制備方法
方法1
由2-乙酰-7-羥基苯并呋喃與3-氯-1,2-環(huán)氧丙烷反應后再與異丙胺作用而得。取8.8g2-乙酰-7-羥基苯并呋喃中,加入80ml3-氯-1,2-環(huán)氧丙烷和0.2g鹽酸哌啶。將混合物加熱至105℃,反應3h。反應后蒸發(fā)出過量的3-氯-1,2-環(huán)氧丙烷。生成物在減壓下蒸餾,得9.3g2-乙酰-7-(2,3-環(huán)氧丙氧)苯并呋喃,沸點175-176℃(93Pa)。取6g上述生成物溶于30ml乙醇中,加10ml異丙胺,混合物回流40min,由反應混合物中蒸除溶劑,得到的殘余物用環(huán)己烷-丙酮重結(jié)晶,得6g苯呋洛爾。常見問題列表
生物活性
(±)-Befunolol 是一種 β-腎上腺素能受體阻斷劑。靶點
Adrenoreceptor
體外研究
A β-adrenoceptor blocking agent, Befunolol, is found to has intrinsic sympathomimetic activities in isolated right atria, trachea and taenia caecum of guinea pig (intrinsic activities are 0.22-0.28). The pD2-values of Befunolol estimated in the isolated organs are significantly different from its pA2-values against isoprenaline. Befunolol interacts with the beta-adrenoceptor where there may be two different sites: one site for agonistic action and the other for competitive antagonistic action. The intrinsic activity of Befunolol may be equal to its selectivity for both the sites.
