The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about gem-Bisphosphonate-Ended Group Dendrimers: Design and Gadolinium Complexing Properties, the main research direction is gem bisphosphonate terminated dendrimer gadolinium complex magnetic property; piperazino gem bisphosphonate functionalized gadolinium complex crystal structure.Safety of 4-(Piperazin-1-yl)phenol.

The synthesis of the first gem-bisphosphonate-ended group dendrimers is described using nucleophilic substitution of terminal P(S)Cl2 units of phosphorus dendrimers of generation 1 to 3 with protected aminophenols followed by deprotection of amino groups and Michael addition with vinylidene tetraisopropyl bisphosphonate. These dendrimers were found to act as chelating agents towards Gd ions. Contrary to the phosphonic acids that can introduce bridges between Gd ions, these synthons act as unique chelating agents toward the Gd ions. Furthermore, it appears that the number of Gd ions introduced in the isolated units is equal to the number of gem-bisphosphonate pairs. Eventually, the magnetic measurements demonstrate clearly that the Gd ions are not coordinated to these pairs as isolated ions but that at least some of these ions are bridged through oxygen atoms that are not P=O functions, as shown by the structural determination given in the paper. Studies concerning properties of these Gd dendrimers complexes are under active study. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009).

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Comparative metabolic disposition of oral doses of omeprazole in the dog, rat, and mouse.Category: ethers-buliding-blocks.

The metabolic disposition of 14C-labeled omeprazole  [73590-58-6] was studied in dogs, rats, and mice after the administration of pharmacol. active, single oral doses of drug in buffer solutions (pH 9). Averages of 38% (dogs), 43% (rats), and 55% (mice) of the radiolabeled doses were excreted in the urine in 72 h. Most of the remaining dose was recovered in the feces. Omeprazole was extensively metabolized in all species studied and the metabolites were eliminated rapidly. No unchanged drug could be detected in the urine samples (<0.1% of dose). In each species at least 10 metabolites were detected in urine (pH 9) by gradient elution reverse phase HPLC. Based on liquid chromatog. retention data, the metabolic patterns were very complex and exhibited some quant. differences between species. Bile was collected from rats and from chronic bile-fistulated dogs. Biliary excretion was a major route of elimination of omeprazole metabolites, and four polar metabolites were detected in the rat bile. The stability of omeprazole metabolites at varying pH values is discussed with reference to reductive metabolism of the parent compound There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC)Category: ethers-buliding-blocks, and with the development of science, more effects of this compound(73590-85-9) can be discovered.

Production of enantiopure esomeprazole by biocatalysis is of great demand by pharmaceutical industry. A Gram-pos. bacterium oxidizing omeprazole sulfide (5-methoxy-2-[((4-methoxy-3,5-dimethylpyridin-2-yl)methyl)thio]-1H-benzoimidazole) to (S)-sulfoxide esomeprazole (S)-5-methoxy-2-[(4-methoxy-3,5-dimethylpyridin-2-yl) methylsulfinyl]-3H-benzoimidazole was isolated from soil polluted with elemental sulfur. The strain exhibited the highest identity with the genus Lysinibacillus and catalyzed oxidation of 1a into enantiopure esomeprazole with conversion of 77% in a stirred bioreactor, fed-batch culture. No consecutive oxidation of (S)-sulfoxide to sulfone was observed during whole-cell catalysis. The unique characteristics of the catalyst provide a solid basis for further improvement and development of sustainable green bioprocess.

A highly efficient synthesis of esomeprazole – the (S)-enantiomer of omeprazole – via asym. oxidation of prochiral sulfide I is described. The asym. oxidation was achieved by titanium-mediated oxidation with cumene hydroperoxide (CHP) in the presence of (S,S)-diethyl tartrate [(S,S)-DET]. The enantioselectivity was provided by preparing the titanium complex in the presence of I at an elevated temperature and/or during a prolonged preparation time and by performing the oxidation of I in the presence of an amine. An enantioselectivity of >94% ee was obtained using this method.

A delicate balance exists between a drug mol.’s toxicity and its activity. Indeed, efficacy, toxicity, and side effect problems are a common cause for the termination of drug candidate compounds and development projects. To address this, an antitarget interaction profile is built and combined with virtual screening and cross docking for new inhibitors of HIV-1 integrase, in order to consider possible off-target interactions as early as possible in a drug or hit discovery program. New ranking techniques using triangular numbers improve ranking information on the compounds and recovery of known inhibitors into the top compounds using different docking programs. This improved ranking arises from using consensus of ranks between docking programs and ligand efficiencies to derive a new rank, instead of using absolute score values, or average of ranks. The triangular number rerank also allowed the objective combination of results from several protein targets or screen conditions and several programs. Triangular number reranking conserves more information than other reranking methods such as average of scores or averages of ranks. In addition, the use of triangular numbers for reranking makes possible the use of thresholds with a justified leeway based on the number of available known inhibitors, so that the majority of the compounds above the threshold in ranks compare to the compounds that have known exptl. determined biol. activity. The battery of anti- or off-targets can be tailored to specific mol. or drug design challenges. In silico filters can thus be deployed in successive stages, for prefiltering, activity profiling, and for further anal. and triaging of libraries of compounds

Tyrosinase (TYR, EC 1.14.18.1) plays a pivotal role in mammalian melanogenesis and enzymic browning of plant-derived food. Therefore, tyrosinase inhibitors (TYRIs) can be of interest in cosmetics and pharmaceutical industries as depigmentation compounds as well as anti-browning agents. Starting from 4-benzylpiperidine derivatives that showed good inhibitory properties toward tyrosinase from Agaricus bisporus (TyM), we synthesized a new series of TYRIs named 3-(4-benzyl-1-piperidyl)-1-(4-phenylpiperazin-1-yl)propan-1-one and 2-(4-benzyl-1-piperidyl)-1-(4-phenylpiperazin-1-yl)ethanone derivatives Among them, compound 4b proved to be the most potent inhibitor (IC50 = 3.80μM) and it also showed a good antioxidant activity. These new data furnished addnl. information about the SAR for this class of TYRIs.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:56621-48-8) here.

In this work series new theobromines, compounds I [R = benzyl, 4-hydroxyphenyl, bis(4-fluorophenyl)methyl, etc.; n = 3,4] with established antioxidant and antiproliferative activities were evaluated for their hepatotoxic effects on cellular and sub-cellular level. On isolated rat hepatocytes, compounds I [R = 4-hydroxyphenyl, n = 3,4] expressed lowest toxicity, while compounds I [R = bis(4-fluorophenyl)methyl, n = 3,4] showed highest toxicity. Compounds I [R = bis(4-fluorophenyl)methyl, n = 3,4] showed the most evident pro-oxidant effect in a lipid peroxidation model on rat liver microsomes, followed by compounds I [R = 4-fluorophenyl, n = 3,4], while the other compounds didn’t reveal statistically significant pro-oxidant effects. The performed quant. structure-toxicity relationship (QSTR) anal. show that increased lipophilicity of the tested compounds pos. correlates to their hepatotoxicity. Opposite, the presence in the structure of highly pos. H-atoms and strongly neg. oxygen, possibly originating from hydrogen bond donor groups, are associated with reduced hepatotoxicity.
