Disease relevance of Diaminopurine

 

High impact information on Diaminopurine

  • Somatic cell variants that arose in vivo as a consequence of genetic or epigenetic alterations abolishing Aprt function were selected and expanded in vitro by virtue of their resistance to 2,6-diaminopurine (DAP) [6].
  • We observed that p53 null mice produced about three times as many DAP-resistant fibroblast colonies than wild-type mice, but the frequency of DAP-resistant T lymphocyte colonies was not significantly changed [6].
  • Mitotic recombination, but not point mutation, partly accounted for the increase in the frequency of DAP-resistant fibroblasts [6].
  • Somatic cell variants that exhibited functional loss of the wild-type Aprt in vivo were recovered as APRT-deficient cell colonies after culturing in selection medium containing 2, 6-diaminopurine (DAP), an adenine analog that is toxic only to cells with APRT enzyme activity [7].
  • DAP-resistant (DAP(r)) fibroblast variants were recovered at a median frequency of 12 x 10(-5) from individual ears from progeny of crosses between mouse strains 129/Sv and C3H/HeJ [7].

Anatomical context of Diaminopurine

  • From five genetically heterozygous cell lines with two different genotypes (APRT*1/APRTQ0 and APRT*1/APRT*J), we have selected 48 clones resistant to 2,6-diaminopurine [18].
  • The (S)- and (R)-enantiomers of 9-(2-phosphonylmethoxypropyl) derivatives of adenine (PMPA) and 2,6-diaminopurine (PMPDAP) were evaluated for their inhibitory effect on HIV replication in several human cell systems, including natural peripheral blood lymphocytes (PBL) and freshly isolated monocyte/macrophages (M/M) [19].
  • Newly developed acyclic nucleoside phosphonates, derivatives of adenine and 2,6-diaminopurine bearing the 2-hydroxy-3-(phosphonomethoxy)propyl (HPMP) moiety at the N9-side chain (i.e., HPMPA and HPMPDAP, respectively) were screened for in vitro immunobiological activity, using mouse resident peritoneal macrophages and splenocytes [20].
  • T- and B-cells deficient in APRT enzyme activity were cloned from peripheral blood mononuclear cells using a selecting agent, 2,6-diaminopurine [21].
  • Thermal denaturation study showed that GPNA oligomers containing alternate D-backbone configuration bind sequence-specifically to DNA and, when incubated with mammalian cells, localized specifically to the endoplasmic reticulum (ER) [22].
