摘要:
Compounds of formula (I) or (II), wherein X represents H, C1-6 alkyl or C1-6 alkoxy, said alkyl or alkoxy being optionally substituted with one or more groups; a is 0,1,2,3 or 4; Y represents H or C1-6 alkyl; 1, 2 or 3 of the members Z of the 5-membered aromatic ring are independently selected from -O-, -S-, -N= or -NR-, where R is H or C1-6 alkyl optionally substituted with one or more of groups; and E represents a moiety such that EH is an amine; provided that in formula (I) if a = 0 then Y≠H, are provided along with a method of selecting desired protecting groups by measuring the fragmentation rates of compounds of formula (I) or (II) when the nitro group is selected.
摘要:
The present invention relates to DNA-targeted 1,2,4-benzotriazine- 1,4-dioxides and related analogues, to their preparation, and to their use as hypoxia-selective drugs and radiosensitizers for cancer therapy, both alone or in combination with radiation and/or other anticancer drugs.
摘要:
The invention provides novel prodrug compounds comprising a kinase inhibitor and a reductively-activated fragmenting aromatic nitroheterocycle or aromatic nitrocarbocycle trigger, where the compound carries a positive charge. In preferred embodiments, the compounds are of Formula I: where: X is any negatively charged counterion; R 1 is a group of the formula —(CH 2 ) n Tr, where Tr is an aromatic nitroheterocycle or aromatic nitrocarbocycle and —(CH 2 ) n Tr acts as a reductively-activated fragmenting trigger; and n is an integer from 0 to 6; R 2 , R 3 and R 4 may each independently be selected from aliphatic or aromatic groups of a tertiary amine kinase inhibitor (R 2 )(R 3 )(R 4 )N, or two of R 2 , R 3 , and R 4 may form an aliphatic or aromatic heterocyclic amine ring of a kinase inhibitor, or one of R 2 , R 3 and R 4 may be absent and two of R 2 , R 3 and R 4 form an aromatic heterocyclic amine ring of a kinase inhibitor. The compounds of the invention are useful in treating proliferative diseases such as cancer.
摘要:
The present invention provides a simplified set of characteristics that can be used to select 1,2,4 benzotriazine 1,4 dioxide compounds (TPZ analogues) with therapeutic activity against hypoxic cells in human tumour xenografts, and to further provide a novel class of 1,2,4-benzotriazine-1,4-dioxides (TPZ analogues) with predicted in vivo activity against tumours, to their preparation, and to their use as hypoxia-selective cytotoxic drugs and radiosensitizers for cancer therapy, both alone or in combination with radiation and/or other anticancer drugs.
摘要:
The invention relates to novel tricyclic 1,2,4-triazine-1-oxides and novel tricyclic 1,2,4-triazine-1,4-dioxides of formula: (I); and to related analogues, to their preparation, and to their use as hypoxia-selective drugs and radiosensitizers for cancer therapy, both alone or in combination with radiation and/or other anticancer drugs.
摘要:
The present invention provides compounds of formulae (I) and (II), where X in formula (I) represents a group cleavable by a nitroreductase or carboxypeptidase enzyme. Enzymatic activation of the compounds provide pharmaceutical compounds which may be used for the treatment of neoplastic disease.
