线说明了接头系统与多种反应类型的兼容性及其在文库合成中的效用。

  A novel method for the synthesis of oxindoles is described. In the presence of catalytic palladium acetate and 2-(di-tert-butylphosphino)biphenyl, α-chloroacetanilides are converted to oxindoles in good to excellent yields with high functional group compatibility using triethylamine as a stoichiometric base. The cyclization is highly regioselective, obviating the need for prefunctionalized arenes.
