Chalcones are characterized by possessing an enone moiety between two arom. rings. A series of chalcone-like agents, in which the double bond of the enone system is embedded within a thiophene ring, were synthesized and evaluated for antiproliferative activity and inhibition of tubulin assembly and colchicine binding to tubulin. The replacement of the double bond with a thiophene maintains antiproliferative activity and therefore must not significantly alter the relative conformation of the two aryl rings. The synthesized compds. were found to inhibit the growth of several cancer cell lines at nanomolar to low micromolar concns. In general, all compds. having significant antiproliferative activity inhibited tubulin polymn. with an IC50 < 2 M. Several of these compds. caused K562 cells to arrest in the G2/M phase of the cell cycle.

Abstract
Chalcones are characterized by possessing an enone moiety between two arom. rings. A series of chalcone-like agents, in which the double bond of the enone system is embedded within a thiophene ring, were synthesized and evaluated for antiproliferative activity and inhibition of tubulin assembly and colchicine binding to tubulin. The replacement of the double bond with a thiophene maintains antiproliferative activity and therefore must not significantly alter the relative conformation of the two aryl rings. The synthesized compds. were found to inhibit the growth of several cancer cell lines at nanomolar to low micromolar concns. In general, all compds. having significant antiproliferative activity inhibited tubulin polymn. with an IC50 < 2 M. Several of these compds. caused K562 cells to arrest in the G2/M phase of the cell cycle.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
