Synthesis of 4-(2-hydroxyphenyl)-5,6,7,8-tetrahydroisoxazolo[5,4-b]chromene-5(4H)-ones

The aim of this work is the synthesis of new tetraheterocyclic compounds of interest as potential biologically active substances that include the isoxazole and chromone moieties in their structure. The synthesis of such compounds was carried out with two stages. By Knoevenagel condensation of 3-methyl-1,2-isoxazol-5(2H)-on with salicylic aldehyde (4Z)-4-(2-hydroxybenzyliden)- 3-methyl-1,2-oxazol-5(4H)-on was obtained. In this reaction an excess of half of the aldehyde equivalent was used to increase the yield of the product. Pyperidine was used as a catalyst. The reaction was carried out by boiling the components in ethyl acetate. The reaction of the resulting benzylidenisoxazole derivative with cyclohexane-1,3-dione or dimedone was performed by boiling the components in ethanol without the use of a catalyst. The interaction mechanism includes heterodiene Dielsa-Aldera condensation followed by dehydration of one water molecule. As a result, 3-methyl-4-(2-hydroxyphenyl-5,6,7,8-tetrahydroisoxazolo[5,4-b]chromene-5(4H)-one and 3,7,7-trimethyl-4-(2-hydroxyphenyl)-5,6,7,8,9-tetrahydroisoxazolo[5,4-b]chromen-5(4H)-one were obtained. Purification of the synthesized compounds was carried out by crystallization from ethanol. All the obtained compounds were characterised by IR 1H NMR and UV spectroscopies. In 1H NMR spectra there are signals of the methyl groups of the isoxazole ring of compounds at 2.26, 2.29, 2.34 ppm respectively. In the UV spectrum of a plane molecule of (4Z)-4-(2- hydroxybenzyliden)-3-methyl-1,2-oxazol-5(4H)-on there is a long-wave absorption maximum (400.9 nm) corresponding to the joint system of conjugated bonds of the isoxazole and aromatic rings. The structures of the obtained compounds were confirmed by high resolution massspectrometry analysis. In the spectra of 3-methyl-4-(2-hydroxyphenyl-5,6,7,8-tetrahydroisoxazolo[5,4- b]chromene-5(4H)-one and 3,7,7-trimethyl-4-(2-hydroxyphenyl)-5,6,7,8,9-tetrahydroisoxazolo[5,4- b]chromen-5(4H)-one the[M + Na]+ ion peaks were observed. The presence of fragment peaks [M + Na – CO]+ and [M + Na – CO – H2O]+ confirms the presence of hydroxy and carbonyl groups in the molecules.

Identification of Potential Inhibitors of the Antigen 85C of Mycobacterium tuberculosis from Natural Resources by Virtual Screening

Tuberculosis, caused by Mycobacterium tuberculosis, is one of the deadliest infections in the world and, therefore, the search for new therapeutic alternatives is strongly required. A promising etiological agent?s molecular target for drug development is one of the mycolyltransferase enzymes, the 85C antigen (Ag85C), since it is crucial for the biosynthesis of myolates, essential elements of the bacterial cell wall. In this perception, the present work aimed to identify potential inhibitors against M. tuberculosis Ag85C by hierarchical virtual screening. For this, the ZINC15 natural products database was subjected to chemical similarity screening in order to select molecules in biologically relevant space. Subsequently, molecular docking was employed to list the natural products selected in the previous step according to their affinity to the enzyme active site. The complex with the best binding affinity was submitted to Molecular Dynamics (MD) simulation with the aim of evaluating its mechanical stability. Among 100,095 evaluated compounds, the isoxazoline derivative ZINC000107283125 was top ranked (GridScore -84.65 Kcal/mol), and therefore submitted to MD simulations. According to RMSD analysis there was less fluctuation of protein residues in the HOLO form than in the APO form, which indicates that ZINC000107283125 was able to stabilize the protein structure. The observed intermolecular (protein-ligand) interactions were similar to those described in the literature, of these, we highlight the hydrogen bond with Ser125. Therefore, this study contributed for the search of new and more selective and potent drugs against Ag85C.

