Alzheimer's disease (AD) is a neurodegenerative disorder associated with a decline in memory deficits and neuropathological diagnosis with loss of cholinergic neurons in the brains of older adults. Based on these facts and an increasing number of involved people worldwide, this investigation aimed to study the improvement of memory and cognitive impairments via an anticholinergic approach of thiazolidine-2,4-diones (TZDs) in the scopolamine-induced model of Alzheimer type in adult male Wistar rats (n = 40). The results indicated data analysis obtained from in vivo and in vitro tests for (E)-5-(3-hydroxybenzylidene)-3-(2-oxo-2-phenylethyl)thiazolidine-2,4-dione (TZ3O) (2 and 4 mg/kg) with the meta-hydroxy group and (E)-5-(4-methoxybenzylidene)-3-(2-oxo-2-phenylethyl)thiazolidine-2,4-dione (TZ4M) (2 and 3 mg/kg) with the para-methoxy group showed a neuroprotective effect. TZ3O and TZ4M alleviated the scopolamine-induced cognitive decline of the Alzheimer model in adult male Wistar rats. These initial and noteworthy results could be assumed as a starting point for the evolution of new anti-Alzheimer agents.
