Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: (pyrimidine nucleoside or adenine)(out) + Na+(out) = (pyrimidine nucleoside or adenine)(in) + Na+(in). Catalysis of the transfer of adenine, 6-aminopurine, from one side of a membrane to the other. Catalysis of the transfer of purines, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, from one side of a membrane to the other. Catalysis of the transfer of xanthine from one side of a membrane to the other. Xanthine (2,6-dihydroxypurine) is a purine formed in the metabolic breakdown of guanine, but is not present in nucleic acids. Catalysis of the transfer of a nucleobase, any nitrogenous base that is a constituent of a nucleoside, nucleotide, or nucleic acidfrom one side of a membrane to the other. Catalysis of the transfer of guanine, 2-amino-6-hydroxypurine, from one side of a membrane to the other. Catalysis of the transfer of nucleobases, nucleosides, nucleotides and nucleic acids from one side of a membrane to the other.
