A C2/C2â²-exo unsaturated pyrrolobenzodiazepine dimer 1 has been synthesised which is cytotoxic at the picomolar level and has remarkable covalent DNA binding affinity, raising the melting temperature of duplex-form calf thymus DNA by 34 °C after 18 h incubation.
合成了C2/C2'的非饱和吡咯并苯二氮杂卓二聚体1,其在皮摩尔级别具有细胞毒性,并对双链牛胸腺DNA有显著的共价结合亲和力,经过18小时孵育后使DNA的熔解温度升高了34摄氏度。
