High-throughput screening highlighted 9-oxo-9H-indeno[1,2-b]pyrazine-2,3- dicarbonitrile (1) as an active inhibitor of ubiquitin-specific proteases (USPs), a family of hydrolytic enzymes involved in the removal of ubiquitin from protein substrates. The chemical behavior of compound 1 was examined. Moreover, the synthesis and in vitro evaluation of new compounds, analogues of 1, led to the identification of potent and selective inhibitors of the deubiquitinating enzyme USP8.
Kinetic resolution of racemic benzofused alcohols catalysed by HMFO variants in presence of natural deep eutectic solvents
Fraaije, Marco,Lon?ar, Nikola,de Gonzalo, Gonzalo
, (2022/03/01)
5-Hydroxymethylfurfural oxidase (HMFO) has demonstrated to be a useful biocatalyst for the selective oxidation of alcohols employing oxygen as mild oxidant with no requirement of expensive organic cofactors. This wild-type HMFO biocatalyst and an engineered thermostable variant have been tested in the kinetic resolution of different benzofused alcohols. The use of natural deep eutectic solvents was also explored in HMFO-catalysed oxidation of alcohols. The oxidation of racemic 1-indanol showed a higher conversion and selectivity in presence of 60% v/v of different NADES, especially for those containing carbohydrates. By choosing properly the biocatalyst and the NADES, good enantioselectivity values can be obtained, demonstrating the advantages of employing these neoteric solvents in biocatalysed processes.

Background: The synthesis of 2-[3/4-((6-substituted-1-oxo-2,3-dihydro-1H-inden-2-ylidene)methyl)phenoxy]-N-(heteroaryl)acetamide derivatives and the investigation of their anticancer activity were studied. Methods: 2-(3/4-Hydroxybenzylidene)-6-substituted-2,3-dihydro-1H-inden-1-ones were reacted with suitable 2-chloroacetamides to give 2-[3/4-((6-substituted-1-oxo-2,3-dihydro-1H-inden-2-ylidene) methyl)phenoxy]-N-(heteroaryl)acetamide derivatives. Results: The structure elucidation of the newly synthesised 16 compounds was performed by IR, 1H-NMR, mass spectroscopic data and elemental analyses. The anticancer screening was carried out in National Cancer Institute (NCI), USA. Conclusion: Compound 3e (2-(3-((6-chloro-1-oxo-2,3-dihydro-1H-inden-2-ylidene)methyl)phenoxy)-N-(thiazol-2-yl)acetamide), exhibited highest growth inhibition against the leukaemia (61.47%), non-small cell lung cancer (79.31%) and breast cancer (62.82%) cell lines.
Benzo cyclic ketone compound preparation method
-
Paragraph 0023; 0024, (2018/03/26)
The invention discloses a benzo cyclic ketone compound preparation method, which specifically comprises: adding a phenyl acyl chloride compound into a solvent hexafluoroisopropanol in a dropwise manner, and under the catalytic effect of a catalyst Lewis acid (aluminum trichloride or iron trichloride), carrying out a reaction at a temperature of 0-59 DEG C until the acyl chloride is completely converted so as to obtain the benzo cyclic ketone compound. According to the present invention, the benzo cyclic ketone compound is prepared through the cyclization reaction by using the hexafluoroisopropanol as the solvent, such that the use of a large amount of Lewis acid or strong protic acid is avoided so as to substantially reduce the generation of three wastes and provide the less corrosivenessto the equipment; and the method of the present invention is environmentally friendly and safe, and has good economical benefits.

supporting information, p. 13052 - 13057 (2015/09/07)
We have developed a method for recyclable hypervalent-iodine-mediated direct dehydrogenative α,β′- bifunctionalization of β-ketoesters and β-diketones under metal-free conditions, which affords a straightforward way to synthesize benzo-fused 2,3-dihydrofurans. This efficient, mild method, which has a wide substrate scope and good functional-group tolerance, was used for the multistep synthesis of the protected aglycone of a naturally occurring phenolic glycoside. A mechanism involving Michael addition to an enone intermediate and subsequent oxidative cyclization is proposed.

, p. 5599 - 5610 (2014/06/10)
1-Indanones have been successfully prepared by means of three different non-conventional techniques, namely microwaves, high-intensity ultrasound and a Q-tube reactor. A library of differently substituted 1-indanones has been prepared via one-pot intramolecular Friedel-Crafts acylation and their efficiency and "greenness" have been compared.

Cao, Weidi,Liu, Xiaohua,Peng, Ruixue,He, Peng,Lin, Lili,Feng, Xiaoming
supporting information, p. 3470 - 3472 (2013/05/23)
A cooperative bimetallic catalyst system was applied in the catalytic asymmetric cross-dehydrogenative coupling of β-ketoesters and xanthene. Various optically active xanthene derivatives bearing a quaternary stereogenic carbon center were obtained in moderate to good yields (up to 90%) with excellent enantioselectivities (up to 99% ee). Meanwhile, a transition-state model was proposed to explain the origin of the asymmetric induction.
