Synthesis and Biological Evaluation of α-Tubulin-Binding Pironetin Analogues with Enhanced Lipophilicity
2013
Financial support has been granted to M. C. by the Spanish Ministry of Education and Science (project numbers CTQ2008-02800 and CTQ2011-27560), by the Conselleria d'Empresa, Universitat i Ciencia de la Generalitat Valenciana (ACOMP09/113) and by the BANCAJA-UJI Foundation (P1-1B2002-06, P1-1B-2008-14 and PI-1B2011-37). The biological work has been supported in part by grants from the Spanish Ministry of Education and Science (grant number BIO2010-16351) and from the Comunidad de Madrid (grant number S2010/BMD-2457 BIPEDD2-CM), both to J. F. D. We further thank the Matadero Municipal Vicente de Lucas in Segovia for providing the calf brains, which were the source of tubulin.
Design and synthesis of pironetin analogue/colchicine hybrids and study of their cytotoxic activity and mechanisms of interaction with tubulin
2014
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 cytotoxic activities of these compounds and their interactions with tubulin have been investigated. Relations between the structure and activity are discussed. Since the spacer is not long enough to permit a simultaneous binding of the hybrid molecules to the colchicine and pironetin sites on tubulin, a further feature investigated was whether these molecules would interact with the latter through the pironetin end (irreversible covalent binding) or through the colchicine end (…
