Abstract
Lysergic acid diethylamide (LSD) is a hallucinogenic compound that binds to and activates the serotonin 2A receptor and is classified as a controlled narcotic in Japan. Recently, MiPLA, an N-methyl-N-isopropyl derivative of LSD, has been detected in paper-sheet products in several countries. This study focuses on the synthesis of MiPLA and includes a comprehensive analysis involving structural and liquid chromatography-mass spectrometry (LC-MS). Particularly, MiPLA was synthesized in three-steps starting from ergometrine maleate, which resulted in the formation of (8S)-isomer, iso-MiPLA, as a by-product. The LC-MS results showed that LSD, MiPLA, and iso-MiPLA exhibited different retention times. Their chemical structures were determined using nuclear magnetic resonance spectroscopy, which revealed the presence of rotamers involving the N-methyl-N-isopropyl groups of tertiary amides in MiPLA and iso-MiPLA.

Abstract
Stimulator of interferon genes (STING), a homodimeric membrane receptor localized in the endoplasmic reticulum, plays a pivotal role in signaling innate immune responses. Inhibitors and proteolysis-targeting chimeras (PROTACs) targeting STING are promising compounds for addressing autoinflammatory and autoimmune disorders. In this study, we used a minimal covalent handle recently developed as the ligand portion of an E3 ligase. The engineered STING degrader with a low molecular weight compound covalently binds to STING and E3 ligase. Degrader 2 showed sustained STING degradation activity at lower concentrations (3 µM, 48 h, about 75 % degradation) compared to a reported STING PROTAC, SP23. This discovery holds significance for its potential in treating autoinflammatory and autoimmune diseases, offering promising avenues for developing more efficacious STING-targeted therapies.

Abstract
Proteolysis targeting chimeras (PROTACs) induce the ubiquitination and subsequent proteasomal degradation of targeted proteins. Numerous PROTACs have emerged as promising drug candidates for various disease-related proteins. This study investigates PROTACs targeted to degrade anaplastic lymphoma kinase (ALK) fusion proteins, which are implicated in diseases such as anaplastic large cell lymphoma and non-small cell lung cancer. We recently reported the development of a gilteritinib-warheaded PROTAC to target and degrade the Fms-like tyrosine kinase 3 (FLT3) protein. Gilteritinib is a tyrosine kinase inhibitor that targets FLT3, and recent studies have revealed that it also functions as an ALK inhibitor. We conducted a structure-activity relationship (SAR) study and expanded the range of target proteins for gilteritinib-warheaded PROTACs to include echinoderm microtubule-associated protein-like 4 (EML4)-ALK and nucleophosmin (NPM)-ALK, in addition to FLT3. Our SAR study utilized three types of ligands for E3 ligase- inhibitor of apoptosis protein (IAP), cereblon (CRBN), and von Hippel-Lindau (VHL)- in the PROTAC designs and we observed varied efficacy in the degradation of target proteins. The CRBN-based PROTAC effectively reduced the protein expression of FLT3, EML4-ALK, and NPM-ALK. The IAP-based PROTAC reduced expression of both FLT3 and EML4-ALK proteins but not that of NPM-ALK, while the VHL-based PROTAC was ineffective against all target proteins. Several ALK-targeted PROTACs have already been developed using CRBN or VHL as E3 ligase, but this is the first report of an IAP-based ALK degrader. The length of the linker structure utilized in PROTAC also had a significant effect on their efficacy and activity. PROTACs formed with shorter linkers demonstrated an enhanced degradation activity to target proteins compared with those formed with longer linkers. These findings provide valuable insight for the development of effective PROTACs to target and degrade ALK fusion proteins.

Abstract
The recent discovery of N-nitrosodimethylamine (NDMA), a mutagenic N-nitrosamine, in pharmaceuticals has adversely impacted the global supply of relevant pharmaceutical products. Contamination by N-nitrosamines diverts resources and time from research and development or pharmaceutical production, representing a bottleneck in drug development. Therefore, predicting the risk of N-nitrosamine contamination is an important step in preventing pharmaceutical contamination by DNA-reactive impurities for the production of high-quality pharmaceuticals. In this study, we first predicted the degradation pathways and impurities of model pharmaceuticals, namely gliclazide and indapamide, in silico using an expert-knowledge software. Second, we verified the prediction results with a demonstration test, which confirmed that N-nitrosamines formed from the degradation of gliclazide and indapamide in the presence of hydrogen peroxide, especially under alkaline conditions. Furthermore, the pathways by which degradation products formed were determined using ranitidine, a compound previously demonstrated to generate NDMA. The prediction indicated that a ranitidine-related compound served as a potential source of nitroso groups for NDMA formation. In silico software is expected to be useful for developing methods to assess the risk of N-nitrosamine formation from pharmaceuticals.

