The use of isoxazoline and isoxazole scaffolding in the design of novel thiourea and amide liquid-crystalline compounds

A series of novel thiourea and amide liquid crystals containing 5-membered isoxazoline and isoxazole rings were synthetized and the liquid crystal properties studied. Thioureas were obtained using a condensation reaction of benzoyl chlorides, arylamines and ammonium thiocyanate. The amides, on the other hand, were the byproduct of a quantitative reaction which used potassium cyanate as the starting material. Thiourea and amide derivatives were predominantly SmA mesophase inductors. A nematic mesophase was observed only for thioureas and amides containing an isoxazole ring. Additionaly, the liquid crystal behavior was also dependent on the relative position of nitrogen and oxygen atoms on the 5-membered heterocycle.

Efficient synthesis of bis-isoxazole ethers via 1,3-dipolar cycloaddition catalysed by Zn/Zn2+ and their antifungal activities

An efficient method was developed for synthesising isoxazoles. A series of novel bis-isoxazole ether compounds VI, VII and VIII were synthesised starting from different substituted aldehydes (I) via a 1,3-dispolar cycloaddition using Zn/Zn2+ as a catalyst; these were characterised by FT-IR, HRMS, H-1 NMR and C-13 NMR spectroscopy. In addition, the antimicrobial properties of the synthesised products were investigated. The synthesised compounds exhibited significant antifungal activities in comparison with the standard drugs, fluconazole and itraconazole. It was found that Candida albicans was sensitive to 2-substituted phenyl bis-isoxazole ethers bearing pyridyl. (C) 2015 Institute of Chemistry, Slovak Academy of Sciences

Comparison of Anti-Aggregation Activities of 5-Phenyl-3-(3-Pyridyl)Isoxazole and 5-Phenyl-3-(3-Pyridyl)-1,2,4-Oxadiazole

Two bioisosteric analogs, 5-phenyl-3-(3-pyridyl)isoxazole and 5-phenyl-3-(3-pyridyl)-1,2,4-oxadiazol, were synthesized so as to compare their antiaggregatory activities, determine the pharmacologically active fragment in the molecules of this type, and to explore the action mechanisms of the potential antiaggregatory compounds belonging to the class of 3,5-substituted isoxazoles. Antiaggregatory activities of these compounds were studied in vitro using aggregation inductors arachidonic acid, adenosine diphosphate, and adrenaline. It was shown that 5-phenyl-3-(3-pyridyl)-1,2,4-oxadiazole and 5-phenyl-3-(3-pyridyl)isoxazole completely suppressed the platelet aggregation induced by arachidonic acid and the second wave of the platelet aggregation induced by adrenaline or adenosine diphosphate. Antiaggregatory activity of substituted isoxasole was 1.1-1.5 times higher than that of substituted oxadiazole. In contrast to the isoxazole analog, 5-phenyl-3-(3-pyridyl)-1,2,4-oxadiazole at concentrations of 300-400 mu M partially suppressed the first wave of aggregation induced by adenosine diphosphate. It was demonstrated that both compounds at concentrations up to 250 mu M were not thrombin inhibitors in vitro. Thus, the introduction of nitrogen atom into the C4-position of the isoxazole ring changes the molecule properties. This suggests that the entire isoxazole and 1,2,4-oxadiazole rings belong to the pharmacophoric fragments of the molecules but not parts of the rings as it was supposed earlier.

Design, synthesis and cytotoxic activities of scopoletin-isoxazole and scopoletin-pyrazole hybrids

12 novel scopoletin-isoxazole and scopoletin-pyrazole hybrids were designed, synthesized and their chemical structures were confirmed by HR-MS, IR, H-1 NMR and C-13 NMR spectra. The anticancer activities of the newly synthesized compounds were evaluated in vitro against three human cancer cell lines including HCT-116, Hun7 and SW620 by MTT assay. The screening results showed that six compounds (9a, 9c, 9d, 12a, 18b and 18d) exhibited potent cytotoxic activities with IC50 values below 20 mu M. Besides, we have further evaluated the growth inhibitory activities of six compounds against the human normal tissue cell lines HFL-1. Especially, compound 9d displayed significant anti-proliferative activity with IC50 values ranging from 8.76 mu M to 9.83 mu M and weak cytotoxicity with IC50 value of 90.9 mu M on normal cells HFL-1, which suggested that isoxazole-based hybrids of scopoletin were an effective chemical modification to improve the anticancer activity of scopoletin.
