Claimed are unsymmetrical Pyrrolobenzodiazepine-dimers (PBD-dimers) of formula (I), that are unsymmetrical due at least to the values that the variables R
12
and R
2
represent. Formula (I), wherein: R
2
is of formula (II), where A is a C
5-7
aryl group, X is selected from the group comprising: OH, SH, CO
2
H, COH, N═C═O, NHR
N
, wherein R
N
is selected from the group comprising H and C
1-4
alkyl, and (OC
2
H
4
)
m
OCH
3
, where m is 1 to 3, and either: (i) Q
1
is a single bond, and Q
2
is selected from a single bond and —Z—(CH
2
)
m
—, where Z is selected from a single bond, O, S and NH and n is from 1 to 3; or (ii) Q
1
is —CH═CH—, and Q
2
is a single bond; R
12
is a C
5-10
aryl group, optionally substituted by one or more substituents selected from the group comprising: halo, nitro, cyano, ether, C
1-7
alkyl, C
3-7
heterocyclyl and bis-oxy-C
1-3
alkylene. The other variables are as defined in the claims. The compounds are useful for the treatment of proliferative diseases.
所述的是公式(I)的非对称吡咯并苯并二氮杂环双聚物(PBD-二聚体),其非对称性至少由变量R12和R2所代表的值决定。公式(I)中:R2为公式(II)的结构,其中A为C5-7芳基基团,X选自包括:OH、SH、CO2H、COH、N═C═O、NHRN的群,其中RN选自包括H和C1-4烷基的群,以及(OC2H4)mOCH3,其中m为1至3,并且要么:(i)Q1为单键,Q2选自单键和—Z—(CH2)m—,其中Z选自单键、O、S和NH,n为1至3;要么(ii)Q1为—CH═CH—,Q2为单键;R12为C5-10芳基基团,可选择地被一个或多个取代基所取代,所述取代基选自卤、硝基、氰基、醚、C1-7烷基、C3-7杂环基和双氧-C1-3烷基。其他变量如权利要求所定义。所述化合物用于治疗增殖性疾病。
