Nafie, Mohamed S.; Elghazawy, Nehal H.; Owf, Salma M.; Arafa, Kholoud; Abdel-Rahman, Mohamed A.; Arafa, Reem K. published an article on January 5 ,2022. The article was titled 《Control of ER-positive breast cancer by ERα expression inhibition, apoptosis induction, cell cycle arrest using semisynthetic isoeugenol derivatives》, and you may find the article in Chemico-Biological Interactions.Category: chlorides-buliding-blocks The information in the text is summarized as follows:

New semi-synthetic effective and safe anticancer agents isoeugenol derivatives were synthesized, characterized, and screened for their cytotoxic activity against MCF-7. Moreover, their selective cytotoxicity was assessed against MCF-10A. Three derivatives, 2, 8 and 10 were significantly more active than the reference drug 5-FU with IC50 values of 6.59, 8.07 and 9.63 and 30.93 μM, resp. Also interestingly, these derivatives demonstrated some degree of selectivity to cancer cells over normal cells. Furthermore, derivative 2 was subjected to other in vitro experiments against MCF-7 where it inhibited colony formation by 87.5% and lowered ERα concentration to 395.7 pg/mL compared to 1129 pg/mL in untreated control cells. In continuation of the investigation, the apoptotic activity of compound 2, was assessed where it significantly enhanced total apoptotic cell death by 9.16-fold (18.70% compared to 1.64% for the untreated MCF-7 control cells) and arrested the cell cycle at the G2/M phase. Furthermore, the mol. mechanism of apoptotic activity was investigated at both the gene (RT-PCR) and protein (western plotting) levels where upregulation of pro-apoptotic and down regulation of anti-apoptotic genes was detected. Addnl., compound 2 treatment enhanced the antioxidant (GSH, CAT, SOD) activities. Finally, in vivo experiments verified the effective anticancer activity of compound 2 through inhibition of tumor proliferation by 47.6% compared to 22.9% for 5-FU and amelioration of the hematol., biochem., and histopathol. examinations near normal. In effect, compound 2 can be viewed as a promising semi-synthetic derivative of isoeugenol with some degree of selectivity for management of breast cancer through apoptotic induction and ERα downregulation.

And the article was published in Science (Washington, DC, United States) in 2021. Safety of 2-Chloroisonicotinic acid The author mentioned the following in the article:

Hydroxylation of aryl carbon-hydrogen bonds with transition metal catalysts has proven challenging when oxygen is used as the oxidant. Here, we report a palladium complex bearing a bidentate pyridine/pyridone ligand that efficiently catalyzes this reaction at ring positions adjacent to carboxylic acids. IR, x-ray, and computational anal. support a possible role of ligand tautomerization from mono-anionic (L,X) to neutral (L,L) coordination in the catalytic cycle of aerobic carbon-hydrogen hydroxylation reaction. The conventional site selectivity dictated by heterocycles is overturned by this catalyst, thus allowing late-stage modification of compounds of pharmaceutical interest at previously inaccessible sites. In addition to this study using 2-Chloroisonicotinic acid, there are many other studies that have used 2-Chloroisonicotinic acid(cas: 6313-54-8Safety of 2-Chloroisonicotinic acid) was used in this study.

And the article was published in Journal of Heterocyclic Chemistry in 2010. Safety of 2-(2-Chloroethoxy)ethyl acetate The author mentioned the following in the article:

Sulfanyl-glycosides have been synthesized by reaction of dimercaptoquinoxaline I (R = H) with aceto-halo sugars in presence of base to give the thioglycosides-derived quinoxalines, e.g. II. Similarly, the acyclic analogs, e.g. I (R = Me), were prepared by coupling of I (R = H) with different acyclo-alkylating agents. The preparation of 3-morpholinyl quinoxalines allowed the synthesis of 3-glycosylsulfanyl-2-morpholinyl quinoxalines as well as the acyclic analogs. Microwave irradiation of the reactants turned out to be preferred over the conventional method for achieving the synthetic goals.

