A-77636 is a synthetic drug which acts as a selective D1 receptor full agonist.[2] It has nootropic, anorectic, rewarding and antiparkinsonian effects in animal studies,[3][4][5][6][7] but its high potency and long duration of action causes D1 receptor downregulation and tachyphylaxis,[8][9][10] and unlike other D1 full agonists such as SKF-82,958, it does not produce place preference in animals.[11] A-77636 partially substituted for cocaine in animal studies, and has been suggested for use as a possible substitute drug in treating addiction,[12] but it is better known for its use in studying the role of D1 receptors in the brain.[13][14][15]
