Analogs of antiviral 9-(2-phosphonomethoxyethyl)adenine (PMEA,II), containing modified purine bases 1-deazaadenine (VII, 3-deazapurine (XI), 7-deaza-7-cyanoadenine (XIIIb) and 3-deazaguanine (XXIb) were prepared by alkylation of the heterocyclic bases with bis(2-propyl) 2-chloroethoxymethylphosphonate (V) in dimethylformamide in the presence of sodium hydride or cesium carbonate. The obtained protected derivatives were deblocked with bromotrimethylsilane to give the phosphonic acids. 3-DeazaPMEG (XXIb) is active against DNA viruses and exhibits a marked cytostatic effect against L-1210 leukemia.

The stoichiometry of the adducts formed between copper(II) bis(diethyldithiocarbamate) and pyridine in benzene, toluene, and chloroform and between 3-picoline, 4-picoline, and 3,4-lutidine in benzene are shown to be 1:1. The method employed is that of Scatchard using electron paramagnetic resonance studies.