Verhagen, Frank J. M.; Van Assema, Friso B. J.; Boekema, Bouke K. H. L.; Swarts, Henk J.; Wijnberg, Joannes B. P. A.; Field, Jim A. published an article on January 15 ,1998. The article was titled 《Dynamics of organohalogen production by the ecologically important fungus Hypholoma fasciculare》, and you may find the article in FEMS Microbiology Letters.Reference of 3,5-Dichloro-4-methoxybenzoic acid The information in the text is summarized as follows:

The ecol. important white rot basidiomycete Hypholoma fasciculare was previously shown to produce large amounts of adsorbable organic halogens (AOX). The purposes of this study were to identify the time period of AOX production in relation to the primary and secondary metabolic phases of the growth cycle of the fungus, to determine the maximal specific AOX production rates and final AOX yields on the different substrates and to account for the measured AOX in identifiable compounds The AOX production was observed to take place during the transition between the primary and secondary metabolic phases of the growth cycle of the fungus. The maximum AOX production rates ranged from 0.63 to 3.23 mg AOX per g of dry mycelium per day and the final AOX yields ranged from 0.88 and 1.50 percent of dry weight of mycelium on five different substrates including natural woody substrates. The AOX produced by the fungus was stable in all five substrates, even after prolonged incubation periods. However, the composition of the AOX changed drastically. Initially most of the AOX was accounted for by the compound 3,5-dichloro-p-anisyl alc.; however, after prolonged incubation this compound was largely converted into 3,5-dichloro-p-anisic acid in N-rich medium and into unidentified organohalogens in N-limited medium. The experimental process involved the reaction of 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7Reference of 3,5-Dichloro-4-methoxybenzoic acid)

Name: (3-Fluorophenyl)boronic acid. The article was titled 《Combating fluconazole-resistant fungi with novel β-azole-phenylacetone derivatives》. The information in the text is summarized as follows:

A series of β-azole-phenylacetone derivatives I (R1 = H, 2-F, 3-F, etc. ; R2 = 2-CH3, 4-F, 2-Cl, etc.; R3 = 3-Cl, 4-F, 4-CH3, etc.) with novel structures were designed and synthesized to combat the increasing incidence of susceptible fungal infections and drug-resistant fungal infections. The antifungal activity of the synthesized compounds was assessed against five susceptible strains and five fluconazole-resistant strains and most of the compounds exhibited excellent antifungal activities with MIC values in the range of 0.03-1 μg/mL. Compounds I (R1 = 3-F, R2 = R3 = H), I (R1 = R2 = H; R3 = 2-F) and I (R1 = 2-F; R2 = H; R3 = 4-CH3) exhibited moderate antifungal activities against fluconazole-resistant strains 17# and CaR with MIC values in the range of 1-8 μg/mL. Compounds I (R1 = 2-F; R2 = R3 = H), I (R1 = R2 = H; R3 = 2-F) and I (R1 = R3 = 2-F; R2 = H) displayed moderate to good antifungal activity against fluconazole-resistant strains 632, 901 and 904 with MIC values in the range of 0.125-4 μg/mL.

In 2019,Journal of Physical Chemistry B included an article by Gregson, F. K. A.; Robinson, J. F.; Miles, R. E. H.; Royall, C. P.; Reid, J. P.. Safety of Sodium chloride. The article was titled 《Drying Kinetics of Salt Solution Droplets: Water Evaporation Rates and Crystallization》. The information in the text is summarized as follows:

Drying and crystallization of solution droplets is a problem of broad relevance, determining the microstructures of particles formed in spray-drying, the phase of particles delivered by, for example, aerosol formulations for inhalation therapies, and the impact of aerosols on radiative forcing and climate. The ephemeral nature of free droplets, particularly when considering the drying kinetics of droplets with highly volatile constituents, has often precluded the accurate measurement of transient properties such as droplet size and composition, preventing the robust assessment of predictive models of droplet-drying rates, nucleation, and crystallization Here, the authors report novel measurements of the drying kinetics of individual aqueous sodium chloride solution droplets using an electrodynamic balance to isolate and trap single aerosol droplets (radius ≈ 25 μm). The initial solution droplet size and composition are highly reproducible in terms of drying rate and crystallization time when examined over hundreds of identical evaporating droplets. The authors introduce a numerical model that determines the concentration gradient across the radial profile of the droplet as it dries, considering both the surface recession because of evaporation and the diffusion of components within the droplet. Drying-induced crystallization is fully determined for this system, with nucleation and instantaneous crystallization occurring once a critical supersaturation level of 2.04 ± 0.02 is achieved at the surface of the evaporating droplet. This phenomenol. model provides a consistent account of the timescale and surface concentration of free-droplet crystallization on drying for the different drying conditions studied, a necessary step in progress toward achieving control over rates of crystallization and the competitive formation of amorphous particles.
