代谢
在动物中,盐酸哌唑嗪被大量代谢。这是通过肝脏的去甲基化和结合作用发生的。在体外的人类或人类细胞研究中,也显示了类似的哌唑嗪代谢过程。
In animals, prazosin hydrochloride is heavily metabolized. This occurs through liver demethylation and conjugation. Some studies in humans or human cells in vitro show similar prazosin metabolism.

毒理性
  • 肝毒性
普拉唑辛与血清转氨酶升高率低有关,在对照试验中,其升高率并不高于安慰剂治疗。这些升高是短暂的,不需要调整剂量。文献中没有发表过由于普拉唑辛导致的临床上明显的急性肝损伤的案例,但是赞助商收到了胆汁淤积性肝炎的报告。在α肾上腺素能受体拮抗剂中,最常导致肝损伤的药物是阿夫唑辛,而与其他α阻滞剂相关的案例只有单一的,并且记录不完整。因此,普拉唑辛导致的急性症状性肝损伤非常罕见,如果发生,严重肝毒性也极为罕见。
Prazosin has been associated with a low rate of serum aminotransferase elevations that in controlled trials was no higher than with placebo therapy. These elevations were transient and did not require dose modification. No instances of clinically apparent acute liver injury due to prazosin have been published in the literature, but reports of cholestatic hepatitis have been received by the sponsor. Among the alpha adrenergic receptor antagonists, the most frequently implicated agent in causing liver injury has been alfuzosin with only single, and not well documented cases linked to other alpha blockers. Thus, acute symptomatic liver injury due to prazosin is quite rare, and severe hepatotoxicity must be exceeding rare, if it occurs at all.

口服给药后,血浆浓度在大约3小时达到峰值。普拉唑辛剂量与稳态时血浆浓度之间存在线性关系。

制备方法与用途

产品特点

哌唑嗪(Prazosin hydrochloride)是由美国辉瑞公司推出的一种全新的扩血管降压药。与传统的血管扩张药物不同,它不仅具有扩张血管和降低血压的作用,还避免了反射性地兴奋交感神经而加快心率的情况,并且能够抑制肾素释放甚至降低血浆肾素活性。临床研究表明,哌唑嗪对不同等级的高血压、心力衰竭等疾病均有良好的疗效。

副作用

首次服用哌唑嗪时,可能会出现严重的体位性低血压、眩晕、头痛、心悸和出汗等症状。此外,对中枢神经系统的影响可能包括紧张、头晕、晕厥、精神不振、抑郁、感觉异常和视力模糊等。因此,在首次服药或调整剂量后的第一天,请避免驾车或从事危险工作。

生物活性

Prazosin是一种α1阻断剂,是alpha-1肾上腺素能受体的反向激动剂。

靶点
Target Value
α1-adrenergic receptor ()
化学性质

哌唑嗪为结晶状固体,熔点278-280℃。其盐酸盐([19237-84-4])为白色结晶性粉末,熔点在275℃时开始分解。它难溶于乙醇,略溶于等渗盐水和水中,并具有无臭、味苦的特点。

用途

哌唑嗪选择性地阻滞突触后膜上的α受体,直接松弛血管平滑肌,扩张小动脉和小静脉,减轻心脏前负荷和后负荷。作为一种较新的血管扩张药,在临床上广泛用于治疗高血压和心力衰竭等疾病。

生产方法
  1. 3,4-二甲氧基-6-氨基苯腈在水和二氯甲烷中与硫肛光气反应得到3,4-二甲氧基-6-异硫氰酰苯腈(收率94%)。
  2. 将其与1-(2-呋喃甲酰)哌嗪在乙酸乙酯中进行反应,制得硫脲衍生物(收率90%)。
  3. 再通过甲基化反应,并用碱处理得到游离S-甲基异硫脲衍生物(收率95%)。
  4. 最后,在甲酰胺介质中与氨、氯化铵和尿素反应制得哌唑嗪。

    Synthetic approaches, functionalization and therapeutic potential of quinazoline and quinazolinone skeletons: The advances continue
    摘要:
    The presence of N-heterocycles as an essential structural motif in a variety of biologically active substances has stimulated the development of new strategies and technologies for their synthesis. Among the various N-heterocyclic scaffolds, quinazolines and quinazolinones form a privileged class of compounds with their diverse spectrum of therapeutic potential. The easy generation of complex molecular diversity through broadly applicable, cost-effective, practical and sustainable synthetic methods in a straightforward fashion along with the importance of these motifs in medicinal chemistry, received significant attention from researchers engaged in drug design and heterocyclic methodology development. In this perspective, the current review article is an effort to recapitulate recent developments in the eco-friendly and green procedures for the construction of highly challenging and potentially bioactive quinazoline and quinazolinone compounds in order to help medicinal chemists in designing and synthesizing novel and potent compounds for the treatment of different disorders. The key mechanistic insights for the synthesis of these heterocycles along with potential applications and manipulations of the products have also been conferred. This article also aims to highlight the promising future directions for the easy access to these frameworks in addition to the identification of more potent and specific products for numerous biological targets.
