Loutrel, Nicholas published the artcileSecond-order perturbations of Kerr black holes: Formalism and reconstruction of the first-order metric, Name: 4-Methoxyphenylacetic acid, the main research area is black holes gravitational wave perturbations quasi reconstruction.

Motivated by gravitational wave observations of binary black hole mergers, we present a procedure to compute the leading-order nonlinear gravitational wave interactions around a Kerr black hole. We describe the formalism used to derive the equations for second-order perturbations. We develop a procedure that allows us to reconstruct the first-order metric perturbation solely from knowledge of the solution to the first-order Teukolsky equation, without the need of Hertz potentials. Finally, we illustrate this metric reconstruction procedure in the asymptotic limit for the first-order quasinormal modes of Kerr. In a companion paper [J. L. Ripley et al., Phys. Rev. D103, 104018 (2021)PRVDAQ2470-001010.1103/PhysRevD.103.104018] we present a numerical implementation of these ideas.

Doering, Skye R. published the artcileDiscovery of Nanomolar Melanocortin-3 Receptor (MC3R)-Selective Small Molecule Pyrrolidine Bis-Cyclic Guanidine Agonist Compounds Via a High-Throughput “”Unbiased”” Screening Campaign, Computed Properties of 104-01-8, the main research area is energy balance MC3R MC4R melanocortin agonist guanidines body weight.

The central melanocortin-3 and melanocortin-4 receptors (MC3R, MC4R) are key regulators of body weight and energy homeostasis. Herein, the discovery and characterization of first-in-class small mol. melanocortin agonists with selectivity for the melanocortin-3 receptor over the melanocortin-4 receptor are reported. Identified via “”unbiased”” mixture-based high-throughput screening approaches, pharmacol. evaluation of these pyrrolidine bis-cyclic guanidines resulted in nanomolar agonist activity at the melanocortin-3 receptor. The pharmacol. profiles at the remaining melanocortin receptor subtypes tested indicated similar agonist potencies at both the melanocortin-1 and melanocortin-5 receptors and antagonist or micromolar agonist activities at the melanocortin-4 receptor. This group of small mols. represents a new area of chem. space for the melanocortin receptors with mixed receptor pharmacol. profiles that may serve as novel lead compounds to modulate states of dysregulated energy balance.

Mirabile, Salvatore published the artcileEvaluation of 4-(4-Fluorobenzyl)piperazin-1-yl]-Based Compounds as Competitive Tyrosinase Inhibitors Endowed with Antimelanogenic Effects, Formula: C9H10O3, the main research area is fluorobenzylpiperazinyl derivative tyrosinase inhibitor antimelanogenic; Docking studies; Homology model; Kinetic mechanism; Synthesis; Tyrosinase inhibitors.

There is a considerable attention for the development of inhibitors of tyrosinase (TYR) as therapeutic strategy for the treatment of hyperpigmentation disorders in humans. Continuing in our efforts to identify TYR inhibitors, we describe the design, synthesis and pharmacophore exploration of new small mols. structurally characterized by the presence of the 4-fluorobenzylpiperazine moiety as key pharmacophoric feature for the inhibition of TYR from Agaricus bisporus (AbTYR). Our investigations resulted in the discovery of the competitive inhibitor [4-(4-fluorobenzyl)piperazin-1-yl]-(3-chloro-2-nitro-phenyl)methanone 26 (I, IC50=0.18μM) that proved to be ∼100-fold more active than reference compound kojic acid (IC50=17.76μM). Notably, compound 26 exerted antimelanogenic effect on B16F10 cells in absence of cytotoxicity. Docking anal. suggested its binding mode into AbTYR and into modelled human TYR.

Musa, Musiliyu A. published the artcileIdentification of 7,8-dihydroxy-3-phenylcoumarin as a reversible monoamine oxidase enzyme inhibitor, Application of 4-Methoxyphenylacetic acid, the main research area is dihydroxy phenylcoumarin monoamine oxidase enzyme inhibitor neuroprotection; 3-arylcoumarin; molecular modeling; monoamine oxidase inhibitors; neuroprotection; structure-activity relationship.

