3-Nitro-2-phenyl-2-trifluoromethyl-2H-chromenes in reactions with azomethine ylides from isatins and (thia)proline: synthesis of spiro[chromeno(thia)pyrrolizidine-11,3′-oxindoles]

1,3-Dipolar cycloaddition of stabilized azomethine ylides generated in situ from isatins and proline to 3-nitro-2-phenyl-2-trifluoromethyl-2H-chromenes in i-PrOH proceeds stereoselectively at room temperature and leads to the formation of hexahydro-6H-spiro[chromeno[3,4-a]-pyrrolizine-11,3′-indolin]-2′-ones with the cis arrangement of the trifluoromethyl group and the nitro group. A similar reaction with the participation of thiaproline-based ylides at 50 degrees C leads to mixtures of diastereomeric tetrahydro-6H,9H-spiro[chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazole-11,3′-indolin]-2′-ones with a predominance of the cis- or trans-isomer. The stereochemistry of the obtained products was confirmed by the NOESY experiment and X-ray structural analysis. GRAPHICS

Efficient synthesis and characterization of novel bis(chromenes) and bis(benzo[f]chromenes) linked to thiazole units

New carbothioamides, linked to chromene or benzo[f]chromene units, were taken as key synthons for the present study. These carbothioamides were prepared, in good yields, by the cyclocondensation of the appropriate 2-hydroxybenzaldehydes or 2-hydroxy-1-naphthaldehyde with 2-cyanoethanethioamide. Next, the precursors carbothioamides were reacted with different alpha-halocarbonyl compounds and bis(alpha-bromoketones). These reactions afforded the corresponding 4-(substituted)thiazoles and thiazol-4(5H)-ones, in addition to bis(thiazoles), linked to different cores. Additionally, thiazol-4(5H)-ones were condensed with the appropriate bis(aldehydes) to yield the corresponding bis(thiazol-4(5H)-ones), linked to chromene or benzo[f]chromene units via different cores.

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.

Synthesis and biological evaluation of thiazole derivatives on basic defects underlying cystic fibrosis

Cystic fibrosis is a genetic disease caused by loss-of-function mutations in the cystic fibrosis transmembrane conductance regulator gene, encoding for CFTR protein. The most frequent mutation is the deletion of phenylalanine at position 508 (F508del), which leads to distinct defects in channel gating and cellular processing. In last years, several thiazole containing small molecules, endowed with dual F508del-CFTR modulator activity, proved to be able to target these defects. In search of new chemical entities able to restore CFTR function, we designed and synthesized a small series of sixteen thiazole derivatives. The designed compounds were studied as correctors and potentiators of F508del-CFTR. Although none of the molecules showed significant corrector activity, compounds 10 and 11 exhibited potentiator effects, thus allowing to determine some basic structural features which enable to obtain F508del-CFTR potentiator activity. In silico ADME studies showed that these derivatives obey Lipinski’s rule of five and are expected to be orally bioavailable. Therefore, these molecules may represent a good starting point for the design of analogues endowed with improved CFTR potentiator activity and a good pharmacokinetic profile.

Synthesis, Docking and Anti-cancerous Activity of Some Novel Thiazole Derivatives of Biological Interest

Objectives: Heterocyclic compounds are enormously widespread in nature and have attracted research interest because of their pharmaceutical and biological properties. Amongst the heterocyclic rings, the thiazoles are the most important building blocks in today’s drug discovery and are found to have extensive biological activities against different types of diseases. Many potent anti-cancerous drugs like Tiazofurin are having 1,3 thiazole as an active ring structure and based on this theory, a new series of 2, 4 di substituted 1,3 thiazole derivatives were synthesized. Methods: First 2-amino-4-substituted phenyl thiazoles were synthesized by adapting a well-known Hantzsch reaction and subsequently 2-amino substituted derivatives were synthesized using various aryl aldehydes by following established Schiff’s reaction. The synthesized compounds were confirmed by TLC, IR, HNMR, CNMR and Mass Spectral Analysis. Then all the synthesized compounds were docked to RAS p21 receptor using PATCH DOCK Software to study their anti-cancerous activity. Then the compounds were screened for cancer cell line studies. Results: All the synthesized compounds exhibited some degree of anti-cancerous activity both in docking studies and in vitro anti-cancerous cell line studies. Conclusion: Amongst all the 16 synthesized, most compounds showed moderate to good anti-cancerous activity and the compounds S3P1c, S3P2c, S3P2d, S3P3a and S3P4d have shown the best activity.

Incorporation of thiazolothiazole fluorophores into a MOF structure: A highly luminescent Zn(II)-based MOF as a selective and reversible sensor for Cr2O72- and MnO4- anions

A highly luminescent Zn-II-MOF, [Zn-2 (TzTz)(2)(BDC)(2)]-2DMF, TzTz = 2,5-di (4-pyridyl)thiazolo I (Liu a al., 2019; Shen a al., 2018) [4,5]-d] thiazole and BDC = terephthalic acid), has been solvothermally assembled and fully characterized by single crystal X-ray crystallography, elemental analysis, FT-IR spectroscopy and X-ray diffraction (XRD). This transition-metal based luminescent MOF exhibits strong blue emission while capable as a selective sensor for detection of anions. Only trace amounts of fluorescent MOF can act as a highly selective and recyclable luminescent probe for the quantitative detection of Cr-VI and Mn-VII (Cr2O72-, MnO4-) : 4 anions in aqueous solutions with large quenching constants (9 x 10(7) M-1 and 4.8 x 10(3) M-1 for Cr2O72- and MnO4-) via an energy-transfer mechanism. The first sensing study of a TzTz-functionalized MOF material demonstrates the highest sensing ability among the previously reported fluorescent MOFs with detection limits for Cr2O72- and MnO4- ions in drinking water as low as 4 mu M (100 ppb).

