Synthesis and Biological Evaluation of Some Novel Isoxazole Derivatives

The reaction of 5-amino-3- methylisoxazole (1) with formalin and secondary amines gave the corresponding Mannich bases 3-6. Alkylation of isoxazole derivative 1 with Mannich bases hydrochloride gave unsubstituted isoxazolo[5,4-b] pyridine derivatives 8a, b via alkylation at position 4. Moreover, coupling reaction of 1 with different diazonium salts gave the corresponding mono and bisazo dyes of isoxazole derivative. The newly synthesized compounds were screened for their antitumor activity compared with 5-fluorouracil as a wellknown cytotoxic agent using Ehrlich ascites carcinoma cells. Interestingly, the obtained results showed clearly that compounds 3, 15, 8b, 4, 8a, and 5 exhibited high antitumor activity than 5-fluorouracil.

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.

PREPARATION OF CROWN ETHERS WITH ISOXAZOLYL-LARIATS – HOMOLOGATION OF ISOXAZOLE ALDEHYDES, AND A CRITICAL COMPARISON OF LARIAT FUNCTIONAL MOIETIES FOR LANTHANIDE EXTRACTION

A critical comparison of several lariat ether functional moieties is presented. The synthesis of two isoxazolyl-lariat ethers is described. The lariat ether (2, n = 1) undergoes B-fragmentation on electron transfer reductive ring-opening with samarium diiodide. The isoxazole moiety was then homologated to overcome this problem, and isoxazole lariat ether (2, n = 3) was obtained. The isoxazole (2, n = 3) and beta-diketone (3, n = 3) crowns were evaluated in lanthanide shift studies and liquid-liquid extraction studies. Finally, lateral metalation and electrophilic quenching with carbon dioxide produced the carboxylic acid (12) which proved to be an efficient ligand for the liquid-liquid extraction of lanthanides.

Design and synthesis of sinomenine isoxazole derivatives via 1,3-dipolar cycloaddition reaction

A novel structure of sinomenine isoxazole derivatives is synthesised from sinomenine hydrochloride and aromatic aldehydes and requires six steps. 19 target compounds have been obtained in good yields. The sinomenine hydrochloride transforms to 4-alkynyl sinomenine, which is a key intermediate product to synthesise the target sinomenine isoxazole compounds, after a neutralisation reaction with ammonia and substitution reaction with 3-chloropropyne. Another key intermediate product is 1,3-dipole, which can be obtained from aromatic aldehyde. After treatment with hydroxylamine hydrochloride and then sodium carbonate solution, aromatic aldehyde is converted to aldehyde oxime, which reacts with N-chlorosuccinimide (NCS) to afford aryl hydroximino chloride. 1,3-Dipole is eventually formed in situ while triethylamine (TEA) in DMF is added dropwise. Then 4-alkynyl sinomenine is added to provide the sinomenine isoxazole derivative via 1,3-dipolar cycloaddition reaction as the key step. All the target compounds are characterised by melting point, H-1 NMR, C-13 NMR, HRMS and FT-IR spectroscopy.
