Some novel benzoquinoline based heterocyclic monoazo dyes were derived by the diazotization of 1H-benzo[g]pyrazolo[3,4-b]quinoline-3-ylamine with various Ph pyrazolone as coupling components. All the heterocyclic monoazo dyes were characterized by elemental analyses and various spectral data (FT-IR, UV-Vis, ¹H NMR and ¹³C NMR), and their 3D model structures were predicted through B3LYP/6-31G(d,p) method. The dyeing performance on polyester fibers inferred that all the dyes gave moderate to excellent fastness properties on fiber. In addition, colorimetric studies of synthesized dyes were discussed.

Prajapati, Ronak V. published the artcileElemental sulfur and aryl iodides in copper(I)iodide catalyzed sulfenylation of 1-aryl-3-alkyl-1H-pyrazol-5(4H)-ones, Safety of 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is Results in Chemistry (2021), 100226, database is CAplus.

The construction of C-S bond is considered as an important protocol in organic transformations. An innovative strategy for CuI-catalyzed sulfenylation of 1-aryl-3-alkyl-1H-pyrazol-5(4H)-ones have been developed using elemental sulfur as the sulfur source. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 4-sulfenyl pyrazolones with moderate to excellent yields from simple and readily available starting materials. This method might be potentially applicable to large scale production, and it enriches current sulfenylation methods.

Taavitsainen, Paivi published the artcileMetabolism and mass balance of the novel nonsteroidal androgen receptor inhibitor darolutamide in humans, Computed Properties of 1297537-37-1, the publication is Drug Metabolism & Disposition (2021), 49(6), 420-433, database is CAplus and MEDLINE.

The biotransformation and excretion of darolutamide were investigated in a phase I study. Six healthy male volunteers received a single dose of 300 mg ¹⁴C-darolutamide as an oral solution in the fasted state. Plasma, urine, and feces samples were analyzed for mass balance evaluation by liquid scintillation counting (LSC). Metabolite profiling and identification were determined using liquid chromatog. mass-spectrometry with off-line radioactivity detection using LSC. Complete mass balance was achieved, with mean radioactivity recovery of 95.9% within 168 h (63.4% in urine, 32.4% in feces). The administered 1:1 ratio of (S,R)- and (S,S)-darolutamide changed to approx. 1:5, resp., in plasma. Darolutamide and the oxidation product, keto-darolutamide, were the only components quantifiable by LSC in plasma, accounting for 87.4% of total radioactivity, with a 2.1-fold higher plasma exposure for keto-darolutamide. Aside from darolutamide, the most prominent metabolites in urine were O-glucoronide (M-7a/b) and N-glucuronide (M-15a/b), as well as pyrazole sulfates (M-29, M-24) and glucuronides (M-21, M-22) resulting from oxidative cleavage of the parent. The darolutamide diastereomers were mainly detected in feces. In vitro assays showed that darolutamide metabolism involves a complex interplay between oxidation and reduction, as well as glucuronidation. Interconversion of the diastereomers involves oxidation to keto-darolutamide, primarily mediated by CYP3A4, followed by reduction predominantly catalyzed by cytosolic reductase(s), with aldo-keto reductase 1C3 playing the major role. The latter reaction showed stereoselectivity with preferential formation of (S,S)-darolutamide.

Et ester of I reacted in dry Et₂O with HCl to give a salt which, boiled with H₂O, yielded 1-phenyl-3-methyl-4-chloro-5-pyrazolone (VI), m. 153°. Me ester of I yielded the same product. Heating VI with PhNHNH₂ yielded III.
