PK-11195 was first discovered by Pharmuka Laboratories. It was found to be antagonist of the Translocator Protein (TSPO) with potential for development in a number of conditions including cancer models, cardiac ischemia, seizures, depression, and anxiety. PK-11195 has been studied extensively in vitro and in animal models. In phase I clinical trials no anti-inchemic effects were found after drug administration. A tritium [3H] labeled and a C-11 labeled version of PK-11195 are both used diagnostically as PET imaging compounds.

Sample Use Guides
Mice received an intraperitoneal injection of PK-11195 (30 - 120 mg/kg ) 30 min before inducing convulsions with one of Ro 5-4864, Ro 5-
3663, PTZ or picrotoxin. Results were mixed. PK-11195 significantly reduced the incidence of convulsions caused by Ro 5-4864 but was ineffective at countering seizures brought on by Ro 5-3663 and picrotoxin. Furthermore, PK 11195 had pro-convulsant actions when combined with sub-convulsant doses of strychnine and picrotoxin.
Route of Administration:
Other
Human breast cancer cell lines MCF-7 and T47D were cultured and viability and proliferation were determined with a CCK-8 assay. A TSPO selective ligand AC-5216 was added to enhance cellular proliferation and production of allopregnanolone. PK-11195 blocked the effects of AC-5216 with IC50 values of 5.4 nM and 6 nM in MCF-7 and T47D cells respectively.
