Application

Polyadenylic acid-Polyuridylic acid (polyAU) is a double stranded homodimer studied for potential therapeutic activity, especially when coupled with radiotherapy. PolyA/U is used in comparative physiochemical studies with other duplex and single-stranded polymers such as poly-A and poly-U.

The interaction of coralyne with poly(A)*poly(U), poly(A)*2poly(U), poly(A) and poly(A)*poly(A) is analysed using spectrophotometric, spectrofluorometric, circular dichroism (CD), viscometric, stopped-flow and temperature-jump techniques. It is shown for the first time that coralyne induces disproportionation of poly(A)*poly(U) to triplex poly(A)*2poly(U) and
