Synthesis of the azaoxoaporphine alkaloid sampangine and ascididemin-type pyridoacridines through TMPMgCl·LiCl-mediated ring closure

We report the synthesis of the azaoxoaporphine alkaloid sampangine (4) and a series of ring A analogues and isomers of the marine pyridoacridine alkaloid ascididemin (2). This approach starts from readily available 1-bromo[2,7]naphthyridine (12) or 4-bromobenzo[c][2,7]naphthyridine (5), and the ring A scaffold bearing an ester moiety is introduced by a Suzuki or Negishi cross-coupling reaction. The final cyclization step was achieved through a directed remote ring metallation with the Knochel-Hauser base (TMPMgCl·LiCl; TMP = 2,2,6,6-tetramethylpiperidinyl), followed by intramolecular trapping of the ester group.

4- Substituted sampangine derivatives: Novel acetylcholinesterase and β-myloid aggregation inhibitors

A series of 4- substituted sampangine derivatives (4-aminoalkylaminosampangine Ar–NH(CH2)nNR1R2) has been designed, synthesized, and tested for their ability to inhibit acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and β-myloid (Aβ) aggregation. The synthetic compounds exhibited high AChE inhibitory activity and a significant in vitro inhibitory potency toward the self-induced Aβ aggregation. While, treatment of SH-SY5Y cells overexpressing the Swedish mutant form of human β-amyloid precursor protein (APPsw) with derivatives was associated with significant reduction of Aβ42 secretion levels. Moreover, most of the synthetic compounds were predicted to be able to cross the blood-brain barrier (BBB) to reach their targets in the central nervous system (CNS) according to a parallel artificial membrane permeation assay for BBB. The result encourages us to study this class of compounds thoroughly and systematically.
