Development and Characterization of a Fluorescent Probe for GLS1 and the Application for High-Throughput Screening of Allosteric Inhibitors

Glutaminase (GLS1) is a cancer energy metabolism protein which plays a predominant role in cell growth and proliferation. Because of its major involvement in malignant tumor, small-molecule GLS1 inhibitors are urgently needed to assess its therapeutic potential and for probing their underlying biology function. Recent studies showed that targeting the allosteric binding site represented a promising strategy for identifying potent and selective GLS1 inhibitors. Herein, we present the synthesis of two fluorescent probes targeting the allosteric binding site of GLS1 and their usage as mechanistic tools in multiple applicable assay platform. The fluorescence polarization (FP)-based binding assay enables easy, fast, and reliable screen of allosteric inhibitors from our in-house compound library obtained through click chemistry method. The obtained compound C147 (named as CPU-L1) has been proved to be more potent and with greater solubility than the control compound CB839, which could serve as promising leads for further optimization as novel GLS1 inhibitors.

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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2164-61-6 is helpful to your research. Synthetic Route of 2164-61-6

Studies on agents with vasodilator and beta-blocking activities. II

A series of phenoxypropanolamines having a hydrazinopyridazinyl moiety was synthesized. Their hypotensive and beta-blocking activities were evaluated after intravenous administration of the compounds to anesthetized rats. Some of them exhibited both activities. In particular, compound 20k is a candidate for clinical use due to its hypotensive activity, equal to that of hydralazine, and its beta-blocking activity, 2.7-fold more potent than that of propranolol.
