Alzheimer's disease (AD) is a complex neurodegenerative disease with multiple pathological features. Multifunctional compounds able to simultaneously interact with several pathological components have been considered as a solution to treat the complex pathologies of neurodegenerative diseases. β-carboline and cinnamic acid have been extensively studied for their widespread biological effects in treatment of AD, further application is limited due to its poor solubility and high toxicity. Herein, a series of carboline-cinnamic acid hybrids was designed and synthesized to obtain new multifunctional molecules with low toxicity and good physicochemical properties. In particular, e3 and e12 exhibited significant inhibition of Aβ aggregation (inhibitory rate at 25 μM: 65% and 72% respectively), moderate BuChE inhibition, excellent neuroprotective effects and low neurotoxicity. Furthermore, in the AD mice model, e3 and e12 could restore learning and memory function to a comparable level to that of the control and did not exhibit any acute toxicity in vivo at a relatively high dose of 600 mg/kg. Thus, these new compounds can be further studied as multifunctional molecules for AD.

Thermolysis of 2-vinylindole derivative (1) led to indolylacrylonitrile (6) instead of β-carboline alkaloid isoharmine (4). Latter was prepared by following the conventional method and was fully characterized.
