Asymmetric total synthesis and identification of tetrahydroprotoberberine derivatives as new antipsychotic agents possessing a dopamine D1, D2 and serotonin 5-HT1A multi-action profile
An effective and rapid method for the microwave-assisted preparation of the key intermediate for the totalsynthesis of tetrahydroprotoberberines (THPBs) including l-stepholidine (l-SPD) was developed. Thirty-one THPB derivatives with diverse substituents on A and D ring were synthesized, and their binding affinity to dopamine D1, D2 and serotonin 5-HT1A and 5-HT2A receptors were determined.

Tetrahydroprotoberbine (THPB) compounds and their use in the treatment of neurological, psychiatric and neurodegenerative diseases is provided. The compounds include d-govadine, l-govadine and racemic govadine, as well as d-THPBs of general formula (I). Enantioselective processes for preparing compounds of formula (I), and d- and l-govadine are also provided.(I)
It is well-known that baicalin-berberine complex (1) precipitates in the water decoction of numerous Chinese Medicinal formulae containing Radix Scutellariae and Rhizoma Coptidis or Cortex Phellodendri. In the current study, ionic interaction between the carboxylate ion of baicalin and the quaternaryammonium ion of berberine was revealed to be responsible for the formation of 1 and wogonoside-berberine
