The new pyridazine containing iron complexes, [N,N,N?,N?-tetrakis(3-pyridazylmethyl)propylenediamine]iron(II)(PF6)2 (1) and [N,N?-bis(2-pyridazylmethyl)-N,N?-bis(2-pyridylmethyl)propylenediamine]iron(II) (PF6)2 (2) were synthesized and their reactivity towards protonation was compared to that of the analogous tetrapyridine complex [N,N,N?,N?-tetrakis(2-pyridylmethyl)propylenediamine]iron(II)(PF6)2 (3). The solution and solid-state structures were confirmed by NMR and X-ray crystallographic studies. For 1?3, the ligands bind in a hexadentate fashion giving similar octahedral structures with an N6 coordination environment. Across the series, the increasing number of pyridazines has only modest effects on the spectroscopic and electrochemical properties of the metal. Nevertheless, their reactivity towards protonation is drastically different. While 2 and 3 decompose in the presence of strong acids, 1 is able to be stably protonated as a result of cooperative second sphere interactions.

Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. Application of 187973-60-0

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.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.
