摘要:
Nitroaniline-based unsymmetrical mustards of the general formula (I) are provided, together with methods of preparation and methods for their use as prodrugs for gene-dependent enzyme prodrug therapy (GDEPT) and cell ablation therapy in conjunction with nitroreductase enzymes as hypoxia selective cytotoxins and as anticancer agents.
摘要:
This invention relates to a class of heterocycles and their metal complexes, and is particularly concerned with the use of these compounds in the preparation of prodrugs or as prodrugs that may be activated under hypoxic conditions by enzymes or by therapeutic ionising radiation, in the treatment of cancer. The invention also relates to the use of these heterocycles and the corresponding metal complexes in the preparation of medicaments and to compositions including the heterocycles or their metal complexes and to methods for preparing these compounds.
摘要:
A compound which is a 6-substituted seco indoline of the formula (I): wherein: X is halogen or OSO2R where R represents H or C1-5 alkyl optionally substituted with from 1 to 4 hydroxyl, acid (COOH) or amino groups which amino may be optionally substituted by one or two C1-5 alkyl groups; Y is N02, N3, NHOH, NHR, NRR, N═NR, N(O)RR, SR or SSR, where R is defined as above, but that in the case where Y is SSR or N═NR, then R can also be another moiety of formula (I); or Y is a group of formula:
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; R1 is a group of the formula —(CH2)nTr, where Tr is an aromatic nitroheterocycle or aromatic nitrocarbocycle and —(CH2)nTr acts as a reductively-activated fragmenting trigger; and n is an integer from 0 to 6; R2, R3 and R4 may each independently be selected from aliphatic or aromatic groups of a tertiary amine kinase inhibitor (R2)(R3)(R4)N, or two of R2, R3, and R4 may form an aliphatic or aromatic heterocyclic amine ring of a kinase inhibitor, or one of R2, R3 and R4 may be absent and two of R2, R3 and R4 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 invention provides kinase inhibitors of Formula I: wherein either: (1) R1 is H, and (a) R2 is (3-chlorobenzyl)oxy-and R3 is chloro; (b) R2 and R3, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole; (c) R2 is 2-pyridinylmethoxy and R3 is chloro; (d) R2 and R3 are both chloro; (e) R2 is chloro and R1 is bromo; (f) R2 and R3 are both bromo; (g) R2 is fluoro and R3 is ethynyl; (h) R2 is chloro and R3 is ethynyl; (i) R2 is bromo and R3 is ethynyl; (j) other than when R1 is in the 3-position in combination with R3, in the 4-position, R2 is bromo and R3 is fluoro; (k) R2 is 2-pyridinylmethoxy and R3 is fluoro; or (l) R2 is 2-pyridinylmethoxy and R1 is bromo; or (2) at least one of R1, R2 and R3 is selected from benzyloxy, 3-chlorobenzyloxy and 2-pyridinylmethoxy and when at least one of R1, R2 and R3 is not benzyloxy, 3-chlorobenzyloxy or 2-pyridinylmethoxy, each of the others is independently selected from H, halogen, and C2-C4 alkynyl, with the proviso that when one of R1, R2 and R3 is benzyloxy or 2-pyridinylmethoxy, the other two of R1, R2 and R3 are not H; or (3) two of R1, R2 and R3, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole; and the other is selected from H, halogen and C2-C4 alkynyl. Also provided are reductive prodrugs, comprising a kinase inhibitor as defined above and a reductive trigger linked directly or indirectly to a nitrogen of the kinase inhibitor. Further provided are pharmaceutical compositions, comprising the kinase inhibitors or the prodrugs, and the use of such compositions in therapy, in particular for treating cancer.
