Synthesis and identification of novel pyridazinylpyrazolone based diazo compounds as inhibitors of human islet amyloid polypeptide aggregation

We have carried out a docking inspired synthesis and screening of a library of diazenyl-derivatives of pyridazinylpyrazolone molecules for their ability to modulate the amyloidogenic self-assembly of human islet amyloid polypeptide (hIAPP). hIAPP is a 37-residue peptide which is involved in glycemic control along with insulin. Its extracellular fibrillar assemblies in pancreatic beta-cells are responsible for type 2 diabetes. A three-step synthetic scheme was used to prepare these novel compounds using 2-(6-chloropyridazin-3-yl)-5-methyl-2,4-dihydro-3H-pyrazol-3-one as a key intermediate that was reacted with various diazo electrophiles to generate a library of compounds with yields ranging from 64 to 85%. The effect of the compounds on hIAPP amyloid fibril formation was evaluated with a thioflavin T (ThT) fluorescence-based kinetic assay. Furthermore, TEM imaging was carried out to corroborate the interactions of the compounds with hIAPP and subsequent hIAPP inhibition at the different level of fibrillization. The CD spectroscopy showed that upon incubation with SSE15314 for 12 h, the percentage of alpha-helices was maintained to a level of hIAPP at 0 h. The current study presents identification and characterization of SSE15314 as the hit, which completely inhibited the fibril formation and can be further optimized into a lead compound.

Design of annulated pyrazoles as inhibitors of HIV-1 reverse transcriptase

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are recommended components of preferred combination antiretroviral therapies used for the treatment of HIV. These regimens are extremely effective in suppressing virus replication. Structure-based optimization of diaryl ether inhibitors led to the discovery of a new series of pyrazolo[3,4-c]pyridazine NNRTIs that bind the reverse transcriptase enzyme of human immunodeficiency virus-1 (HIV-RT) in an expanded volume relative to most other inhibitors in this class. The binding mode maintains the beta313 and beta14 strands bearing Pro236 in a position similar to that in the unliganded reverse transcriptase structure, and the distribution of interactions creates the opportunity for substantial resilience to single point mutations. Several pyrazolopyridazine NNRTIs were found to be highly effective against wild-type and NNRTI-resistant viral strains in cell culture.
