ECTONUCLEOTIDE PYROPHOSPHATASE-PHOSPHODIESTERASE-1 INHIBITORS AND PHARMACEUTICAL COMPOSITIONS COMPRISING THE SAME
摘要:
The present disclosure relates compounds for inhibiting ectonucleotide pyrophosphatase/phosphodiesterase-1 (ENPP-1), or a pharmaceutically acceptable salts thereof.
Suzuki–Miyaura cross-coupling reaction followed by the base-mediated ring closure to pyrrole formation. Synthesis of a series of γ-carboline derivations from the 4-brominated γ-carboline 4a has been achieved by employing various coupling reactions and N-alkylations. This method has been applied for the synthesis of the antimalarial and anticancer natural product isocryptolepine. The photophysical properties

A general synthetic route to prepare all four carboline regioisomers by photo stimulated cyclization of anilinohalopyridines is described. The methodology affords various substituted carbolines in good to excellent yields. In the case of alpha-carbolines, the S(RN)1 methodology complements previously reported palladium-catalyzed cyclization approaches.

Lewis acid-directed cyclocondensations of piperidone enol ethers with 2-methoxy-4-(N-phenylsulfonyl)-1,4-benzoquinoneimine are reported. Benzofurans are obtained with BF3. OEt2 as a promoter, whereas use of excess amounts of TiCl4:Ti(OiPr)(4) leads to tetrahydrocarbolines. The latter reactions provide expedient routes to oxygen-substituted tetrahydrocarbolines and carbolines. As applications of this new methodology, the preparations of 1-[3-(dimethylamino)propyl] amino-7-methoxy- and 1-[3-(dimethylamino)propyl]amino-7,8-dimethoxy-5H-pyrido[4,3-b]indoles are described.
