  The synthesis of 4,6-diaryl-2-pyridones and their bioactivation in CYP1 expressing breast cancer cells

  摘要：

  As part of a programme to develop anticancer prodrugs which are activated by cytochrome P450 (CYP) 1B1, a library of 4,6-diaryl-2-pyridones was synthesised in yields of 6-60% from the corresponding chalcones. A number of these derivatives showed promising antiproliferative activities in human breast cancer cell lines which express CYP1B1 and CYP1A1, while showing little toxicity towards a non-tumour breast cell line with no CYP expression. Metabolism studies provided evidence supporting the involvement of CYP1 enzymes in the bioactivation of these compounds.

  The present invention provides novel radiopharmaceuticals useful for the diagnosis of infection and inflammation, reagents and kits useful for preparing the radiopharmaceuticals, methods of imaging sites of infection and/or inflammation in a patient, and methods of diagnosing diseases associated with infection or inflammation in patients in need of such diagnosis. The radiopharmaceuticals bind in vivo to the leukotriene B4 (LTB4) receptor on the surface of leukocytes which accumulate at the site of infection and inflammation. The reagents provided by this invention are also useful for the treatment of diseases associated with infection and inflammation.

• .omega.-[(4,6-Diphenyl-2-pyridyl)oxy]alkanoic acid derivatives: a new family of potent and orally active LTB4 antagonists

  A series of omega-[(4,6-diphenyl-2-pyridyl)oxy]alkanoic acid derivatives was prepared which inhibited the binding of leukotriene B4 to its receptors on guinea pig spleen membranes and on human polymorphonuclear leukocytes (PMNs) and selectively antagonized the LTB4-induced elastase release in human PMNs. On the basis of these three screens, a structure-activity relationship was investigated. Alpha-Substitution on the carboxylic acid side chain led to only small changes in the binding affinities but greatly enhanced the LTB4 antagonist activity. Substitution on the phenyl rings was also evaluated. The terminal carboxylic acid function can be replaced by a tetrazole ring without loss in activity. The beat in vitro LTB4 antagonists of this series were investigated in vivo in the inhibition of LTB4-induced leukopenia in rabbits. Compound 9b (RP69698) displayed potent LTB4 antagonist activity, after oral administration, with an ED50 value of 6.7 mg/kg.
