First first-author publication by Ana. Original research from her PhD work that got highlighted in the Inside Cover of Journal of medicinal Chemistry!!

A new family of iridium half-sandwiches drug candidates has been designed that presents a structurally stable tether-ring in aqueous solution. the cationic iridium-based compounds display exceptionally potent anticancer activity. Iridium intracellular accumulation is remarkably high and the compounds unambiguously target the mitochondria, dissipating their membrane potential and triggering oxidative stress.

JJ Conesa*, AC Carrasco, V Rodríguez‐Fanjul, Y Yang, JL Carrascosa, P Cloetens, E Pereiro, AM Pizarro*. Angewandte Chemie International Edition 2020, 59, 1270-1278.

Amazing work with fantastic collaborators!!

Iridium half-sandwich complex [Ir(η51-C5Me4CH2py)(2-phenylpyridine)]PF6 is extraordinarily potent in a number of cancer cells lines. By using 3D cryo soft X-ray and fluorescence tomographies, correlatively on the same cryo-preserved cell, we have unambiguously and exclusively localized and quantified our new iridium anticancer agent in the cell mitochondria.

This is the first publication of the young AMP group at IMDEA Nano. Original research by Fran that got highlighted in the Inside Cover of Chemistry!!

Working on the design of organometallic pH-dependent switches to achieve in-tumour activation. In this article we show the potential of a series of ruthenium(II) complexes to become such pH-responsive anticancer drugs.
