Physical and Chemical Properties | White or off-white crystalline powder. Melting point 140-145 °c. Soluble in water, ethanol, insoluble in chloroform, ether. The melting point of the L-free base is 169-172 °c. |
Use | Adrenaline-like drugs. It has a contractile effect on local body blood vessels. It is used for surgical surgery to prolong the anesthesia time of local treatment and reduce swelling and inflammation of nasal mucosal congestion. |
In vitro study | Phenylephrine caused a rapid translocation of PKC-epsilon(EC 50=0.9mm), but the proportion of loss from the soluble fraction was less than ET-1. Phenylephrine caused a dose-dependent increase in the contractile force of hyperpermeable cells at pCa 7, which was reversible upon addition of phentolamine. Phenylephrine also protects cardiomyocytes from hypoxia and serum-deprivation treatment. Phenylephrine prevents down-regulation of Bcl-2 and Bcl-X mRNA/proteins and induction of hypertrophic growth. Phenylephrine-mediated protection is inhibited by the phosphatidylinositol 3-kinase (PI 3-kinase) inhibitor wortmannin and is mimicked by the caspase-9 peptide inhibitor LEHD-FMK. Phenylephrine stimulates phosphoinositide (PI) hydrolysis, cell growth, and expression of several genes associated with cardiac hypertrophy [e. G., atrial natriuretic factor (ANF)]. Phenylephrine(1 μm) significantly enhanced HGF-induced hepatocyte DNA synthesis and cell proliferation. Phenylephrine(1 mM) reversibly increased I(Ca,L)(51.3%; N = 40) and the peak I(Ca,L) of the activation voltage at -10 mV. Phenylephrine also increases the release of sarcolemmal SR calcium ions via ip3-dependent signaling. Phenylephrin induces the release of NOi, requiring stimulation by PI-3K/Akt and ip3-dependent calcium ion signals. Phenylephrine induces the release of NOi as 1 mM prazocin, 10 mM L-NIO, 10 mM W-7, 10 mM LY294002, 2 mM H-89, 10 mM ryanodine, 5 mM thapsigargin, 2 mM 2-APB or 10 mM xestospongin C inhibition. |

Content determination
take 5ml of this product accurately, put it in an iodine bottle, add lml of dilute hydrochloric acid, carefully boil it to near dryness, let it cool, add 20ml of water, and add 0.05mol/L of bromine titration solution accurately. 25ml, and then 2ml hydrochloric acid, immediately tamponade, shake, place for 15 minutes and always shake, pay attention to micro-open the stopper, add potassium iodide solution 7ml, immediately tamponade, shake after, with sodium thiosulfate titration solution (0.1 mol/L) titration, to the near end point, add starch indicator solution, continue titration to blue disappeared, and the titration result is corrected by blank test. Each 1 ml of bromine titrant (0.05mol/L) corresponds to 3.395mg of C9H13N02. HCI.
