The human type II topoisomerases are targeted by doxorubicin (Adriamycin), etoposide (Etopophos), and ellipticine.

Most of these drugs stabilize the covalent topoisomerase-DNA (cleaved) complex.

From the four possible transitions (n!p*, p!p*, n!s*, s!s*), only two can be elicited with light from the UV/Vis spectrum for some biological molecules: n!p* and p!p*. The n!s* and s!s* transitions are

energetically not within the range of UV/Vis spectroscopy and require higher energies.