Abstract
Proteolysis-targeting chimera (PROTAC) technology is a disruptive innovation in the drug development community, and over 20 PROTAC molecules are currently under clinical evaluation. These PROTAC molecules contain small-molecule warheads that bind to target proteins. Recently, oligonucleotide-warheaded PROTACs have emerged as a promising new tool to degrade DNA-binding proteins such as transcription factors. In this study, we applied an oligonucleotide-warheaded PROTAC technology to induce the degradation of signal transducer and activator of transcription 3 (STAT3), which is a hard-to-target protein. A double-stranded decoy oligonucleotide specific to STAT3 was conjugated to E3 binders (pomalidomide, VH032, and LCL161) to generate PROTAC molecules that recruited different E3 ubiquitin ligases cereblon (CRBN), von Hippel-Lindau (VHL), and inhibitor of apoptosis protein (IAP), respectively. One of the resulting PROTAC molecules, POM-STAT3, which recruits CRBN, potently induces STAT3 degradation. STAT3 degradation by POM-STAT3 was abolished by scrambling the oligonucleotide sequences of POM-STAT3 and by adding a double-stranded decoy oligonucleotide against STAT3 in a competitive manner, suggesting the significance of oligonucleotide sequences in STAT3 degradation. Moreover, POM-STAT3-induced STAT3 degradation was suppressed by the CRBN binder thalidomide, proteasome inhibitor bortezomib, E1 inhibitor MLN7243, and siRNA-mediated depletion of CRBN, indicating that STAT3 degradation is mediated by the ubiquitin-proteasome system, which involves CRBN as the responsible E3 ubiquitin ligase. Consistent with STAT3 degradation, NCI-H2087 cell viability was severely reduced following POM-STAT3 treatment. Thus, POM-STAT3 is a STAT3 degrader that potentially has cytocidal activity against cancer cells that are highly dependent on STAT3 signaling, which implies that inducing protein degradation by decoy oligonucleotide-warheaded PROTAC molecules could be harnessed to be therapeutic against oncogenic transcription factors.

Abstract
Proteolysis-targeting chimeras (PROTACs) have attracted attention as a chemical method of protein knockdown via the ubiquitin-proteasome system. Some oligonucleotide-based PROTACs have recently been developed for disease-related proteins that do not have optimal small-molecule ligands such as transcription factors. We have previously developed the PROTAC LCL-ER(dec), which uses a decoy oligonucleotide as a target ligand for estrogen receptor α (ERα) as a model transcription factor. However, LCL-ER(dec) has a low intracellular stability because it comprises natural double-stranded DNA sequences. In the present study, we developed PROTACs containing chemically modified decoys to address this issue. Specifically, we introduced phosphorothioate modifications and hairpin structures into LCL-ER(dec). Among the newly designed PROTACs, LCL-ER(dec)-H46, with a T4 loop structure at the end of the decoy, showed long-term ERα degradation activity while acquiring enzyme tolerance. These findings suggest that the introduction of hairpin structures is a useful modification of oligonucleotides in decoy oligonucleotide-based PROTACs.

Abstract
Targeted protein degradation (TPD), using chimeric molecules such as proteolysis-targeting chimeras (PROTACs), has attracted attention as a strategy for selective degradation of intracellular proteins by hijacking the ubiquitin-proteasome system (UPS). However, it is often difficult to develop such degraders due to the absence of appropriate ligands for target proteins. In targeting proteins for degradation, the application of nucleic acid aptamers is considered to be effective because these can be explored using systematic evolution of ligand by exponential enrichment (SELEX) methods. In this study, we constructed chimeric molecules in which nucleic acid aptamers capable of binding to the estrogen receptor α (ERα) and E3 ubiquitin ligase ligands were linked via a linker. ERα aptamer-based PROTACs were found to degrade ERα via the UPS. These findings represent the development of novel aptamer-based PROTACs that target intracellular proteins and are potentially applicable to other proteins.

