摘要:

目的:探讨新型聚腺苷二磷酸核糖多聚酶(PARP-1)抑制剂合成过程中溶剂、缚酸剂、反应温度、时间及乙酸乙酯用量等因素对产物收率的影响,从而优化合成工艺。方法:以2-氟-5-[(4-氧代-34-二氢二氮杂萘-1-基)甲基]苯甲酸为起始原料,通过酰氯化反应生成中间产物2-氟-5-[(4-氧代-34-二氢酞嗪-1-基)甲基]苯甲酰氯,随后与胺类化合物进行酰胺化反应,生成目标产物。结果:酰氯化反应在氯化亚砜作为溶剂、原料与氯化亚砜摩尔比113.4、反应温度6070 ℃、反应时间3 h的条件下,表现出最佳效果;而酰胺化反应中,采用吡啶与三乙胺的混合缚酸剂[n(吡啶)∶n(三乙胺)=0.15],且当缚酸剂与芳香胺的摩尔比达到2.5、反应温度-5 ℃、反应时间6.56.8 h,并使用6倍量的乙酸乙酯进行提纯时,产物收率可达到最高值86.2%。结论:本研究成功合成了15个新型奥拉帕尼衍生物,为开发高效低毒的新型药物提供了更多可能性。

Abstract:

Objective: To investigate the influence of solvent acid binding agent reaction temperature time and amount of ethyl acetate during the synthesis process on the yield of PARP-1 inhibitorsso as to optimize the synthesis process.Methods: Using 2-fluoro-5 -[(4-oxo-34-dihydrodiazanaphthalene -1-yl methyl benzoic acid as the starting material the intermediate product 2-fluoro-5-[(4-oxo-34-dihydrophthalazine-1-yl methyl benzoyl chloride was formed by acyl chlorination reaction and then amidation reaction with amine compounds was carried out to produce the target product.Results: The results showed that the best results were obtained under the conditions of sulfoxide chloride as solvent molar ratio of raw meterial to sulfoxide chloride 113.4reaction temperature 60-70 ℃ and reaction time 3 h. In the amidation reaction the mixed acid binding agent of pyridine and triethylamine npyridine)∶ntriethylamine=0.15 was used and when the molar ratio of acid binding agent and aromatic amine reached 2.5 the reaction temperature was -5 ℃the reaction time 6.5-6.8 h and when 6 times the amount of ethyl acetate was used for purification the yield of product could reach the highest value of 86.2%.Conclusion: This study successfully synthesized 15 novel derivatives of Olaparib providing more possibilities for the development of highly efficient and low-toxicity new drugs.
