趋化因子受体CCR5是HIV-1病毒进入人体细胞的主要辅助受体,CCR5拮抗剂可作为一种靶向制剂,以防治人类HIV-1感染.目前,非肽类小分子化合物CCR5拮抗剂的研究占据主导地位.本文以5-溴水杨醛、4-氯苄氯为原料,通过消去、还原及溴化合成了4-溴-2-溴甲基-1-((4-氯苄基)氧)苯(中间体3),以1-苄基-4-哌啶酮合成了N-烯丙基-N-(4-哌啶基)苯甲酰胺,通过中间体3、中间体7合成了一种有望用作CCR5拮抗剂的新的非肽类小分子化合物N-烯丙基-N-(1-(5-溴-2-(对氯苄基氧基)苄基)-4-哌啶基)苯甲酰胺,该产物有一定的生物活性,并对该产物进行了1 H NMR、13C NMR、IR及MS表征.
In this paper,unsaturated double bond functional group was chemically inserted onto the surface of hydroxypatite particles by esterification reaction with methacrylic acid,then UV irradiation polymerization reaction of methacrylic acid onto the surface of hydroxypatite particles was taken place in situ.ESCA,FTIR,particle size analysis and SEM tests showed that the surfaces of hydroxypatite particles were successfully free-radical polymerized with methacrylic acid,the average particle size increased greatly as compared with that of pure hydroxypatite particles.