Synthesis, characterization, biological activities and molecular modeling of Schiff bases of benzene sulfonamides bearing curcumin scaffold

Curcumin has shown large number of pharmacological properties against different phenotypes of various disease models. Different synthetic routes have been employed to develop its various derivatives for diverse biological functions. In this study Schiff bases of benzenes sulfonamides bearing curcumin scaffold were synthesized to investigate their pharmacological effects. The structures of newly synthesized compounds were described by IR, 1H NMR and 13C NMR spectral data. The anti-inflammatory and antinociceptive activities of new compounds were evaluated with indomethacin and diclofenac sodium in experimental animal models respectively. COX-2 enzyme inhibition was evaluated with synthesized compounds through in vitro cyclooxygenase assays. Inhibition assays result revealed that compound 3a was the most potent compound. Molecular docking studies were also performed to identify the plausible binding mode of this compound. Antibacterial and antifungal activities were evaluated with ciprofloxacin, nystatin and ketoconazole using disk diffusion method and minimum inhibitory concentration values were determined by 96-well plate assay method. Our studies showed that compound 3a has promising antibacterial and anti-inflammatory while 3c has better antifungal activity as compared to reference drugs. Similarly the combination of more potent compounds 3a and 3c with ciprofloxacin and nystatin respectively gave significant synergic effect.

Synthesis, docking, antioxidant, antihyperlipidemic, antiplatelet, anticoagulant, and vasodilatory activities of isoxazole newly synthesized derivative

We synthesized isoxazole derivative: 4-({4-(dimethylamino) phenyl}methylidene)-3-methyl-1,2-isoxazole-5(4H)-one (PMX-5), characterized by FTIR,1H-NMR and13C-NMR. In computational anal-ysis, PMX-5 showed high affinity for farnesoid X receptor, glycoprotein-VI, vitamin-K epoxide reductase, and guanylyl cyclase. At concentrations of 1, 3, 10, 100, 300, 700, and 1000 mug/mL, it exhibited free radical scavenging effect as 3.2743 ¡À 0.48, 10.8036 ¡À 2.79, 15.2931 ¡À 3.38, 29.6991 ¡À 0.08, 37.2992 ¡À .59, 47.4319 ¡À 0.51, and 63.5001 ¡À 1.23%, respectively. In high fat diet-induced hyperlipidemia, PMX-5 lowered total cholesterol, triglyceride, low-density lipoprotein, and very low-density lipoprotein levels, while elevated high-density lipoprotein levels significantly (p < 0.001 vs. saline) in rats. PMX-5 suppressed arachidonic acid and adenosine diphosphate-induced platelet aggregation with IC50 values of 192 and 831 muM, respec-tively. It also showed anticoagulant potential by increasing plasma recalcification time to 101.2 ¡À 2.4 s at 30 muM, 108 ¡À 2.2 s at 100 muM, 132.2 ¡À 2.9 and 202.4 ¡À 4.6 s (p < 0.001) at 300 and 1000 muM, respectively. PMX-5 partly relaxed phenylephrine and K+ (80 mM)-induced contractions in isolated rat aortic tissues. Thus, the current study reports the synthesis of PMX-5 and its pharmacological potentials. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Human galectin-1 and its inhibitors: Privileged target for cancer and HIV

Galectin 1(Gal-1), a beta-galactoside binding mammalian lectin of 14KDa, is implicated in many signalling pathways, immune responses associated with cancer progression and immune disorders. Inhibition of human Gal-1 has been regarded as one of the potential therapeutic approaches for the treatment of cancer, as it plays a major role in tumour development and metastasis by modulating various biological functions viz. apoptosis, angiogenesis, migration, cell immune escape. Gal-1 is considered as a biomarker in diagnosis, prognosis and treatment condition. The overexpression of Gal-1 is well established and seen in many types of cancer progression like osteosarcoma, breast, lung, prostate, melanoma, etc. Gal-1 greatly accelerates the binding kinetics of HIV-1 to susceptible cells, leading to faster viral entry and a more robust viral replication by specific binding of CD4 cells. Hence, the Gal-1 is considered a promising molecular target for the development of new therapeutic drugs for cancer and HIV. The present review laid emphasis on structural insights and functional role of Gal-1 in the disease, current Gal-1 inhibitors and future prospects in the design of specific Gal-1 inhibitors.

