Effects of solifenacin and mirabegron on vesical and urethral function were compared in rats with or without spinal cord injury. Isovolumetric cystometry and urethral pressure recording were initially performed in intact rats. Then, bladder neck was ligated under urethane anesthesia, after which catheter was inserted through bladder dome for isovolumetric cystometry and another catheter was inserted into urethra to measure urethral pressure. Solifenacin or mirabegron was injected i.v., and bladder and urethral activity were recorded. To create rats with SCI, the spinal cord was transected at lower thoracic level under isoflurane anesthesia. After 2 wk, catheter was inserted through bladder dome for single cystometry and bladder activity was recorded without anesthesia following i.v. injection of solifenacin or mirabegron. In SCI rats, single cystometry showed that solifenacin and mirabegron both increased bladder volume at first non-voiding bladder contraction and decreased the maximum bladder contraction pressure. Mirabegron also increased voided volume and decreased the percentage residual volume without altering bladder capacity. Solifenacin and mirabegron both inhibited bladder contractility, and mirabegron possibly also induced urethral relaxation. Mirabegron may be suitable for patients with overactive bladder and residual urine. In the experiment, the researchers used many compounds, for example, (S)-(R)-Quinuclidin-3-yl 1-phenyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (cas: 242478-37-1Category: isoquinoline).
(S)-(R)-Quinuclidin-3-yl 1-phenyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (cas: 242478-37-1) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. The discovery of chloroquine, the most well-known drug containing this stent, has helped bring about decades of malaria control and treatment.Category: isoquinoline