Abstract
Developing highly active proteolysis-targeting chimeras (PROTACs) requires investigating a variety of ubiquitin ligase (E3 ligase) ligands and linker structures as well as their lengths. In this study, we developed a solid-phase synthesis method that affords PROTAC design diversity. We expanded the E3 ligand range to include Von Hippel-Lindau (VHL) and inhibitor of apoptosis protein (IAP) ligands because only the cereblon (CRBN) ligand thalidomide and its derivatives have been investigated for solid-phase synthesis of PROTACs. Moreover, we examined the suitability of a polyethylene glycol (PEG) rather than an alkyl linker used in our previous study for synthesizing PROTACs. Facile and rapid solid-phase synthesis methods using the above E3 ligands for developing PROTACs targeting bromodomain-containing protein 4 (BRD4) were accomplished. Western blotting analysis revealed that minor differences in the E3 ligand and linker type significantly affected the activity of the synthesized PROTACs. Our solid-phase PROTAC synthesis methods enable rapid synthesis of multiple PROTACs with various combinations of ligands for the protein-of-interest and E3 ligands and linkers that connect these ligands.

Abstract
The Japanese Pharmacopoeia (JP) is an official normative publication for establishing the authenticity and properties and maintaining the quality of pharmaceutical products in Japan. The JP is revised every five years and partially revised in order to respond to the progress of science and technology, the demand for medical care, and international harmonization. Thus, "Internationalization of the JP" is one of the most important issues to address for the revision of the JP, which is also referred to the basic principles for the preparation of the JP 19th edition. For instance, the incorporation of the test methods that have been used in other pharmacopeias, such as the European Pharmacopoeia (EP) and the United States Pharmacopeia (USP), into the JP is one of promising approaches. From this perspective, we have recently reported changes in test methods, establishment of a quantitative test method for the JP-listed clonidine hydrochloride as well as lorazepam from using a potentiometric titration method to using HPLC method. As our ongoing study to change test methods for internationalization, we selected sodium cromoglicate and trihexyphenidyl hydrochloride. Each pharmaceutical product is analyzed using a potentiometric titration method as listed in the 18th JP; however, both the EP and the USP use HPLC method for quantitative analysis of these drugs. In this study, we synthesized the related impurities of sodium cromoglicate and trihexyphenidyl hydrochloride listed in the EP and determined their purities using quantitative NMR. The separation conditions of these compounds were examined using HPLC and simultaneous analyses were performed.

Abstract
Understanding the characteristics of crystal polymorphism of active pharmaceutical ingredients and analyzing them with high sensitivity is important for quality of drug products, appropriate characterization strategies, and appropriate screening and selection processes. However, there are few methods to measure intra- and intermolecular correlations in crystals other than X-ray crystallography, for which it is sometimes difficult to obtain suitable single crystals. Recently, solid-state NMR has been recognized as a straightforward method for measuring molecular correlations. In this study, we selected ranitidine hydrochloride, which is known to exist in two forms, 1 and 2, as the model drug and investigated each form using solid-state NMR. In conducting the analysis, rotating the sample tube, which had a 1-mm inner diameter, increased the solid-state NMR resolution at 70 kHz. The 1H-14N dipolar-based heteronuclear multiple quantum coherence (D-HMQC) analysis revealed the intermolecular correlation of Form 1 between the N atom of the nitro group and a proton of the furan moiety, which were closer than those of the intramolecular correlation reported using single X-ray crystal analysis. Thus, 1H-14N D-HMQC analysis could be useful for characterizing intermolecular interaction in ranitidine hydrochloride crystals. In addition, we reassigned the 13C solid-state NMR signals of ranitidine hydrochloride according to the liquid-state and multiple solid-state NMR experiments.

Abstract
Stimulator of Interferon Genes (STING) is a type of endoplasmic reticulum (ER)-membrane receptor. STING is activated by a ligand binding, which leads to an enhancement of the immune-system response. Therefore, a STING ligand can be used to regulate the immune system in therapeutic strategies. However, the natural (or native) STING ligand, cyclic-di-nucleotide (CDN), is unsuitable for pharmaceutical use because of its susceptibility to degradation by enzymes and its low cell-membrane permeability. In this study, we designed and synthesized CDN derivatives by replacing the sugar-phosphodiester moiety, which is responsible for various problems of natural CDNs, with an amine skeleton. As a result, we identified novel STING ligands that activate or inhibit STING. The cyclic ligand 7, with a cyclic amine structure containing two guanines, was found to have agonistic activity, whereas the linear ligand 12 showed antagonistic activity. In addition, these synthetic ligands were more chemically stable than the natural ligands.

