Design, synthesis, and biological evaluation of novel tricyclic HIV-1 integrase inhibitors by modification of its pyridine ring
摘要:
This communication details both the syntheses and biological evaluation of a novel class of HIV-1 integrase inbibitors. When the quinoline moiety is replaced with the quinoxoline moiety, the antiviral activity is significantly compromised. Similarly, introduction of imidazole to replace the pyridine ring is deleterious to the potency of the compound against the enzyme. Substitution at the 3-position of the pyridine has been investigated. The presence of the pyridine ring in the tricyclic core is preferred for antiviral activity against HIV integrase.

Direct hydrogenation of a broad variety of cyclic imides to diols and amines using a ruthenium catalyst is reported here. We have applied this strategy toward the development of a new liquid organic hydrogen carrier systembased on the hydrogenation of bis-cyclic imide that is formed by the dehydrogenativecoupling of 1,4-butanediol and ethylenediamine using a new ruthenium catalyst. The rechargeable

A process is provided for the synthesis of a cyclic imide. A primary amine and a diol compound are contacted in the presence of a Ruthenium (II) complex. The Ruthenium (II) catalyst includes at least one of an alicyclic ligand, an aromatic ligand, an arylalicyclic ligand, an arylaliphatic ligand and a phosphine ligand.
