Dr. Igor V. Alabugin
Igor V. Alabugin, Ph.D. is Associate Professor of
Chemistry and Biochemistry at Florida State University. His
research interests are at the intersection of photochemistry, organic
synthesis, and supramolecular chemistry with biochemistry and materials
science.
The major theme in his research is the use of light as a driving force
for chemical transformations. Light is not only a natural phenomenon
bringing life to Earth but also a unique chemical reagent. It is
environmentally clean and can be used to
promote highly selective and efficient chemical reactions. In his
research, he explores unique properties of light for the promotion of
new molecular and supramolecular transformations.
The ScienceDaily article
Chemists Kill Cancer Cells With Light-activated Molecules
describes the application of new molecules devoped in Dr. Alabugin’s
lab for the design of light-activated anticancer drugs.
“When one of the two strands of our cellular DNA is broken, intricate
cell machinery is mobilized to repair the damage,” he said. “Only
because this process is efficient can humans function in an environment
full of ultraviolet irradiation, heavy metals and other factors that
constantly damage our cells.”
However, a cell that sustains so much damage that both DNA strands are
broken at the same time eventually will commit suicide — a process
known as apoptosis.
“In our research, we’re working on ways to induce apoptosis in cancer
cells — or any cells that have harmful genetic mutations — by
damaging both of their DNA strands,” Alabugin said. “We have found that
a group of cancer-killing molecules known as lysine conjugates can
identify a damaged spot, or ‘cleavage’, in a single strand of DNA and
then induce cleavage on the DNA strand opposite the damage site. This
‘double cleavage’ of the DNA is very difficult for the cell to repair
and typically leads to apoptosis.” This research is described in a
2007 paper published in
Proceedings of the National Academy of
Sciences.
The possibility of triggering this transformation by light is
especially important because it will allow time- and space-controlled
activation of an anticancer drug. In other words, he would be able to
develop new drugs which start to work only in the right place and at
the right time upon irradiation with cell-permeable
photons.
