A small-molecule natural product, euodenine A (1), was identified as an agonist of the human TLR4 receptor. Euodenine A was isolated from the leaves of Euodia asteridula (Rutaceae) found in Papua New Guinea and has an unusual U-shaped structure. It was synthesized along with a series of analogues that exhibit potent and selective agonism of the TLR4 receptor. SAR development around the cyclobutane ring resulted in a 10-fold increase in potency. The natural product demonstrated an extracellular site of action, which requires the extracellular domain of TLR4 to stimulate a NF-kappaB reporter response. 1 is a human-selective agonist that is CD14-independent, and it requires both TLR4 and MD-2 for full efficacy. Testing for immunomodulation in PBMC cells shows the induction of the cytokines IL-8, IL-10, TNF-alpha, and IL-12p40 as well as suppression of IL-5 from activated PBMCs, indicating that compounds like 1 could modulate the Th2 immune response without causing lung damage.

Activated monocytes and macrophages have been postulated to play an important role in the pathogenesis of alcoholic liver disease (ALD). Monocyte activation can be documented by measurement of neopterin, adhesion cell molecules, and certain proinflammatory cytokines and chemokines. We first became interested in the role of monocytes and monocyte-derived cytokines in ALD in relation to altered zinc metabolism that occurs regularly in ALD. Patients with ALD have hypozincemia, which responds poorly to oral zinc supplementation. We have shown that in ALD monocytes make a low-molecular-weight substance that, when injected into rabbits, causes prominent hypozincemia. Subsequently, multiple cytokines [especially tumor necrosis factor (TNF) and interleukin (IL)-8] have been shown to be overproduced by monocytes in ALD. We initially showed that monocytes in ALD spontaneously produce TNF and overproduce TNF in response to a lipopolysaccharide (LPS) stimulus, and this could be attenuated by antioxidants in vitro and in vivo. Alterations in the endotoxin-binding protein LPS-binding protein, in CD14, and in the endotoxin receptor Toll-like receptor 4 all may play roles in enhanced proinflammatory cytokine signaling in ALD. Moreover, several groups have documented increased TNF receptor density in monocytes in ALD. Inadequate negative regulation of TNF occurs at multiple levels in ALD. This includes decreased monocyte production of the important antiinflammatory cytokine IL-10 and blunted response to the antiinflammatory properties of adenosine. Finally, generation of reactive oxygen species (which occurs during alcohol metabolism) and products of lipid peroxidation induce production of cytokines, such as TNF and IL-8. In conclusion, there are multiple overlapping potential mechanisms for enhanced proinflammatory cytokine production by monocytes in ALD. We postulate that activation of monocytes and macrophages with subsequent proinflammatory cytokine production plays an important role in certain metabolic complications of ALD and is a component of the liver injury of ALD.

There is considerable interest in discovering drugs with the potential to protect inner ear hair cells (HCs) from damage. One means of discovery is to screen compound libraries. Excellent screening protocols have been developed employing cell lines derived from the cochlea and zebrafish larvae. However, these do not address the differentiated mammalian hair cell. We have developed a screening method employing micro-explants of the mammalian organ of Corti (oC) to identify compounds with the ability to influence aminoglycoside-induced HC loss. The assay is based on short segments of the neonatal mouse oC, containing ~80 HCs which selectively express green fluorescent protein (GFP). This allows the screening of hundreds of potential protectants in an assay that includes both inner and outer HCs. This review article describes various screening methods, including the micro-explant assay. In addition, two micro-explant screening studies in which antioxidant and kinase inhibitor libraries were evaluated are reviewed. The results from these screens are related to current models of HC damage and protection.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 19771-63-2, you can also check out more blogs about19771-63-2

Reaction of phthalic acid with 2-methyl-4-N-phenylaminoquinoline under PPA condition resulted in the formation of 6-methyldibenzo[b, h][1,6]naphthyridines, whereas the same reaction with 2,4-bis(N-phenylamino)quinoline resulted in the dimeric dibenzo[b, h][1,6]naphthyridines. A novel mechanism has been proposed to explain the formation of the unexpected product. Screening for the antibacterial activity against various pathogens, proved that the dimeric analogs showed a better antibacterial activity when compared to their monomeric analogs.

A series of transition state analogues of beta-secretases 1 and 2 (BACE1, 2) inhibitors containing fused-ring or biaryl moieties were designed computationally to probe the S2 pocket, synthesized, and tested for BACE1 and BACE2 inhibitory activity. It has been shown that unlike the biaryl analogs, the fused-ring moiety is successfully accommodated in the BACE1 binding site resulting in the ligands with excellent inhibitory activity. Ligand 5b reduced 65% of Abeta40 production in N2a cells stably transfected with Swedish human APP.

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine “pro-drug” L-2-oxothiazolidine-4-carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

Methotrexate (MTX) is the standard of care in the treatment of rheumatoid arthritis (RA), a common autoimmune disease that is characterized by chronic inflammation in the synovial membrane of joints. Unfortunately, MTX suffers from high discontinuation rates due to a large variability in efficacy and, in particular, adverse effects. As inflammation is associated with elevated levels of reactive oxygen species (ROS) like H2O2, we propose to improve treatment through site-selective delivery of MTX to inflammatory tissue by use of a H2O2 sensitive MTX prodrug. To establish proof proof-of-concept, two novel H2O2 sensitive, thiazolidinone-based MTX prodrugs were synthesized and evaluated for this purpose. MTX-gamma-thiazolidinone (MTX-gamma-TZ) exhibited the most promising properties ? good to high chemical and metabolic stability, excellent aqueous solubility, while being activated when subjected to patho-physiological concentrations of H2O2. In vivo, MTX-gamma-TZ exhibited comparable efficacy to MTX in a murine collagen type II-induced arthritis (CIA) model while treated mice showed indications of reduced toxicity as their body weight decreased less towards the end of the study, compared to the MTX-treated group.
