Aminothiophene is a scaffold that is widely present in drugs and biologically active small molecules as chemical probes. In this study, 43 compounds sharing a 2-aminothiophenone-3-carboxylate (ATPC) scaffold, known to activate the ribonuclease L (RNase L), were synthesized and selected ATPCs showed enhancement of thermal stability of RNase L upon binding. Screening of antiproliferation activities against human cancer cell lines revealed that ATPCs represented by compounds 4l and 50 showed potent single-digit micromolar antiproliferation activity against human cancer cell lines. Compounds 4l and 50 exhibited time- and dose-dependent proliferation inhibition, induced cellular apoptosis measured by cleaved PARP and via flow cytometry, inhibited cell migration, and inhibited cell colony formation. Combining the results reported in this work, ATPCs were evaluated as potential anticancer agents mediated by RNase L-binding and apoptosis induction. The work contributes to the study on the polypharmacological properties of aminothiophene-containing small molecules.

Total synthesis of modified ellipticines 1c and 1f is described from 2-chloronicotinic acid and respectively 5-methoxy -indole and 5-azaindole in 11 to 13 steps with overall yields of 11% and 18%. A new route to 5-azaindole has also been developed. The synthetic strategy calls for frequent use of homo- and hetero aromatic metallation reactions necessiting resolution of problems associated with the presence of the pyridine ring. With respect to the numerous synthesis described in the litterature, the originality of this approach resides above all in the formation of ring C in basic medium.1 such conditions being dictated by the presence of the pyridine A ring in the case of 1f. Both synthesis have been extrapolated to produce several kilogrammes of final product. That first part deals with the preparation of the precursors.
