A series of sulfone analogs of donepezil were designed and synthesized as novel acetylcholinesterase (AChE) inhibitors with the potent inhibiting Aβ aggregation and providing neuroprotective effects as potential modalities for Alzheimer's disease (AD). Most of the target compounds displayed effective inhibition of AChE, especially compound 24r which displayed powerful inhibitory activity (IC50 = 2.4 nM). Kinetic and docking studies indicated that compound 24r was a mixed-type inhibitor. Furthermore, in glyceraldehyde (GA)-exposed SH-SY5Y differentiated neuronal cells, compound 24r could potently inhibit AChE, reduce tau phosphorylation at S396 residue, provide neuroprotection by rescuing neuronal morphology and increasing cell viability. It was also found to reduce amyloid aggregation in the presence of AChE. In addition, compound 24r showed evident protections from mitochondrial membrane dysfunction and oxidative stress in okadaic acid-induced pharmacological models. Moreover, compound 24r exhibited more effective treatment prospects in vivo than donepezil, including a moderate blood-brain barrier permeability, a more potent AChE inhibitory activity and behavioral improvement in scopolamine-induced cognition-impaired mice model at a much lower dose. Collectively, compound 24r is a promising lead compound for further investigation to discovery and development of new anti-AD agents.

A class of benzopyranopyrazolyl derivatives is described for use in treating inflammation and inflammation-related disorders. Compounds of particular interest are defined by Formula I STR1 wherein A is --(CH2)m --X--(CH2)n --; wherein X is S(O)p or O; wherein m is 0 or 1; wherein n is 0 or 1; wherein p is 0 or 1; wherein B is selected from phenyl and five and six membered heteroaryl; wherein R1 is selected from lower haloalkyl, cyano, formyl, lower alkoxycarbonyl, lower alkoxy, lower N-alkylaminocarbonyl, N-phenylaminocarbonyl, lower N,N-dialkylaminocarbonyl and lower N-alkyl-N-phenylaminocarbonyl; wherein R2 is phenyl substituted at a substitutable position with a radical selected from lower alkylsulfonyl and sulfamyl; and wherein R4 is one or more radicals selected from hydrido, halo, lower alkylthio, lower alkylsulfinyl, lower alkyl, cyano, carboxyl, lower alkoxycarbonyl, aminocarbonyl, lower haloalkyl, hydroxyl, lower alkoxy, amino, lower N-alkylamino, lower N,N-dialkylamino, lower hydroxyalkyl and lower haloalkoxy; or a pharmaceutically-acceptable salt thereof.
