While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 5390-04-5, Name is 4-Pentyn-1-ol. In a pantent, once mentioned the new application about 5390-04-5, Application of 5390-04-5.
We investigated the effects of the new muscarinic receptor antagonist solifenacin succinate [YM905; (+)(IS,3′ R)-quinuclidin-3′ -yl 1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate monosuccinate] and the current antimuscarinic drugs for the treatment of overactive bladder (oxybutynin, tolterodine and darifenacin) on intracellular Ca2+ mobilization in response to M-3 muscarinic receptor activation in bladder smooth muscle and submandibular gland cells isolated from Cynomolgus monkeys. Solifenacin concentration-dependently inhibited carbachol-induced Ca2+ mobilization, with affinity constant values (pKi) of 8.5+/-0.053 in bladder smooth muscle cells and 8.2+/-0.051 in submandibular gland cells (n=5). The pKi value of solifenacin was almost equivalent to the values of oxybutynin, tolterodine and darifenacin in bladder smooth muscle cells (8.7, 8.5 and 8.4, respectively), while being lower than those in submandibular gland cells (9.0, 8.7 and 8.8, respectively). The bladder-selectivity index (Ki ratio: submandibular gland/bladder) for solifenacin (2.1) was statistically higher, moreover, than those for oxybutynin, tolterodine and darifenacin (0.51, 0.65 and 0.46, respectively). These findings consequently indicate solifenacin’s unique profile in terms of its selectivity for bladder smooth muscle cells over salivary gland cells in non-human primates, relative to oxybutynin, tolterodine and darifenacin. Solifenacin may, therefore, confer a promising therapeutic advantage for reducing adverse effects, such as dry mouth, exhibited by current antimuscarinic therapy for overactive bladder.

Application of 5390-04-5, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 5390-04-5 is helpful to your research.
