Synthetic lethal screening is a chem. biol. approach to identify small mols. that selectively kill oncogene-expressing cell lines with the goal of identifying pathways that provide specific targets against cancer cells. We performed a high-throughput screen of 303,282 compounds from the National Institutes of Health-Mol. Libraries Small Mol. Repository (NIH-MLSMR) against immortalized BJ fibroblasts expressing HRASG12V followed by a counterscreen of lethal compounds in a series of isogenic cells lacking the HRASG12V oncogene. This effort led to the identification of two novel mol. probes (PubChem CID 3689413, ML162 and CID 49766530, ML210) with nanomolar potencies and 4-23-fold selectivities, which can potentially be used for identifying oncogene-specific pathways and targets in cancer cells.

Safety of 1-(Bis(4-chlorophenyl)methyl)piperazine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Development and validation of an in silico P450 profiler based on pharmacophore models. Author is Schuster, Daniela; Laggner, Christian; Steindl, Theodora M.; Langer, Thierry.

In today’s drug discovery process, the very early consideration of ADME properties is aimed at a reduction of drug candidate drop out rate in later development stages. A part from in vitro testing, in silico methods are evaluated as complementary screening tools for compounds with unfavorable ADME attributes. Especially members of the cytochrome P 450 (P 450) enzyme superfamily. e.g. P 450 1A2, P 450 2C9, P 450 2C19, P 450 2D6, and P 450 3A4, contribute to xenobiotic metabolism, and compound interaction with one of these enzymes is therefore critically evaluated. Pharmacophore models are widely used to identify common features amongst ligands for any target. In this study, both structure-based and ligand-based models for prominent drug-metabolizing members of the P 450 family were generated employing the software packages LigandScout and Catalyst. Essential chem. ligand features for substrate and inhibitor activity for all five P 450 enzymes investigated were determined and analyzed. Finally, a collection of 11 pharmacophores for substrates and inhibitors was evaluated as an in silico P 450 profiling tool that could be used for early ADME estimation of new chem. entities.

Eaton, John K.; Furst, Laura; Cai, Luke L.; Viswanathan, Vasanthi S.; Schreiber, Stuart L. published the article 《Structure-activity relationships of GPX4 inhibitor warheads》. Keywords: structure preparation GPX4 inhibitor propiolamide NO warhead; Covalent inhibitors; Ferroptosis; GPX4; Masked electrophiles.They researched the compound: 1-(Bis(4-chlorophenyl)methyl)piperazine( cas:27469-61-0 ).Application of 27469-61-0. 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:27469-61-0) here.

Direct inhibition of GPX4 requires covalent modification of the active-site selenocysteine. While phenotypic screening has revealed that activated alkyl chlorides and masked nitrile oxides can inhibit GPX4 covalently, a systematic assessment of potential electrophilic warheads with the capacity to inhibit cellular GPX4 has been lacking. Here, we survey more than 25 electrophilic warheads across several distinct GPX4-targeting scaffolds. We find that electrophiles with attenuated reactivity compared to chloroacetamides are unable to inhibit GPX4 despite the expected nucleophilicity of the selenocysteine residue. However, highly reactive propiolamides we uncover in this study can substitute for chloroacetamide and nitroisoxazole warheads in GPX4 inhibitors. Our observations suggest that electrophile masking strategies, including those we describe for propiolamide- and nitrile-oxide-based warheads, may be promising for the development of improved covalent GPX4 inhibitors.

Name: 1-(Bis(4-chlorophenyl)methyl)piperazine. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Synthesis and antiallergic activities of diphenylmethylpiperazine derivatives. Author is Wang, Lisheng; Jiang, Hongyu; Zhou, Yonghong; Liu, Baili; Ji, Zhizhong.

The diphenylmethylpiperazine derivatives were designed and synthesized to find high anti-allergic compounds Twenty-one compounds of 1-R3-4-[(4-R1-phenyl)(4-R2-phenyl)methyl]piperazine (R1 = H, Cl, F, methoxy, tert-Bu, or nitro; R2 = H, F, Cl, or tert-butyl; and R3 = Et, benzyl, Bu, octyl, cetyl, or dodecyl), among which 17 compounds were new ones, were designed and synthesized from benzophenone derivatives by reduction with Zn/NaOH, substitution reaction with piperazine, and substitution reaction with R3Br. Their structures were identified by IR, 1H-NMR spectral, and elemental anal. Some compounds were evaluated from two pharmacol. models of the delayed-type hypersensitivity response to 2,4-dinitrochlorobenzene (DNCB) in mice and vascular permeability reduced by histamine in mice. Two compounds (R1 = R2 = H and R3 = Bu or dodecyl) had high antiallergic effects on the delayed-type hypersensitivity, and 5 compounds (R1 = R2 = H, R3 = octyl, cetyl, or dodecyl; R1 = nitro or F, R2 = H or F, R3 = dodecyl) had high antihistamine activity. Antiallergic activity was stronger with longer carbon chains.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Proteome-Wide Reactivity Profiling Identifies Diverse Carbamate Chemotypes Tuned for Serine Hydrolase Inhibition, the main research direction is proteomewide reactivity profiling carbamate serine hydrolase monacylglyserol lipase.SDS of cas: 27469-61-0.

Serine hydrolases are one of the largest and most diverse enzyme classes in Nature. Inhibitors of serine hydrolases are used to treat many diseases, including obesity, diabetes, cognitive dementia, and bacterial and viral infections. Nonetheless, the majority of the 200+ serine hydrolases in mammals still lack selective inhibitors for their functional characterization. We and others have shown that activated carbamates, through covalent reaction with the conserved serine nucleophile of serine hydrolases, can serve as useful inhibitors for members of this enzyme family. The extent to which carbamates, however, cross-react with other protein classes remains mostly unexplored. Here, we address this problem by investigating the proteome-wide reactivity of a diverse set of activated carbamates in vitro and in vivo, using a combination of competitive and click chem. (CC)-activity-based protein profiling (ABPP). We identify multiple classes of carbamates, including O-aryl, O-hexafluoroisopropyl (HFIP), and O-N-hydroxysuccinimidyl (NHS) carbamates that react selectively with serine hydrolases across entire mouse tissue proteomes in vivo. We exploit the proteome-wide specificity of HFIP carbamates to create in situ imaging probes for the endocannabinoid hydrolases monoacylglycerol lipase (MAGL) and α-β hydrolase-6 (ABHD6). These findings, taken together, designate the carbamate as a privileged reactive group for serine hydrolases that can accommodate diverse structural modifications to produce inhibitors that display exceptional potency and selectivity across the mammalian proteome.
