2015; accepted 18 November 2015 *Present address: Wuhan NO. 1 hospital, Wuhan, Hubei, 430022, China SUM MARY A ims: Chemical entities containing mercapto group have been increasingly attractive in the therapy of central nerve system (CNS) diseases. In the recent study, we screened a series of mercapto-tacrine derivatives with synergistic neuropharmacological proles in vitro. M ethods: We investigated the effect and mechanism of ST09, a thioester derivative of tacrine containing a potential mercapto group, on the vascular dementia (VaD) model of rat induced by bilateral common carotid arteries occlusion (2-VO). Results: ST09 and itsactive metabolite ST10 retained excellent inhibition on acetylcholinesterase (AChE) activity. ST09 signicantly attenuated the 2-VO-induced impairment in spatial acquisition performance and inhibited the 2-VO-induced rise of AChE activity. In the VaD model, ST09 attenuated the oxidative stress and decreased the apoptosis in the cortex and hippocampus. Compared with donepezil, ST09 exhibited a better effect on the regeneration of free thiolsin 2-VO rats. Interestingly, ST09, not donepezil, greatly improved glucose metabolism in various brain regions of 2-VO rats using functional imaging of 1 8 F-labeled uoro-deoxyglucose (FDG) positron emission tomography (PET). Conclusions: ST09 may serve as a more promising agent for the therapy of VaD than tacrine owing to the introduction of a potential mercapto group into the parent skeleton. doi: 10.1111/cns.12495 The rst two authors contributed equally to this work. Introduction Vascular dementia (VaD) is considered as a second most common
cause of dementia after Alzheimers dementia (AD) . The cognitive impairment of VaD is mainly attributed to cerebrovascular pathology . After cerebral hypoperfusion, a series of factors, including metabolism impairment, excitotoxicity, oxidative stress, and cholinergic decit, are involved in the progression of 2016 John Wiley & Sons Ltd secondary cognitive impairment [3,4]. Although some drugs have been approved as moderate therapy for VaD [2,59], none of the clinic drugs show a signicant therapeutic effect on VaD yet. By recognizing the multifactorial nature of VaD, single chemical entity with the ability to modulate multiple targets may offer a promising approach for the treatment of dementia. Tacrine, the rst AChEI approved by the Food and Drug Administration (FDA) for Alzheimers disease (AD), exhibits a CNS Neuroscience & Therapeutics (2016) 110 1 Guang-Nian Zhao, et al., Tmbim1 is a multivesicular body regulator that protects against non-alcoholic fatty liver disease in mice and monkeys by targeting the lysosomal degradation of Tlr 4, Nature Medicine, 2017 (IF=29.9) Pi-Xiao Wang, et al., Targeting CASP8 and FADD-like apoptosis regulator ameliorates nonalcoholic steatohepatitis in mice and nonhuman primates, Nature Medicine, 2017 (IF=29.9)
