Evenamide (NW-3509) is a blocker of voltage-gated sodium channels. Evenamide modulates sustained repetitive firing, without inducing impairment of normal neuronal excitability. It normalizes glutamate release induced by aberrant sodium channel activity. The potential benefits of the compound have been demonstrated in numerous preclinical models predictive of efficacy in psychiatric diseases, including models of psychosis such as amphetamine-induced hyperactivity, sensorimotor gating and information processing deficits (pre-pulse inhibition impairment induced by different stimuli), mania and depression. Evenamide is being evaluated in a Phase II trial as add-on treatment to 5HT2/D2 blocking antipsychotics in schizophrenic patients.

PH-797804 is a diarylpyridinone inhibitor of p38alpha mitogen-activated protein. The drug was developed by Pfizer for the treatment of inflammatory diseases. PH-797804 is being tested in phase II of clinical trials in patients with COPD, osteoarthritis, rheumatoid arthritis and post-herpetic neuralgia.

Anatibant was a selective small-molecule antagonist of the bradykinin B2 receptor that was undergoing clinical development with Xytis and Fournier for the treatment of brain injuries. Anatibant reduces brain oedema in animal TBI models. Noserious toxicity was found in Phase 1 clinical trials. Following subcutaneous administration of clinically relevant doses, there were no systemic effects but there was pain, inflammation and nodule formation at the injection site. Anatibant inhibits the binding of BK to the B2 receptor. After subcutaneous injection Anatibant is bio-available and crosses the BBB.

Resiquimod is an imidazoquinolinamine and Toll-like receptor (TLR) agonist with potential immune response modifying activity. Resiquimod exerts its effect through the TLR signaling pathway by binding to and activating TLR7 and 8 mainly on dendritic cells, macrophages, and B-lymphocytes. This induces the nuclear translocation of the transcription activator NF-kB as well as activation of other transcription factors. This may lead to an increase in mRNA levels and subsequent production of cytokines, especially interferon-alpha (INF-a) and other cytokines, thereby enhancing T-helper 1 (Th1) immune responses. In addition, topical application of resiquimod appears to activate Langerhans' cells, leading to an enhanced activation of T-lymphocytes. Resiquimod is used as a topical gel[1] in the treatment of skin lesions[2] such as those caused by the herpes simplex virus[3][4] and cutaneous T cell lymphoma. Due to its immunostimulatory activity, this agent may potentially be used as a vaccine adjuvant.
