В результате исследования физико-химических свойств полученных комплексов показано, что они обладают достаточной устойчивостью в растворе для проведения исследований их биологической активности. В результате экспериментального определения антипролиферативной активности и внутриклеточной концентрации исследуемых комплексов показано, что увеличение гидрофобности входящих в состав тетразольного лиганда заместителей сопровождается увеличением липофильности комплексов и их внутриклеточной концентрации, что и приводит к росту их цитотоксической активности, и выявлено два соединения-лидера, а именно оксалатокомплексы платины с 5-амино-1-фенил- и 5-амино-2-трет-бутилтетразолами цис-конфигурации, обладающие наилучшим сочетанием антипролиферативной активности, липофильности и растворимости.</p></abstract><trans-abstract xml:lang="en"><p>Effective methods for preparation of tetrazole-containing biscaroxylate complexes of platinum (II) were developed and novel oxalate, malonate and succinate platinum (II) complexes with 1-R- and 2-R-5-aminotetrazoles (R = 1-CH3, 2-CH3, 1-C6H5, 2-t-C4H9), analogues of third-generation antitumor platinum drugs were prepared. Studies of the obtained complexes showed their stability in solution, which is sufficient for biological studies. Cell proliferation tests and bioanalytical studies showed that increasing the hydrophobicity of substituents at the tetrazole heteroring leads to an increase in the intracellular concentration of complexes followed by a growth of their cytotoxic activity. Two platinum oxalate complexes with 5-amino-1-phenyl- and 5-amino-2-tert-butyltetrazoles having cis-configuration were chosen as leader compounds featuring the best combination of the antiproliferative activity, lipophilicity, and solubility.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Komeda S., Takayama H., Suzuki T. et al. // Metallomics. 2013.
