Human epithelial 15-lipoxygenase-2 (h15-LOX-2, ALOX15B) is expressed in many tissues and has been implicated in atherosclerosis, cystic fibrosis and ferroptosis. However, there are few reported potent/selective inhibitors that are active ex vivo. In the current work, we report newly discovered mols. that are more potent and structurally distinct from our previous inhibitors, MLS000545091 and MLS000536924 (Jameson et al, PLoS One, 2014, 9, e104094), in that they contain a central imidazole ring, which is substituted at the 1-position with a Ph moiety and with a benzylthio moiety at the 2-position. The initial three mols. were mixed-type, non-reductive inhibitors, with IC50 values of 0.34 ± 0.05 μM for MLS000327069, 0.53 ± 0.04 μM for MLS000327186 and 0.87 ± 0.06 μM for MLS000327206 and greater than 50-fold selectivity vs. h5-LOX, h12-LOX, h15-LOX-1, COX-1 and COX-2. A small set of focused analogs was synthesized to demonstrate the validity of the hits. In addition, a binding model was developed for the three imidazole inhibitors based on computational docking and a co-structure of h15-LOX-2 with MLS000536924. Hydrogen/deuterium exchange (HDX) results indicate a similar binding mode between MLS000536924 and MLS000327069, however, the latter restricts protein motion of helix-α2 more, consistent with its greater potency. Given these results, we designed, docked, and synthesized novel inhibitors of the imidazole scaffold and confirmed our binding mode hypothesis. Importantly, four of the five inhibitors mentioned above are active in an h15-LOX-2/HEK293 cell assay and thus they could be important tool compounds in gaining a better understanding of h15-LOX-2′s role in human biol. As such, a suite of similar pharmacophores that target h15-LOX-2 both in vitro and ex vivo are presented in the hope of developing them as therapeutic agents.

Derivatives of natural allylpolyalkoxybenzenes conjugated to triphenylphosphonium (TPP) cations by aliphatic linkers of three, six, seven, and eight atoms were synthesized to examine the role of the polyalkoxybenzene pharmacophore, TPP fragment, and linker length in antiproliferative activities. The key synthetic procedures included (i) hydroboration-oxidation of apiol, dillapiol, myristicin, and allyltetramethoxybenzene; (ii) acylation of polyalkoxybenzyl alcs. or amines; and (iii) condensation of polyalkoxybenzaldehydes followed by hydrogenation and cyclopropyl-homoallyl rearrangement. The targeted TPP conjugates as well as the starting allylbenzenes, the corresponding alkylpolyalkoxybenzenes, and the resp. alkyl-TPP salts were evaluated for cytotoxicity in a panel of human cancer cell lines using MTT and Click-iT-EdU assays and in a sea urchin embryo model. The linker of three carbon atoms was identified as favorable for selective cancer cell growth inhibition. Although the propyl-TPP salt was cytotoxic at low micromolar concentrations, the introduction of a polyalkoxybenzene moiety significantly potentiated inhibition of both cell growth and de novo DNA synthesis in several human cancer cell lines, HST-116 colon cancer, A375 melanoma, PC-3 prostate cancer, and T-47D breast carcinoma cells, while it failed to produce any developmental abnormalities in the sea urchin embryos.

D-Serine is a coagonist of the N-Me D-aspartate (NMDA) receptor, a key excitatory neurotransmitter receptor. In the brain, D-serine is synthesized from its L-isomer by serine racemase and is metabolized by the D-amino acid oxidase (DAO, DAAO). Many studies have linked decreased D-serine concentration and/or increased DAO expression and enzyme activity to NMDA dysfunction and schizophrenia. Thus, it is feasible to employ DAO inhibitors for the treatment of schizophrenia and other indications. Powered by the Schrödinger computational modeling platform, we initiated a research program to identify novel DAO inhibitors with the best-in-class properties. The program execution leveraged an hDAO FEP+ model to prospectively predict compound potency. A new class of DAO inhibitors with desirable properties has been discovered from this endeavor. Our modeling technol. on this program has not only enhanced the efficiency of structure-activity relationship development but also helped to identify a previously unexplored subpocket for further optimization.

Tang, Kai-Wei;Hsu, Wen-Li;Chen, Cheng-Ru;Tsai, Ming-Hsien;Yen, Chia-Jung;Tseng, Chih-Hua research published 《 Discovery of triazolyl thalidomide derivatives as anti-fibrosis agents》, the research content is summarized as follows. Fibrosis with excessive accumulation of extracellular matrix (ECM) often causes progressive organ dysfunction and results in many inflammatory and metabolic diseases, including systemic sclerosis, pulmonary fibrosis, advanced liver disease and advanced kidney disease. The store-operated calcium entry (SOCE) pathway and the related signaling pathway were both found to be the important routes for fibrogenesis. Our aim in this study was to discover novel compounds to inhibit fibrogenesis. A number of triazolyl thalidomide derivatives were synthesized and evaluated for their anti-fibrosis activities. Compounds inhibited intracellular Ca²⁺ activation and showed no cytotoxicity.

The in silico study indicated that compound I, with the appropriate lipophilic carbon chain and carboxylic acid, showed a good drug-likeness model score. Conclusively, the SOCE inhibitor, compound I, is used as a promising lead compound for the development of a new treatment for fibrosis.

Tang, Qun;Xie, Yu;Liu, Yongpeng;Zheng, Lifang research published 《 Synthesis of mitochondria-targeted menadione cation derivatives: Inhibiting mitochondrial thioredoxin reductase (TrxR2) and inducing apoptosis in MGC-803 cells》, the research content is summarized as follows. Menadione (VK3) is used as a powerful inducer of cellular reactive oxygen species (ROS) for many years and displays high anti-cancer activities in vivo. Recently, the development of mitochondria-targeted drugs has been more and more appreciated. Here, thirteen derivatives of VK3, I [R¹ = H, Me, MeO, R² = pyridinium, quinolinium, triphenylphosphonium, n = 9, 6, 4], were synthesized, which could localize in mitochondria by the triphenylphosphonium (TPP) cation or the nitrogen-based cation. The results of cytotoxicity from six human cancer cell lines showed that the targeted compounds I displayed higher activity than VK3 with the average IC₅₀ value around 1μM. The results of cytotoxicity indicated that the substituents on C-2, the linear alkyl chains on C-3 and the cation moiety all could affect the cytotoxicity. The mechanistic studies showed that five representative compounds, I [R¹ = Me, R² = triphenylphosphonium, n = 9; R¹ = MeO, R² = triphenylphosphonium, n = 9; R¹ = Me, R² = pyridinium, n = 9; R¹ = Me, R² = quinolinium, n = 9; R¹ = Me, R² = triphenylphosphonium, n = 4], could localize in cellular mitochondria, elicit ROS burst and collapse mitochondrial membrane potential (ΔΨ_m), leading to cytochrome C release and apoptosis in MGC-803 cells. Particularly, they could obviously inhibit mitochondrial thioredoxin reductase TrxR2 expression, thus leading to aggravate cellular oxidative stress.
