Keitaro Suyama, Shuhei Kaneko, Hitoshi Kesamaru, Xiaohui Liu, Ayami Matsushima, Yoshimitsu Kakuta, Takashi Okubo, Kazumi Kasatani, Takeru Nose, Evaluation of the Influence of Halogenation on the Binding of Bisphenol A to the Estrogen-Related Receptor γ, Chemical Research in Toxicology, 10.1021/acs.chemrestox.9b00379, 33, 4, 889-902, 2020.04, Halogenation of organic compounds is one the most important transformations in chemical synthesis and is used for the production of various industrial products. A variety of halogenated bisphenol analogs have recently been developed and are used as alternatives to bisphenol A (BPA), which is a raw material of polycarbonate that has adverse effects in animals. However, limited information is available on the potential toxicity of the halogenated BPA analogs. In the present study, to assess the latent toxicity of halogenated BPA analogs, we evaluated the binding and transcriptional activities of halogenated BPA analogs to the estrogen-related receptor γ(ERRγ), a nuclear receptor that contributes to the growth of nerves and sexual glands. Fluorinated BPA analogs demonstrated strong ERRγbinding potency, and inverse antagonistic activity, similar to BPA. X-ray crystallography and fragment molecular orbital (FMO) calculation revealed that a fluorine-substituted BPA analog could interact with several amino acid residues of ERRγ-LBD, strengthening the binding affinity of the analogs. The ERRγbinding affinity and transcriptional activity of the halogenated BPAs decreased with the increase in the size and number of halogen atom(s). The IC50 values, determined by the competitive binding assay, correlated well with the binding energy obtained from the docking calculation, suggesting that the docking calculation could correctly estimate the ERRγbinding potency of the BPA analogs. These results confirmed that ERRγhas a ligand binding pocket that fits very well to BPA. Furthermore, this study showed that the binding affinity of the BPA analogs can be predicted by the docking calculation, indicating the importance of the calculation method in the risk assessment of halogenated compounds..

Hirofumi Ohga, Fumiko Akase, Ryo Sakanoue, Ayami Matsushima, Kohei Ohta, Michiya Matsuyama, Alanine scanning and characterization of core peptides in Scombridae fish family for construction of Kiss1 super analog, General and Comparative Endocrinology, 10.1016/j.ygcen.2019.113356, 288, 2020.03, Chronic Kiss1 administration strongly promotes gonadal development in immature chub mackerel (cm) (Scomber japonicus). Here, we performed an Alanine scanning (Ala-scanning) of Kiss1 to determine its key residues. Additionally, we examined functional peptides from 16 Scombridae species to develop maturation-inducing super-analogs that can be used universally in Scombridae species. In the Ala-scanning of Kiss1-15 (QDMSSYNFNSFGLRY), substitution of Gln1 and Asp2 did not affect agonistic activity. This suggests that peptides could be downsized. Furthermore, it is possible that Phe8 can be substituted by unnatural amino acids that are difficult to degrade. In molecular cloning, only Scomber showed a 16-residue form as a putative mature peptide. The other genera, did not have a His residue at the N-terminal, which indicated that the functional peptide was 15 residues and the second and third residues from the N-terminal showed variation between interspecies. Next, we examined the binding affinity of various synthetic Kiss1 core peptides in Scombridae interspecies using an SRE-Luc reporter system. We cloned Kiss1 receptors (KissR1) from bluefin tuna (bft) (Thunnus orientalis) and Japanese Spanish mackerel (jsm) (Scomberomorus niphonius) for the first time. In binding affinity with cmKissR1, bftKissR1, and jsmKissR1, the species specificity of the second residue from the N-terminus in each ligand could be ignored, but the difference in the third residue strongly affected receptor binding. Scombridae species possess the same Kiss1 system but the structure of the functional peptide might be species-specific..
3. Takahiro Masuya,Masaki Iwamoto, Xiaohui Liu, Ayami Matsushima, Discovery of novel oestrogen receptor α agonists and antagonists by screening a revisited privileged structure moiety for nuclear receptors, Scientific reports, 10.1038/s41598-019-46272-y, 9, 1, 2019.12, Bisphenol A (BPA) is used as an industrial raw material for polycarbonate plastics and epoxy resins; however, various concerns have been reported regarding its status as an endocrine-disrupting chemical. BPA interacts not only with oestrogen receptors (ERs) but constitutive androstane receptor, pregnane X receptor, and oestrogen-related receptor γ (ERRγ); therefore, the bisphenol structure represents a privileged structure for the nuclear-receptor superfamily. Here, we screen 127 BPA-related compounds by competitive-binding assay using [3H]oestradiol and find that 20 compounds bind to ERα with high affinity. We confirm most of these as ERα agonists; however, four compounds, including bisphenol M and bisphenol P act as novel antagonists. These structures harbour three benzene rings in tandem with terminal hydroxy groups at para-positions, with this tandem tri-ring bisphenol structure representing a novel privileged structure for an ERα antagonist. Additionally, we perform an ab initio calculation and develop a new clipping method for halogen bonding or non-covalent interaction using DV-Xα evaluation for biomolecules..