Abstract
Ciclesonide (Cic) is approved as an inhalant for asthma and was clinically tested as a candidate therapy for coronavirus disease 2019 (COVID-19). Its active metabolite Cic2 was recently reported to suppress genomic RNA replication of severe acute respiratory syndrome coronavirus 2. In this study, we designed and synthesized a set of ciclesonide-acetal (Cic-acetal) derivatives. Among designated compounds, some Cic-acetal derivatives with a linear alkyl chain exhibited strong viral copy-number reduction activities compared with Cic2. These compounds might serve as lead compounds for developing novel anti-COVID-19 agents.

Abstract
Targeted protein degradation using chimeric small molecules, such as proteolysis-targeting chimeras (PROTACs) and specific and nongenetic inhibitors of apoptosis protein (IAP)-dependent protein erasers (SNIPERs), has attracted attention as a method for degrading intracellular target proteins via the ubiquitin-proteasome system (UPS). These chimeric molecules target a variety of proteins using small molecules that can bind to the proteins. However, it is difficult to develop such degraders in the absence of suitable small-molecule ligands for the target proteins, such as for transcription factors (TFs). Therefore, we constructed the chimeric molecule LCL-ER(dec), which consists of a decoy oligonucleotide that can bind to estrogen receptor α (ERα) and an IAP ligand, LCL161 (LCL), in a click reaction. LCL-ER(dec) was found to selectively degrade ERα via the UPS. These findings will be applicable to the development of other oligonucleotide-type degraders that target different TFs.

Abstract
Norgestomet is a synthetic progesterone derivative applied in veterinary medicine to control estrus and ovulation in cattle. Norgestomet has been widely used in the livestock industry to promote the synchronization of estrus in cattle and increase pregnancy rates. However, highly reproducible synthetic methods for Norgestomet have been rarely reported. Here, we described a method for the synthesis of Norgestomet and performed quantitative NMR analysis to determine the purity of the products. Moreover, the agonistic activity of the synthesized compounds against progesterone receptors (PRs) was evaluated using an alkaline phosphatase assay. We synthesized Norgestomet with 97.9% purity that exhibited agonistic activity against PR with EC50 values of 4.5 nM. We also synthesized the 17β-isomer of Norgestomet with 92.7% purity that did not exhibit any PR agonistic activity. The proposed synthetic route of Norgestomet can facilitate the assessment of residual Norgestomet in foods.

Abstract
Bacterial biofilms often cause medical complications and there has been a great deal of interest in the discovery of small-molecule agents that can inhibit the formation of biofilms. Among these agents, it has been reported that several d-amino acids, such as d-Leu, d-Trp, d-Tyr, and d-Met, exhibit weak inhibitory activity toward bacterial biofilm formation. In this study, we have screened a library of 332 non-proteinogenic amino acids for new biofilm inhibitory agents and discovered several compounds exhibiting biofilm-inhibitory activity against Gram-positive bacteria. In particular, H-DL-β-(3,4-dihydroxyphenyl)-dl-Ser-OH (253) showed potent activity against S. aureus, including methicillin-resistant S. aureus.

Abstract
N-Nitrosodimethylamine (NDMA) is a probable human carcinogen. This study investigated the root cause of the presence of NDMA in ranitidine hydrochloride. Forced thermal degradation studies of ranitidine hydrochloride and its inherent impurities (Imps. A, B, C, D, E, F, G, H, I, J, and K) listed in the European and United States Pharmacopeias revealed that in addition to ranitidine, Imps. A, C, D, E, H, and I produce NDMA at different rates in a solid or an oily liquid state. The rate of NDMA formation from amorphous Imps. A, C, and E was 100 times higher than that from crystalline ranitidine hydrochloride under forced degradation at 110 °C for 1 h. Surprisingly, crystalline Imp. H, bearing neither the N,N-dialkyl-2-nitroethene-1,1-diamine moiety nor a dimethylamino group, also generated NDMA in the solid state, while Imp. I, as an oily liquid, favorably produced NDMA at moderate temperatures (e.g., 50 °C). Therefore, strict control of the aforementioned specific impurities in ranitidine hydrochloride during manufacturing and storage allows appropriate control of NDMA in ranitidine and its pharmaceutical products. Understanding the pathways of the stability related NDMA formation enables improved control of the pharmaceuticals to mitigate this risk.