Cross-beta polymerization of low complexity sequence domains

Most transcription factorsand RNA regulatory proteins encoded by eukaryotic genomes ranging from yeast to humans contain polypeptide domains variously described as intrinsically disordered, prion-like, or of low complexity (LC). These LC domains exist in an unfolded state when DNA and RNA regulatory proteins are studied in biochemical isolation from cells. Upon incubation in the puri?ed state, many of these LC domains polymerize into homogeneous, labile amyloid-like ?bers. Here, we consider several lines of evidence that may favor biologic utility for LC domain polymers.

Ultrafast photodegradation of isoxazole and isothiazolinones by UV254 and UV254/H2O2 photolysis in a microcapillary reactor

The photodegradation process of methylisothiazolinone (MIT), benzisothiazolinone (BIT), and isoxazole (ISOX) in ultrapure water and synthetic wastewater by means of UV254 photolysis and by UV254/H2O2 advanced oxidation process were investigated in a microcapillary photoreactor designed for ultrafast photochemical transformation of microcontaminants. For the first time, we estimated key photo-kinetic parameters, i.e. quantum yields (35.4 mmol¡¤ein?1 for MIT, and 13.5 and 55.8 mmol¡¤ein?1 for BIT at pH = 4?6 and 8, respectively) and rate constants of the reaction of photo-generated OH radicals with MIT and BIT (2.09¡¤109 and 5.9¡¤109 L mol?1¡¤s?1 for MIT and BIT). The rate constants of the reaction of photo-generated OH radicals with ISOX in MilliQ water was also estimated (2.15¡¤109 L mol?1¡¤s?1) and it was in good agreement with literature indications obtained in different aqueous matrices. The models were extended and validated to the case of simultaneous degradation of mixtures of these compounds and using synthetic wastewater as an aqueous matrix. High resolution-accurate mass spectrometry analysis enabled identification of the main intermediates (BIT200, B200, saccharin, BIT166) and enabled proposal of a novel degradation pathway for BIT under UV254/H2O2 treatment. This study demonstrates an ultrafast method to determine key photo-kinetic parameters of contaminants of emerging concern in water and wastewater, which are needed for design and validation of photochemical water treatment processes of municipal and industrial wastewaters.

A comprehensive insight into the chemical space and ADME features of small molecule NS5A inhibitors

Non-structural 5A (NS5A) protein plays a crucial role in the replication of hepatitis C virus (HCV) and during the past decade has attracted increasing attention as a promising biological target for the treatment of viral infections and related disorders. Small-molecule NS5A inhibitors have shown significant antiviral activity in vitro and in vivo. Several lead molecules are reasonably regarded as novel highly potent drug candidates with favorable ADME features and tolerable side effects. The first-in-class daclatasvir has recently been launched into the market and 14 novel molecules are currently under evaluation in clinical trials. From this perspective, we provide an overview of the available chemical space of small-molecule NS5A inhibitors and their PK properties, mainly focusing on the diversity in structure and scaffold representation.

Gold-Catalyzed [4 + 1]-Annulation Reactions between 1,4-Diyn-3-ols and Isoxazoles to Construct a Pyrrole Core

This work reports gold-catalyzed [4 + 1]-annulation reactions between 1,4-diyn-3-ols and isoxazoles or benzisoxazoles to yield pyrrole derivatives. The reaction chemoselectivity is controlled by an initial attack of an isoxazole at a less hindered alkyne to form gold carbenes, further inducing a 1,2-migration of a second alkyne group. A broad substrate scope of 1,4-diyn-3-ols, isoxazoles and even benzisoxazoles highlighted the reaction utility.
