Synthesis and antimicrobial activity of benzazolyl azolyl urea derivatives

A new class of benzazolyl azolyl urea derivatives were prepared by the reaction of methyl benzazoyl carbamates with azolyl amines in the presence of mild base potassium tert-butoxide. The presence of electron withdrawing substituents on the aromatic ring enhanced the activity. Nitro substituted benzothiazolyl thiazolyl urea, benzothiazolyl imidazolyl urea and benzimidazolyl thiazolyl urea exhibited potential antibacterial activity against Bacillus subtilis. The compound benzothiazolyl imidazolyl urea and nitro substituted benzimidazolyl imidazolyl urea showed potential antifungal activity against Aspergillus niger.

AN INVESTIGATION OF THE TRANSMISSION OF ELECTRONIC EFFECTS IN A SERIES OF 5- AND 6-SUBSTITUTED BENZAZOLES BY THE METHODS OF BASIC DEUTERIUM EXCHANGE AND NMR SPECTROSCOPY

The kinetics of deuterium exchange at the methyl groups in 5- and 6-substituted 2-methylbenzothiazoles, 6-substituted 2-methylbenzoxazoles, and 5-substituted 1,2-dimethylbenzimidazoles have been studied.A quantitative estimate of the influence of the substituents on the free energy of activation of deuterium exchange and on chemical shifts in the 1H, 13C, and 19F NMR spectra of the benzazoles investigated and of the substituted quinolines and naphtalenes used as standard systems has been made with the aid of correlation analysis.It has ben shown that the decrease in the transmission capacity of the benzazole nucleus in the transition state of the reaction as compared with the initial state is due to the influence of cross-conjugation effects disturbing the additive nature of the electronic interactions.The question of the probable structure of the transition state of the reaction is disussed.

Dehydrogenative and decarboxylative C-H alkynylation of heteroarenes catalyzed by Pd(II)-carbene complex

The direct alkynylation of heteroarenes was accomplished with easily prepared Pd(II) carbene complex (Pd Cat.) by two complementary strategies. Pd Cat. catalysed cross-dehydrogenative coupling of terminal alkynes with heteroarenes was achieved in the first method and decarboxylative coupling of aryl propiolic acids with heteroarenes was investigated in the second method. Both the methodologies tolerate a broad variety of heteroarenes that include benzoxazoles, benzothiazoles, imidazole and benzimidazoles.

Quantitative gas-solid reactions with ClCN and BrCN: Synthesis of cyanamides, cyanates, thiocyanates, and their derivatives

Gas-solid reaction techniques allow quantitative cyanations with ClCN and BrCN. Three primary and four secondary cyanamides, a cyanimide, four cyanates, and four thiocyanates were all prepared as solids in 100% yield from solid anilines, benzimidazoles, imides, phenolates, and thiolates, respectively. Intramolecular solid-state reactions of cyanated o-aminophenol and of cyanated hydrazides gave heterocyclic compounds. When comparable reactions were performed in solution the reported product yields were considerably less than 100% in all cases. The reasons for the success of the environmentally benign solid-state syntheses are discussed in terms of phase rebuilding, phase transformation, and crystal disintegration. Atomic force microscopy (AFM) of selected systems indicates the occurrence of long-range molecular movements which are governed by the crystal packing. This is evident from the obvious correlations between the molecular movements and the known crystal packing data. A new type of geometric surface feature, a rectangular and a rhombic depression which resembles a swimming-pool basin, was found in the cyanation of o-aminophenol and benzohydrazide.

Utility of Nitrogen Extrusion of Azido Complexes for the Synthesis of Nitriles, Benzoxazoles, and Benzisoxazoles

The utility of the nitrogen extrusion reaction of azido complexes, generated in situ from the corresponding aldehydes or ketones with TMSN3 in the presence of ZrCl4 or TfOH, has been described. These azido complexes could undergo three different pathways, depending on the substrates. First, azido methanolate complexes or imine diazonium ions could lead to benzisoxazole products via an intramolecular nucleophilic substitution. Second, imine diazonium ions could also undergo either the elimination of proton to provide nitrile products in good to excellent yields or an aryl migration, followed by an intramolecular nucleophilic addition, to give benzoxazole products in good yields.

Significant change of cytochrome P450s activities in patients with hepatocellular carcinoma

The lack of information concerning individual variation in drug-metabolizing enzymes is one of the most important obstacles for designing personalized medicine approaches for hepatocellular carcinoma (HCC) patients. To assess cytochrome P450 (CYP) in the metabolism of endogenous and exogenous molecules in an HCC setting, the activity changes of 10 major CYPs in microsomes from 105 normal and 102 HCC liver tissue samples were investigated. We found that CYP activity values expressed as intrinsic clearance (CLint) differed between HCC patients and control subjects. HCC patient samples showed increased CLint for CYP2C9, CYP2D6, and CYP2E1 compared to controls. Meanwhile, CYP1A2, CYP2C8, and CYP2C19 CLint values decreased and CYP2A6, CYP2B6, and CYP3A4/5 activity was unchanged relative to controls. For patients with HCC accompanied by fibrosis or cirrhosis, the same activity changes were seen for the CYP isoforms, except for CYP2D6 which had higher values in HCC patients with cirrhosis. Moreover, CYP2D6*10 (100C>T), CYP2C9*3 (42614 A>C), and CYP3A5*3 (6986A>G) polymorphisms had definite effects on enzyme activities. In the HCC group, the CLint of CYP2D6*10 mutant homozygote was decreased by 95% compared to wild-type samples, and the frequency of this homozygote was 2.8-fold lower than the controls. In conclusion, the activities of CYP isoforms were differentially affected in HCC patients. Genetic polymorphisms of some CYP enzymes, especially CYP2D6*10, could affect enzyme activity. CYP2D6*10 allelic frequency was significantly different between HCC patients and control subjects. These findings may be useful for personalizing the clinical treatment of HCC patients as well as predicting the risk of hepatocarcinogenesis.

Comparison of N,N?-diarylsquaramides and N,N?-diarylureas as antagonists of the CXCR2 chemokine receptor

N,N?-diarylsquaramides were prepared and evaluated as antagonists of CXCR2. The compounds were found to be potent and selective antagonists of CXCR2. Significant differences in SAR was observed relative to the previously described N,N?-diarylurea series. As was the case in the N,N?-diarylurea series, placing sulfonamide substituent adjacent to the acidic phenol significantly reduced the clearance in rat pharmacokinetic studies.

Benzothiazolyl ureas are low micromolar and uncompetitive inhibitors of 17Beta-HSD10 with implications to Alzheimer?s disease treatment

Human 17beta-hydroxysteroid dehydrogenase type 10 is a multifunctional protein involved in many enzymatic and structural processes within mitochondria. This enzyme was suggested to be involved in several neurological diseases, e.g., mental retardation, Parkinson?s disease, or Alzheimer?s disease, in which it was shown to interact with the amyloid-beta peptide. We prepared approximately 60 new compounds based on a benzothiazolyl scaffold and evaluated their inhibitory ability and mechanism of action. The most potent inhibitors contained 3-chloro and 4-hydroxy substitution on the phenyl ring moiety, a small substituent at position 6 on the benzothiazole moiety, and the two moieties were connected via a urea linker (4at, 4bb, and 4bg). These compounds exhibited IC50 values of 1?2 muM and showed an uncompetitive mechanism of action with respect to the substrate, acetoacetyl-CoA. These uncompetitive benzothiazolyl inhibitors of 17beta-hydroxysteroid dehydrogenase type 10 are promising compounds for potential drugs for neurodegenerative diseases that warrant further research and development.
