are defined herein. The present invention also relates to the discovery that compounds having Formula I-III are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled cell growth and spread of abnormal cells occurs.
The present invention relates generally to compositions and methods for treating cancer and neoplastic disease. Provided herein are substituted amidopyridine or amidopyridazine derivative compounds and pharmaceutical compositions comprising said compounds. The subject compounds and compositions are useful for inhibition histone demethylase. Furthermore, the subject compounds and compositions are useful for the treatment of cancer, such as prostate cancer, breast cancer, bladder cancer, lung cancer and/or melanoma and the like.
Novel quinone-fused oxazepines compounds that inhibit peroxiredoxins, pharmaceutical compositions comprising such compounds, are disclosed. Additionally, methods of treating or alleviating conditions associated with elevated peroxiredoxins levels, and in particular cancer, are also disclosed.

N-(2-Hydroxybenzyl)aminopyridines (L) react with Cu(II) and Pd(II) ions to form complexes in the compositions Cu(Li)2(CH3COO)(2) center dot nH(2)O (n = 0.14), Pd(L-i)(2)Cl-2 center dot nC(2)H(5)OH (n = 0, 2) and Pd(L-2)(2)Cl-2 center dot 2H(2)O- In the complexes, the ligands are neutral and monodentate which coordinate through pyridinic nitrogen. Crystal data of the complexes obtained from 2-amino pyridine derivative have pointed such a coordinating route and comparison of the spectral data suggests the validity of similar complexation modes of other analog ligands. Cu(II) complex of N-(2-hydroxybenzyl)-2-aminopyridine (L), [Cu(L-1)(2)(CH3COO)(2)] has slightly distorted square planar cis-mononuclear structure which is built by two oxygen atoms of two monodentate carboxylic groups disposed in cis-position and two nitroaen atoms of two pyridine rings. The remaining two oxygen atoms of two carboxylic groups form two Cu and H bridges containing cycles which joint at same four coordinated copper(II) ion. IR and electronic spectral data and the magnetic moments as well as the thermogravimetric analyses also specify on mononuclear octahedric structure of complexes [Cu(L-2)(2)(CH3COO)(2) center dot 2H(2)O] and [Cu(L-3)(2)(CH3COO)(2) center dot 4H(2)O] where L-2 and L-3 are N-(2-hydroxybenzyl)-2- or 3-aminopyridines, respectively. X-ray analysis for [Pd(L-1)(2)Cl-2 center dot 2C(2)H(5)OH] show square planar environment around Pd(II) ion formed by two chlorine atoms in trans position and two nitrogen atoms of pyridine rings. The spectral data indicate structural similarity in the complexes obtained via ligand exchange between PdCl2(PhCN)(2) and 3-amino and 4-aminopyridine derivatives. (c) 2007 Elsevier Ltd.
