More Details of Protagenic Therapeutics Inc Company

Protagenic Therapeutics, Inc. is a biopharmaceutical company specializing in the discovery and development of therapeutics to treat stress-related neuropsychiatric and mood disorders. Its lead compound, PT00114, is a synthetic form of Teneurin Carboxy-terminal Associated Peptide (TCAP), an endogenous brain signaling peptide that can dampen overactive stress responses. Its lead compound is a 41-amino-acid synthetic peptide, which focuses on treating various neuro-psychiatric conditions, including depression, anxiety, and post-traumatic stress disorder (PTSD). It operates with a novel mechanism, mirroring the active part of the natural brain hormone TCAP, thereby reducing circulating cortisol levels. In addition, it has a portfolio of earlier stage neuropeptides targeting the TCAP pathway that are in preclinical evaluation. The initial dosage form is intended as a subcutaneous injection but is also amenable to other routes of administration including sublingually or intra-nasally.
