Abstract:
This invention relates to peptidomimetic linkers and anti-body drug conjugates thereof, to pharmaceutical compositions containing them, and to their use in therapy for the prevention or treatment of cancer.
Abstract:
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:
Abstract:
The present invention relates generally to nitro-1,2-dihydro-3H-benzo[e]indoles 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.
Abstract:
##STR1## Nitrobenzyl mustard quaternary salts of formula (I), and the pharmaceutically acceptable salts thereof, process for their manufacture and their chemotherapeutic use as hypoxia selective cytotoxic agents. Wherein, X represents a linker chain --CR 1 R 3 -- or CR 1 ═CR 2 -- (where R 1 and R 2 are separately H, lower alkyl, phenyl or nitrophenyl; Y is halogen or OSO 2 R; Q is lower alkyl (optionally substituted with alkyl and/or ether groups and containing up to 6 carbons) or nitrophenyl; Ar represents a mono- or bicyclic aromatic unit, R is lower alkyl optionally substituted with alkyl and/or ether groups, and may contain up to eight carbon atoms. Z represents one or more of the groups NO 2 , SO 2 R, CONHR, R, OR, SR, CF 3 and aza (ring --CH-- replared by --N═); with the proviso that when Y=Cl or Br, Q=Me, and X=--CH 2 -- then Ar≠2-nitrophanyl or 4-nitrophenyl.

Abstract:
The invention provides compounds of general formula (I), wherein: X is halogen or OSO.sub.2 R, where R represents H or is unsubstituted or hydroxy-or amino-substituted lower alkyl; Y is a nitro or amine group or a substituted derivative thereof; W is selected from the structures of formulae (Ia, Ib or Ic), where E is --N.dbd. or --CH.dbd., G is O, S, or NH, and Q is either up to three of R, OR, NRR, NO.sub.2, CONHR, NHCOR or NHCONHR, or is an additional group of formulae (Ia, Ib or Ic) and HET represents a 5- or 6-membered carbocycle or heterocycle; and A and B collectively represent a fused benzene or 2-CO.sub.2 R pyrrole ring. In one embodiment, the group Y is an amine derivative substituted by a group which is a substrate for a nitroreductase or carboxypeptidase enzyme such that one of said enzymes is able to bring about removal of that group. ##STR1##
