Osteosarcoma (OS) is the most common malignancy of the skeletal system, with a poor prognosis and high rate of recurrence. Adequate surgical margin and adjuvant chemotherapy improve the overall survival and limb salvage rate of osteosarcoma patients. Previous studies have showed that OS exhibits an increase in the expression of proviral integration site for Moloney murine leukemia virus 1 (PIM1) kinase, and high levels of PIM1 are also associated with poor OS prognosis and metastasis. We exploited the overexpression of proto-oncogenic PIM1 in OS towards the development of a novel near-infrared imaging and targeted therapeutic agent, namely QCAi-Cy7d by conjugating a PIM1 small molecule inhibitor and heptamethine cyanine dye, for simultaneous guiding surgery and chemotherapy. QCAi-Cy7d showed targeted imaging and anticancer activities against OS in vitro and vivo without any obvious toxicity, and its antitumoral activity was much greater than the parent PIMI inhibitor. These results demonstrated the potential of new conjugate of PIM1 inhibitor and near-infrared imaging, supporting structure-based design and development of theranostic agents for precise tumor imaging and targeted treatment.

We identified a new series of quinoxaline-2-carboxylic acid derivatives, targeting the human proviral integration site for Moloney murine leukemia virus-1 (HsPim-1) kinase. Seventeen analogues were synthesized providing useful insight into structure-activity relationships studied. Docking studies realized in the ATP pocket of HsPim-1 are consistent with an unclassical binding mode of these inhibitors. The lead compound 1 was able to block HsPim-1 enzymatic activity at nanomolar concentrations (IC50 of 74 nM), with a good selectivity profile against a panel of mammalian protein kinases. In vitro studies on the human chronic myeloid leukemia cell line KU812 showed an antitumor activity at micromolar concentrations. As a result, compound 1 represents a promising lead for the design of novel anticancer targeted therapies.

Anti-folate agents had a significant impact on therapeutic treatment plans for diseases such as cancer, and bacterial and parasitic infections, notably malaria. Quinoxaline derivatives showed in vitro anticancer activity and were able to inhibit both the dihydrofolate reductase and thymidylate synthase. Here, we decided to combine the chemical properties of quinoxalines and quinoxaline 1,4-dioxides with those of benzotriazole nucleus with the aim to evaluate the resulting biological properties. Two main new series, including more than 60 compounds, were prepared. In the first one, the benzotriazole moiety was linked through the nitrogen atoms 1, 2, or 3, to a glutaric acid substituent to simulate a glutamic moiety. In the second series, the glutaric acid was substituted with acetic acid moiety to evaluate the effects of steric hindrance. Here, we describe the multistep chemical processes to obtain all titled quinoxalines starting from commercially available diamines. The classical oxidation of selected quinoxalines was unsuccessful, and we have come to an independent synthetic pathway to obtain new derivatives linked to the benzotriazole moieties starting from synthons bearing N-oxide functionality.

(Chemical Equation Presented) Derivatives of the hitherto unknown ring system, pyrazolo[4′,3′:5,6]pyrano[2,3-b]quinoxalin-4(1H)-one, are synthesized in one step from the corresponding 1-substuituted or 1,3-disubstituted 2-pyrazolin-5-ones and 3-chloroquinoxaline-2-carbonyl chloride using calcium hydroxide in boiling 1,4-dioxane. The parent system carrying no substituent in positions 1 and 3 is obtained upon treatment of the 1-PMB (p-methoxybenzyl) protected congener with trifluoroacetic acid. Detailed NMR spectroscopic investigations including unambiguous chemical shift assignments of all 1H, 13C, and 15N resonances of the obtained tetracycles are reported.
