Abstract:
Novel flexible oligodeoxynucleotides containing (S)-1-(2,3-dihydroxypropyl)thymine or 2',3'-seco-thymidine nucleoside analogues were synthesized on an automated DNA-synthesizer. Oligodeoxynucleotides with one, two or three acyclic nucleosides incorporated in the middle or in the ends of 17-mers have been evaluated. 3'-End-modified oligomers were significantly stabilized towards 3'-exonucleolytic degradation compared to unmodified analogues and showed acceptable hybridization properties as measured by UV experiments. For oligodeoxynucleotide analogues containing the three novel acyclic monomers in the middle, a more pronounced reduction in duplex stability was observed. All oligodeoxynucleotides containing acyclic nucleoside analogues made so far are evaluated with respect to stability towards 3'-exonucleolytic degradation and hybridization properties.

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
ATP and Macromolecule Synthesis
Most macromolecules are composed of single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.
