Bioactivity

• Target IC50:
  B(0)AT2:4 μM
• In Vivo:
  Loratadine blocks Kv1.5 channels in a concentration-, voltage-, time-, and use-dependent manner when expressed in human Ltk-cells transfected with the hKv1.5 channel gene at concentrations exceeding therapeutic plasma levels. It also inhibits rhinovirus-induced upregulation of ICAM-1 in main bronchial or transformed respiratory epithelial cells. Identified as a selective inhibitor of B(0)AT 2 with an IC50 of 4 μM, loratadine exhibits low or no activity against several other members of the SLC6 family. Pre-incubation with loratadine concentration-dependently suppresses the release of histamine and LTC4 in human FcεRI+ cells upon challenge with Der p1 antigen or anti-FcεRI. In human umbilical vein endothelial cells, loratadine significantly inhibits histamine-induced secretion of IL-6 and IL-8, with its active metabolites showing even stronger effects. Additionally, loratadine in a dose-dependent manner inhibits the mRNA of ICAM-1 induced by rhinovirus infection and completely suppresses the activation of the rhinovirus-induced ICAM-1 promoter.
