Imidazopyridine-5,6,7,8-tetrahydro-8-quinolinamine derivatives with potent activity against HIV-1

Synthesis of several novel imidazopyridine-5,6,7,8-tetrahydro-8-quinolinamine derivatives with potent activity against HIV are described. Synthetic approaches allowing for variation of the substitution pattern are outlined and resulting changes in antiviral activity and pharmacokinetics are highlighted. Several compounds with low nanomolar anti-HIV activity and oral bioavailability are described.

Substituted tetrahydrocarbazoles with potent activity against human papillomaviruses

The synthesis and SAR of a series of substituted 1-aminotetrahydrocarbazoles with potent activity against human papillomaviruses are described. Synthetic approaches allowing for variation of the substitution pattern of the tetrahydrocarbazole are outlined and resulting changes in antiviral activity are highlighted. Several compounds with in vitro antiviral activity (W12 antiviral assay) in the low nanomolar range were identified and (1R)-6-bromo-N-[(1R)-1-phenylethyl]-2,3,4,9-tetrahydro-1H-carbazole-1-amine was selected for further evaluation.

Synthesis of a novel tricyclic 1,2,3,4,4a,5,6,10b-octahydro-1,10-phenanthroline ring system and CXCR4 antagonists with potent activity against HIV-1

Stereorandom and diastereoselective syntheses of a novel 1,2,3,4,4a,5,6,10b-octahydro-1,10-phenanthroline ring system are described. Derivatives of all four diastereomers were prepared and isolated in >98% ee. The pure enantiomers were compared in order to determine the preferred absolute and relative configuration required for optimal anti-HIV activity. Anti-HIV potency and pharmacokinetic properties of the newly synthesized tricyclic octahydrophenanthroline inhibitors are presented and comparisons are made to previously reported bicyclic (8S)-N-methyl-5,6,7,8-tetrahydro-8-quinolinamine analogs.

Tetrahydrocarbazole amides with potent activity against human papillomaviruses.

Synthesis of a series of tetrahydrocarbazole amides with potent activity against human papillomaviruses is described. Synthetic approaches allowing for variation of the substitution pattern of the tetrahydrocarbazole and the amide are outlined and resulting changes in antiviral activity and certain developability parameters are highlighted. Several compounds with in vitro antiviral activity (W12 antiviral assay) in the single digit nanomolar range were identified and N-[(1R)-6-chloro-2,3,4,9-tetrahydro-1H-carbazol-1-yl]-2-pyridinecarboxamide was selected for further evaluation.

Novel heterocyclic scaffolds of GW4064 as farnesoid X receptor agonists.

The farnesoid X receptor (FXR) may play a crucial role in a number of metabolic diseases and, as such, could potentially serve as a target for the development of therapeutics as a treatment for those diseases. Previous work has described GW4064 as an FXR agonist with an interesting activity profile. This manuscript will describe the synthesis of novel analogs of GW4064 and the activity profile of those analogs.

N-{3-[(1,1-dioxido-1,2-benzothiazol-3-yl)(phenyl)amino]propyl}benzamide analogs as potent Kv1.3 inhibitors. Part 1.

We report the synthesis and in vitro activity of a series of novel N-{3-[(1,1-dioxido-1,2-benzothiazol-3-yl)(phenyl)amino]propyl}benzamide analogs. These analogs showed potent inhibitory activity against Kv1.3. Several compounds, including compound 8b, showed similar potency to the known Kv1.3 inhibitor PAP-1 when tested under the IonWorks patch clamp assay conditions.
