苯呋洛尔性质、用途与生产工艺
(±)-Befunolol 是一种 β-肾上腺素能受体阻断剂。
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.
化学性质
结晶。熔点115℃。苯呋洛尔盐酸盐（C16H21NO4·HCI)，熔点163℃。
用途
该品属β-肾上腺素功能阻滞剂。可治疗青光眼。小鼠静脉注射LD50为100-105mg/kg。
生产方法
由2-乙酰-7-羟基苯并呋喃与3-氯-1,2-环氧丙烷反应后再与异丙胺作用而得。取8.8g2-乙酰-7-羟基苯并呋喃中，加入80ml3-氯-1,2-环氧丙烷和0.2g盐酸哌啶。将混合物加热至105℃，反应3h。反应后蒸发出过量的3-氯-1,2-环氧丙烷。生成物在减压下蒸馏，得9.3g2-乙酰-7-（2,3-环氧丙氧）苯并呋喃，沸点175-176℃（93Pa）。取6g上述生成物溶于30ml乙醇中，加10ml异丙胺，混合物回流40min，由反应混合物中蒸除溶剂，得到的残余物用环己烷-丙酮重结晶，得6g苯呋洛尔。
