Synthesis, Spectroscopic Characterization, and Cytotoxic Evaluation of Pentasubstituted Ruthenocenyl Esters
摘要:
This article details the preparation and spectroscopic characterization of a focused library of new 18-electron ruthenocenyl complexes incorporating pentasubstituted Cp ester [C-5(CO2R)(5)](-) (for R = Me, Et, n-Pr, n-Bu, 2-Pr, 3-Pent, phenyl, and n-thiopropyl), carboxylic acid [C-5(CO2H)(5)](-), and carboxylate ligands [C-5(CO2H)(4)(CO2)](2-). Each complex has been characterized using Fourier transform IR and NMR spectroscopy and electrospray mass spectrometry, with single-crystal X-ray structural determinations reported for four complexes: [Ru(eta(5)-C5H4(C-5(CO2CH3)(5))(eta(5)-C-5(CO2CH3)(5))], K[Ru(eta(5)-C5H5)(eta(5)-C-5(CO2H)(4)(CO2))]center dot H2O [Ru(eta(5)-C5H5)(eta(5)-C-5(CO2H)(5))] center dot 2H(2)O, and [Ru(eta(5)-C5H5)(eta(5)-C-5(CO2C6H5)(5))]. Complexes were also evaluated for in vitro cytotoxic activity against a diverse panel of tumorigenic cell lines and a normal human cell line.
