Saw the article Lead Optimization of Benzoxazolone Carboxamides as Orally Bioavailable and CNS Penetrant Acid Ceramidase Inhibitors published in 2020.0, Reprint Addresses Skerlj, R (corresponding author), Lysosomal Therapeut Inc, Cambridge, MA 02139 USA.; Scarpelli, R (corresponding author), Fdn Ist Italiano Tecnol, Drug Discovery & Dev D3 Validat, I-16163 Genoa, Italy.. The CAS is 59-48-3. Through research, I have a further understanding and discovery of Indolin-2-one.

Sphingolipids (SphLs) are a diverse class of molecules that are regulated by a complex network of enzymatic pathways. A disturbance in these pathways leads to lipid accumulation and initiation of several SphL-related disorders. Acid ceramidase is one of the key enzymes that regulate the metabolism of ceramides and glycosphingolipids, which are important members of the SphL family. Herein, we describe the lead optimization studies of benzoxazolone carboxamides resulting in piperidine 22m, where we demonstrated target engagement in two animal models of neuropathic lysosomal storage diseases (LSDs), Gaucher’s and Krabbe’s diseases. After daily intraperitoneal administration at 90 mg kg(-1), 22m significantly reduced the brain levels of the toxic lipids glucosylsphingosine (GluSph) in 4L;C* mice and galactosylsphingosine (GalSph) in Twitcher mice. We believe that 22m is a lead molecule that can be further developed for the correction of severe neurological LSDs where GluSph or GalSph play a significant role in disease pathogenesis.

Herein, we report a highly chemoselective and efficient heterogeneous MnO2@Fe3O4 MNP catalyst for the oxidation of benzylic sp(3) C-H group of ethers using TBHP as a green oxidant to afford ester derivatives in high yield under batch/continuous flow module. This catalyst was also effective for the benzylic sp(3) C-H group of methylene derivatives to furnish the ketone in high yield which can be easily integrated into continuous flow condition for scale up. The catalyst is fully characterized by spectroscopic techniques and it was found that 0.424 % MnO2@Fe3O4 catalyzes the reaction; the magnetic nanoparticles of this catalyst could be easily recovered from the reaction mixture. The recovered catalyst was recycled for twelve cycles without any loss of the catalytic activity. The advantages of MnO2@Fe3O4 MNP are its catalytic activity, easy preparation, recovery, and recyclability, gram scale synthesis with a TOF of up to 14.93 h(-1) and low metal leaching during the reaction.

14192-26-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 14192-26-8 as follows.

To the suspension of methyl 2-oxoindoline-6-carboxylate (50 gm, 0.261 mol) in IPA (350 ml) was added slowly SMO-powder (33.8 gm, 0.626 mol) and stirred for about 15 min. Benzyl chloride (44 g, 0.313 mol) was added after completion of the reaction at a reaction temperature of -5 to -10C for about 5hrs. The reaction mixture was quenched into ice-water (700 ml) and acidified with Cone. HC1 (2.0-2.5 ml). Filtered the reaction mixture, washed with water (2X100 ml) and dried the precipitate to obtain crude product which can be recrystallized from acetonitrile (28 ml) to obtain methyl-3-(hydroxy(phenyl)methylene)-2- oxoindoline-6-carboxylate pure crystalline solid (32 gm) (61%) (HPLC purity >97%). The filtrate was evaporated in vacuum to give unreacted methyl 2-oxoindoline-6-carboxylate.

The synthetic route is as follows., Formula: C9H8F3NO

Under N2 flow at 5C, propylphosphonic anhydride (2.56 ml_, 4.26 mmol) was added dropwise to a mixture of 6-(thfluoromethoxy)indoline [CAS 953906-76-8] (577 mg, 2.84 mmol), 2-(4-chlorophenyl)-2-((3-(2-hydroxyethoxy)-5-methoxy- phenyl)amino)acetic acid 3f (1 .3 g, 3.70 mmol) and diisopropylethylamine (1 .03 ml_, 6.25 mmol) in 2-Me-THF (30 ml_). The mixture was stirred at room temperature for 4 h. Water was added and the mixture was extracted with EtOAc. The organic layer was washed with a 10% solution of K2CO3 in water and then with water, dried over MgSO4, filtered, and the solvent was evaporated under reduced pressure. Purification was carried out by flash chromatography on silica gel, (15-40 muiotatauiota, 40 g, Ch C /MeOH 99/1 ). The pure fractions were combined and evaporated to dryness, to give 2-(4-chlorophenyl)-2-((3-(2-hydroxyethoxy)-5- methoxyphenyl)amino)-1 -(6-(trifluoromethoxy)indolin-1 -yl)ethanone (Compound 3, 800 mg) as a racemic mixture. This fraction was combined with another batch (total amount: 1 .4 g) and crystallized from diisopropyl ether to give 1 .03 g of Compound 3. The enantiomers were separated via Preparative Chiral SFC (Stationary phase: Chiralpak IA 5 muetaeta 250 x 20 mm, Mobile phase: 55% CO2, 45% EtOH (+ 0.3% iPrNh )). The first eluted enantiomer was further purified via reverse phase chromatography (stationary phase: X-bridge-C-18 10 m 30 x 150 mm, mobile phase: 0.2% NH4HCO3/CH3CN gradient 60/40 to 0/100) to give Enantiomer 3A (312 mg).
