The invention relates to certain pyrrolobenzodiazepines (PBDs), and in particular pyrrolobenzodiazepine dimers bearing C2 substitutions, including compounds of formula (T): wherein: R2 is CHR2A, and R2A is independently selected from H, R, CO2R, COR, CHO, CO2H, and halo; R6 and R9 are independently selected from H, R, OH, OR, SH, SR, NH2, NHR, NRR', NO2, Me3Sn and halo; R7 is independently selected from H, R, OH, OR, SH, SR, NH2, NHR, NRR', NO2, Me3Sn and halo; R8 is independently selected from H, R, OH, OR, SH, SR, NH2, NHR, NRR', NO2, Me3Sn and halo; R is independently selected from optionally substituted C1-12 alkyl, C3-20 heterocyclyl and C5-20 aryl groups; or the compound is a dimer with each monomer being of formula (M), where the R7 groups or R8 groups of each monomer form together a dimer bridge having the formula -X-R"-X- linking the monomers; wherein R" is a C3-I2 alkylene group, which chain may be interrupted by one or more heteroatoms, e.g. O, S, N(H), and/or aromatic rings, e.g. benzene or pyridine; and each X is independently selected from O, S, or N(H); or any pair of adjacent groups from R6 to R9 together form a group -O-(CH2)P-O-, where p is 1 or 2, and salts and solvates thereof, and their use as intermediates for the preparation of other PBD compounds.
该发明涉及某些吡咯苯并二氮杂环己烷(PBDs),特别是带有C2取代基的吡咯苯并二氮杂环己烷二聚体,包括以下式(T)的化合物:其中:R2为CHR2A,R2A独立选择自H、R、CO2R、COR、CHO、CO2H和卤素;R6和R9独立选择自H、R、OH、OR、SH、SR、NH2、NHR、NRR'、NO2、Me3Sn和卤素;R7独立选择自H、R、OH、OR、SH、SR、NH2、NHR、NRR'、NO2、Me3Sn和卤素;R8独立选择自H、R、OH、OR、SH、SR、NH2、NHR、NRR'、NO2、Me3Sn和卤素;R独立选择自可选择取代的C1-12烷基、C3-20杂环烷基和C5-20芳基;或该化合物是每个单体为式(M)的二聚体,其中每个单体的R7基团或R8基团共同形成具有-X-R"-X-连接单体的二聚体桥,其中R"为C3-I2烷基,该链可以被一个或多个杂原子中断,例如O、S、N(H)和/或芳香环,例如苯或吡啶;每个X独立选择自O、S或N(H);或从R6到R9的任意相邻基团对共同形成一个基团-O-(CH2)P-O-,其中p为1或2,以及其盐和溶剂化合物,以及它们作为制备其他PBD化合物的中间体的用途。
