Abstract

To solve the problem of delivering pharmacologically promising 3ʹ,5ʹ-cyclic diadenosine monophosphate (cyclo-diAMP) to target cells in humans and animals, the complexes of the above-mentioned dinucleotide with natural polymer – chitosan were originally synthesized by ionotropic gelation technique. It was found that the binding degree of cyclo-diAMP to this biopolymeric carrier reaches 60 %; wherein the capacity of the obtained complexes with respect to the dinucleotide is 800–860 µg/mg of the produced complex. Cyclo-diAMP has also been shown to elute from the chitosan complex to the citrate-phosphate buffer (pH 7.4) up to 36 % by 21 hours. The obtained results testify in favor of potential application of cyclodiAMP complex with chitosan for prolonged delivery of the studied cyclic dinucleotide to target cells.