Abstract
The Japanese Pharmacopoeia (JP) is an official normative guide for maintaining the authenticity of properties and qualities of medicine in Japan. The JP is revised every 5 years, and partial amendments are made from time to time to keep abreast with progress in science and technology and international harmonization. We are conducting a related study on the elimination of toxic reagents from the JP. The elimination of toxic reagents is an important study in relation to the five pillars of the revision of the 18th JP, "Improvement in quality by proactively introducing the latest knowledge and technological advances". In addition, "Internationalization of the JP" is an important issue to be addressed during revision of the JP. Considering international harmonization of the JP, it is important to incorporate the test methods that have been used in other pharmacopoeia, such as the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP) in the JP. To achieve the above, herein, we selected clonidine hydrochloride, which is listed in the 17th JP. A potentiometric titration method is used as a quantitative method for clonidine hydrochloride in the 17th JP; in contrast, a HPLC method is utilized in the USP and the EP. In this study, we synthesized impurities of clonidine hydrochloride and determined their purities using quantitative NMR. In addition, the complete separation conditions of these compounds by HPLC were examined, and simultaneous analysis was performed.

Abstract
The Japanese Pharmacopoeia (JP) is an official normative publication that is referred to, for establishing the authenticity and properties and maintaining the quality of pharmaceutics in Japan. Partial amendments are periodically made to these guidelines to keep up with the progress of science and technology, and the international harmonization is revised every 5 years. Thus, "Internationalization of the JP" is one of the more important issues to address for the revision of the JP. For example, the incorporation of the test methods that have been used in other pharmacopeias, such as the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP), into the JP is a useful approach. In light of this, we have recently reported changes in test methods in the 17th JP, "Establishment of a quantitative test method for clonidine hydrochloride from using a potentiometric titration method to using HPLC". As a part of our ongoing research to change test methods for internationalization, we selected lorazepam. Lorazepam is analyzed using a potentiometric titration method as listed in the 17th JP; however, both the USP and EP use HPLC for quantitative analysis of this drug. In this study, we synthesized the related impurities of lorazepam listed in the USP and the EP and determined their purities using quantitative NMR. The separation conditions of these compounds, including lorazepam, were examined using HPLC and simultaneous analyses were performed. In addition, lorazepam extracted from the tablets was analyzed using conditions similar to those used for the analysis of the related impurities.

Abstract
Liver X receptors (LXRs) belong to the nuclear hormone receptor superfamily and function as ligand-dependent transcription factors that regulate cholesterol homeostasis, lipid homeostasis, and immune responses. LXR antagonists are promising treatments for hypercholesterolemia and diabetes. However, effective LXR antagonists and inhibitors are yet to be developed. Thus, we aimed to develop LXR degraders (proteolysis targeting chimeras PROTACs against LXR) as a complementary strategy to provide a similar effect to LXR inhibition. In this study, we report the development of GW3965-PEG5-VH032 (3), a PROTAC capable of effectively degrading LXRβ protein. Compound 3 induced the ubiquitin-proteasome system-dependent degradation of the LXRβ protein, which requires VHL E3 ligase. We hope that PROTACs targeting LXR proteins will become novel therapeutic agents for LXR-related diseases.

Abstract
Ciclesonide is an inhaled corticosteroid used to treat asthma and is currently undergoing clinical trials for treatment of coronavirus disease 2019 (COVID-19). An active metabolite of ciclesonide, Cic2, was recently reported to repress severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genomic RNA replication. Herein, we designed and synthesized a few types of ciclesonide analogues. Cic4 (bearing an azide group) and Cic6 (bearing a chloro group) potently decreased SARS-CoV-2 viral replication and had low cytotoxicity compared with Cic2 (bearing a hydroxy group). These compounds are promising as novel therapeutic agents for COVID-19 that show significant antiviral activity.

Abstract
Can current simulations quantitatively predict the stability of ribonucleic acids (RNAs)? In this research, we apply a free-energy perturbation simulation of RNAs containing inosine, a modified ribonucleic base, to the derivation of RNA nearest-neighbor parameters. A parameter set derived solely from 30 simulations was used to predict the free-energy difference of the RNA duplex with a mean unbiased error of 0.70 kcal/mol, which is a level of accuracy comparable to that obtained with parameters derived from 25 experiments. We further show that the error can be lowered to 0.60 kcal/mol by combining the simulation-derived free-energy differences with experimentally measured differences. This protocol can be used as a versatile method for deriving nearest-neighbor parameters of RNAs with various modified bases.

