  • Publication number: 20040157873
    Abstract: Compounds of the general formula (I) or (IA) in which X is H, Y is a leaving group, R1 and optionally also R3 preferably being an aromatic DNA binding subunit are prodrug analogues of duocarmycin. The compounds are expected to be hydroxylated at the carbon atom to which X is joined, by cytochrome P450, in particular by CYP1B1, expressed at high levels in tumours. The prodrug is expected to be activated preferentially in tumour cells, where it will act as a DNA alkylating agent preventing cell division.

  • Publication number: 20030008316
    Abstract: There is disclosed a compound of formula (I) wherein each of X1 and X2 are independently NH—A—NR1R2, and wherein A is A C2-8 alkylene and R1 and R2 are independently selected from hydrogen, C1-4 alkyl, C2-4 hydroxy-alkyl and C2-4 aminoalkyl, or R1 and R2 together form a C2-6 alkylene group which with the nitrogen atom to which R1 and R2 are attached forms a heterocyclic ring, or an N-oxide derivative thereof, and wherein the compound (I) or its N-oxide derivative is optionally in the form of an acid salt derived from an organic or inorganic acid. Also disclosed is a method of its production and its uses, including its use in analyzing a cell or biological material and detecting the emitted fluorescence signal.
