QSAR study for classes with a broad range of biological activity using electronegativity descriptors for OMO-UMO quantum states. Clotrimazole imidazole derivatives with antiftingal activity

The class of clotrimazole imidazole derivatives having a broad spectrum of antimycotic activity has been studied using fingerprint descriptors based on electronegativity, of the occupied molecular orbitals (OMO) and unoccupied molecular orbitals (UMO). The Hansch equation Kd = a(0) + a(I)X(I), where X, = OMO / UMO electronegativity allows us to identify the nature of the atoms involved in ligand (drug)-receptor interactions, as well as the nature of those interactions.

Syntheses of Symmetric and Unsymmetric Bis-imidazole Derivatives Using Phase-Transfer Catalysis

A convenient method for the preparation of symmetric and unsymmetric bisimidazole derivatives was established. The symmetric bisimidazolylmethane derivatives 1a-9a was prepared with 2-substituted imidazole derivatives 1-9 as reaction materials. However, the symmetric and unsymmetric bisimidazolylmethane derivatives 10a-12a and 10b-12b was obtained, respectively. With 4-position with the azo-groups imidazole derivatives 10-12 were used as reaction materials. All these compounds have been structurally characterized by the NMR, ESI-MS, and EA. And 8a and 12a were also characterized by the X-ray single crystal diffusion.

Markovnikov addition of imidazole derivatives with vinyl esters catalyzed by lipase TL IM from Thermomyces lanuginosus/K2CO3 in a continuous-flow microreactor

In this work, a simple and efficient method for Markovnikov addition of imidazole derivatives to vinyl esters catalyzed by Lipozyme TL IM/K2CO3 in a continuous-flow microreactor was described. The effects of the mixed catalysts, molar ratio and the structure of reactants on the reaction performance were experimentally studied. The attractive features of this process are shorter reaction times (30 min) and excellent yields compared to that in shaker reactors.

Identification of furo[3 ‘,2 ‘:3,4]naphtho[1,2-d]imidazole derivatives as orally active and selective inhibitors of microsomal prostaglandin E-2 synthase-1 (mPGES-1)

This study describes the synthesis and anti-inflammatory effects of furo[3′, 2′:3,4]naphtho[1,2-d] imidazole derivatives. Among these furo[3′, 2′:3,4]naphtho[1,2-d]imidazole derivatives, 2-(4-methoxyphenyl)furo [3′, 2’:3,4]naphtho[1,2-d]imidazole (12) exhibited a strong inhibitory activity against LPS-induced PGE(2) production, with an IC50 value of 47 nM. Compound 12 is then further examined for its inhibitory effects in the protein expression of COX-2 and microsomal prostaglandin E-2 synthase-1 (mPGES-1) in Raw 264.7 cells. Our results indicate that compound 12 was capable against inhibiting LPS-induced mPGES-1 protein expression at a concentration of 1.0 mu M and no inhibitory effect in COX-2 expression. The sepsis-induced PGE(2) production in rat serum decreased similar to 250% by the pretreatment of 12 at 10 mg/kg. These results are especially important since compound 12 exhibited good oral bioavailability (72%) and was not cytotoxic at a concentration of 10.0 mu M. Therefore, compound 12 is a highly selective mPGES-1 inhibitor that can serve as a lead for the development of novel oral anti-inflammatory drug candidates.

Synthesis, characterization, and electrochemical properties of imidazole derivatives functionalized single-walled carbon nanotubes

The imidazole derivatives functionalized single-walled carbon nanotubes (SWNTs) were synthesized by a diazonium-based reaction. We have designed and synthesized two imidazole derivatives to modify SWNTs. The resulting products were characterized by Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, ultraviolet visible (UV/Vis) spectroscopy, thermo gravimetric analysis (TGA), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and atomic force microscopy (AFM). Electrochemical measurements via a cyclic voltammetry method revealed that the weak intramolecular electronic interactions presented between the attached imidazole derivatives groups and the nanotubes.

Imidazole derivatives as thermal latent catalyst for thiol-michael reaction thermosetting resins

Imidazole is an excellent nucleophilic initiator in thiol-Michael addition reaction of thiol and vinyl sulfone at room temperature. To delay the gelation of the monomer mixture, thermal latent curing agents based on imidazole are designed and the latency and curing efficiency towards thiol-vinyl sulfone system are evaluated. Ncarbonylated imidazole derivatives are non-nucleophilic towards Michael reaction with vinyl sulfone. However, during curing at elevated temperature ( > 80 degrees C), thiol monomer thiolyze imidazole derivative and the released imidazole acts as a nucleophilic initiator. It is found that the viscosity at room temperature of thiol-vinyl sulfone system with 2b or 2d imidazole derivatives increases slowly up to over 10 h, which permits sufficient time for processing such as mixing, degassing and injection into the mold. In the application of 2b or 2d in network polymerization of polythiol and divinyl sulfone, both catalysts have excellent curing ability with a 98% and 95% thiol conversion, respectively within 7 h at 100 degrees C. Using 2b or 2d, transparent thiol-vinyl sulfone resins with a refractive index of 1.57 and an Abbe number of 47.78 are successfully produced.

Selective Synthesis of Tetrasubstituted 4-(Tetrazol-5-yl)-1H-imidazoles from 2-(Tetrazol-5-yl)-2H-azirines

The reactivity of 2-(tetrazol-5-yl)-2H-azirines towards imines in the presence of Lewis acids was explored, which opened a way to new tetrazol-5-yl-1H-imidazole derivatives.