Abstract
The side effects of kwao keur dietary supplements (obtained from the tuberous root of Pueraria mirifica) have recently been reported by the Ministry of Health, Labour and Welfare, Japan. To control the quality of kwao keur products, its ingredients need to be maintained by characteristic marker compounds, such as miroestrol, deoxymiroestrol, and kwakhurin (KWA). In this study, we described the facile synthesis of KWA, a marker compound of P. mirifica. Our revised synthetic method produced KWA with shorter steps and higher yield than the reported method. Furthermore, the absolute purity of KWA was determined by quantitative NMR analysis for standardization as a reagent, and its purity was 92.62 ± 0.12%.

Abstract
Fusion genes resulting from chromosomal rearrangements are frequently found in a variety of cancer cells. Some of these are known to be driver oncogenes, such as BCR-ABL in chronic myelogenous leukemia (CML). The products of such fusion genes are abnormal proteins that are ordinarily degraded in cells by a mechanism known as protein quality control. This suggests that the degradation of BCR-ABL protein is suppressed in CML cells to ensure their proliferative activity. Here, we show that ubiquitin-specific protease 25 (USP25) suppresses the degradation of BCR-ABL protein in cells harboring Philadelphia chromosome (Ph). USP25 was found proximal to BCR-ABL protein in cells. Depletion of USP25 using shRNA-mediated gene silencing increased the ubiquitylated BCR-ABL, and reduced the level of BCR-ABL protein. Accordingly, BCR-ABL-mediated signaling and cell proliferation were suppressed in BCR-ABL-positive leukemia cells by the depletion of USP25. We further found that pharmacological inhibition of USP25 induced rapid degradation of BCR-ABL protein in Ph-positive leukemia cells, regardless of their sensitivity to tyrosine kinase inhibitors. These results indicate that USP25 is a novel target for inducing the degradation of oncogenic BCR-ABL protein in Ph-positive leukemia cells. This could be an effective approach to overcome resistance to kinase inhibitors.

Abstract
Targeted protein degradation using small chimeric molecules, such as proteolysis-targeting chimeras (PROTACs) and specific and nongenetic inhibitors of apoptosis protein [IAP]-dependent protein erasers (SNIPERs), is a promising technology in drug discovery. We recently developed a novel class of chimeric compounds that recruit the aryl hydrocarbon receptor (AhR) E3 ligase complex and induce the AhR-dependent degradation of target proteins. However, these chimeras contain a hydrophobic AhR E3 ligand, and thus, degrade target proteins even in cells that do not express AhR. In this study, we synthesized new compounds in which the AhR ligands were replaced with a hydrophobic adamantane moiety to investigate the mechanisms of AhR-independent degradation. Our results showed that the compounds, 2, 3, and 16 induced significant degradation of some target proteins in cells that do not express AhR, similar to the chimeras containing AhR ligands. However, in cells expressing AhR, 2, 3, and 16 did not induce the degradation of other target proteins, in contrast with their response to chimeras containing AhR ligands. Overall, it was suggested that target proteins susceptible to the hydrophobic tagging system are degraded by chimeras containing hydrophobic AhR ligands even without AhR.

Here, we expand the repertoire of E3 ligases capable of ubiquitylating target proteins using this system. By incorporating β-naphthoflavone (β-NF) as a ligand, we developed a novel class of chimeric molecules that recruit the arylhydrocarbon receptor (AhR) E3 ligase complex. β-NF-ATRA, a chimeric degrader directed against cellular retinoic acid binding proteins (CRABPs), induced the AhR-dependent degradation of CRABP-1 and CRABP-2 via the ubiquitin-proteasome pathway. A similar compound ITE-ATRA, in which an alternative AhR ligand was used, also degraded CRABP proteins. Finally, we developed a chimeric compound β-NF-JQ1 that is directed against bromodomain-containing (BRD) proteins using β-NF as an AhR ligand. β-NF-JQ1 induced the interaction of AhR and BRD proteins and displayed effective anticancer activity that correlated with protein knockdown activity. These results demonstrate a novel class of chimeric degrader molecules based on the ability to bring a target protein and an AhR E3 ligase into close proximity.

