Benzoyl 2-methyl indoles as selective PPARγ modulators
摘要:
Routine screening for human PPAR ligands yielded compounds 1 and 2, both of which were sub-micromolar hPPARgamma agonists. Synthetic modifications of these leads led to a series of potent substituted 3-benzyl-2-methyl indoles, a subset of which were noted to be selective PPARgamma modulators (SPPARgammaMs). SPPARgammaM 24 displayed robust anti-diabetic activity with an improved therapeutic window in comparison to a PPARgamma full agonist in a rodent efficacy model. (C) 2004 Elsevier Ltd.

[reaction: see text] X = CH2, C[double bond]O, R2 = H, alkyl. A general method was developed for the one-pot synthesis of highly functionalized indoles from simple, commercially available aryl hydrazines and cyclicenolethers. Enol lactones were also used as substrates, affording substituted indole acetic acid or indole propionic acid derivatives. This procedure affords 2,3-disubstituted indoles as

The presently disclosed subject matter provides derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) that are characterized by substantially reduced cyclooxygenase inhibiting activity, yet retain the ability to interact with and modulate the activities of other polypeptides such as the class of peroxisome proliferators-activated receptors (PPARs) and γ-secretase. Also provided are methods of using the derivatives to treat pathological disorders.

The preparation, spectroscopic and magnetic properties of ML(2)Cl(2) (M = Cu(II), Mn(II), Ni(II)) and [ML(3)]Cl(3) (M = Fe(III), Cr(III)), L = N-4-methoxyphenyl-N-4-chlorobenzoyl hydrazide are reported. In all the studied complexes the N-4-methoxyphenyl-N-4-chlorobenzoyl hydrazide acts as a neutral bidentate chelating ligand with coordination involving the carbonyl oxygen and nitrogen atom of the secondary hydrazide group. The complexes appear to have an pseudo-octahedral stereochemistry. ESR parameters (g(1) = 4.432, g(2) = 1.991, D = 0.096 cm(-1)) and mu(eff) = 3.55 mu g Obtained for [CrL(3)]Cl(3) also suggest the possibilities of magnetic dipole-dipole coupling interactions between Cr(III) ions.
