  Provided are methods and compositions for use in therapy, and in particular for treating cancer, preferably drug-resistant cancer, and/or radiation resistant cancer. The compounds may be used for reducing tumor size in a mammalian subject and for inducing apoptosis in a tumor cell. The methods are effective on tumor cells that are resistant to drugs such as temozolomide, doxorubicin, and geldanamycin, as well as non-resistant tumor cells. Further provided are barbiturate and thiobarbiturates diene compounds for use in treating cancer, and uses, methods and compositions relating to these compounds.

• Synthesis and mechanism of formation of oxadeazaflavines by microwave thermal cyclization of ortho-halobenzylidene barbiturates
  作者：J. Daniel Figueroa-Villar、Sandra C. G. de Oliveira

  DOI：10.1590/s0103-50532011001100012

  日期：——

  The thermal cyclization reaction of o-halobenzylidene barbiturates was developed as an efficient and simple method for the preparation of oxadeazaflavines. The use of solid state reaction conditions with microwave irradiation afforded the products in 5 min with 47 to 98% yield. Experimental synthetic results and thermogravimetric reaction analyses agree with the molecular modeling mechanism simulation, indicating that this reaction occurs through an intramolecular hetero-Diels-Alder cyclization followed by fast re-aromatization.
• Nuclear magnetic resonance and molecular modeling study of exocyclic carbon–carbon double bond polarization in benzylidene barbiturates
  作者：J. Daniel Figueroa-Villar、Andreia A. Vieira

  DOI：10.1016/j.molstruc.2012.09.021

  日期：2013.2

  Benzylidene barbiturates are important materials for the synthesis of heterocyclic compounds with potential for the development of new drugs. The reactivity of benzylidene barbiturates is mainly controlled by their exocyclic carbon-carbon double bond. In this work, the exocyclic double bond polarization was estimated experimentally by NMR and correlated with the Hammett sigma values of the aromatic ring substituents and the molecular modeling calculated atomic charge difference. It is demonstrated that carbon chemical shift differences and NBO charge differences can be used to predict their reactivity. (C) 2012 Elsevier B.V. All rights reserved.