Abstract
Abstract
Targeted protein degradation using chimeric small molecules is an emerging modality in drug discovery. These compounds termed proteolysis-targeting chimeras (PROTACs) and specific and nongenetic inhibitors of apoptosis protein [IAP]-dependent protein erasers (SNIPERs) contain two ligands connected with a linker: one ligand is specific for an E3 ubiquitin ligase, and the other ligand is specific for the target protein, and cross-link the E3 ligase and the target protein within the cell, thereby inducing the poly-ubiquitylation and proteasomal degradation of the target. Currently only a limited number of the E3 ligases, including IAPs, VHL and CRBN, can be recruited to the target proteins by this technology. Here, we expand the repertoire of E3 ligases capable of ubiquitylating target proteins using this system. By incorporating β-naphthoflavone (β-NF) as a ligand for E3 ubiquitin ligase, we developed a novel class of chimeric molecules that recruit the aryl-hydrocarbon receptor (AhR) E3 ligase complex. β-NF-ATRA, a chimeric degrader directed against cellular retinoic acid binding proteins (CRABPs), induced the AhR-dependent degradation of CRABP-1 and CRABP-2 via the ubiquitin-proteasome pathway. A similar compound ITE-ATRA, in which an alternative AhR ligand was used, also degraded CRABP proteins. We also developed a chimeric compound b-NF-JQ1 that is directed against bromodomain-containing (BRD) proteins using b-NF as an AhR ligand. β-NF-JQ1 induced the interaction of AhR and BRD proteins and displayed effective anticancer activity that correlated with protein knockdown activity. These results demonstrate a novel class of chimeric degrader molecules based on the ability to recruit AhR E3 ligase to the target proteins.

Abstract
Fluorescence labeling of the target molecules using a small molecule-based probe is superior than a method using genetically expressed green fluorescence protein (GFP) in terms of convenience in its preparation and functionalization. Fluorophore-nitrilotriacetic acid (NTA) conjugates with several ester protecting groups were synthesized and evaluated for their cell membrane permeability by fluorescence microscopy analysis. One of the derivatives, acetoxymethyl (AM)-protected NTA conjugate is hydrolyzed, resulting in intracellular accumulation, thus providing localized fluorescence intensity in cells. This modification is expected as an effective method for converting a non-cell membrane permeable NTA-BODIPY conjugates to a cell membrane permeable derivatives.

Abstract
BACKGROUND Barrier dysfunction is an important feature of atopic dermatitis (AD) in which IL-4 and IL-13, signature type 2 cytokines, are involved. Periostin, a matricellular protein induced by IL-4 or IL-13, plays a crucial role in the onset of allergic skin inflammation, including barrier dysfunction. However, it remains elusive how periostin causes barrier dysfunction downstream of the IL-13 signal. METHODS We systematically identified periostin-dependent expression profile using DNA microarrays. We then investigated whether IL-24 downregulates filaggrin expression downstream of the IL-13 signals and whether IL-13-induced IL-24 expression and IL-24-induced downregulation of filaggrin expression are dependent on the JAK/STAT pathway. To build on the significance of in vitro findings, we investigated expression of IL-24 and activation of STAT3 in mite-treated mice and in AD patients. RESULTS We identified IL-24 as an IL-13-induced molecule in a periostin-dependent manner. Keratinocytes are the main IL-24-producing tissue-resident cells stimulated by IL-13 in a periostin-dependent manner via STAT6. IL-24 significantly downregulated filaggrin expression via STAT3, contributing to barrier dysfunction downstream of the IL-13/periostin pathway. Wild-type mite-treated mice showed significantly enhanced expression of IL-24 and activation of STAT3 in the epidermis, which disappeared in both STAT6-deficient and periostin-deficient mice, suggesting that these events are downstream of both STAT6 and periostin. Moreover, IL-24 expression was enhanced in the epidermis of skin tissues taken from AD patients. CONCLUSIONS The IL-13/periostin pathway induces IL-24 production in keratinocytes, playing an important role in barrier dysfunction in AD.

