Thioperamide (maleate) BiologicalActivity
| Description | Thioperamide maleate (MR-12842 maleate) is a potent, orally available, brain penetrant and selective H3 receptor antagonist with a Ki of 4.3 nM for inhibition of [3H]histamine release. Thioperamide maleate inhibits [3H]histamine synthesis with a Ki of 31 nM[1]. |

| In Vitro | Thioperamide inhibits [3H]-(R)α-MeHA binding rat brain and guinea-pig lung with Kis of 2.1 nM and 2.0 nM, respectively. Thioperamide competitively blocks H3-autoreceptors regulating [3H]histamine release with a mean apparent Ki of 4 nM[1]. Thioperamide (0.01-100 μM; 24 hours) promotes the viability of NE-4C stem cells in a concentration-dependent manner[2]. Thioperamide displays similar potencies at human H4 and H3 receptors (Ki=43 and 60 nM, respectively)[3]. Cell Viability Assay[2] Cell Line: NE-4C stem cells Concentration: 0.01, 0.1, 1, 10, 100 μM Incubation Time: 24 hours Result: The viability of NE-4C stem cells increased significantly to 150.83±6.91% when (1 μM) was administrated, and increased to 145.11±14.52% and 132.02%±25.65% when 10 μM and 100 μM were administrated respectively. |
| In Vivo | Thioperamide (5-20 mg/kg; i.p.) is able to facilitate reconsolidation of a contextually-conditioned fear memory in C57BL/6J mice[4]. Animal Model: Naive female C57BL/6J mice[4] Dosage: 5, 10 or 20 mg/kg Administration: Injections (i.p.) Result: Facilitated reconsolidation of a contextually-conditioned fear memory. |
