Claimed are unsymmetrical Pyrrolobenzodiazepine-dimers (PBD-dimers) of formula (I), that are unsymmetrical due at least to the values that the variables R12 and R2 represent. Formula (I), wherein: R2 is of formula (II), where A is a C5-7 aryl group, X is selected from the group comprising: OH, SH, CO2H, COH, N=C=O, NHRN, wherein RN is selected from the group comprising H and C1-4 alkyl, and (OC2H4)mOCH3, where m is 1 to 3, and either: (i) Q1 is a single bond, and Q2 is selected from a single bond and -Z-(CH2)n-, where Z is selected from a single bond, O, S and NH and n is from 1 to 3; or (ii) Q1 is -CH=CH-, and Q2 is a single bond; R12 is a C5-10 aryl group, optionally substituted by one or more substituents selected from the group comprising: halo, nitro, cyano, ether, C1-7 alkyl, C3-7 heterocyclyl and bis-oxy-C1-3 alkylene. The other variables are as defined in the claims. The compounds are useful for the treatment of proliferative diseases.
所述为式(I)的不对称吡咯并苯并二氮杂卓二聚体(PBD-二聚体),其不对称性至少由于变量R12和R2所代表的值。式(I)中:R2为式(II),其中A为C5-7芳基,X选自包括OH、SH、CO2H、COH、N=C=O、NHRN的组,其中RN选自包括H和C1-4烷基的组,以及(OC2H4)mOCH3,其中m为1至3,且任选地:(i) Q1为单键,Q2选自单键和-Z-(CH2)n-,其中Z选自单键、O、S和NH,n为1至3;或(ii) Q1为-CH=CH-,Q2为单键;R12为C5-10芳基,任选地被一个或多个选自包括卤素、硝基、氰基、醚、C1-7烷基、C3-7杂环烷基和双氧-C1-3亚烷基的组的取代基取代。其他变量如权利要求中所定义。这些化合物可用于增殖性疾病的治疗。
