WebDec 1, 2024 · Iron is the most abundant element on earth (including crust and inner core), and the 4th most abundant metal on the earth's crust [ 1 ]. Its electron configuration allows formation of stable ferrous (Fe +2) or ferric (Fe +3) ions. Iron readily forms complexes with organic molecules, and this has immense biological implications. WebThe free radical mechanism to treat certain types of cancers extends beyond enediynes. Tirapazamine generates a free radical under anoxic conditions instead of the trigger mechanism of an enediyne. The free radical then continues on to cleave DNA in a similar manner to 1,4-didehydrobenzene in order to treat cancerous cells.
