PLATINUM(IV) COMPLEXES WITH PURINE OR PYRIMIDINE AND IMIDAZOLE DERIVATIVES

Pt(IV) mixed chloride complexes with purine or pyrimidine and imidazole derivatives have been prepared and characterized. The compounds have general formula [Pt(L1)(L2)Cl4], where L1 = purine (pur) or pyrimidine (pyr) and L2 = N-methylimidazole (N-MeIm), N-ethylimidazole (N-EtIm) or N-propylimidazole (N-PropIm), except for the complex [Pt(pur)(pyr)CI4]. The nitrogen bases act as monodentate ligands coordinated via nitrogen. The far i.r. and electronic reflectance spectra indicate a hexacoordinate geometry. The complexes competitively inhibit lentil amine oxidase, with highest inhibition for [Pt(pur)(N-EtIm)Cl4].

The oxindole/imidazole derivative C16 reduces in vivo brain PKR activation

Inhibition of double-stranded RNA-dependent protein kinase (PKR) represents an interesting strategy for neuroprotection. However, inhibiting this kinase which triggers the apoptotic process could favour in counterpart cell proliferation and tumorigenesis. Here, we use an in vivo model of 7-day-old rat displaying a high activation of brain PKR to investigate the effects of a new PKR inhibitor identified as an oxindole/imidazole derivative (06). We show for the first time that acute systemic injection of C16 specifically inhibits the apoptotic PKR/eIF2 alpha signaling pathway without stimulating the proliferative mTOR/p7OS6K signaling mechanism.

FORMATION AND ANTIMYCOTIC EFFECT OF CYCLODEXTRIN INCLUSION COMPLEXES OF ECONAZOLE AND MICONAZOLE

The stability constants between beta-cyclodextrin (beta-CD) and the two antimycotic imidazole derivatives, miconazole and econazole were measured. Increased ionization of the imidazole derivatives decreased the size of the stability constants. The same phenomenon was observed for miconazole and hydroxypropyl-beta-cyclodextrin. In addition, the type of solubility diagram obtained was dependent on the degree of ionization of the imidazole derivatives. A type Bs solubility diagram was obtained for econazole and beta-CD in buffer solution, pH 7.1. An econazole beta-CD complex with a molar ratio of 1:1 was isolated. In a fluid medium the antimycotic effect of the econazole beta-CD complex against a strain of Candida albicans was superior to the effect of a physical mixture of the two compounds. A small inhibitory effect of beta-CD on the growth of the test organism was observed.

The first example of a diastereoselective thio-Ugi reaction: A new synthetic approach to chiral imidazole derivatives

The first example of a diastereoselective thio-Ugi reaction with chiral a-methylbenzylamine is described. The reaction results in formation of two diastereomers of thioamides, the major of which was isolated. We have found that under similar conditions stereochemical results of the thio-Ugi reaction are opposite to stereochemical results of the Ugi reaction. Several chiral thioamides were synthesized. The reaction of thioamides with ammonia results in substituted amidines, which can be cyclized to imidazole derivatives in aqueous HC1. The synthesis of chiral imidazole derivatives was elaborated. Using certain approaches, both isomers of a key synthon in the synthesis of SB203386 (an orally bioactive HIV-1 protease inhibitor) were prepared. The scope, limitations, and stereochemistry of the approach are discussed.

Atmospheric corrosion inhibitors for copper in the electronics industry

Inhibiting efficiencies of various imidazole derivatives on atmospheric corrosion of copper on printed circuit boards were investigated. Experiments were carried out on double sided copper boards using a procedure based on international standards and applied in the electronics industry.

Induction of cytochrome P4501A (CYPIA) by clotrimazole, a non-planar aromatic compound. Computational studies on structural features of clotrimazole and related imidazole derivatives

The classical pathway for induction of cytochrome P4501A (CYP1A) by xenobiotics is ligand binding to the aryl hydrocarbon receptor (AhR). High-affinity AhR ligands are planar polyaromatic molecules such as the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The present work investigated the ability of the imidazole derivative, clotrimazole [ 1-(2′ chlorotrityl)imidazole, CLO], to induce CYP1A in cultured rainbow trout (Oncorhynchus mykiss) hepatocytes at the catalytic activity (determined as 7-ethoxyresorufin-O-deethylase, EROD) and at the transcriptional level. CLO resulted in a significant increase of hepatocyte EROD activity and CYP1A mRNA at a concentration of 1.56 muM. Computational studies on the molecular structure of CLO show that CLO is unlikely to take a planar conformation. Further indications that CLO does not behave like a planar AhR ligand come from the experimental observation that co-incubation of trout hepatocytes with CLO and the AhR antagonist, alpha-naphthoflavone (alpha-NF), did not result in an inhibition of CLO induction of CYP1A mRNA, whereas alpha-NF was able to inhibit CYP1A induction by the prototpyic, planar AhR ligand, beta-naphthoflavone. The experimental findings on CLO agree with previous results obtained for another non-planar imidazole derivative, 1-benzylimidazole (B1M). Further, computational studies showed that the non-planar imidazoles, BIM and CLO, are highly similar with respect to some electrostatic properties, namely the dipole moment and the molecular electrostatic potential (MEP). Overall our experimental and computational studies suggest that transcriptional activation of CYP1A by the imidazole derivatives CLO and BIM is mediated by a mechanism different to that of prototypic CYP1A inducers such as the planar AhR-ligands.
