2,6-diaminopurine (2,6-DAP, also known as 2-aminoadenine) is a compound once used in the treatment of leukemia. As the Z base, it is found instead of adenine (A) in the genetic material of some bacteriophage viruses.

In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting 2,6-diaminopurine and related organic molecules, including the DNA and RNA components adenine and guanine, may have been formed extraterrestrially in outer space.
