Alkyl piperidine and piperazine hydroxamic acids as HDAC inhibitors

We report here the strategy used in our research group to find a new class of histone deacetylase (HDAC) inhibitors. A series of N-substituted 4-alkylpiperazine and 4-alkylpiperidine hydroxamic acids, corresponding to the basic structure of HDAC inhibitors (zinc binding moiety-linker-capping group) has been designed, prepared, and tested for HDAC inhibition. Linker length and aromatic capping group connection were systematically varied to find the optimal geometric parameters. A new series of submicromolar inhibitors was thus identified, which showed antiproliferative activity on HCT-116 colon carcinoma cells.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 137076-22-3 is helpful to your research. Reference of 137076-22-3

A simple procedure for selective hydroxylation of L -proline and l -pipecolic acid with recombinantly expressed proline hydroxylases

Due to their diverse regio- and stereoselectivities, proline hydroxylases provide a straightforward access to hydroxprolines and other hydroxylated cylic amino acids, valuable chiral building blocks for chemical synthesis, which are often not available at reasonable expense by classical chemical synthesis. As yet, the application of proline hydroxylases is limited to a sophisticated industrial process for the production of two hydroxyproline isomers. This is mainly due to difficulties in their heterologues expression, their limited in vitro stability and complex product purification procedures. Here we describe a facile method for the production of cis-3-, cis-4- and trans-4-proline hydroxylase, and their application for the regio- and stereoselective hydroxylation of L-proline and its six-membered ring homologue l-pipecolic acid. Since in vitro catalysis with these enzymes is not very efficient and conversions are restricted to the milligram scale, an in vivo procedure was established, which allowed a quantitative conversion of 6 mM l-proline in shake flask cultures. After facile product purification via ion exchange chromatography, hydroxyprolines were isolated in yields of 35-61% (175-305 mg per flask). L-Pipecolic acid was converted with the isolated enzymes to prove the selectivities of the reactions. In transformations with optimized iron(II) concentration, conversions of 17-68% to hydroxylated products were achieved. The regio- and stereochemistry of the products was determined by NMR techniques. To demonstrate the applicability of the preparative in vivo approach for non-physiological substrates, L-pipecolic acid was converted with an E. coli strain producing trans-4-proline hydroxylase to trans-5-hydroxy-L-pipecolic acid in 61% yield. Thus, a synthetically valuable group of biocatalysts was made readily accessible for application in the laboratory without a need for special equipment or considerable development effort.

Design and synthesis of a novel series of histamine H3 receptor antagonists through a scaffold hopping strategy

Lead compounds 5-fluoro-2-methyl-N-[2-methyl-4-(2-methyl-[1,3?]bipyrrolidinyl-1?-yl)-phenyl]-benzamide (1), tetrahydro-pyran-4-carboxylic acid [((2S,3?S)-2-methyl-[1,3?]bipyrrolidinyl-1?-yl)-phenyl]-amide (2), and 3,5-dimethyl-isoxazole-4-carboxylic acid [((2S,3?S)-2-methyl-[1,3?]bipyrrolidinyl-1?-yl)-phenyl]-amide (3) discovered in our laboratory, displayed high histamine H3 receptor (H3R) affinity, good selectivity and weak human Ether–go-go-Related Gene (hERG) channel affinity with desirable overall physico-chemical and pharmacokinetic (PK) profiles. Herein, we describe the design and synthesis of a novel series of H3R antagonists utilizing a scaffold hopping strategy. Further structure-activity relationship (SAR) studies of the series culminated in the identification of ((2S,3?S)-2-methyl-[1,3?]bipyrrolidinyl-1?-yl)-naphthalene-2-carboxylic acid (tetrahydro-pyran-4-yl)-amide (4c) and -[4-((2S,3?S)-2-methyl-[1,3?]bipyrrolidinyl-1?-yl)-phenyl]-N-(tetrahydro-pyran-4-yl)-acetamide (4d), which exhibited good H3R affinity in vitro, good selectivity, and desirable PK properties. Compounds 4c and 4d were also assessed in cardiac safety experiments. In particular, the effects of the compounds on action potentials recorded from ventricular myocytes isolated from guinea pigs were used to screen compounds that not only displayed a low affinity towards hERG channel, but also had lower interference with other cardiac ion channels. Compound 4c did not alter the major parameters in this model system at ?10 muM, and no significant induction of any major haemodynamic effect when intravenously administered at 3 mg/kg dose to anaesthetized mongrel dogs. Compound 4c is a new promising lead as orally potent and selective H3R antagonist belonging to a distinct structural class.

