In a patnet, author is Gerisch, Michael, once mentioned the new application about 39156-41-7.

Mass balance and biotransformation of finerenone, a nonsteroidal mineralocorticoid receptor antagonist, were investigated in four healthy male volunteers following a single oral administration of 10 mg (78 mu Ci) of [C-14]finerenone and compared with data from studies in dogs and rats. The total recovery of the administered radioactivity was 101% in humans, 94.7% in dogs, and 95.2% in rats. In humans, radioactivity was mainly excreted renally (80%); in rats, it was primarily the biliary/fecal route (76%); and in dogs, excretion was more balanced. Finerenone was extensively metabolized in all species by oxidative biotransformation, with minor amounts of unchanged drug in excreta (humans: 1%; dogs, rats: <9%). In vitro studies suggested cytochrome P450 3A4 was the predominant enzyme involved in finerenone metabolism in humans. Primary metabolic transformation involved aromatization of the dihydronaphthyridine moiety of metabolite M1 as a major clearance pathway with a second oxidative pathway leading to M4. These were both prone to further oxidative biotransformation reactions. Naphthyridine metabolites (M1-M3) were the dominant metabolites identified in human plasma, with no on-target pharmacological activity. In dog plasma, finerenone and metabolite M2 constituted the major components; finerenone accounted almost exclusively for drug-related material in rat plasma. For metabolites M1-M3, axial chirality was observed, represented by two atropisomers (e.g., M1a and M1b). Analysis of plasma and excreta showed one atropisomer (a-series, >79%) of each metabolite predominated in all three species. In summary, the present study demonstrates that finerenone is cleared by oxidative biotransformation, mainly via naphthyridine derivatives.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 39156-41-7. Recommanded Product: 4-Methoxybenzene-1,3-diamine sulfate.

With the ever-increasing concerns on environmental pollution and energy crisis, it is of great urgency to develop high-performance photocatalyst to eliminate organic pollutants from wastewater and produce hydrogen via water splitting. Herein, a polypyridyl-based mixed covalent Cu-I/II complex with triangular {Cu-3} and rhombic {Cu2Cl4} subunits alternately extended by mixed SCN- and Cl- heterobridges [Cu-4(DNP)(SCN)Cl-4](n) (1) [DNP = 2,6-bis(1,8-naphthyridine-2-yl)pyridine] was solvothermally synthesized and employed as a dual-functional co-photocatalyst. Resulting from a narrowed band-gap of 1.07 eV with suitable redox potential and unsaturated Cu-I/II sites, the complex together with H2O2 can effectively degrade Rhodamine B and methyl orange up to 87.4 and 88.2%, respectively. Meanwhile, the complex mixed with H2PtCl6 can also accelerate the photocatalytic water splitting in the absence of a photosensitizer with the hydrogen production rate of 27.5 mu mol.g(-1).h(-1). These interesting findings may provide informative hints for the design of the multiple responsive photocatalysts.

Spectroscopic investigations on DNA binding profile of two new naphthyridine carboxamides and their application as turn-on fluorescent DNA staining probes

Two new 10-methoxydibenzo[b,h][1,6]naphthyridine-2-carboxamide derivatives (R1 and R2) have been synthesized and characterized using different spectral techniques. The binding of these probes with DNA was investigated using spectral (Electronic, fluorescence, H-1 NMR and circular dichroism) and molecular docking studies. These probes exhibited a strong fluorescence around 440 nm upon excitation around 380 nm. Electronic and competitive fluorescence titration studies, in HEPES [(4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid)] buffer/dimethyl sulfoxide (pH 7.4) medium, suggest that these probes bind strongly to DNA, which is substantiated by H-1 NMR study. The binding constants are calculated to be 5.3 x 10(7) and 6.8 x 10(6) M–(1) for R1 and R2, respectively. From the results of spectral studies, it is proposed that the mechanism of binding of these probes with DNA is through minor groove binding mode, which is further confirmed by circular dichroism and molecular docking studies. Initial cell viability screening using MTT (3-[4,5-methylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay shows that normal Vero cells are viable towards these probes at nano molar concentration, which is the concentration range employed in the present study for DNA staining (IC50 in the order of 0.023 mM). The enhancement in fluorescence intensity of these probes upon binding with DNA enables the staining of DNA in agarose gel in gel electrophoresis experiment. The sensitivity of these probes is comparable with that of ethidium bromide and DNA amounts as low as 4 nano gram are detectable. Communicated by Ramaswamy H. Sarma

A novel ratiometric fluorescent probe based on coumarin derivative for the recognition of Al(III) and its application on test strips

A novel ratiometric probe (L) which was composed of chromone and coumarin moieties has been designed and synthesized for sensing Al3+ in EtOH in view of the internal charge transfer (ICT) mechanism. The free probe L exhibited a strong fluorescence emission at 477 nm, and the fluorescence emission here almost disappeared after adding Al3+ (10 equiv.) while a new peak appeared at 524 nm. This may be due to the enhancement of intramolecular electron transfer efficiency from donor to acceptor. In addition, this probe L could be form a 1:1 complex with Al3+, which could be explained by the ESI-MS spectra, and L had a low detection limit for Al3+ with a binding constant of 1.32 x 10(4) M-1 More importantly, L could be applied to a solid probe for rapid detection of Al3+ with a significant color change.

Dibenzopyrrolo[1,2-a][1,8]naphthyridines: Synthesis and Structural Modification of Fluorescent L-Shaped Heteroarenes

The L-shaped, pi-extended pentacycle dibenzopyrrolo[1,2-a][1,8]naphthyridine and its derivatives were synthesized using two methods: fully intramolecular [2 + 2 + 2] cycloaddition and oxidative aromatization using substituted carbodiimide and modification of an electron-rich indole ring of an L-shaped skeleton via electrophilic reaction and cross-coupling. These L-shaped compounds emitted fluorescence in high quantum yield. The position of substituents affected the fluorescence color through two different mechanisms, x-conjugation and skeletal distortion, which caused the substituted L-shaped compounds to emit fluorescence in a variety of colors and to exhibit solvato-fluorochromism.
