Several excited singlet electronic states of purine nucleobases and related derivatives have been calculated using high-level multireference perturbation theory methods. Purine derivatives with one or two amino or carbonyl groups substituted at positions C(2) and/or C(6) of the purine ring

A positive charge migrates along DNA mainly via a series of short-range charge transfer (CT) processes between G-C base pairs, which have relatively high HOMO levels. As such, the CT efficiency sharply decreases with the insertion of A-T base pairs
A Boc-protecting group strategy for Fmoc-based PNA (peptide nucleic acid) oligomerization has been developed for thymine, 2,6-diaminopurine (DAP) and 2-aminopurine (2AP). The monomers may be used interchangeably with standard Fmoc PNA monomers. The DAP monomer was incorporated into a PNA

FT-IR and FT-Raman spectra of 2,6-diamino purine (DAP) and 6-methoxy purine (MP) have been recorded in the regions of 4000-400cm(-1) and 3500-100cm(-1), respectively. The spectra were interpreted with the aid of normal coordinate analysis following full structure optimizations and force
Alkyldiamine-tethered derivatives of 2,6-diaminopurine, ethylenediamine-N9-propyl-2,6-diaminopurine, L1, and ethylenediamine-N9-ethyl-2,6-diaminopurine, L2, react with Pd(II) to give N3-coordinated complexes. However, the exact nature of the resulting complex is dependent on the reaction conditions. With PdCl(2)(MeCN)(2) in MeCN/H(2)O the expected [PdCl(N3-2,6-DAP-alkyl-en)](+) complex, 1, is
