“…In fact, not only endogenous ligands but also exogenous compounds bind to HSA, e.g., commonly used drugs such as warfarin, camptothecins and inorganic polymers such as polyoxometalates [7][8][9]. The binding mechanism has been investigated, e.g., arazine, ochratoxin, methyl parathion, and arsenic [10][11][12][13]. Concerning to DNA, whose conformation and sequence preference is critical to replication, transcription and DNA chromatin compaction [14], it is reported that DNA is subject to the effect of organic chemicals, too, whether it is endogenous ligands or exogenous compounds.…”
