Potential Anticancer Agents. I. Synthesis of Isoxazole Moiety Containing Quinazoline Derivatives and Preliminarily in vitro Anticancer Activity

14 new structures of isoxazole-moiety-containing quinazoline derivatives(3a similar to 3n) were synthesized for the first time and characterized by IR, H-1 NMR, C-13 NMR, ESI-MS.

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.

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.

Efficient microwave assisted synthesis and computational study of isoxazole Schiff base as an antibacterial agent

Seven isoxazole containing Schiff bases 1-7 have been synthesized by the reaction of 5-amino-3,4-dimethylisoxazole and the corresponding active aldehyde. The structures of synthesized compounds have been established using spectroscopic (H-1 and C-13 NMR, FT-IR and MS) and elemental analyses. These compounds have been assayed by the disk diffusion method for antibacterial activity against two Gram-positive and two Gram-negative bacteria from which the minimum inhibitory concentration have been determined. Their molecular properties have also been calculated computationally to corroborate the antibacterial activity. Experimental and computational results indicate that chloro derivative of isoxazole Schiff base 4 is a better antibacterial agent than Amoxicillin.

A fluorescence-active modified BINOL with heteroaromatic fused rings containing two different heteroatoms is synthesized in good yield. Its racemate form is well characterized by chiral HPLC analysis. The molecule bears sterically hindered geometry and has potential for stereochemical properties normally exhibited by BINOLs. The molecule has two ends with different ligating atoms in the form of hydroxy groups at one end and isoxazole ring heteroatoms on the other end. This feature may be useful for molecular recognition of both hard and soft cations.

Synthesis, potentiometric and antimicrobial studies on metal complexes of isoxazole Schiff bases

The metal complexes of Cu(II), Ni(II) and Co(II) with Schiff bases of 3-(2-hydroxy-3-ethoxybenzylideneamino)-5-methyl isoxazole [HEBMI] and 3-(2-hydroxy-5-nitrobenzylidene amino)-5-methyl isoxazole [HNBMI] which were obtained by the condensation of 3-amino-5-methyl isoxazole with substituted salicylaldehydes have been synthesized. Schiff bases and their complexes have been characterized on the basis of elemental analysis, magnetic moments, molar conductivity, thermal analysis and spectral (IR, UV, NMR and Mass) studies. The spectral data show that these ligands act in a monovalent bidentate fashion, co-ordinating through phenolic oxygen and azomethine nitrogen atoms. Chelates of Co(II), Ni(II) appear to be octahedral and Cu(II) appears to be distorted octahedral. To investigate the relationship between formation constants of binary complexes and antimicrobial activity, the dissociation constants of Schiff bases and. stability constants of their binary metal complexes have been determined potentiometrically in aqueous solution at 30 +/- 1 degrees C and at 0.1 M KNO3 ionic strength and discussed. Antimicrobial activities of the Schiff bases and their complexes were screened. The structure-activity correlation in Schiff bases and their metal(II) complexes are discussed, based on the effect of their stability constants. It is observed that the activity enhances upon complexation and the order of activity is in accordance with stability order of metal ions. (C) 2007 Elsevier B.V. All rights reserved.
