Antibacterial and anti-quorum sensing activities of a substituted thiazole derivative against methicillin-resistant Staphylococcus aureus and other multidrug-resistant bacteria

Management of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) is still challenging. We herein report the antibacterial and anti-quorum sensing (anti-QS) activities of 5-acetyl-4-methyl-2-(3-pyridyl) thiazole (AMPT) against MRSA and other multidrug-resistant bacteria. Minimum inhibitory concentrations (MICs) were determined by agar dilution method and bactericidal activity was assessed by a time-kill assay. The anti-QS activity was evaluated using Chromobacterium violaceum. The effect of AMPT on virulence factors production by MRSA and biofilm formation by MRSA, C. violaceum and Pseudomonas aeruginosa was also assessed. AMPT was superior to vancomycin and teichoplanin against MRSA isolates. MIC50/90 values of AMPT (2/4 mg/L) were 24 folds lower than the values for vancomycin (4/16 mg/L) and 2-fold lower than the values for teichoplanin (4/8 mg/L). Results of time-kill assay against two multidrug-resistant MRSA isolates revealed bactericidal effect of AMPT after 4 h of treatment, with no bacterial cells detected after 24 h. Remarkably, AMPT exhibited anti-QS activity against both C. violaceum and MRSA at subinhibitory concentrations. Moreover, AMPT reduced haemolysin and protease production by MRSA and inhibited biofilm formation by MRSA, C. violaceum and P. aeruginosa but had no dispersion effect on preformed ones. Furthermore, molecular docking analysis revealed promising interactions between AMPT and AgrA as well as SarA in S. aureus confirming the antivirulence and antibiofilm activities. Favourably, no significant cytotoxicity of AMPT was observed on murine macrophage cell line. Taken altogether, these results suggest that AMPT could be considered an interesting lead compound in the search for treatment of MRSA infections.

Macrooxazoles A-D, New 2,5-Disubstituted Oxazole-4-Carboxylic Acid Derivatives from the Plant Pathogenic Fungus Phoma macrostoma

In our ongoing search for new bioactive fungal metabolites, four previously undescribed oxazole carboxylic acid derivatives (1-4) for which we proposed the trivial names macrooxazoles A-D together with two known tetramic acids (5-6) were isolated from the plant pathogenic fungus Phoma macrostoma. Their structures were elucidated based on high-resolution mass spectrometry (HR-MS) and nuclear magnetic resonance (NMR) spectroscopy. The hitherto unclear structure of macrocidin Z (6) was also confirmed by its first total synthesis. The isolated compounds were evaluated for their antimicrobial activities against a panel of bacteria and fungi. Cytotoxic and anti-biofilm activities of the isolates are also reported herein. The new compound 3 exhibited weak-to-moderate antimicrobial activity as well as the known macrocidins 5 and 6. Only the mixture of compounds 2 and 4 (ratio 1:2) showed weak cytotoxic activity against the tested cancer cell lines with an IC50 of 23 mu g/mL. Moreover, the new compounds 2 and 3, as well as the known compounds 5 and 6, interfered with the biofilm formation of Staphylococcus aureus, inhibiting 65%, 75%, 79%, and 76% of biofilm at 250 mu g/mL, respectively. Compounds 5 and 6 also exhibited moderate activity against S. aureus preformed biofilm with the highest inhibition percentage of 75% and 73% at 250 mu g/mL, respectively.

Structure-based linker exploration: Discovery of 1-ethyl-1H-indole analogs as novel ATX inhibitors

Aiming to develop novel ATX inhibitors, an indole-3-carboxylic acid lead Indole-1 was identified through high-throughput screening (HTS) efforts. The Indole-1 analogs 1-7 was firstly prepared which exerted mild activity comparable to Indole-1 (740 nM) in ATX enzyme assay. Further structural modification to identify type IV ATX inhibitors was proceeded through derivatization of the indole-3-carboxylic acid group. Resultantly, compounds 8-17 containing acyl hydrazone linker displayed poor activity (over 3.49 mu M). Alternatively, replacing the acylhydrazone linker with urea counterpart by the amide bond reversal principle, the acquired compounds 18-22 achieved obvious improvements with submicromolar activities. Furthermore, with the aim to reducing cLogP, the thiazole ring of 18-22 was altered to the benzamide (23-32) with the urea linker unchanged. Remarkably, the benzamide derivative 24 with 4-hydroxy piperidine fragment was identified which exhibited prominent activity with IC50 value of 2.3 nM. Especially, dedicated molecular docking study was throughout the modification process which qualified 24 as optimal entity in accordance with the ATX inhibitory results.

