Arylureas derived from colchicine: Enhancement of colchicine oncogene downregulation activity
Elsevier (2018-04-25)Our efforts to get therapeutically useful colchicine derivatives for the treatment of cancer have led us to synthetize and biologically evaluate twenty-seven N,N′-disubstituted ureas containing a colchicine moiety and an ... -
Design and Synthesis of Pironetin Analogue/Colchicine Hybrids and Study of Their Cytotoxic Activity and Mechanisms of Interaction with Tubulin
American Chemical Society (2014-11)We here report the synthesis of a series of 12 hybrid molecules composed of a colchicine moiety and a pironetin analogue fragment. The two fragments are connected through an ester–amide spacer of variable length. The ... -
Effects on tubulin polymerization and down-regulation of c-Myc, hTERT and VEGF genes by colchicine haloacetyl and haloaroyl derivatives
Elsevier (2018-04-25)Several colchicine analogues in which the N-acetyl residue has been replaced by haloacetyl, cyclohexylacetyl, phenylacetyl and various aroyl moieties have been synthesized. The cytotoxic activities of the synthesized ... -
Inhibitory effect of pironetin analogue/colchicine hybrids on the expression of the VEGF, hTERT and c-Myc genes
Elsevier (2015-08)A small group of hybrid molecules composed of a colchicine moiety and a pironetin analogue fragment have been investigated for their ability to inhibit the expression of the VEGF, hTERT and c-Myc genes. The VEGF gene is ... -
Interactions of long-chain homologues of colchicine with tubulin
Elsevier (2017-01)Several colchicine analogues in which the N-acetyl residue has been replaced by aliphatic, straight-chain acyl moieties, have been synthesized. These compounds show high cytotoxic activity at the nanomolar level against ... -
N-alpha-Aminoacyl Colchicines as Promising Anticancer Agents
Bentham Science Publishers (2020-12-29)Background: In the last years, many efforts have been made to find colchicine derivatives with reduced toxicity. Additionally, the deregulation of amino acid uptake by cancer cells provides an opportunity to improve ... -