Xiaohui Liu, Hiroki Sakai, Mitsuhiro Nishigori, Keitaro Suyama, Tasuku Nawaji, Shin Ikeda, Makoto Nishigouchi, Hiroyuki Okada, Ayami Matsushima, Takeru Nose, Miki Shimohigashi, Yasuyuki Shimohigashi, Receptor-binding affinities of bisphenol A and its next-generation analogs for human nuclear receptors, Toxicology and Applied Pharmacology, 10.1016/j.taap.2019.114610, 377, 2019.08, An endocrine-disrupting chemical Bisphenol A (BPA) binds specifically to a nuclear receptor (NR) named ERRγ. Although the importance of receptor-binding evaluation for human NRs is often stressed, the binding characteristics of so-called next-generation (NextGen) bisphenol compounds are still poorly understood. The ultimate objective of this investigation was to evaluate BPA and its NextGen analogs for their abilities to bind to 21 human NRs, the greatest members of NRs for which tritium-labeled specific ligands were available. After establishing the detailed assay conditions for each NR, the receptor binding affinities of total 11 bisphenols were evaluated in competitive binding assays. The results clearly revealed that BPA and the NextGen bisphenols of BPAF, BPAP, BPB, BPC, BPE, and BPZ were highly potent against one or more of NRs such as CAR, ERα, ERβ, ERRγ, and GR, with IC50 values of 3.3–73 nM. These bisphenols were suggested strongly to be disruptive to these NRs. BPM and BPP also appeared to be disruptive, but less potently. BPF exhibited only weak effects and only against estrogen-related NRs. Surprisingly, most doubtful bisphenol BPS was supposed not to be disruptive. The NRs to which BPA and NextGen bisphenols did not bind were RARα, RARβ, RARγ, and VDR. PPARγ, RORα, RORβ, RORγ, RXRα, RXRβ, and RXRγ, exhibited very weak interaction with these bisphenols. The ten remaining NRs, namely, ERRγ, ERβ, ERα, CAR, GR, PXR, PR, AR, LXRβ, and LXRα, showed distinctly strong binding to some bisphenols in this order, being likely to have consequential endocrine-disruption effects..

A Rational Theory Based on Experimental Results for the Missing Pain-Relief Opioid Endomorphin Precursor Gene, ChemBioChem, 10.1002/cbic.201900317, 20, 16, 2054-2058, 2019.01, Endomorphins are neuropeptides that bind strongly to μ-opioid receptors and are considered to play important roles in pain modulation and other biological functions. Two endomorphins have been identified, to date, endomorphine-1 and -2; both are tetrapeptides and differ by only a single amino acid in the third position. Both peptides were isolated from bovine brains; however, their precursor genes have not been identified. In this study, a nucleotide sequence corresponding to the endomorphin-1 peptide in an expressed sequence tag database has been found and a preproendomorphin-like precursor peptide from human brain complementary DNA (cDNA) has been cloned. The cDNA consists of nucleotide sequences of two already annotated predicted genes, and the putative peptide differs by one amino acid from the isolated endomorphin peptides. It is proposed herein that there is the possibility of unknown short proteins or peptide precursors being missed by automated gene prediction programs based on similarities of known protein sequences. A novel concept of how to produce endomorphins from a similar peptide is described. The oxidatively modified base might provide a clue for understanding discrepancies between nucleotide sequences on the genome and those on cDNAs..

It contains Cys(Npys) instead of isovareroyl of a pure antagonist peptide isovareroyl-RYYRIK-NH2. In this study, in order to identify the exact binding site of Cys(Npys), we performed affinity labeling experiments of a series of Cys→Ala mutated ORL1 receptors. A certain number of mutant receptors showed labeling effectiveness weaker than wild type receptor, suggesting that the recepor Cys was labeled by Cys(Npys)-RYYRIK-NH2..

