Taltirelin (TA-0910, brand name Ceredist) is a synthetic, metabolically stable analog of thyrotropin-releasing hormone (TRH), the three-residue hypothalamic peptide. It was developed by Tanabe Seiyaku and approved in Japan in 2000 for spinocerebellar degeneration, where it is taken orally to help with ataxia and related symptoms. The interesting thing about taltirelin is that it was engineered to keep the central nervous system effects of TRH while shedding most of the hormonal ones; it is roughly 10 to 100 times more potent than native TRH at driving CNS arousal, yet its effect on thyroid hormone release is much weaker. It also lasts far longer in the body because it resists the enzymes that chew up natural TRH within minutes. Outside its approved use it gets discussed in nootropic and biohacker circles as a wakefulness-promoting, pro-cholinergic "analeptic" and neuroprotective agent, and there is a real preclinical literature behind those claims (Parkinson's models, ischemia, pain, respiratory stimulation). Human data outside spinocerebellar degeneration is thin, so most of what you read about it as a cognitive enhancer is extrapolation from animal work.
Adrogolide is a water-soluble prodrug that rapidly converts in plasma to A-86929, a highly selective full agonist at dopamine D1 receptors. It was investigated by Abbott Laboratories and DrugAbuse Sciences for Parkinson's disease and cocaine dependence but development was discontinued in 2001.
