Flexible synthesis of isomeric pyranoindolones and evaluation of cytotoxicity towards HeLa cells

A hybrid pharmacophore approach for the synthesis of isomeric pyranoindolones was achieved by employing gold(III) chloride-catalyzed cycloisomerization of alkyne-tethered indole carboxylic acids in good to excellent yield. All the synthesized compounds were evaluated for their tumor cell growth inhibitory activity against human cervix adenocarcinoma (HeLa) which revealed that three compounds exhibited activity comparable with the standard cis-platin (IC50 = 0.08 μM). Molecular docking of all the compounds in Vaccinia H1-Related (VHR) Phosphatase receptor also supported that compound 7d as the most active with a free energy of binding as ?8.27 kcal/mol.

Gold(III) chloride catalyzed regioselective synthesis of pyrano[3,4-b]indol-1(9H)-ones and evaluation of anticancer potential towards human cervix adenocarcinoma

A highly regioselective synthesis of pyrano[3,4-b]indol-1(9H)-ones via gold(III) chloride catalyzed cycloisomerization of 3-ethynyl-indole-2-carboxylic acid was achieved in good to excellent yields. These compounds were screened for their in vitro cytotoxicity against human cervical (HeLa) cell lines. Out of ten compounds, three compounds (7d, 7e and 7j) showed comparable proliferation inhibitory activity against the standard drug cisplatin. Compound 7d was found to be the most efficacious with IC50 value of 0.22 μM.

SYNTHESIS AND CERTAIN PROPERTIES OF ACETYLENYLINDOLES

A group of new acetylenic derivatives of indole was synthesized by condensation of 2- and 3-iodoindoles with terminal acetylenes. 3-Iodoindole unsubstituted at the heteroatom is distinguished by an increased tendency to undergo deiodination under the reac
