Toward N,P-Doped pi-Extended PAHs: A One-Pot Synthesis to Diannulated 1,4,2-Diazaphospholium Triflate Salts

A novel method for the one-pot synthesis of diannulated 1,4,2-diazaphospholium triflate salts by a Me3SiOTf-mediated self-condensation of dichlorophosphaneyl aza-(poly)cyclic aromatic hydrocarbons (aza-(P)AHs; namely, pyridine, quinoline, phenanthridine, and benzo[d]thiazole) is reported. The diannulated 1,4,2-diazaphospholium triflate salts are characterized by multi-nuclear NMR spectroscopy, X-ray analysis, as well as their calculated NICS values, underlining their aromatic character. Quantum mechanical calculations shed light on the intermolecular reaction mechanism. Follow up chemistry, such as the halogenation reaction with XeF2 or SO2Cl2 with the dipyridinium derivative selectively yields the respective dihalo-sigma(4),lambda(5)- and tetrahalo-sigma(5),lambda(6)-diazaphospholium triflate salts. The dihalo-sigma(4),lambda(5)-diazaphospholium triflate salt serves well as a surrogate for the introduction of the cationic 2-(1,2′-bipyridin)-1-iumyl ligand (1,2′-bipyl), the monocationic structural isomer of the prototypical 2,2′-bipyridine ligand (2,2′-bipy).

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 55981-09-4 help many people in the next few years. Formula: C12H9N3O5S.

Deciphering potential inhibitors targeting THI4 of Fusarium solani sp. to combat fungal keratitis: An integrative computational approach

Mycotic keratitis is a fungal infection of corneal epithelium. It is more common in tropical and subtropical countries and is one of the leading causes of blindness. Many of the antifungal drugs have been less effective in treating this condition and certain drugs which are efficient and yet limited in use due to its extreme side effects. Hence, in this study an attempt is made to identify potential and least toxic antifungal inhibitors that targets thiamine thiazole synthase, a novel target for suppressing Fusarium solani subsp.pisi (Nectria haematococca MPVI) infections, to combat mycotic keratitis. Integrative computational approaches involving model refinement, molecular dynamics simulation and High throughput virtual screening (HTVS) were applied through integrative multi precision mode in order to identify potential inhibitors. Moreover, machine learning approach was also implemented to prioritize potential inhibitors that are ophthalmic adaptive, as well as antifungal molecule. From the NCI and Maybridge datasets, for HTVS only 209,872 compounds that surpassed ligand property filtration were considered, which resulted in 209 compounds after XP docking. Among the top 5 compounds from XP docking, on cumulative analysis only 2-(1-hydroxyethyl)-1,3-thiazole-4-carboxamide was prioritized as the most potential hit, as it showed higher order of significance in terms of binding affinity, structural stability and therapeutic relevance for the treatment of Mycotic keratitis. Thus, widening the scope for novel antifungal therapy in ophthalmic infections.

Synthesis, application and AIE properties of novel fluorescent tetraoxocalix[2]arene[2]triazine: The detection of a hazardous anion, cyanate

A highly effective, new heterocalixarene fluorescent receptor comprised of 2-(2-aminophenyl)benzothiazole and tetraoxacalix[2]arene[2]triazine was designed and synthesized by one-step reaction. The sensor candidate exhibiting aggregation induced emission (ALE) was tested for its photophysical behaviour towards detection of various anions. The results showed that our receptor undergo ALE in >40% H2O-DMSO along with large pseudo Stokes shift (Delta lambda = 219 nm) and exhibit selective and sensitive detection towards hazardous cyanide’s oxidation product, cyanate (CNO-) ion over other tested anions. The blue-shifted fluorescence emission (lambda(em) = 492 nm) enhancement with large Stokes shift (Delta lambda = 144 nm) was observed with the increase in cyanate concentration. The synthesized turn-on sensor towards cyanate detection could be applied in real sample analyses as an improvement to the method currently carried out by international standards and hereby a different approach has been made for the detection of cyanide through its oxidation form, cyanate.

In Vitro and In Silico Evaluation of Anticancer Activity of New Indole-Based 1,3,4-Oxadiazoles as EGFR and COX-2 Inhibitors

Epidermal growth factor receptor (EGFR) and cyclooxygenase-2 (COX-2) are crucial targetable enzymes in cancer management. Therefore, herein, new 2-[(5-((1H-indol-3-yl)methyl)-1,3,4-oxadiazol-2-yl)thio]-N-(thiazol/benzothiazol-2-yl)acetamides (2a-i) were designed and synthesized as EGFR and COX-2 inhibitors. The cytotoxic effects of compounds 2a-i on HCT116 human colorectal carcinoma, A549 human lung adenocarcinoma, and A375 human melanoma cell lines were determined using MTT assay. 2-[(5-((1H-Indol-3-yl)methyl)-1,3,4-oxadiazol-2-yl)thio]-N-(6-ethoxybenzothiazol-2-yl)acetamide (2e) exhibited the most significant anticancer activity against HCT116, A549, and A375 cell lines with IC50 values of 6.43 +/- 0.72 mu M, 9.62 +/- 1.14 mu M, and 8.07 +/- 1.36 mu M, respectively, when compared with erlotinib (IC50 = 17.86 +/- 3.22 mu M, 19.41 +/- 2.38 mu M, and 23.81 +/- 4.17 mu M, respectively). Further mechanistic assays demonstrated that compound 2e enhanced apoptosis (28.35%) in HCT116 cells more significantly than erlotinib (7.42%) and caused notable EGFR inhibition with an IC50 value of 2.80 +/- 0.52 mu M when compared with erlotinib (IC50 = 0.04 +/- 0.01 mu M). However, compound 2e did not cause any significant COX-2 inhibition, indicating that this compound showed COX-independent anticancer activity. The molecular docking study of compound 2e emphasized that the benzothiazole ring of this compound occupied the allosteric pocket in the EGFR active site. In conclusion, compound 2e is a promising EGFR inhibitor that warrants further clinical investigations.

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.
