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.

Electronic and Photophysical Properties of ReI(CO)3Br Complexes Modulated by Pyrazolyl-Pyridazine Ligands

The direct reaction of a series of substituted (1H-pyrazol-1-yl)pyridazine (LI: 6-(1H-pyrazolyl)pyridazine; LII: 3-chloro-6-(1H-pyrazole-1-yl)-pyridazine; LIII: 6-(1H-3,5-dimethylpyrazolyl)pyridazine-3-carboxylic acid; LIV: 3,6-bis-N-pyrazolyl-pyridazine; and LV: 3,6-bis-N-3-methylpyrazolyl-pyridazine) with the bromotricarbonyl(tetrahydrofuran)-rhenium(I) dimer leads to the monometallic complexes [(LX)Re(CO)3Br] (I-V), which displays a nonregular octahedral geometry around the ReI center and a fac-isomerism for the carbonyl groups, whereas pyridazine and pyrazolyl rings remain highly coplanar after coordination to rhenium. Cyclic voltammetry shows one irreversible oxidation and one irreversible reduction for each compound as measured in N,N-dimethylformamide. Oxidation ranges from 0.94 V for III to 1.04 V for I and have been attributed to the ReI/ReII couple. In contrast, the reductions are ligand centered, ranging from -1.64 V for II to -1.90 V for III and V. Density functional theory calculations on the vertical one electron oxidized and one electron reduced species, using the gas-phase optimized geometry for the neutral complex confirm this assignment. Compounds I-V show two absorption bands, one around 410 nm (metal-to-ligand charge transfer (MLCT), Redpi ? pi?) and the other at ?300 nm (intraligand, pi ? pi?). Excitation at 400 nm at 77 K leads to unstructured and monoexponential emission with large Stokes shift, whose maxima vary between 570 (III) and 636 (II) nm. The quantum yields for these emissions in solution are intensified strongly going from air to argon equilibrated solution. Singlet oxygen quantum yields change from 0.03 (III) to 0.21 (IV). These data are consistent with emission from 3MLCT. The emission undergoes a bathochromic shift when R1 is a pi-donating group (Cl or N-pyrazolyl) and a hypsochromic shift for a pi-acceptor (COOH). The bimolecular emission quenching rate constant by triethylamine (TEA) for II, IV, and V is 1.09, 0.745, and 0.583 ¡Á 108 M-1 s-1, respectively. Photolysis in dichloromethane-CO2 saturated solution with TEA as a sacrificial electron donor leads in all cases to formic acid generation.

Lead optimization of 3-carboxyl-4(1 H)-quinolones to deliver orally bioavailable antimalarials

Malaria is a protozoal parasitic disease that is widespread in tropical and subtropical regions of Africa, Asia, and the Americas and causes more than 800,000 deaths per year. The continuing emergence of multidrug-resistant Plasmodium falciparum drives the ongoing need for the development of new and effective antimalarial drugs. Our previous work has explored the preliminary structural optimization of 4(1H)-quinolone ester derivatives, a new series of antimalarials related to the endochins. Herein, we report the lead optimization of 4(1H)-quinolones with a focus on improving both antimalarial potency and bioavailability. These studies led to the development of orally efficacious antimalarials including quinolone analogue 20g, a promising candidate for further optimization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 14161-11-6, you can also check out more blogs about14161-11-6
