体内（毎回新しく調製した物を用意してください）

Clear solution	5% DMSO 1 95% Corn oil	0.35mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 7 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	3.85mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 77 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Loratadine is a histamine H1 receptor antagonist, used to treat allergies. Also acts as a selective inhibitor of B(0)AT2 with IC50 of 4 μM.
in vitro	Loratadine is identified as a selective inhibitor of B(0)AT2 with an IC50 of 4 μM while being less active or inactive against several other members of the SLC6 family. ^[1] Loratadine concentration-dependently inhibits the release of histamine and LTC4 when preincubating before Der p 1 antigen or anti-Fc epsilon RI challenge in human Fc epsilon RI+ cells. Loratadine (0.1 mM) also inhibits (10-40%) histamine, LTC4, and PGD2 release from purified HLMC (16-68%) activated by anti-Fc epsilon RI. Loratadine causes concentration-dependent inhibition (10-40%) of histamine, tryptase, LTC4, and PGD2 release from purified HSMC (24-72%) immunologically challenged with anti-Fc epsilon RI. ^[2] Loratadine inhibits significantly IL-6 and IL-8 secretion induced by histamine with a more powerful efficiency of the active metabolite in human umbilical vein endothelial cells (HUVEC). ^[3] Loratadine blocks hKv1.5 channels in a concentration-, voltage-, time- and use-dependent manner but only at concentrations much higher than therapeutic plasma levels in man in Ltk- cells transfected with the gene encoding hKv1.5 channels. ^[4] Loratadine inhibits rhinovirus-induced ICAM-1 upregulation in both primary bronchial or transformed (A549) respiratory epithelial cells. Loratadine also inhibits ICAM-1 mRNA induction caused by rhinovirus infection in a dose-dependent manner, and they completely inhibits rhinovirus-induced ICAM-1 promoter activation. ^[5]
