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.

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.

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, 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.

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.

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.

Novel approach of multi-targeted thiazoles and thiazolidenes toward anti-inflammatory and anticancer therapy-dual inhibition of COX-2 and 5-LOX enzymes

It is well established that cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) play a vital role in the initiation and progression of inflammatory reactions. Hence, thiazole and thiazolidene-based pharmacophore molecules were synthesized to obtain dual COX-2 and 5-LOX inhibitory activity. The synthesis of target compounds has been achieved by a novel green strategy. In vitro COX-1, COX-2, and 5-LOX evaluation of these molecules have shown the potential for an improved anti-inflammatory profile. Most promising compound among the series (2-(diphenylamino)-4-(4-nitrophenyl)thiazol-5-yl)(naphthalen-1-yl)methanone 7h (IC50 = 0.07 +/- 0.02 mu M) showed equivalent COX-2 inhibitory potency as that of positive control etoricoxib (IC50 = 0.07 +/- 0.01 mu M) and an enhanced selectivity index of 115.14. Compound 7h exhibited 5-LOX IC50 of 0.29 +/- 0.09 mu M and reference drug zileuton showed IC50 of 0.15 +/- 0.05 mu M. In vivo studies of 7h including carrageenan-induced paw edema assay (63% inhibition of paw edema), antiulcer studies, biochemical assays, qRT-PCR analysis, and anticancer studies indicated that the present study has identified a good lead compound for the development of a potential anti-inflammatory drug having improved gastric safety profile.

An enzyme-free DNA circuit-assisted MoS2 nanosheet enhanced fluorescence assay for label-free DNA detection

A fluorescence strategy for highly sensitive and selective detection of H5N1 DNA was proposed based on MoS2 nanosheets and catalytic hairpin assembly. This platform not only avoided any labeling but also reduced the background signal. In the absence of target, CHA could not be triggered and the thiazole orange and MBs complexes were adsorbed on the surface of MoS2 to quench the fluorescence of TO, resulting in low background signal. However, upon addition of target DNA, the CHA was initiated and produced plenty of MBs duplex which could be far away from the surface of MoS2 and bind to TO to enhance its fluorescence. This approach exhibited excellent sensitivity and specificity for H5N1 DNA with a detection limit of 7.5 pM, and realized the assay of H5N1 DNA in human serum samples. Furthermore, this platform could be expanded to detect other virus DNA by changing the corresponding molecular beacons, holding the potential of clinical application.
