Abstract
Janus kinases (JAKs), a kind of non-receptor tyrosine kinases, the function has been implicated in the regulation of cell proliferation, differentiation and apoptosis, immune, inflammatory response and malignancies. Among them, JAK1 represents an essential target for modulating cytokines involved in inflammation and immune function. Rheumatoid arthritis, atopic dermatitis, ulcerative colitis and psoriatic arthritis are areas where approved JAK1 drugs have been applied for the treatment. In the review, we provided a brief introduction to JAK1 inhibitors in market and clinical trials. The structures of high active JAK1 compounds (IC50 ≤ 0.1 nM) were highlighted, with primary focus on structure-activity relationship and selectivity. Moreover, the druggability processes of approved drugs and high active compounds were analyzed. In addition, the issues involved in JAK1 compounds clinical application as well as strategies to surmount these challenges, were discussed.

Abstract
Direct current (DC) electrosynthesis, which has undergone optimization over the past century, plays a pivotal role in a variety of industrial processes. Alternating current (AC) electrosynthesis, characterized by polarity reversal and periodic fluctuations, may be advantageous for multiple chemical reactions, but apparatus, principles, and application scenarios remain underdeveloped. In this work, we introduce a protocol for programmed AC (pAC) electrosynthesis that systematically adjusts currents, frequencies, and duty ratios. The application of representative pAC waveforms facilitates copper-catalyzed carbon-hydrogen bond cleavage in cross-coupling and difunctionalization reactions that exhibit suboptimal performance under DC and chemical oxidation conditions. Moreover, observing catalyst dynamic variation under diverse waveform applications provides mechanistic insight.

Abstract
Tofacitinib citrate (TOF) is a Janus kinase-3 inhibitor used for rheumatoid arthritis treatment. In this study, a molecularly imprinted polymer (MIP)-based sensor was produced using acrylamide as the functional monomer via photopolymerization technique for the electrochemical determination of TOF. This study is the first one to explain the electrochemical determination of TOF with a highly selective MIP-based sensor. The surface characterization of the MIP-based sensor was performed with scanning electron microscopy and energy-dispersive X-ray spectroscopy methods, and it was expanded with electrochemical characterization by cyclic voltammetry and electrochemical impedance spectroscopy (EIS) methods. TOF determination was performed using differential pulse voltammetry (DPV) and EIS methods in standard solution and spiked serum sample in the linear range between 1×10-11 M and 1×10-10 M. Very low limit of detection and limit of quantification values were found, confirming the sensitivity of the sensor. Recovery analysis with spiked serum and tablet samples verified the sensor's accuracy and applicability using DPV and EIS methods. The selectivity of the sensor was confirmed with imprinting factor and interference studies, and the sensor performance was controlled using non-imprinted polymer for comparison at every step.

Abstract
In this study, engineered imine reductases (IREDs) of IRED M5, originally from Actinoalloteichus hymeniacidonis, were obtained through structure-guided semi-rational design. By focusing on mutagenesis of the residues that directly interact with the ketone donor moiety, we identified two residues W234 and F260, playing essential roles in enhancing and reversing the stereoselectivity, respectively. Moreover, two completely enantio-complementary variants S241L/F260N (R-selectivity up to 99%) and I149D/W234I (S-selectivity up to 99%) were achieved. Both variants showed excellent stereoselectivity toward the tested substrates, offering valuable biocatalysts for synthesizing pyrrolidinamines. Its application was demonstrated in a short synthesis of the key intermediates of potential drug molecules leniolisib and JAK1 inhibitor 4, from cheap and commercially available pro-chiral N-Boc-piperidone 1 (2 and 3 steps, respectively).

Abstract
Rheumatoid arthritis is a chronic disease that seriously affects human health and quality of life, and it is one of the main causes of labor loss and disability. Many countries have listed rheumatoid arthritis as one of the national a key diseases to tackle. The pathogenesis of RA in humans is still unknown, and medical researchers believe that the pathogenesis of RA may be the result of a combination of genetic and environmental factors. RA is an incurable condition that can only be controlled and treated with conventional drugs. In this paper, the pathologic features and pathogenesis of RA were introduced, and the research progress of new anti-rheumatoid arthritis chemical drugs in recent years was reviewed.

Abstract
Pharmacological modulation of the Janus kinase (JAK) family has achieved clinically meaningful therapeutic outcomes for the treatment of inflammatory and hematopoietic diseases. Several JAK1 selective compounds are being investigated clinically to determine their anti-inflammatory potential. We used recombinant enzymes and primary human lymphocytes to assess the JAK1 specificity of itacitinib (INCB039110) and study inhibition of signal transducers and activators of transcription (STAT) signaling. Rodent models of arthritis and inflammatory bowel disease were subsequently explored to elucidate the efficacy of orally administered itacitinib on inflammatory pathogenesis. Itacitinib is a potent and selective JAK1 inhibitor when profiled against the other JAK family members. Upon oral administration in rodents, itacitinib achieved dose-dependent pharmacokinetic exposures that highly correlated with STAT3 pharmacodynamic pathway inhibition. Itacitinib ameliorated symptoms and pathology of established experimentally-induced arthritis in a dose-dependent manner. Furthermore, itacitinib effectively delayed disease onset, reduced symptom severity, and accelerated recovery in three distinct mouse models of inflammatory bowel disease. Low dose itacitinib administered via cannula directly into the colon was highly efficacious in TNBS-induced colitis but with minimal systemic drug exposure, suggesting localized JAK1 inhibition is sufficient for disease amelioration. Itacitinib treatment in an acute graft-versus-host disease (GvHD) model rapidly reduced inflammatory markers within lymphocytes and target tissue, resulting in a marked improvement in disease symptoms. This is the first manuscript describing itacitinib as a potent and selective JAK1 inhibitor with anti-inflammatory activity across multiple preclinical disease models. These data support the scientific rationale for ongoing clinical trials studying itacitinib in select GvHD patient populations.

