- A Continuous Flow Strategy for the Facile Synthesis and Elaboration of Semi-Saturated Heterobicyclic Fragments
-
An efficient hydrogenation protocol under continuous flow conditions was developed for the synthesis of underrepresented semi-saturated bicyclic fragments containing highly sp3-rich skeletons for fragment-based drug discovery (FBDD) programs. Excellent yields were generally achieved by using Pd/C (10 % w/w) and RaNi at 25–150 °C under 4–100 bar of hydrogen pressure. The generated fragments, with appropriate physicochemical properties, present diverse hydrogen-bonding pharmacophores and useful vectors for their synthetic elaboration in the optimization stage. Successive, simple functionalizations in continuous flow were accomplished to demonstrate the opportunity to develop multi-step continuous flow synthesis of valuable starting points for FBDD campaigns. A conclusive quality control (QC) was essential to discard those structures which do not fit the typical fragment library parameters.

- Design, synthesis, and structure-activity relationship studies of novel fused heterocycles-linked triazoles with good activity and water solubility
-
Triazoles with fused-heterocycle nuclei were designed and evaluated for their in vitro activity on the basis of the binding mode of albaconazole using molecular docking, along with SAR of antifungal triazoles. Tetrahydro-[1,2,4] triazolo[1,5-a]pyrazine and tetrahydro-thiazolo[5,4-c]pyridine nuclei were preferable to the other four fused-heterocycle nuclei investigated. Potent in vitro activity, broad spectrum and better water solubility were attained when triazoles containing nitrogen aromatic heterocycles were attached to these two nuclei. The most potent compounds 27aa and 45x, with low hERG inhibition and hepatocyte toxicity, both exhibited excellent activity against Candida, Cryptococcus, and Aspergillus spp., as well as selected fluconazole-resistant strains. A high water-soluble compound 58 (the disulfate salt of 45x) displayed unsatisfactory in vivo activity because of its poor PK profiles. Mice infected with C.alb. SC5314 and C.alb. 103 (fluconazole-resistant strain) and administered with 27aa displayed significantly improved survival rates. 27aa also showed favorable pharmacokinetic (PK) profiles.

- Scaffold hopping approach to a new series of smoothened antagonists
-
The hedgehog (Hh) signaling pathway is a key regulator during embryonic development, while in adults, it has limited functions such as stem cell maintenance and tissue repair. The aberrant activity of the Hh signaling in adults has been linked to numerous human cancers. Inhibition of Hh signaling therefore represents a promising approach toward novel anticancer therapies. The Smoothened (Smo) receptor mediates Hh signaling. Here we report a new series of Smo antagonists which were obtained by a scaffold hopping strategy. Compounds from this new scaffold demonstrated decent inhibition of Hh pathway signaling. The new scaffold can serve as a starting point for further optimization.

- HEDGEHOG PATHWAY SIGNALING INHIBITORS AND THERAPEUTIC APPLICATIONS THEREOF
-
The hedgehog (Hh) signaling pathway is a pathway which regulates patterning, growth and cell migration during embryonic development, but in adulthood is limited to tissue maintenance and repair. Mutational inactivation of the inhibitory pathway components leads to constitutive ligand-independent activation of the Hh signaling pathway, results in cancers such as basal cell carcinoma and medulloblastoma. Ligand-dependent activation of Hh signaling is involved in prostate cancer, pancreatic cancer, breast cancer and blood cancers. Therefore, inhibition of the aberrant Hh signaling represents a promising approach toward novel anticancer therapy. The invention provides novel molecules of formula I that inhibit hedgehog pathway signaling and provides therapeutic applications for the treatment of malignancies (basal cell carcinoma, medulloblastoma, glioblastoma, non-small cell lung cancer, prostate cancer, pancreatic cancer, blood cancers, mesenchymal cancers, etc.), prevention of tumor regrowth, sensitization of radio-chemo therapies, and other diseases (inflammation, fibrosis and immune disorders).

Les derives N-nitres et N-nitroses en serie tetrahydro-5,6,7,8 imidazopyrazinique sont obtenus simultanement lors de la nitration par HNO3 (d = 1.51) en milieu sulfurique.L'analyse des isomeres N-nitroses Z et E met en evidence l'apparition preponderante de la forme Z ainsi qu'une restriction importante a son equilibration.La stabilite particuliere de l'isomere Z est attribuee a l'existence d'une assistance electronique preferentielle entre groupement nitroso et protons en position 8.
