The human body contains a variety of different cell types that share a common genome, but differ in how they use the information encoded therein. Variation in molecular content exists even at the level of individual cells, and to provide deeper insight into complex cellular processes methods that permit analysis of each cell on its [...]
Quinone methides (QMs) are electrophilic intermediates that can be generated in vivo to alkylate DNA and function as anti-cancer drugs. Previously, DNA-QM conjugates have shown the ability to selectively deliver a QM to specific sequences of DNA. Peptide nucleic acids (PNAs) conjugates of QM are now being developed since PNA binds DNA with higher affinity [...]
This thesis is divided into two parts based on a total of 8 papers: Part 1: Synthesis, physicochemical and biochemical studies of chemically modified oligonucleotides and their duplexes and triplexes. Potency of the chromophore conjugated DNA oligonucleotides as antigene and antisense gene repressors was evaluated. The effect of geometry, bulk and ¥ð-electron density of a [...]