Probing the mechanism of gelation and anion sensing capability of a thiazole based amide gelator: A case study

In priori design of Low Molecular weight Gelators (LMWGs) based on the molecular structure is a challenging task and requires the hierarchy knowledge from single molecule packing to a supramolecular assembly in gelator fibers. A simple strategy to select and probe the packing of a molecule from a crystalline state to a semi solid gel state was undertaken in a Thiazole based amide, undecaneamido thiazole (Thz-9). The novel approach to select the promising molecule with gelation property was made using Small Angle Neutron Scattering (SANS) and Small Angle X-ray Scattering (SAXS) analysis of solid samples. Based on the preliminary examination of SANS/SAXS studies Thz-9 molecule was selected and subjected to study the packing of molecule in crystalline to a gel state. The sol-gel transition and variation of the molecular diameter of the supramolecular assembly of Thz-9 molecules in the various states were established using temperature dependent SANS study. Efforts were also directed to establish the relationship between the packing of molecules in single crystal structure to packing in xerogel (dried gel) using Powder X-ray Diffraction (PXRD). A potential application of Thz-9 as a fluoride ion sensor with good selectivity and sensitivity was established.

New imidazo[2,1-b]thiazole-based aryl hydrazones: unravelling their synthesis and antiproliferative and apoptosis-inducing potential

Herein, we have designed and synthesized new imidazo[2,1-b]thiazole-based aryl hydrazones (9a-w) and evaluated their anti-proliferative potential against a panel of human cancer cell lines. Among the synthesized compounds, 9i and 9m elicited promising cytotoxicity against the breast cancer cell line MDA-MB-231 with IC50 values of 1.65 and 1.12 mu M, respectively. Cell cycle analysis revealed that 9i and 9m significantly arrest MDA-MB-231 cells in the G0/G1 phase. In addition, detailed biological studies such as annexin V-FITC/propidium iodide, DCFH-DA, JC-1 and DAPI staining assays revealed that 9i and 9m triggered apoptosis in MDA-MB-213 cells. Overall, the current work demonstrated the cytotoxicity and apoptosis-inducing potential of 9i and 9m in breast cancer cells and suggested that they could be explored as promising antiproliferative leads in the future.

Discovery of a Novel Series of Potent and Selective Alkynylthiazole-Derived PI3K gamma Inhibitors

Phosphoinositide 3-kinases (PI3Ks) are a family of enzymes that control a wide variety of cellular functions such as cell growth, proliferation, differentiation, motility, survival, and intracellular trafficking. PI3K gamma plays a critical role in mediating leukocyte chemotaxis as well as mast cell degranulation, making it a potentially interesting target for autoimmune and inflammatory diseases. We previously disclosed a novel series of PI3K gamma inhibitors derived from a benzothiazole core. The truncation of the benzothiazole core led to the discovery of a structurally diverse alkynyl thiazole series which displayed high PI3K gamma potency and subtype selectivity. Further medicinal chemistry optimization of the alkynyl thiazole series led to identification of compounds such as 14 and 32, highly potent, subtype selective, and CNS penetrant PI3K gamma inhibitors. Compound 14 showed robust inhibition of PI3K gamma mediated neutrophil migration in vivo.

Design, synthesis, biological evaluation, and docking study of novel dualacting thiazole-pyridiniums inhibiting acetylcholinesterase and beta-amyloid aggregation for Alzheimer’s disease

New compounds containing thiazole and pyridinium moieties were designed and synthesized. The potency of the synthesized compounds as selective inhibitors of acetylcholinesterase (AChE), and beta-amyloid aggregation (A beta) was evaluated. Compounds 7d and 7j showed the best AChE inhibitory activities at the submicromolar concentration range (IC50 values of 0.40 and 0.69 mu M, respectively). Most of the novel compounds showed moderate to low inhibition of butyrylcholinesterase (BChE), which is indicative of their selective inhibitory effects towards AChE. Kinetic studies using the most potent compounds 7d and 7j confirmed a mixed-type of AChE inhibition mechanism in accordance with the docking results, which shows their interactions with both catalytic active (CAS) and peripheral anionic (PAS) sites. The specific binding of 7a, 7j, and 7m to PAS domain of AChE was also confirmed experimentally. In addition, 7d and 7j were able to show beta-amyloid self-aggregation inhibitory effects (20.38 and 42.66% respectively) stronger than donepezil (14.70%) assayed at 10 mu M concentration. Moreover, compounds 7j and 7m were shown to be effective neuroprotective agents in H2O2-induced oxidative stress on PC12 cells almost similar to those observed for donepezil. The ability of 7j to pass blood-brain barrier was demonstrated using the PAMPA method. The results presented in this work provide useful information about designing novel anti-Alzheimer agents.
