Abstract:

A series of 2-arylamino-1,3,5-triazine derivatives (4a4g), which were designed and synthesized via Sonogashira coupling reaction, were evaluated using two-electrode voltage clamp (TEVC) recordings of human α7 nAChR expressed in Xenopus ooctyes. Compound 4g as a positive allosteric modulator (PAM) showed better efficacy than lead compound 3 (HZZ-A-11) with an EC50 value of 1.23 ± 0.41 μM. Further pharmacological evaluation of compound 4g might lead to the developmental potential for therapy of cognitive deficits commonly shared by neuropsychiatric disorders, such as schizophrenia and Alzheimer’s disease.

Key words: Cognitive deficit, α7 nAChR, Positive allosteric modulators, Sonogashira coupling reaction