We herein report the biol. evaluation of 3-arylcoumarin derivatives (3a-l) as potential human monoamine oxidase-A and -B (hMAO-A and hMAO-B) inhibitors. The result indicated that 7,8-dihydroxy-3-(4-nitrophenyl)coumarin (3j) was most effective against MAO-A (inhibition concentration [IC50] = 6.46 ± 0.02μM) and MAO-B (IC50 = 3.8 ± 0.3μM) enzymes than other synthesized compounds and reference compounds (pargyline and moclobemide). Furthermore, compound (3j) showed (a) nonselectivity against hMAO enzymes, (b) reversible hMAO enzymes inhibition, and (c) neuroprotection against H2O2-treated human neuroblastoma (N2a) cells. Finally, a mol. modeling study revealed that the hMAO enzymes inhibitory activity of the compound (3j) may be due to the orientation where the nitro (NO2) group lies deep into the receptor and the Ph ring directed toward flavin adenosine dinucleotide via hydrogen bond interaction, and possible π-π interaction with various important residues. Thus, the results of the present study demonstrate that compound (3j) can be considered as a promising scaffold for the development of hMAO-A and hMAO-B inhibitors.

Castillo-Luna, A. published the artcileThe secoiridoid profile of virgin olive oil conditions phenolic metabolism, Category: isoquinoline, the main research area is secoiridoid extra virgin olive oil phenolic metabolism; LC–MS/MS; Microbial metabolism; Olive oil; Phase I metabolism; Phase II metabolism; Secoiridoids.

The European Food Safety Authority highlights the beneficial effects of olive oil phenols, mainly, secoiridoids. Nevertheless, the metabolism of secoiridoids in humans has not been fully elucidated. This research evaluated the metabolism of secoiridoids in humans after intake of olive oils with diverse phenolic profiles. For this purpose, three extra virgin olive oils (EVOOs) were ingested by six volunteers at scheduled meals, and urine samples were collected the following morning for subsequent LC-MS/MS anal. Using untargeted anal., urinary metabolites revealed representative patterns associated with the various olive oil phenolic contents in absolute and relative terms. We were able to identify metabolites obtained through phase I, phase II, and microbial metabolism with discrimination between tyrosol and hydroxytyrosol derivatives Metabolism of phenols is differentially activated as a function of the olive oil secoiridoids content, and this proof-of-concept study shows how urinary metabolites represent olive oil phenolic content.

Kumar, Naresh published the artcileAnti-oxidation properties of 2-substituted furan derivatives: A mechanistic study, HPLC of Formula: 104-01-8, the main research area is furan derivative absorption antioxidant property.

2-(P-Ph substituted styryl)-furans were synthesized and studied the excited state and anti oxidation properties using absorption, fluorescence, d. functional theory and DPPH radical scavenging assay. 2-(P-hydroxy Ph styryl)-furan (6) exhibits good antioxidant properties with IC50 âˆ?40μM as compared to the amine, chloro, cyano methoxy and nitro substituted styryl compounds (1-5, 7-8) (IC50 > 150μM). It is shown that furans 1-3 with strong electron withdrawing nitro, cyano and chloro substituent do not show antioxidant properties. The O-H bond dissociation energy (BDE) of p-hydroxy substituted furan compound is comparable to the BDE of vitamin E. The antioxidant activity of furan compound is further reduced with increasing the dipolar nature of the mol. From the thermodn. parameters and antioxidant properties, it is shown that there is a correlation of antioxidant properties with the ground state dipole moment, X-H bond dissociation energy (X: O; N) and proton affinity (PA). In presence of the furan compound, the quenching of DPPH radical is occurred predominantly through hydrogen atom transfer mechanism.
