| 生物活性 | 27-Hydroxycholesterol is a selective estrogen receptor modulator and an agonist of the liver X receptor.[1-4] |
| In Vitro | 27-Hydroxycholesterol is an endogenous selective estrogen receptor modulator that displays significant partial agonist activity in a variety of cellular models of estrogen receptor action. It positively regulates both gene transcription and cell proliferation in cellular models of breast cancer[1]. 27-Hydroxycholesterol,through estrogen receptor activation,triggers deleterious effect in prostate cancer cell lines. 27-Hydroxycholesterol significantly increases cell proliferation of LNCaP and PC3 cells and this effect can be attenuated by estrogen receptor inhibitors[2]. 27-Hydroxycholesterol is an oxysterol produced from cholesterol by the monooxygenase CYP27A1,which regulates intracellular cholesterol homeostasis. 27-Hydroxycholesterol also acts as an endogenous selective estrogen receptor modulator capable of increasing breast cancer growth and metastasis. 27-Hydroxycholesterol levels can be modulated by statins or direct inhibition of CYP27A1,thereby attenuating its pro-tumorigenic activities[3]. 27-hydroxylation of cholesterol is an important pathway for LXR activation in response to cholesterol overload[4]. |

文献和实验19例。 1.2标本采集均为空腹12h以上静脉血,采集后分离血清,-70℃保存。 1.3血脂测定采用东鸥生化试剂厂酶法单一试剂及标准物,以ARCO-PC生化分析仪,测定血清总胆固醇(TC),甘油三酯(TG),高密度脂蛋白胆固醇(HDL-C)及低密度脂蛋白胆固醇(LDL-C)。 1.4统计学方法测定结果均以ˉx±s表示,组间数据比较采用方差分析。 2结果 妊娠妇女血脂变化情况详见表1.表中显示,随着怀孕周期的增加,血脂四项测定含量逐渐增加,血清TC、TG

反应。几乎所有可用于偶联反应的活泼酯都可用于合成环肽,主要有对硝基酚酯、N-羟基琥珀酰亚胺酯、五氟苯酯和2,4,5-三氯苯酚酯。线性多肽的C端羧基与对硝基酚、N-羟基琥珀酰亚胺、五氟苯酚或2,4,5-三氯苯酚,在DCC或其他缩合剂存在下,于低温反应,很容易得到相应的活泼酯。这种N端通常带有BOC或Z保护的活泼酯在酸性条件下脱去保护基,形成活泼酯的氢卤酸盐,在弱碱性稀溶液中,如在吡啶,DMF或二氧六环一类介电常数较大的溶剂中,保持pH8~9,加热(60~100℃)或室温搅拌数小时至数日,最终可得到环肽
