Abd-Elsalam, Wessam H.;Saber, Mona M.;Abouelatta, Samar M. research published 《 Trehalosomes: Colon targeting trehalose-based green nanocarriers for the maintenance of remission in inflammatory bowel diseases》, the research content is summarized as follows. The use of non-steroidal anti-inflammatory drugs (NSAIDs) in inflammatory bowel diseases (IBDs) are contradictory between their beneficial effect in alleviating inflammation, and injurious outcomes in aggravating the symptoms of colitis. The study aimed to formulate trehalosomes (THs); innovative green trehalose-based nanocarriers, to alleviate the inflammation symptoms that might be provoked by NSAIDs in IBDs; as trehalose was proved to lighten the inflammation and the oxidative stress response, besides its resistance to the acidic conditions that rises its potentiality as a means for colon targeting. THs were fabricated using L-α-phosphatidylcholine (PL), trehalose, and transcutol, in a single step circumventing the incorporation of any organic solvent and loaded with Tenoxicam (TXM) as a model anti-inflammatory medication. A full 23 factorial design, using Design-Expert software, was established to optimize the formulation variables. The optimized formulation composed of trehalose: PL at a weight ratio of 1:1, 377.72 mg transcutol, and sonicated for 4 min, possessed a spherical shape with a size of 268.61 nm and EE% of 97.83% and released 70.22% of its drug content over 24 h. The supreme protective action of TXM loaded THs compared to TXM suspension and drug-free THs was revealed by the suppression of the inflammatory biomarkers and the improved histopathol. of the colonic tissue in male New Zealand rabbits. IL-1ss, IL-6, and TNF-alpha levels were notably dampened with TXM loaded THs, and oxidative stress markers, measured as GSH and MDA, were significantly altered. The study indicates the successful role of green THs in colon targeting and its anti-inflammatory characteristics in protecting against possible NSAIDs-driven exacerbation of colitis.

Abdullaha, Mohd;Ali, Mehboob;Kour, Dilpreet;Mudududdla, Ramesh;Khajuria, Parul;Kumar, Ajay;Bharate, Sandip B. research published 《 Tetramethoxystilbene Inhibits NLRP3 Inflammasome Assembly via Blocking the Oligomerization of Apoptosis-Associated Speck-like Protein Containing Caspase Recruitment Domain: In Vitro and In Vivo Evaluation》, the research content is summarized as follows. Nucleotide-binding domain leucine-rich repeat family pyrin domain containing 3 (NLRP3) inflammasome complex regulates the caspase-1 activity and subsequent processing of interleukin-1β (IL-1β). Various inflammatory diseases involve the activation of inflammasome complexes; thus, the intervention in complex formation via small mols. offers a new therapeutic opportunity. The structure-guided design and synthesis of a series of methoxystilbenes and methoxy-2-phenylnaphthalenes identified new inhibitors of NLRP3 inflammasome complex. The tetramethoxystilbene 4o and trimethoxy 2-phenylnaphthalene 1t inhibit the release of a mature form of IL-1β in J774A.1 cells with IC50 values of 1.39 and 2.07μM, resp. Mechanistic investigation revealed that tetramethoxystilbene 4o blocks the oligomerization of apoptosis-associated speck-like protein (ASC), which is the vital step in the formation of NLRP3 inflammasome assembly, thus preventing the activation of caspase-1 and the IL-1β release. Treatment of LPS+ATP challenged mice with 20 mg/kg of 4o significantly suppressed the levels of IL-1β. The data presented herein warrant further investigation of methoxystilbenes in disease-specific models of inflammatory diseases.

Ackun-Farmmer, Marian A.;Soto, Celia A.;Lesch, Maggie L.;Byun, Daniel;Yang, Lila;Calvi, Laura M.;Benoit, Danielle S. W.;Frisch, Benjamin J. research published 《 Reduction of leukemic burden via bone-targeted nanoparticle delivery of an inhibitor of C-chemokine (C-C motif) ligand 3 (CCL3) signaling》, the research content is summarized as follows. Leukemias are challenging diseases to treat due, in part, to interactions between leukemia cells and the bone marrow microenvironment (BMME) that contribute significantly to disease progression. Studies have shown that leukemic cells secrete C-chemokine (C-C motif) ligand 3 (CCL3), to disrupt the BMME resulting in loss of hematopoiesis and support of leukemic cell survival and proliferation. In this study, a murine model of blast crisis chronic myelogenous leukemia (bcCML) that expresses the translocation products BCR/ABL and Nup98/HoxA9 was used to determine the role of CCL3 in BMME regulation. Leukemic cells derived from CCL3^-/- mice were shown to minimally engraft in a normal BMME, thereby demonstrating that CCL3 signaling was necessary to recapitulate bcCML disease. Further anal. showed disruption in hematopoiesis within the BMME in the bcCML model. To rescue the altered BMME, therapeutic inhibition of CCL3 signaling was investigated using bone-targeted nanoparticles (NP) to deliver Maraviroc, an inhibitor of C-C chemokine receptor type 5 (CCR5), a CCL3 receptor. NP-mediated Maraviroc delivery partially restored the BMME, significantly reduced leukemic burden, and improved survival. Overall, our results demonstrate that inhibiting CCL3 via CCR5 antagonism is a potential therapeutic approach to restore normal hematopoiesis as well as reduce leukemic burden within the BMME.

The ERCC1-XPF heterodimer is a 5′-3′ structure-specific endonuclease, which plays an essential role in several DNA repair pathways in mammalian cells. ERCC1-XPF is primarily involved in the repair of chem. induced helix-distorting and bulky DNA lesions, such as cyclobutane pyrimidine dimers (CPDs), and DNA interstrand cross-links. Inhibition of ERCC1-XPF has been shown to potentiate cytotoxicity of platinum-based drugs and cyclophosphamide in cancer cells.

Author is Moutzouri, Pinelopi; Kiraly, Peter; Phillips, Andrew R.; Coombes, Steven R.; Nilsson, Mathias; Morris, Gareth A..

A new NMR experiment (Destruction of Interfering Satellites by Perfect Echo Low-pass filtration, DISPEL) is introduced that facilitates the anal. of low-level components in high dynamic range mixtures by suppressing one-bond 13C satellite signals in 1H spectra. Since the natural abundance of 13C is around 1.1%, these satellites appear at 0.54% of the intensity of a parent peak, mimicking and often masking impurity signals. The new experiment suppresses one-bond 13C satellite signals, with high efficiency, at negligible cost in signal-to-noise ratio, and over a wide range of one-bond coupling constants, without the need for broadband 13C decoupling.

Author is Bhandare, Richie R.; Canney, Daniel J..

Lead lactone-based ligands with modest affinity for muscarinic receptors were modified based on structure-activity relationship data in the literature to provide a new series of 5-substituted 4,5-dihydro-2(3H)-furanones. The modifications included the addition of various nitrogen-containing heterocycles attached to substituted and unsubstituted aromatic rings. The target compounds, e.g. I, were synthesized in modest yields and evaluated in preliminary muscarinic binding assays. A lactone-based ligand containing a diphenylmethylpiperazine moiety was identified as a nonselective muscarinic ligand with IC50 of 340 nM. The design of future ligands will be based, in part, on structure-activity data reported herein.
