7-fluoro-6-morpholino-3-phenylquinolin-1-ium chloride 2 has been synthesized and characterised by various spectral and electrochemical studies besides its molecular structure determination by a single-crystal X-ray diffraction investigation. Computational studies by Austin Model-1 (AM1), SCF-MM2 and DFT/B3LYP to compare the structural data with the single crystal XRD data have been performed on the cation of 2. The compound is found to crystallize in a monoclinic system in space group P21/c with crystal data as a = 11.0497(4) ?, b = 8.8712 (3) ?, c = 17.5099 (5) ?, β = β = 97.605 (17), V = 1701.3 (10) ?3, Z = 4, density = 1.346 Mg/m3, F (000) = 720, T = 293 K. Hirshfeld surface plots and fingerprint plots are obtained on 2 which show hydrogen bond intermolecular interactions. Electrochemical studies reveal that 2 undergoes diffusion-controlled irreversible anodic electron transfer and that it fluoresces at 520 nm with an absorption at ～ 430 nm. The molecular docking of 2 on EGFR-TK protein and its cell viability assay on hypopharyngeal cancer cell line (FaDu) through MTT assay promise a scope of using compound 2 as an anticancer drug.

The heme enzyme indoleamine 2,3-dioxygenase 1 (IDO1) plays an essential role in immunity, neuronal function, and aging through catalysis of the rate-limiting step in the kynurenine pathway of tryptophan metabolism. Many IDO1 inhibitors with different chemotypes have been developed, mainly targeted for use in anti-cancer immunotherapy. Lead optimization of direct heme iron-binding inhibitors has proven difficult due to the remarkable selectivity and sensitivity of the heme-ligand interactions. Here, we present experimental data for a set of closely related small azole compounds with more than 4 orders of magnitude differences in their inhibitory activities, ranging from millimolar to nanomolar levels. We investigate and rationalize their activities based on structural data, molecular dynamics simulations, and density functional theory calculations. Our results not only expand the presently known four confirmed chemotypes of sub-micromolar heme binding IDO1 inhibitors by two additional scaffolds but also provide a model to predict the activities of novel scaffolds.

In this paper, we present a novel charge-free fluorescence-switchable near-infrared (IR) dye based on merocyanine for target specific imaging. In contrast to the typical bathochromic shift approach by extending π-conjugation, the bathochromic shift of our merocyanine dye to the near-IR region is due to an unusual S-cis diene conformer. This is the first example where a fluorescent dye adopts the stable S-cis conformation. In addition to the novel bathochromic shift mechanism, the dye exhibits fluorescence-switchable properties in response to polarity and viscosity. By incorporating a protein-specific ligand to the dye, the probes (for SNAP-tag and hCAII proteins) exhibited dramatic fluorescence increase (up to 300-fold) upon binding with its target protein. The large fluorescence enhancement, near-IR absorption/emission, and charge-free scaffold enabled no-wash and site-specific imaging of target proteins in living cells and in vivo with minimum background fluorescence. We believe that our unconventional approach for a near-IR dye with the S-cis diene conformation can lead to new strategies for the design of near-IR dyes.
