Heme oxygenase-1 (HO-1) is a cytoprotective enzyme and a survival-enhancing factor in a number of cancers. Chronic myeloid leukemia (CML) is a blood cancer caused by pathological kinase activity of the BCR-ABL protein, currently treated with tyrosine kinase inhibitors (TKIs) such as Imatinib (IM). However, resistance to TKIs persists in a number of patients and HO-1 overexpression has been linked with the induction of chemoresistance in CML. With this in mind, in this study, we designed and synthesized the first series of hybrid compounds obtained by combining the structures of IM, as BCR-ABL inhibitor, with imidazole-based HO-1 inhibitors. We found that many hybrids were able to inhibit the enzymatic activity of both targets and to reduce the viability of CML-IM resistant cells, showing that a single molecular entity may reduce the resistance phenomenon.

In the present study, a series of benzamides, endowed with potent dopamine D2, serotonin 5-HT1A and 5-HT2A receptors properties, was synthesized and evaluated as potential antipsychotics. Among them, 3-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl)-piperidin-1-yl)butoxy)-N-methylbenzamide (21) and its fluoro-substituted analogue (22) held the best pharmacological binding profiles. They not only presented potent activities for D2, 5-HT1A, and 5-HT2A receptors, but were also endowed with low activities for 5-HT2C, H1 receptors and hERG channels, suggesting a low propensity of inducing weight gain and QT prolongation. In animal models, compounds 21 and 22 reduced phencyclidine-induced hyperactivity with a high threshold for catalepsy induction. It thus provides potential candidates for further preclinical studies.

As part of our ongoing small-molecule metabotropic glutamate (mGlu) receptor positive allosteric modulator (PAM) research, we performed structure-activity relationship (SAR) studies around a series of group II mGlu PAMs. Initial analogues exhibited weak activity as mGlu2 receptor PAMs and no activity at mGlu3. Compound optimization led to the identification of potent mGlu2/3 selective PAMs with no in vitro activity at mGlu1,4-8 or 45 other CNS receptors. In vitro pharmacological characterization of representative compound 44 indicated agonist-PAM activity toward mGlu2 and PAM activity at mGlu 3. The most potent mGlu2/3 PAMs were characterized in assays predictive of ADME/T and pharmacokinetic (PK) properties, allowing the discovery of systemically active mGlu2/3 PAMs. On the basis of its overall profile, compound 74 was selected for behavioral studies and was shown to dose-dependently decrease cocaine self-administration in rats after intraperitoneal administration. These mGlu2/3 receptor PAMs have significant potential as small molecule tools for investigating group II mGlu pharmacology.
