Liver cancer is one of the most important cancers that easily affects many organs in the body. Valproate is a well-known branched fatty acid and is commonly used as an antiepileptic in liver cancer therapy. Similar to many drugs, this chemical drug can induce fulminant liver failure in patients with liver cancer. So, finding new therapeutic agents with fewer side effects is of great attention. This study explains synthesis and characterization of a new effective nanocatalyst ZnO@SiO2-NH2, which can be a suitable candidate for valproate. The prepared nanocatalyst was characterized by FT-IR, TEM, XRD and FE-SEM and formation of the desired nanoparticles with a medium grain size of 70-90 nm is justified. Then, the synthesized nanocatalyst is checked in the multi-component synthesis of some important model drugs involving substituted 2-aminothiophenes, as effective compounds against human liver cancer. The present methodology showed good generality and wide scope, nearly short span of time, good yield, easy workup and environmental friendly conditions for the preparation of the target compounds. At the final part of this study, the in vitro cytotoxicity potential of the prepared nanoparticle is investigated against a well-known human cancer cell line HepG2 via the MTT assay. The experiments reveal that ZnO@SiO2-NH2 nanoparticles have significant cytotoxicity towards the selected cell line. As a result, although ZnO@SiO2-NH2 can be used to treat liver cancer cells, however, this nanoparticle can be utilized to synthesize 2-aminothiophenes, as effective anti-liver cancer drugs like valproate.

Four new series of aromatic sulfamates were synthesized and investigated for the inhibition of four human (h) isoforms of zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), hCA I, II, IX, and XII. The reported derivatives, obtained by a sulfamoylation reaction of the corresponding phenolic precursors, bear 3,5-diarylpyrazoline moieties as spacers between the benzenesulfamate fragment which binds the zinc ion from the active site, and the tail of the inhibitor. Pyrazolines are biologically privileged scaffolds, endowed with versatile biological activity, such as an anti-proliferative action. The derivatives were tested for the inhibition of the cytosolic, hCA I and II (off target isoforms) and the trans-membrane, tumor-associated hCA IX and XII enzymes (anticancer drug targets). Generally, hCA I was not effectively inhibited, whereas many low nanomolar inhibitors were evidenced against hCA II (KIs in the range of 0.42-90.1 nM), IX (KIs in the range of 0.72-63.6 nM), and XII (KIs in the range of 0.88-85.2 nM). The best substitution fragments at the pyrazoline ring included for CA it a 4-sulfamic group on the 3-aryl and halogens on the 5-aryl or a methoxy group on the 3-aryl and a 4-sulfamate group on the 5-aryl; for CA IX and CA XII they included the sulfamic group on the 3- or 4-position of the 5-aryl and an electronwithdrawing group on the 4-postion of the 3-aryl ring.

A triflatostannylene [(LSn)-Sn-dagger(ii)][OTf] (2) is reported here as an efficient catalyst with low-valent main-group element for the hydroboration of aldehydes and ketones (L-dagger = aminotroponate). Using 0.025-0.25 mol% of compound 2, hydroboration of various aldehydes and ketones is accomplished in 0.13-1.25 h at room temperature; the aliphatic aldehydes show an impressive TOF of around 30000 h(-1). DFT calculations are performed to explore the mechanistic aspects of this reaction suggesting that the reaction proceeds via a stepwise pathway with hydridostannylene [(LSn)-Sn-dagger(ii)H] (2a) as the active catalyst and the H atom transfer from the Sn-H bond to the carbonyl carbon being the rate determining step.

Bimetallic nanocatalysts, with efficient and controllable catalytic performance, have a promising application in chemical production. In this study, surface Pt-rich bimetallic AuPt nanoparticles with different Pt/Au ratios were prepared and tested in selective hydrogenation reactions of substituted nitroaromatics. Au nanoparticles were first prepared with n-butyllithium as a rapid reducer, which were further used as seeds in the slow growth process of Pt atoms. Because of the employed sequential reduction method and the following atom diffusion, surface Pt-rich bimetallic AuPt nanoparticles were obtained. Compared with the uniform AuPt alloy nanocatalysts synthesized by the co-reduction method with n-butyllithium as the reducer and monometallic Pt nanocatalysts, the obtained surface Pt-rich AuPt bimetallic nanocatalysts presented an enhanced catalytic selectivity or activity. The performance enhancement is assigned to the optimized Au/Pt interaction in the surface Pt-rich bimetallic nanostructures. This work demonstrates that the optimization of the stoichiometry and construction of bimetallic materials is a feasible method to synthesize controllable and efficient nanocatalysts.

Thirty-eight chalcone derivatives bearing a chromen or benzo[f]chromen moiety were synthesized and evaluated for their anti-inflammatory and analgesic activities. Using an ear edema model, anti-inflammatory activities were observed for compounds 3a-3s (ear inflammation: 1.75-3.71 mg) and 4a-4s (ear inflammation: 1.71-4.94 mg). All compounds also displayed analgesic effects with inhibition values of 66.7-100% (3a-3s) and 96.2-100% (4a-4s). The 12 compounds that displayed excellent anti-inflammatory and analgesic effects were tested for their inhibitory activity against ovine COX-1 and COX-2. Six compounds bearing a chromen moiety were weak inhibitors of the COX-1 isozyme but showed moderate COX-2 isozyme inhibitory effects (IC(50)s from 0.37 mu M to 0.83 mu M) and COX-2 selectivity indexes (SI: 22.49-9.34). Those bearing a benzo[f]chromen moiety were more selective toward COX-2 than those bearing a chromen moiety with IC(50)s from 0.25 mu M to 0.43 mu M and COX-2 selectivity indexes from SI: 31.08 to 20.67.

I found the field of Chemistry very interesting. Saw the article Acid-Catalyzed Condensation of o-Phenylenediammines and o-Aminophenols with alpha-Oxodithioesters: A Divergent and Regio-selective Synthesis of 2-Methylthio-3-aryl/Heteroarylquinoxalines and 2-Acylbenzoxazoles published in 2019.0.

o-Phenylenediammines ando-aminophenols were reacted with alpha-oxodithioesters in a highly regioselective fashion to give 2-methylthio-3-aryl/heteroarylquinoxalines and 2-acylbenzoxazoles in 55-94% and 45-86%, respectively, in the presence ofp-toluene sulfonic acid catalyst. Control experiments involving reaction of aniline with a alpha-oxodithioester indicated that the thiocarbonyl group is more reactive than the carbonyl group. Based on this, probable mechanisms for the formation of quinoxalines and benzoxazoles are given. Biological targets of the quinoxalines and benzoxazoles were identified by bioinformatics. It was found that quinoxalines have good binding affinity with human dual-specificity tyrosine-phosphorylation-regulated kinase 1A and benzoxazoles with human carboxylesterase.
