    摘要: Compounds of the general formula:
    wherein R is H, an acyl group or a hydrocarbyl group containing up to 6 carbon atoms, have cytotoxic activity against several tumours. The 4-hydroxylamino compound can be obtained directly from the corresponding 2,4-dinitro compound by selective chemical reduction or by the action of a nitroreductase obtainable from Walker tumour cells. The 2,4-dinitro compound is substantially devoid of cytotoxic activity except in relation to Walker tumour cells and hence can act as a prodrug in regimes where a prodrug is localised in vivo in the regions of a tumour to be treated and is then activated to the cytotoxic 4-hydroxylamino compound under the influence of the enzyme.

    摘要: The present invention provides compounds of general formula (I) wherein each R1, which may be the same or different, is hydrogen, alkyl or an electron withdrawing group, R2 is hydrogen, alkyl or an electron withdrawing organic group. The compounds are analogues of trimelamol which have comparable activity but enhanced stability, and are useful as anticancer agents, particularly against ovarian carcinomas.

    摘要: Compounds of the formula:

    wherein R³ is hydrogen, alkyl or hydroxymethyl, and R¹ and R² are hydrogen, alkyl or an electron withdrawing organic group containing at least two carbon atoms, at least one of R¹ and R² being an electron withdrawing group, and with the proviso that: when R³ is hydroxymethyl, R¹ and R² are electron withdrawing organic groups; are useful in the treatment of cancers, particularly cis-platin resistant ovarian cancer. The new compounds are obtainable by reacting formaldehyde with an intermediate of formula:

    wherein R 3a and R 3b are hydrogen, alkyl or hydroxymethyl, but not both hydroxymethyl, and
    R¹ and R² are hydrogen, alkyl or an electron withdrawing organic group containing at least two carbon atoms, and at least one of R¹ and R² is an electron-withdrawing organic group and where necessary, converting any N-hydroxy-methoxymethyl substituents to N-hydroxymethyl by treatment with an aqueous medium.
