A series of cis-1,2-dihydroxy-1,2-dihydrobenzo[b]acronycine diacid hemiesters and dicarbamates were prepared by acylation of cis-1,2-dihydroxy-6-methoxy-3,3,14-trimethyl-1,2,3,14-tetrahydro-7H-benzo[b]pyrano[3,2-h]acridin-7-one. The cytotoxicity of the dicarbamates depended on the steric hindrance of the esterifying groups at positions 1 and 2. Diacid hemiesters displayed significant in vitro cytotoxic activities and induced cell cycle perturbations similar to those obtained with cis-1,2-diacetoxy-1,2-dihydrobenzo[b]acronycine (S23906-1) currently under preclinical development. cis-1-Acetoxy-2-hemiglutaryloxy-1,2-dihydrobenzo[b]acronycine was the most promizing compound of the series, inducing complete inhibition of tumor growth when tested against C38 colon adenocarcinoma implanted in mice.
通过顺式-1,2-二羟基-6-甲氧基-3,3,14-三甲基-1的酰化制备了一系列顺式-1,2-二羟基-1,2-二氢苯并[b]醋栗碱二酸半酯和二氨基甲酸酯。 ,2,3,14-四氢-7H-苯并[b]吡喃并[3,2-h]吖啶-7-酮。二氨基甲酸酯的细胞毒性取决于位置 1 和 2 处酯化基团的空间位阻。二酸半酯表现出显着的体外细胞毒性活性,并诱导细胞周期扰动,类似于使用 cis-1,2-diacetoxy-1,2- 获得的结果。二氢苯并[b]acronycine (S23906-1)目前正处于临床前开发阶段。 cis-1-乙酰氧基-2-半戊二酰氧基-1,2-二氢苯并[b]acronycine是该系列中最有前途的化合物,当针对植入小鼠的C38结肠腺癌进行测试时,可完全抑制肿瘤生长。
