The antitumor activity of the organometallic ruthenium(II)-arene complexes, RuCl(2)(eta(6)-arene)(PTA), (arene = p-cymene, toluene, benzene, benzo-15-crown-5, 1-ethylbenzene-2,3-dimethylimidazolium tetrafluoroborate, ethyl benzoate, hexamethylbenzene; PTA = 1,3,5-triaza-7-phosphaadamantane), abbreviated RAPTA, has been evaluated. In vitro biological(More)
The study of metal complexes for the treatment of cancer diseases has resulted in the identification of some unique properties of ruthenium-based compounds. Among these inorganic-based agents, two of them, namely the ruthenium(III) drugs NAMI-A and KP1019 have undertaken with some success the clinical evaluations of phase I and preliminary phase II trials(More)
NAMI-A is a ruthenium-based compound with selective anti-metastasis activity in experimental models of solid tumours. We studied whether this activity was dependent on anti-angiogenic ability of NAMI-A. We thus investigated its in vitro effects on endothelial cell functions necessary for angiogenesis to develop, as well as its in vivo effects in the chick(More)
The antimetastatic ruthenium complex imidazolium trans-imidazoledimethylsulfoxide-tetrachlorouthenate (NAMI-A) is tested in the B16 melanoma model in vitro and in vivo. Treatment of B6D2F1 mice carrying intra-footpad B16 melanoma with 35 mg/kg/day NAMI-A for 6 days reduces metastasis weight independently of whether NAMI-A is given before or after surgical(More)
BACKGROUND This phase I/II study determined the maximal tolerable dose, dose limiting toxicities, antitumor activity, the pharmacokinetics and pharmacodynamics of ruthenium compound NAMI-A in combination with gemcitabine in Non-Small Cell Lung Cancer patients after first line treatment. METHODS Initial dose escalation of NAMI-A was performed in a 28 day(More)
Imidazolium-trans-dimethylsulfoxideimidazoletetrachlororuthenate (NAMI-A) is a ruthenium compound effective on solid tumor metastases. In this study, we evaluated the effects of different routes of administration of NAMI-A on the distribution to primary tumor, lungs and kidneys in BD2F1 hybrids with Lewis lung carcinoma or in CBA inbred mice with MCa(More)
The effects of NAMI-A (imidazolium trans-imidazoledimethyl sulfoxide-tetrachlororuthenate) are compared with cisplatin on tumor cells cultured in vitro at doses of 1 to 100 microM and on tumor metastases in vivo at maximum tolerated doses. Using mouse tumors that metastasize to the lungs, NAMI-A given i.p. for 6 consecutive days at 35 mg/kg/day, was(More)
NAMI-A, i. e. (imH)[trans-RuCl(4)(dmso-S)(im)] (im = imidazole, dmso = dimethylsulfoxide), is a Ru(III) complex that, after extensive preclinical investigations that evidenced its remarkable and specific activity against metastases, has recently and successfully completed a Phase I trial (first ruthenium complex ever to reach clinical testing). This review(More)
The discovery of new metal-based antitumour drugs, whether cisplatin derivatives or those based on other metals, has been largely based on cell viability assays (IC50 values) and compounds that bind to DNA. This approach has been applied for more than 30 years during which time very few new drugs have entered clinical use. In this article we discuss what(More)
