Current Status
Currently nicotine receptor agonist research and drug designing is aimed for treatment of multiple diseases and disorders of the CNS.
Targacept has four drug candidates that are in clinical trials; AZD3480 (TC-1734) for ADHD which is currently in phase II clinical trials and AZD1446 (TC-6683) for Alzheimers disease in collaboration with AstraZeneca, TC-5619 for cognitive dysfunctions in schizophrenia and TC-5214 as an augmentation treatment for major depressive disorder (MDD) in subjects who did not respond adequately to first-line treatment with citalopram hydrobromide.
Memory pharmaceuticals with its partner Roche has one drug candidate, MEM 3454 (RG3487), a partial agonist of the nicotinic alpha-7 receptor, for Alzheimers disease.
Abbott Laboratories in partnership with NeuroSearch have two drug candidates in clinical trials, ABT-894, a selective α4β2 nicotine receptor agonist, for ADHD and ABT-560, a neuronal nicotinic receptor modulator, which was selected by Abbott in 2006 as a new development candidate for cognitive dysfunctions.
EnVivo pharmaceuticals has one drug candidate in clinical trials, EVP-6124, a selective α7 nicotine receptor agonist for Alzheimer’s disease and schizophrenia and one follow-up compound, EVP-4473, that has successfully completed pre-clinical development.

“The work of the political activist inevitably involves a certain tension between the requirement that positions be taken on current issues as they arise and the desire that one’s contributions will somehow survive the ravages of time.”
—Angela Davis (b. 1944)
“The influx of women into paid work and her increased power raise a woman’s aspirations and hopes for equal treatment at home. Her lower wage and status at work and the threat of divorce reduce what she presses for and actually expects.”
