- Substituted tetrahydroisoquinolines: synthesis, characterization, antitumor activity and other biological properties
-
This work deals with the molecular design, synthesis and biological activity of a series of tetrahydro[1,4]dioxanisoquinolines and dimethoxyisoquinoline analogues. This study describes the synthesis strategy of these potential antitumor compounds, their multi-step synthesis and their optimization. A series of tetrahydroisoquinolines was synthesized and their cytotoxicity evaluated. Some of these tetrahydroisoquinolines showed promising KRas inhibition, antiangiogenesis activity and antiosteoporosis properties. Molecular modeling studies showed that compound 12 bind in the p1 pocket of the KRas protein making interactions with the hydrophobic residues Leu56, Tyr64, Tyr71 and Thr74 and hydrogen bonds with residues Glu37 and Asp38.

- 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 total synthesis 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-HT 1A and 5-HT2A receptors were determined. Compounds 18k and 18m were identified as partial agonists at the D1 receptor with Ki values of 50 and 6.3 nM, while both compounds act as D2 receptor antagonists (Ki = 305 and 145 nM, respectively) and 5-HT1A receptor full agonists (Ki = 149 and 908 nM, respectively). These two THPBs compounds exerted antipsychotic actions in animal models. Further electrophysiological studies employing single-unit recording in intact animals demonstrated that 18k-excited dopaminergic (DA) neurons are associated with its 5-HT1A receptor agonistic activity. These results suggest that these two compounds targeted to multiple neurotransmitter receptors may present novel lead drugs with new pharmacological profiles for the treatment of schizophrenia.

- Synthesis of isoquinolines and tetrahydroisoquinolines as potential antitumour agents
-
The isoquinoline 17 and the tetrahydroisoquinoline 16 were synthesized from 2,3-dihydro-1,4-benzodioxin (1) by different synthetic strategies. Preparation of arylethylamines and their cyclization in Bischler-Napieralski conditions have been studied. Another approach to isoquinolines was based on the amination of the ketone 13 followed by cyclization in acidic media. The route via the amide 15 was found to be more successful with respect to both yield and ease of reaction.

- Process for the preparation of (8As,12AS,13AS)-decahydroisoquino ((2,1-G) (1,6)-naphthyridin-8-one derivatives
-
The invention provides a process for preparing single enantiomers of compounds represented by the formula: STR1 and chiral acid addition salts thereof; wherein: X and Y are independently hydrogen; lower alkyl; lower alkoxy; or halo; or X and Y taken together is methylenedioxy or ethylene-1,2-dioxy; which includes reduction of a compound represented by the formula: STR2 to give a mixture of stereoisomers represented by the formula: STR3 wherein each wavy line independently represents a bond in either the α or β position; followed by dissolving the mixture of stereoisomers and a chiral resolving acid in a suitable solvent and allowing the solution to crystallize, giving a salt of the desired enantiomer.