Liu X, Matsushima A, Nakamura M, Costa T, Nose T, Shimohigashi Y, Fine spatial assembly for construction of the phenol-binding pocket to capture bisphenol A in the human nuclear receptor estrogen-related receptor γ., J. Biochem. , 10.1093/jb/mvs008, 151, 4, 403-415, 2012.04, Various lines of evidence have shown that bisphenol A (BPA) acts as an endocrine disruptor that affects various hormones even at merely physiological levels. We demonstrated recently that BPA binds strongly to human nuclear receptor estrogen-related receptor γ (ERRγ), one of 48 nuclear receptors. Based on X-ray crystal analysis of the ERRγ ligand-binding domain (LBD)/BPA complex, we demonstrated that ERRγ receptor residues, Glu275 and Arg316, function as the intrinsic-binding site of the phenol-hydroxyl group of BPA. If these phenol-hydroxyl↔Glu275 and Arg316 hydrogen bonds anchor the A-benzene ring of BPA, the benzene-phenyl group of BPA would be in a pocket constructed by specific amino acid side chain structures. In the present study, by evaluating the Ala-replaced mutant receptors, we identified such a ligand-binding pocket. Leu268, Leu271, Leu309 and Tyr326, in addition to the previously reported participants Glu275 and Arg316, were found to make a receptacle pocket for the A-ring, whereas Ile279, Ile310 and Val313 were found to assist or structurally support these residues. The results revealed that each amino acid residue is an essential structural element for the strong binding of BPA to ERRγ..

Matsushima, A., Nishimura, H., Inamine, S., Uemura, S., Shimohigashi, Y., Capturing of the free cysteine residue in the ligand-binding site by affinity labeling of the ORL1 nociceptin receptor., Bioorg. Med. Chem., 10.1016/j.bmc.2011.10.024 , 19, 7597–7602, 2011.09, All of the δ, μ, and κ opioid receptors have a free thiol group of the Cys residue in the ligand-binding site, although its functional role is not yet known. In order to examine whether or not a similar Cys is also present in the ORL1 nociceptin receptor, we attempted to identify it by affinity labeling using a specific antagonist peptide. We first treated ORL1-expressing COS-7 cell membrane preparations with the thiol-alkylation reagent N-ethylmaleimide (NEM) to perform a binding assay using [(3)H]nociceptin as a tracer and nociceptin, an ORL1 agonist, or Ac-Arg-Tyr-Tyr-Arg-Ile-Lys-NH(2), a nociceptin/ORL1 antagonist, as a competitor. It was suggested that ORL1 has a free Cys in its ligand-binding site, since the NEM treatment reduced the population of ligand-binding sites. This was further confirmed by affinity labeling using Cys(Npys)-Arg-Tyr-Tyr-Arg-Ile-Lys-NH(2) with the SNpys group that can react with a free thiol group, resulting in the formation of a disulfide bond. This affinity labeling was approximately 23 times more specific than NEM alkylation. The results revealed that the ORL1 nociceptin receptor does contain a free Cys residue in the ligand-binding site..

1. @Ayami Matsushima, Halogen-containing Environmental Chemicals Bind to Nuclear Receptors, he 19th Malaysian International Chemistry Congress & International Congress on Pure & Applied Chemistry Langkawi 2018, 2018.10, Environmental chemicals, such as pesticides and raw materials of resins, have the potential to induce adverse effects to wildlife and humans. Most of unfavorable effects derive from signal transduction via activated receptors, which is transmitted by simple ligand-receptor interactions. These receptor-mediated adverse effects are recognized as signal tocxicity, and the chemicals are called endocrine-disrupting chemicals (EDCs). Ligand-receptor interactions are constructed by weak interactions such as electrostatic and hydrophobic interactions, however, the detail mechanism of hydrophobic interactions in biomolecules is still obscure. There are many kinds of receptors, for instance, nuclear receptors in nuclei and membrane receptors on the cell membrane. In this paper, we present structure-activity studies on nuclear receptors and EDCs which are released into the environment. We have a strong interest in -interactions composed of aromatic amino acid residues. The crystal structures of ligands bound to nuclear receptors are also illustrated. We also evaluated the stability of ligand/receptor complexes using some computer calculations. Halogen-containing ligands will also be a useful tool to control receptor-ligand interactions by constructing halogen bonds between receptors and their ligands..
