Metal-Free Coupling of Azoles with 2- and 3-Haloindoles Providing Access to Novel 2- or 3-(Azol-1-yl)indole Derivatives
摘要:
Thermal or microwave-mediated heating of 2- or 3-haloindoles with azoles (pK(a) < 8) provides a straightforward, metal-free, and environmentally friendly access to novel 2-(azol-1-yl)indoles. Furthermore, previously unknown 2,3-bis(azolyl-1-yl)indoles can be prepared from 2,3-dihaloindoles by sequential reaction with two distinct azoles. This operationally simple acid-catalyzed process delivers novel indole derivatives in fair to excellent yields and expands the chemical diversity of substitutions that can be introduced on this medicinally important scaffold.

New arylthioindole derivatives having different cyclic substituents at position 2 of the indole were synthesized as anticancer agents. Several compounds inhibited tubulin polymerization at submicromolar concentration and inhibited cell growth at low nanomolar concentrations. Compounds 18 and 57 were superior to the previously synthesized S. Compound 18 was exceptionally potent as an inhibitor of cell growth: it showed IC50 = 1.0 nM in MCF-7 cells, and it was uniformly active in the whole panel of cancer cells and superior to colchicine and combretastatin A-4. Compounds 18, 20, 55, and 57 were notably more potent than vinorelbine, vinblastine, and paclitaxel in the NCl/ADR-RES and Messa/Dx5 cell lines, which overexpress P-glycoprotein. Compounds 18 and 57 showed initial vascular disrupting effects in a tumor model of liver rhabdomyosarcomas at 15 mg/kg intravenous dosage. Derivative 18 showed water solubility and higher metabolic stability than 5 in human liver microsomes.
