In a continuing program to discover antipsychotic agents with a reduced propensity toward extrapyramidal side-effects, a series of N-alkoxyimides and -amides was prepared. Evaluation of these compounds in vitro revealed affinities for D2, 5HT2 and 5HT1A receptors. Several members of the series displayed a profile indicative of potential antipsychotic activity in preclinical assays. The most potent compound in these assays, 7, also displayed possible effectiveness for the negative symptoms of schizophrenia. The synthesis of these compounds and details of their structure-activity relationships are described.

D011942 Receptors, Adrenergic, alpha One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation.

D002375 Catalepsy A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.
