    Abstract: PROBLEM TO BE SOLVED: To advantageously amplify a nucleic acid by using a polyamide-nucleic acid derivative/DNA primer having a nucleoside unit having 3'-hydroxyl group at one terminal, a thermostable polymerase enzyme and a usually required component. SOLUTION: One or more polyamide-nucleic acid derivatives (PNA)/DNA primers having at least one nucleoside unit having 3'-hydroxyl group at one terminal, a DNA polymerase derived from a microorganism such as the genus Thermus, Thermococcus or Pyrococcus as a thermostable DNA polymerase and a usually required component are used and reacted according to a method similar to a well-known amplifying method such as a polymerase chain reaction(PCR) and a ligase chain reaction (LCR) to thereby advantageously amplify the nucleic acid according to the method usable in diagnosis of viral infection or diseases or cancer diagnosis, etc.

    Abstract: A process is claimed for preparing peptide nucleic acid (PNA) oligomers of formula (I). Ro=H, 1-18C alkanoyl, 2-19C alkoxycarbonyl, 3-8C cycloalkanoyl (sic), 7-15C aroyl, 3-13C heteroaroyl or a gp. which enhances the intracellular uptake of the oligomer or interacts with a target nucleic acid during hybridisation; A and Q=amino acid residues; k and m=0-20; B=a nucleotide base, opt. in prodrug form; Qo=OH, NH2 or NHR''; R''=1-18C alkyl, 2-18C aminoalkyl or 2-18C hydroxyalkyl; n=1-50. The process comprises: (a) opt. coupling amino acids (Q') to a support of formula L-(Polymer) by solid-phase synthesis to give (Q')m-L-(Polymer), where L=a linking gp. contg. Qo in latent form and Q'=Q with optional side-chain protection; (b) coupling a cpd. of formula (II) to L-(Polymer) or (Q')m-L-(Polymer), where PG=a base-labile protecting gp. and B'=a nucleotide base with a protected exocyclic amino gp.; (c) removing PG; (d) repeating steps (b) and (c) n-1 times; (e) opt. coupling amino acids (A') to the prod. by solid-phase synthesis, where A'=A with optional side-chain protection, and introducing Ro if Ro is other than H; and (f) cleaving the PNA oligomer from the prod. of formula (III) and simultaneously or subsequently deprotecting B', A' and Q'. Also claimed are cpds. (II) and a process for preparing them.
