ITI-007

A great deal has been achieved in the treatment of schizophrenia in recent decades, especially the treatment of the positive symptoms by targeting dopamine D2 receptors. But the disease has a range of other symptoms which gravely affect quality of life and which require other strategies or additional targets. Among the agents gradually filling the empty therapeutic space is ITI-007, which has an unusual mechanistic profile: it targets 5-HT2A and dopamine D2 receptors, but has a much higher affinity for the former receptors. This may allow the drug’s effects to be modified by dose adjustments, with effects on sleep disturbances, depression and anxiety seen with lower doses and higher doses affecting the positive symptoms of schizophrenia through dopamine D2 receptor modulation. Higher doses can also inhibit serotonin transporters and produce glutamatergic modulation which could improve positive and negative symptoms, depressive symptoms and cognitive impairments. The findings of preclinical studies have supported this view of the drug, and a phase II study found effects on positive and negative symptoms with a safety profile distinct from atypical antipsychotics. Phase III investigation in schizophrenia has begun, and clinical investigation in insomnia and dementia is also under way.

Quinone-based, redox-active resorcin[4]arene cavitands

Catch it if you can! Redox-active resorcin[4]arene cavitands with quinone walls can be reversibly reduced to the hydroquinone form, influencing their host-guest complexation strength. Specifically, a top-covered triptycenequinone cavitand forms kinetically stable complexes with cycloalkanes; this complexation is weaker in the reduced hydroquinone form.

A surprising formation of novel bridged bis-benzimidazoles by oxidation of diaminoquinoxalines

A synthesis of novel hexacyclic bis-benzimidazoles 6 starting from 2,3-diarylamino-quinoxalines via an oxidative cyclization cascade is described. These very stable and high-melting derivatives are featured by their strong fluorescence in the blue region of the visible spectrum. The cyclization reaction between 2,3-dichloroquinoxaline and 1,2-phenylenediamine did not lead to derivatives of type 6. In this case, only fluoflavine 7 was isolated quantitatively.

Evaluation of quinoxaline compounds as ligands of a site adjacent to S2 (AS2) of cruzain

The binding of ten quinoxaline compounds (1?10) to a site adjacent to S2 (AS2) of cruzain (CRZ) was evaluated by a protocol that include a first analysis through docking experiments followed by a second analysis using the Molecular Mechanics-Poisson-Boltzmann Surface Area method (MM-PBSA). Through them we demonstrated that quinoxaline compounds bearing substituents of different sizes at positions 3 or 4 of the heterocyclic ring might interact with the AS2, particularly interesting site for drug design. These compounds showed docking scores (DeltaGdock) which were similar to those estimated for inhibitors that bind to the enzyme through non-covalent interactions. Nevertheless, the free binding energies (DeltaG) values estimated by MM-PBSA indicated that the derivatives 8?10, which bear bulky substituents at position 3 of the heterocycle ring, became detached from the binding site under a dynamic study. Surprisingly, the evaluation of the inhibitory activity of cruzipain (CZ) of some derivatives showed that they increase the enzymatic activity. These results lead us to conclude about the relevance of AS2 as a pocket for compounds binding site, but not necessarily for the design of anti-chagasic compounds.
