Functionalized thymidine derivatives as carriers for the γ-emitter technetium tricarbonyl moiety
چکیده انگلیسی

Nuclear medicine imaging of cell proliferation has gained broad interest in clinical oncology. A good tracer to image cell proliferation, possibly associated to tumour progression, should rapidly and specifically be incorporated into growing DNA. Following this idea, we have singled out thymidine as a potential biological carrier for delivery of the organometallic fragment [M(CO)3]+ (M = “cold” Re, γ-emitter 99mTc) to DNA. In the present paper we report the two-step synthesis of thymidine N-3 derivatives and their coordination complexes. Thymidine could be alkylated without protecting the sugar alcoholic functions. Methyl-2,2′-diaminodiethylamine thymidine derivative was quickly reacted with rhenium and technetium carbonyls in almost quantitative yield. The resulting 99mTc complex represents a convenient radiopharmaceutical for single photon emission tomography (SPECT).