Abstract
Endothelin-1 (ET-1) is associated with skin diseases such as atopic dermatitis (AD) and psoriasis. ET-1 is enhanced in the skin of patients AD and psoriasis. In addition, plasma levels of ET-1 are elevated in AD and psoriasis. Although both AD and psoriasis are T-cell-mediated skin diseases, the association between ET-1 and the T-cell immune response has not been clarified. To evaluate the role of ET-1 in inflammatory skin disease, we sought to investigate the effects of ET-1 on the functions of dendritic cells (DCs) and subsequent immune responses. For this purpose, we immunohistochemically confirmed the upregulation of ET-1 in the epidermis of patients with AD or psoriasis. ET-1 directly induced phenotypic maturation of bone marrow-derived DCs (BMDCs). In addition, ET-1 augmented the production of several cytokines and allogeneic stimulatory capacity of BMDCs. Interestingly, ET-1-activated BMDCs primed T cells to produce Th1 and Th17 cytokines, but not Th2 cytokines. These findings indicate that ET-1 polarizes the DC-T-cell response toward Th17/1 differentiation and may augment the persistent course of inflammatory skin diseases.

Abstract
We developed a new approach for chemical ligation of oligonucleotides using the electrophilic phosphorothioester (EPT) group. A nucleophilic phosphorothioate group on oligonucleotides was converted into the EPT group by treatment with Sanger's reagent (1-fluoro-2,4-dinitrobenzene). EPT oligonucleotides can be isolated, stored frozen, and used for the ligation reaction. The reaction of the EPT oligonucleotide and an amino-modified oligonucleotide took place without any extra reagents at pH 7.0–8.0 at room temperature, and resulted in a ligation product with a phosphoramidate bond with a 39–85% yield. This method has potential uses in biotechnology and chemical biology.

Abstract
Acute myeloid leukemia (AML) is an aggressive malignancy with only a handful of therapeutic options. About 30% of AML patients harbor mutated FLT3 kinase, and thus, this cancer-driver has become a hotly pursued AML target. Herein we report a new class of FLT3 inhibitors, which potently inhibit the proliferation of acute myeloid leukemia (AML) cells at nanomolar concentrations.

Abstract
A cyclic dinucleotide riboswitch has been fused with a G-quadruplex motif to produce a conditional riboswitch-peroxidase-mimicking sensor that oxidizes both colorimetric and fluorogenic substrates in the presence of c-di-GMP. We find that signal-to-noise ratio could be improved by using a two-, not three-, floor split G-quadruplex for this conditional peroxidase-mimicking riboswitch.

Abstract
Various important cellular processes in bacteria are controlled by c-di-GMP, such as motility, biofilm formation and virulence factors production. C-di-GMP is synthesized from two molecules of GTP by diguanylate cyclases (DGCs) and its actions are terminated by EAL or HD-GYP domain phosphodiesterases (PDEs), which hydrolyze c-di-GMP to linear pGpG or GMP. Thus far the majority of efforts have been dedicated to the development of inhibitors of DGCs but not PDEs. This is probably because the old view was that inhibiting any c-di-GMP PDE would lead to biofilm formation, an undesirable phenotype. Recent data however suggest that some PDEs only change the localized (not global) concentration of c-di-GMP to increase bacterial virulence and do not affect biofilm formation. A challenge therefore is to be able to develop selective PDE inhibitors that inhibit virulence-associated PDEs but not inhibit PDEs that regulate bacterial biofilm formation. Using high throughput docking experiments to screen a library of 250 000 commercially available compounds against E. coli YahA (also called PdeL), a benzoisothiazolinone derivative was found to bind to the c-di-GMP binding site of YahA with favorable energetics. Paradoxically the in silico identified inhibitor (a benzoisothiazolinone derivative) did not inhibit the hydrolysis of c-di-GMP by YahA, the model PDE that was used in the docking, but instead inhibited RocR, which is a PDE from the opportunistic pathogen P. aeruginosa (PA). RocR promotes bacterial virulence but not biofilm dispersal, making it an ideal PDE to target for anti-virulence purposes. This newly identified RocR ligand displayed some selectivity and did not inhibit other P. aeruginosa PDEs, such as DipA, PvrR and PA4108. DipA, PvrR and PA4108 are key enzymes that reduce global c-di-GMP concentration and promote biofilm dispersal; therefore the identification of an inhibitor of a PA PDE, such as RocR, that does not inhibit major PDEs that modulate global c-di-GMP is an important step towards the development of selective c-di-GMP PDEs that could have interesting biomedical applications. The identified RocR ligand could also inhibit P. aeruginosa (PAO1) swarming but not swimming or biofilm formation. Rhamnolipid production was decreased, explaining the inhibition of swarming.