Structure-activity relationship studies of novel 4-[2-[bis(4- fluorophenyl)methoxy]ethyl]-1-(3-phenylpropyl)piperidine analogs: Synthesis and biological evaluation at the dopamine and serotonin transporter sites

Several analogs of the potent dopamine (DA) transporter ligand 4-[2- [bis(4-fluorophenyl)-methoxy]ethyl]-1-(3-phenylpropyl)piperidine, 1b, were made and biologically evaluated for their binding at the DA and serotonin (5HT) transporters in rat striatal membranes. Different alkyl chain lengths and substitutions were introduced in these molecules to generate an optimum activity and selectivity for the DA transporter. In general, unsubstituted and fluoro-substituted compounds were the most active and selective for the DA transporter. The compound 4-[2(diphenylmethoxy)ethyl]-1-benzylpiperidine, 9a, showed high potency and was the most selective for the DA transporter (5HT/DA = 49) in this series of compounds. Some of these novel analogs were found to be more selective in binding at the DA transporter than the original GBR 12909 molecule, 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3- phenylpropyl)piperidine.

Identification, characterization and pharmacological profile of three metabolites of (R)-(+)-1,2,3,6-tetrahydro-4-phenyl-1-[(3-phenylcyclohexen-1- yl)methyl]pyridine (CI-1007), a dopamine autoreceptor agonist and potential antipsychotic agent

Liquid chromatographic-mass spectrometric (LC-MS) analysis of plasma taken from cynomolgus monkeys dosed orally with (R)-(+)-1,2,3,6-tetrahydro-4- phenyl-1-[(3-phenylcyclohexen-1-yl)methyl]pyridine (1), a dopamine (DA) autoreceptor agonist and potential antipsychotic agent, revealed several metabolites. The molecular masses of three major metabolites suggested that they were mono- and dihydroxylated derivatives of 1. We synthesized compounds 2 and 3, the two possible mono-p-hydroxyphenyl derivatives of 1, along with the bis-p-hydroxyphenyl derivative 4. These compounds coeluted by HPLC with the three hydroxylated metabolites of 1. Compounds 2-4 all had high affinities for DA D2 and D3 receptors and moderate affinities for D4 receptors. Like 1, compound 2 decreased DA synthesis and neuronal firing in rat brain, indicative of DA autoreceptor activation. Compound 2 inhibited exploratory locomotor activity in rodents and was active in the Sidman avoidance test in squirrel monkeys, predictive of antipsychotic activity in humans. Compounds 3 and 4 showed weak activity in all these tests. After squirrel monkeys were dosed with 1 orally at the ED100 dose of the Sidman avoidance test, the plasma concentration of 2 was below the limit of quantitation. Therefore, these metabolites are unlikely to contribute greatly to the potent activity seen with 1 in the Sidman avoidance test.

Bioactive Benzofuran derivatives: A review

In nature’s collection of biologically active heterocycles, benzofuran derivatives constitute a major group. The broad spectrum of pharmacological activity in individual benzofurans indicates that this series of compounds is of an undoubted interest. Benzofuran and its derivatives have attracted medicinal chemists and pharmacologists due to their pronounced biological activities and their potential applications as pharmacological agents. Due to the wide range of biological activities of benzofurans, their structure activity relationships have generated interest among medicinal chemists, and this has culminated in the discovery of several lead molecules in numerous disease conditions. The outstanding development of benzofuran derivatives in diverse diseases in very short span of time proves its magnitude for medicinal chemistry research. The present review is endeavour to highlight the progress in the various pharmacological activities of benzofuran derivatives in the current literature with an update of recent research findings on this nucleus.
