OUP-186 is a high affinity and human rat species-selective antagonist of histamine H3receptor. OUP-186 suppressed the proliferation of breast cancer cells. The IC50 values at 48 hours for OUP-186 was approximately 50 μM. OUP-186 potently induced cell dea
Cipralisant is a selective histamine H3receptor antagonist in vivo, and an agonist in vitro (pKi: 9.9 for histamine H3receptor; Ki: 0.47 nM for rat histamine H3receptor). It has the potential for the treatment of attention-deficit hyperactivity disorde
A-940894 is a histamine H4 receptor antagonist with anti-inflammatory properties. A-940894 potently binds to both human and rat histamine H4 receptors and exhibits considerably lower affinity for the human histamine H1, H2, or H3receptors. A-940894 has g
ROS 234 is a highly effective H3 antagonist, demonstrating a strong binding affinity (pK B) of 9.46 for the Guinea-pig ileum H3receptor and a pKi of 8.90 for the Rat cerebral cortex H3receptor. Additionally, it exhibits an ex vivo ED50 of 19.12 mg kg (ip) in the Rat cerebral cortex. It should be noted that ROS 234 demonstrates limited central access, as reported in [1] and [2].