One-Step Dyeing and Antimicrobial Finishing of PET Fabric with Novel 4-Arylazopyrazolone Disperse Dyes

Azopyrazole disperse dyes 8-12 could be synthesized either by condensing ethyl 3-hydroxy-2-aryldiazenyl butenoates 3-7 with S-methyl hydrazine carbodithioate 1 or by coupling the parent pyrazole 2 with diazotized aniline, p-substituted anilines and/or 4-aminoantipyrine. These dyes were applied to polyester fabrics using a high-temperature dyeing method at 120 degrees C and displayed yellow to orange hues. Raman spectra of the dyed samples undoubtedly excluded ring dyeing and were found to agree with the proposed structures. The synthesized disperse dyes were found to possess very good dyeing properties, as indicated by color strength measurements, and all of them except dye 12 had a color strength (K/S) value ranging from 19-23. The dyed fabrics exhibited excellent fastness to washing and dry and wet rubbing as well as light fastness, which varied from moderate to very good. The antimicrobial activities of the synthesized pyrazoles 2 and 8-12 as well as the dyed fabric samples against Escherichia coli and Staphylococcus aureus were measured, and the results showed very good activity.

Design of peptide-PEG-Thiazole bound polypyrrole supramolecular assemblies for enhanced neuronal cell interactions

Brain injuries, and neurodegenerative diseases can result in significant disability, lowered quality of life, and mortality. Current treatments including autologous nerve grafts are insufficient. This work presents the creation of new biomimetic supramolecular assemblies as a scaffold for potential applications in neural tissue regeneration. It is composed of polyethylene glycol amide core-conjugated with a thiazole-based building block and a peptide sequence (RVYNMGKGKGFCVPRPLVVYR). This peptide sequence is derived from laminin, a basal membrane protein, and a component of the extracellular matrix of neuronal cells. The product formed was allowed to self-assemble and bound to polypyrrole by layer-by-layer assembly to impart conductive properties (Lam-PEG-thiazole-PPy) resulting in the formation of fibrillar assemblies as indicated by electron microscopy studies. Rheological studies demonstrated that incorporation of PPy resulted in higher storage modulus indicative of higher ability to store deformation energy. Culture of rat olfactory-bulb derived neurons with the assemblies demonstrated that the Lam-PEG-thiazole-PPy assemblies promoted cell proliferation and were able to interact favorably with the cells. After 10 days of culture with the assemblies interconnected networks could be visualized. Furthermore, electrical stimulation resulted in a significant increase in axonal outgrowths. Thus, the assemblies presented herein exhibit potential for applications as a novel scaffold for neural tissue engineering.

Dual Parasiticidal Activities of Phthalimides: Synthesis and Biological Profile againstTrypanosoma cruziandPlasmodium falciparum

Chagas disease and malaria are two neglected tropical diseases (NTDs) that prevail in tropical and subtropical regions in 149 countries. Chagas is also present in Europe, the US and Australia due to immigration of asymptomatic infected individuals. In the absence of an effective vaccine, the control of both diseases relies on chemotherapy. However, the emergence of parasite drug resistance is rendering currently available drugs obsolete. Hence, it is crucial to develop new molecules. Phthalimides, thiosemicarbazones, and 1,3-thiazoles have been used as scaffolds to obtain antiplasmodial and anti-Trypanosoma cruziagents. Herein we present the synthesis of 24 phthalimido-thiosemicarbazones (3 a-x) and 14 phthalimido-thiazoles (4 a-n) and the corresponding biological activity againstT. cruzi, Plasmodium falciparum, and cytotoxicity against mammalian cell lines. Some of these compounds showed potent inhibition ofT. cruziat low cytotoxic concentrations in RAW 264.7 cells. The most active compounds,3 t(IC50=3.60 mu M),3 h(IC50=3.75 mu M), and4 j(IC50=4.48 mu M), were more active than the control drug benznidazole (IC50=14.6 mu M). Overall, the phthalimido-thiosemicarbazone derivatives were more potent than phthalimido-thiazole derivatives againstT. cruzi. Flow cytometry assay data showed that compound4 jwas able to induce necrosis and apoptosis in trypomastigotes. Analysis by scanning electron microscopy showed thatT. cruzitrypomastigote cells treated with compounds3 h,3 t, and4 jat IC(50)concentrations promoted changes in the shape, flagella, and surface of the parasite body similar to those observed in benznidazole-treated cells. The compounds with the highest antimalarial activity were the phthalimido-thiazoles4 l(IC50=1.2 mu M),4 m(IC50=1.7 mu M), and4 n(IC50=2.4 mu M). Together, these data revealed that phthalimido derivatives possess a dual antiparasitic profile with potential effects againstT. cruziand lead-like characteristics.
