Neuropharmacological studies with the compound 2-methyl, 3-phenyl, 3-methyltransxydroxasino-propiophenon hydrochloride with cipher PS1, were carried out on rats as well as follow-up of development of drug dependence after continuous usage of the substance. The obtained showed that the compound S1 had stimulating influence on the central nervous system of amphetamine-like type. After prolonged administration of amphetamine and the compound PS1 it was established in rats that amphetamine induced development of tolerance and occurrence of hypersensitivity during withdrawal. The compound PS1 did not cause similar changes in rats after its chronic administration.

: Neuronal excitotoxicity and metabolic decline, which begin in the early stages of Alzheimer's disease (AD), pose challenges for effective amelioration. Our previous work suggested that the natural compound xanthohumol, the most abundant prenylated flavonoid in hops, prevents memory deficits in APP/PS1 mice; however, the underlying mechanisms remain unclear. : This study utilized APP/PS1 mice and cutting-edge omics techniques to investigate the effects of xanthohumol on hippocampal proteome, serum metabolome, and microbiome.

Diabetes is a major risk factor for Alzheimer's disease (AD). Amino acid compound 2 (AAC2) improves glycemic and cognitive functions in diabetic mouse models through mechanisms distinct from insulin. Our goal was to compare the effects of AAC2, insulin, and their nanofiber-forming combination on early asymptomatic AD pathogenesis in APP/PS1 mice.

Current therapies for Alzheimer's disease (AD) do not delay its progression, therefore, novel disease-modifying strategies are urgently needed. Recently, an increasing number of compounds from natural origin with protective properties against AD have been identified. Mixtures or extracts obtained from natural products containing several bioactive compounds have multifunctional properties and have drawn the attention because multiple AD pathways can be simultaneously modulated.
