The H 1R predominantly couples to Gα q/11 proteins and upon receptor activation progresses mainly through the inositol-phospholipid-dependent pathway with a subsequent increase in intracellular Ca 2+ concentration. The histamine H 1 receptor (H 1R), a class A G protein-coupled receptor (GPCR), is one of four histamine receptor subtypes found in humans. Molecular docking of 31a with the human H 1R predicts that the optimized peptide linker makes interactions with key residues in the receptor. Compound 31a, both potent and subtype-selective, enabled H 1R visualization using confocal microscopy at a concentration of 10 nM. Incorporation of a boron-dipyrromethene (BODIPY) 630/650-based fluorophore conferred high binding affinity to our H 1R fluorescent ligands, remarkably overriding the linker SAR observed in corresponding unlabeled congeners.

Here, we report a series of high-affinity H 1R fluorescent ligands varying in peptide linker composition, orthosteric targeting moiety, and fluorophore. We previously reported a H 1R fluorescent ligand, bearing a peptide-linker, based on antagonist VUF13816 and sought to further explore structure–activity relationships (SARs) around the linker, orthostere, and fluorescent moieties. The NMR spectra of four-membered carbocyclic ring systems.The histamine H 1 receptor (H 1R) has recently been implicated in mediating cell proliferation and cancer progression therefore, high-affinity H 1R-selective fluorescent ligands are desirable tools for further investigation of this behavior in vitro and in vivo.
