title: [Toxicity and antitumoral activity of two new complex compounds of rhenium].
abstract: Toxicity and antitumor action of two new complex compounds of rhenium (K2 [ReCl6] and [ReCl(4).2C6H4N2]) were investigated. LD50 of K2 [ReCl6], i.v., was 136 +/- 37 mg/kg; i.p.,--272 +/- 74 mg/kg. LD50 of [ReCl(4).2C6H4N2], i.v., was 543 +/- 148 mg/kg; i.p., 600 mg/kg was tolerable. Single maximum tolerable dose of 200 mg/kg K2 [ReCl6], i.p., did not influence the growth of ascitic tumor of Ehrlich, nor did daily intravenous dose of 50 mg/kg inhibit solid tumor of Ehrlich. No inhibition by [ReCl(4).2C6H4N2] was registered when 25 or 50 mg/kg were administered.
