Synthesis and study of nucleic acids interactions of novel monomethine cyanine dyes
摘要:
Six asymmetric monomethine cyanine dyes have been synthesized and their spectral characteristics and interaction with double stranded (ds)DNA have been investigated for their prospective use as fluorescent markers in molecular biology. Therefore, the non-covalent binding of the compounds with dsDNA was explored. Apart from the fluorescence spectroscopy, the study includes UV/Vis spectrophotometry and circular dichroism spectroscopy, as well as the thermal melting experiments. Although the compounds show relatively low binding affinity toward dsDNA and do not have intrinsic fluorescence, in the presence of dsDNA they exhibited considerable enhancement in fluorescence intensity. Therefore the studied dyes show interesting platform for future modifications directed toward more sequence selective derivatives. The compound with the highest affinity toward dsDNA showed interesting anti-proliferative potential and specificity. (C) 2011 Elsevier Ltd. All rights reserved.
In the quest for sustainable and efficient synthetic methodologies within medicinal chemistry, the synthesis of carbamates and their derivatives holds a pivotal role due to their widespread application in bioactive compounds. This investigation unveils a novel methodology for the straightforward transformation of Boc-protected amines into carbamates, thiocarbamates, and ureas, utilizing tert-butoxide