Abstract
Aiming to develop potent JAK inhibitors, two series of 4-(1H-pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidine derivatives (8a-8p and 11a-11i) were designed and synthesized by coalescing various N-acylpiperidine motifs with baricitinib. The pharmacological results based on enzymatic and cellular assays identified the optimized compound 11e, which exerted over 90% inhibition rates against JAK1 and JAK2, and displayed the most compelling anti-inflammatory efficacy superior to baricitinib by inhibiting NO generation from LPS-induced RAW264.7 macrophages. Importantly, low cytotoxity of 11e was revealed by the IC50 value of 88.2 μM against normal RAW264.7 cells. The binding mode of 11e with JAK1 and JAK2 identified the essential structural bases in accord with SARs analysis. Furthermore, cellular morphology observation and western blot analysis disclosed the ability of 11e to relieve cells inflammatory damage by significantly down-regulating LPS-induced high expression of JAK1, JAK2, as well as pro cytokine IL-1β. Together, 11e was verified as a promising lead for JAK inhibitors for the treatment of inflammatory diseases.

Anti-rheumatoid arthritis effects in adjuvant-induced arthritis in rats and molecular docking studies of Polygonum orientale L. extracts. Immunol Lett 2018; 201:59-69. [PMID: 30471320 DOI: 10.1016/j.imlet.2018.11.009] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 11/08/2018] [Accepted: 11/18/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND PURPOSE Polygonum orientale L. (family: Polygonaceae), named Hongcao in China, has effects of dispelling wind and dampness, promoting blood circulation, and relieving pain. Our group has already studied and confirmed that POEa and POEe (ethyl acetate and ethyl ether extract of P. orientale, respectively) had anti-inflammatory and analgesic effects in early research, which was mainly relevant to the existence of flavonoids. According to the clinical application of P. orientale in traditional Chinese medicine, it has long been used for rheumatic arthralgia and rheumatoid arthritis. Therefore, our group further explored whether flavonoids of P. orientale have anti-rheumatoid arthritis effect and how does they play this role. METHODS Dried small pieces of the stems and leaves of P. orientale were decocted with water and partitioned successively to obtain POEa and POEe, respectively. The anti-rheumatoid arthritis effect of P. orientale was studied by using a Freund's complete adjuvant (FCA)-induced arthritis (AIA) in a rat model. The levels of PGE2, TNF-α, and IL-1β in serum of AIA rats were detected by enzyme linked immunosorbent assay (ELISA) to explore its mechanisms. In addition, we computationally studied the relationships between the 15 chemical components of POEa and POEe, and the currently focused 9 target proteins of rheumatoid arthritis by molecular docking. RESULTS Pharmacological experiments showed that POEa and POEe significantly ameliorate symptoms of rheumatoid arthritis via reducing paw swelling volume, arthritis score, and thymus and spleen indices, as well as increasing body weight in AIA rats. Simultaneously, the concentrations of PGE2, TNF-α, and IL-1β were significantly decreased by POEa and POEe. Histopathology revealed noticeable reduction in bone and cartilage, synovial hyperplasia, inflammatory cell infiltration, cartilage surface erosion, and joint degeneration by POEa and POEe treatment. In addition, the molecular docking studies showed that docking scores of 14 chemical compositions (including 12 flavonoids and 2 phenolic acids) of POEa and POEe with anti-rheumatoid arthritis protein targets were better than the complexed ligands of the anti-rheumatoid arthritis protein targets. Among them, six flavonoids in POEa and POEe had more docking protein targets (n ≥ 3). Five anti-rheumatoid arthritis targets including high-temperature requirement A1 protease (HtrA1), janus kinase 1 (JAK1), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (i-NOS), and prostaglandin E2 (PGE2) had better docking score compared with the complexed ligands. Moreover, most of the chemical components in POEa and POEe showed strong interaction with HtrA1. CONCLUSIONS The flavonoids of P. orientale have anti-rheumatoid arthritis effect. In addition, the molecular docking results indicate that quercetin, catechol, orientin, and other six flavonoids may be closely related to HtrA1, JAK1, COX-2, i-NOS, and PGE2 protein target receptors. It suggests that these chemical compositions form strong protein-ligand complexes with these protein targets, especially HtrA1 to exert anti-rheumatoid arthritis. Further experimental studies show that mechanisms of anti-rheumatoid arthritis effects may also be relevant to inhibit the levels of PGE2, TNF-α, and IL-1β in serum. Therefore, our group can further explore the possible active ingredients and mechanisms of the anti-rheumatoid arthritis effects of flavonoids, and focus on the inhibition of the expression of inflammatory factors and the TGF-β1/Smad signaling pathway associated with HtrA1 protein target receptors, which can provide a direction and powerful reference for the action mechanism and drug research of anti-rheumatoid arthritis of flavonoids in P. orientale.
