  Retinobenzoic Acids. 6. Retinoid Antagonists with a Heterocyclic Ring

  摘要：

  Several candidate retinoid antagonists were designed on the basis of the ligand superfamily concept and synthesized. Retinoidal activities of these benzimidazole and benzodiazepine derivatives were examined by assay of differentiation-inducing activity on human promyelocytic leukemia cell line HL-60. The parent benzimidazole derivative, 4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethylnapth[2,3-d]imidazol-2-yl)benzoic acid (7a), and related compounds with a small alkyl group instead of the hydrogen on the nitrogen (N-1) atom of the imidazole ring exhibited retinoidal activity, and the potency strongly depended on the bulkiness of the substituent. The compounds having a phenyl or benzyl group on the nitrogen lacked differentiation-inducing activity on HL-60 cells and acted as antagonists to the potent retinoid 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-napthalenyl)carbamoyl]benzoic acid (Am80). Among the compounds possessing a seven-membered heterocyclic ring as a linking group, 4-(5H-7,8,9,10-tetrahydro-5,7,7,10,10-pentamethylbenzo[e]naphtho[2,3-b][1,4]diazepin-13-yl)benzoic acid (16) also exhibited the antagonistic activity. The binding abilities of these compounds to retinoic acid receptors ct and P were consistent with their potency for the inhibition of HL-60 cell differentiation induced by the retinoid Am80.

  15-pentamethyldinaphtho[2,3-b][1,2-e]diazepin-7-yl) benzoic acid (LE540, 17), exhibits a 1 order of magnitude higher antagonistic potential than the parental LE135 (6). In contrast, 4-[5H-2,3-(2,5-dimethyl-2,5-hexano)-5-methyldibenzo[b,e] [1,4]diazepin-11-yl]-benzoic acid (HX600, 7), a structural isomer of the antagonistic LE135 (6), enhanced HL-60 cell differentiation induced by RAR agonists, such as Am80 (2)

  在人HL-60早幼粒细胞白血病细胞中，二氮杂pin基苯甲酸衍生物可以对天然或合成类维生素A的诱导分化活性表现出拮抗或协同作用，该活性很大程度上取决于二氮杂ring环上取代基的性质。因此，类视黄醇拮抗剂LE135（6），4-（13H-10,11,12,13-tetRAhydro-10，10,13,13,15-五甲基二萘并[2,3-b] [1,2 -e] diazepin-7-yl）苯甲酸（LE540，17）的拮抗潜力比亲代LE135（6）高1个数量级。相反，4- [5H-2,3-（2,5-二甲基-2,5-己基）-5-甲基二苯并[b，e] [1,4]二氮杂-11-基]-苯甲酸（HX600 ，LEAF（6）的结构异构体，（7）增强了RAR激动剂（例如Am80）诱导的HL-60细胞分化（2）。噻嗪类化合物HX630（29）和氮杂类衍生物HX640（30）的协同作用进一步增强。两者都比HX600（7
