Design, synthesis and biological evaluation of 1-Aryl-5-(4-arylpiperazine-1-carbonyl)-1H-tetrazols as novel microtubule destabilizers

A series of 1-aryl-5-(4-arylpiperazine-1-carbonyl)-1H-tetrazols as microtubule destabilizers were designed, synthesised and evaluated for anticancer activity. Based on bioisosterism, we introduced the tetrazole moiety containing the hydrogen-bond acceptors as B-ring of XRP44X analogues. The key intermediates ethyl 1-aryl-1H-tetrazole-5-carboxylates 10 can be simply and efficiently prepared via a microwave-assisted continuous operation process. Among the compounds synthesised, compound 6–31 showed noteworthy potency against SGC-7901, A549 and HeLa cell lines. In mechanism studies, compound 6–31 inhibited tubulin polymerisation and disorganised microtubule in SGC-7901 cells by binding to tubulin. Moreover, compound 6–31 arrested SGC-7901cells in G2/M phase. This study provided a new perspective for development of antitumor agents that target tubulin.

Sustainable carbonecarbon bond formation catalyzed by new oxamate-containing palladium(II) complexes in ionic liquids

New and versatile bis(oxamato)palladate(II) complexes of formula (n-Bu 4N)2[Pd(2-Mepma)2]·4H2O (1a) and (n-Bu4N)2[Pd(4-Mepma)2]·2H 2O·MeCN (1b) (n-Bu4N+ = tetra-n-buthylammonium, 2-Mepma = N- 2-methylphenyloxamate and 4-Mepma = N-4-methylphenyloxamate) have been synthesized and characterized by spectroscopic methods and single crystal X-ray diffraction. Each palladium(II) ion in 1a and 1b is four-coordinate with two oxygen and two nitrogen atoms from two fully deprotonated oxamate ligands building a centrosymmetric square planar surrounding. Their catalytic role has been investigated for both Heck and Suzuki coupling reactions using a series of aryl iodide/bromide derivatives in tetra-n-butylammonium bromide (n-Bu 4NBr) as ionic liquid, i.e. molten salt. These precatalysts appear as highly efficient, easily recovered and reused at least eight times without any drastic loss of their exceptional reactivity or leaching from the ionic liquid medium.

Synthesis and biological evaluation of novel oxalamido derivatives as caspase-3 inhibitors

A new series of 5-fluoro-3-[(4-substituted-phenylaminooxalyl)-amino]-4-oxo- pentanoic acid, 7a-c, 3-[(4-substitutedphenylaminooxalyl)- amino]-4-oxo-5-(2,3, 5,6-tetrafluoro-phenoxy)-pentanoic acid, 7d-h and 5-(2,6-difluoro-phenoxy)-3- [(substituted-phenylaminooxalyl)-amino]-4-oxo-pentanoic acid, 7i-p have been synthesized from N-(substituted-phenyl)- oxalamic acid, 1 and their activities have been evaluated in vitro. Compounds 7b,c and k show low micromolar inhibitory activity against caspase-3.

Synthesis, crystal structure, and insecticidal activity of novel N-alkyloxyoxalyl derivatives of 2-arylpyrrole

Two series of novel N-alkyloxyoxalyl derivatives of 2-arylpyrrole were synthesized, and their structures were characterized by 1H NMR spectroscopy, elemental analysis, and single-crystal X-ray diffraction analysis. The insecticidal activities of the new compounds were evaluated. The results of bioassays indicated that some of these title compounds exhibited excellent insecticidal activities, and their insecticidal activities against oriental armyworm, mosquito, and spider mite are comparable to those of the commercialized Chlorfenapyr.

Synthesis of 2-(arylamino)-2-(arylimino)acetamides

The reaction of 2-(arylamino)-2-oxoacetates with PCl5 afforded 2-(arylamino)-2,2-dichloroacetates. The reaction of these compounds with aniline derivatives allowed a convenient synthesis of a great variety of 2-(arylamino)-2-(arylimino)acetamides. Wiley-VCH Verlag GmbH & Co.

Triphenylphosphine-catalyzed simple synthesis of dimethyl 1-aryl-4-ethoxy-5-oxo-4,5-dihydro-1H-pyrrole-2,3-dicarboxylates
