Abstract: The invention relates to pyrrolo[2,1-c][1,4]benzodiazepines (PBDs) of formula (I) and in particular to PBD dimers linked through the C1 position, and PBD monomers linked through the C1 position to aromatic groups, and pharmaceutically acceptable salts thereof, which are useful as medicaments, in particular as anti-proliferative agents.

Abstract: Novel pyrrolobenzodiazepines (PBDs) having a (1-methyl-1H-pyrrol-3-yl)phenyl based amino acid residue and use thereof as antiproliferative agents are disclosed herein.

Abstract: A compound of formula (I) or a salt or solvate thereof, wherein the dotted double bond indicates the presence of a single or double bond between C2 and C3; R2 is selected from —H, —OH, ?O, ?CH2, —CN, —R, OR, halo, dihalo, ?CHR, ?CHRR?, —O—SO2—R, CO2R and COR; R7 is selected from H, R, OH, OR, SH, SR, NH2, NHR, NRR?, nitro, Me3Sn and halo; where R and R? are independently selected from optionally substituted C1-7 alkyl, C3-20 heterocyclyl and C5-20 aryl groups; R10 and R11 either together form a double bond, or are selected from H and QRQ respectively, where Q is selected from O, S and NH and RQ is H or C1-7 alkyl or H and SOxM, where x is 2 or 3, and M is a monovalent pharmaceutically acceptable cation; A is selected from (A1), (A2), (A3), (A4) or (A5) where X1 and Y1 are selected from: CH and NH; CH and NMe; N and NMe; CH and S; N and S; N and O; and CH and O, respectively; X2 and Y2 are selected from: CH and NH; CH and NMe; N and NMe; CH and S; N and S; N and O; and CH and O, respectively; Z1 is selected fr

Abstract: Pyrrolobenzodiazepine (PBDs) having a (1-methyl-1H-pyrrol-3-yl)phenyl based amino residue were found to be highly effective compounds having improved cytotoxicity ad DNA binding properties.
