Author is Bhandare, Richie R.; Canney, Daniel J..

Lead lactone-based ligands with modest affinity for muscarinic receptors were modified based on structure-activity relationship data in the literature to provide a new series of 5-substituted 4,5-dihydro-2(3H)-furanones. The modifications included the addition of various nitrogen-containing heterocycles attached to substituted and unsubstituted aromatic rings. The target compounds, e.g. I, were synthesized in modest yields and evaluated in preliminary muscarinic binding assays. A lactone-based ligand containing a diphenylmethylpiperazine moiety was identified as a nonselective muscarinic ligand with IC50 of 340 nM. The design of future ligands will be based, in part, on structure-activity data reported herein.

Author is Moutzouri, Pinelopi; Kiraly, Peter; Phillips, Andrew R.; Coombes, Steven R.; Nilsson, Mathias; Morris, Gareth A..

A new NMR experiment (Destruction of Interfering Satellites by Perfect Echo Low-pass filtration, DISPEL) is introduced that facilitates the anal. of low-level components in high dynamic range mixtures by suppressing one-bond 13C satellite signals in 1H spectra. Since the natural abundance of 13C is around 1.1%, these satellites appear at 0.54% of the intensity of a parent peak, mimicking and often masking impurity signals. The new experiment suppresses one-bond 13C satellite signals, with high efficiency, at negligible cost in signal-to-noise ratio, and over a wide range of one-bond coupling constants, without the need for broadband 13C decoupling.

The ERCC1-XPF heterodimer is a 5′-3′ structure-specific endonuclease, which plays an essential role in several DNA repair pathways in mammalian cells. ERCC1-XPF is primarily involved in the repair of chem. induced helix-distorting and bulky DNA lesions, such as cyclobutane pyrimidine dimers (CPDs), and DNA interstrand cross-links. Inhibition of ERCC1-XPF has been shown to potentiate cytotoxicity of platinum-based drugs and cyclophosphamide in cancer cells. In this study, the previously described ERCC1-XPF inhibitor 4-((6-chloro-2-methoxyacridin-9-yl)amino)-2-((4-methylpiperazin-1-yl)methyl)phenol (compound 1) was used as a reference compound Following the outcome of docking-based virtual screening (VS), we synthesized seven novel derivatives of 1 that were identified in silico as being likely to have high binding affinity for the ERCC1-XPF heterodimerization interface by interacting with the XPF double helix-hairpin-helix (HhH2) domain. Two of the new compounds, 4-((6-chloro-2-methoxyacridin-9-yl)amino)-2-((4-cyclohexylpiperazin-1-yl)methyl)phenol (compound 3) and 4-((6-chloro-2-methoxyacridin-9-yl)amino)-2-((4-(2-(dimethylamino)ethyl) piperazin-1-yl) methyl) phenol (compound 4), were shown to be potent inhibitors of ERCC1-XPF activity in vitro. Compound 4 showed significant inhibition of the removal of CPDs in UV-irradiated cells and the capacity to sensitize colorectal cancer cells to UV radiation and cyclophosphamide.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 56621-48-8, is researched, Molecular C10H14N2O, about Ordered Layered Dendrimers Constructed from Two Known Dendrimer Families: Inheritance and Emergence of Properties, the main research direction is triazine piperazine dendrimer; dendrimers; electrochemistry; phosphorus; piperazine; triazines.Category: ethers-buliding-blocks.

A new concept is presented, namely the synthesis of dendrimers intrinsically composed in alternation of building blocks pertaining to two known families of dendrimers: phosphorhydrazone dendrimers and triazine-piperazine dendrimers. These mixed dendrimers with layered controlled architecture inherit their easy 31P NMR characterization and their thermal stability from the phosphorhydrazone family, and their decreased solubility from the triazine-piperazine family. However, they have also their own and original characteristics. Both parent families are white powders, whereas the mixed dendrimers are yellow, orange, or red powders, depending on the generation. DFT calculations were carried out on model dendrons to understand these special color features. Remarkably, these dendrimers incorporating redox-active organic entities allow for the first time the monitoring of the growth of an organic dendrimer by electrochem. while highlighting an even-odd generation behavior.

Name: 4-(Piperazin-1-yl)phenol. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Structure-Function Analysis of Phenylpiperazine Derivatives as Intestinal Permeation Enhancers. Author is Fein, Katherine C.; Lamson, Nicholas G.; Whitehead, Kathryn A..

Purpose: A major obstacle preventing oral administration of macromol. therapeutics is poor absorption across the intestinal epithelium into the bloodstream. One strategy to improve transport across this barrier is the use of chem. permeation enhancers. Several mol. families with permeation enhancing potential have been identified previously, including piperazines. In particular, 1-phenylpiperazine has been shown to enhance transepithelial transport with minimal cytotoxicity compared to similarly effective mols. To better understand how the chem. of 1-phenylpiperazine affects its utility as an intestinal permeation enhancer, this study examined a small library of 13 derivatives of 1-phenylpiperazine. Methods: The efficacy and cytotoxicity of 13 phenylpiperazine compounds were assessed in a Caco-2 model of the intestinal epithelium. Efficacy was measured using the paracellular diffusion marker calcein as well as by immunostaining and confocal imaging of Caco-2 monolayers. Results: Of the 13 derivatives, two enhanced the permeability of the fluorescent marker calcein over 100-fold. It was found that hydroxyl or primary amine substitutions on the Ph ring significantly increased toxicity, while aliphatic substitutions resulted in efficacy and toxicity profiles comparable to 1-phenylpiperazine. Conclusions: Several potent derivatives, including 1-methyl-4-phenylpiperazine and 1-(4-methylphenyl)piperazine, displayed lower toxicity than 1-phenylpiperazine, suggesting promise in future applications.

After consulting a lot of data, we found that this compound(56621-48-8)Name: 4-(Piperazin-1-yl)phenol can be used in many types of reactions. And in most cases, this compound has more advantages.
