Synthesis and properties of O-glycosyl calix[4]arenes (calixsugars) was written by Dondoni, Alessandro;Marra, Alberto;Scherrmann, Marie-Christine;Casnati, Alessandro;Sansone, Francesco;Ungaro, Rocco. And the article was included in Chemistry – A European Journal in 1997.Recommanded Product: 14131-84-1 This article mentions the following:

Model O-glycosylation reactions at either rim of calix[4]arenes are described with the aim of providing access to a new family of carbohydrate-containing calixarene derivatives named calixsugars. One or two sugar moieties (D-mannofuranose and D-glucopyranose) were introduced at the lower rim of the parent calix[4]arene by glycosylation of the phenolic hydroxyl groups by means of a Mitsunobu reaction. Tetrapropoxy calix[4]-arenes bearing two or four hydroxymethyl groups at the upper rim were coupled with perbenzoylated thioethyl D-galactoside and D-lactoside in the presence of the thiophilic promoter copper(II) triflate. In this way β-linked bis- and tetrakis-O-galactosyl calix[4]arenes were obtained in good yield, the latter showing some solubility in water. For the O-lactosyl derivatives only the bis-substituted compound could be obtained because of the competing formation of an intramol. ether linkage between 1,3-hydroxymethyl groups. Preliminary binding studies showed some affinity of the galactose-containing calixsugars toward charged carbohydrates and dihydrogen phosphate anion. In the experiment, the researchers used many compounds, for example, (3aS,4S,6R,6aS)-6-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-ol (cas: 14131-84-1Recommanded Product: 14131-84-1).

Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Recommanded Product: 14131-84-1

Application of growth promoting hormones alters the composition and antioxidant potential of dill essential oil under salt stress was written by Ghassemi-Golezani, Kazem;Nikpour-Rashidabad, Neda;Samea-Andabjadid, Samira.

The performance of dill plant may be affected by adverse environments such as salinity. Thus, this research was designed to evaluate changes in chem. composition and antioxidant activity of seed essential oil of dill (Anethum graveolens L.) in response to salinity (0, 5, 10 and 15 dS/m) and 1 mM of each hormonal treatments (gibberellic acid, salicylic acid, and cytokinin). Salicylic acid (SA) reduced Na+ content of roots and leaves by 15.4%, 30.9% and 12.4%, 24.3%, but enhanced K+ content by 29.8%, 51.6% and 76.6%, 73.4% under moderate and severe salinities, resp. Essential oil yield was enhanced with progressing seed filling, despite decreasing essential oil percentage. Percentage of essential oil was increased under low and moderate salinities. Hormonal treatments, particularly SA enhanced seed mass and essential oil percentage, leading to enhanced essential oil yield. The amounts of most constituents were enhanced under moderate salinity. Foliar spray of SA and CK (cytokinin) increased almost all essential oil components, except dill ether and dill apiole, while the GA3 (gibberellic acid) treatment reduced most of the constituents. The α-fenchol was only induced by salt stress. The β-pinene, 1-terpineol, cryptone, oxypeucedanin hydrate, α-thujene and P-α-dimethylstyrene were also specifically synthesized in SA treated plants under salinity. The highest TPC (total phenolic content) and antioxidant activity were recorded for essential oil of SA treated plants at mass maturity under moderate salinity. In general, the SA spray was the most effective treatment for improving essential oil quantity and quality of dill plants.

Investigation of the inhibition of leukotriene A₄ hydrolase was written by Ollmann, Ian R.;Hogg, J. Heather;Munoz, Benito;Haeggstroem, Jesper Z.;Samuelsson, Bengt;Wong, Chi-Huey. And the article was included in Bioorganic & Medicinal Chemistry in 1995.Synthetic Route of C6H11BrO2 This article mentions the following:

In an effort to better understand the favorable binding interactions between the reversible picomolar inhibitor 3-(4-benzyloxyphenyl)-2-(R)-amino-1-propanethiol (1) and leukotriene A₄ (LTA₄) hydrolase (EC 3.3.2.6), we prepared a number of derivatives of 1–L and other related structures, and assayed their inhibition of LTA₄ hydrolase-catalyzed hydrolysis of L-alanine-p-nitroanilide. The inhibition data was analyzed using a weighted non-linear least-squares curve fitting computer program developed for this purpose to fit data derived under the non-Michaelis-Menten condition of [T]_t < [E]_t. The free thiol is necessary for sub-micromolar binding and the enzyme prefers the R enantiomer over the S enantiomer, in contrast to the stereoselectivity displayed towards bestatin, an inhibitor of somewhat similar structure. Substitution of acid moieties around the periphery of the benzyloxyphenyl portion of 1–L leads to substantially decreased binding, suggesting that this group resides within a large hydrophobic pocket when bound to the enzyme. Possible LTA₄ binding modes in the active site of LTA₄ hydrolase, including a possible direct role for the carboxylic acid of LTA₄ in the enzyme-catalyzed hydrolysis of leukotriene A₄, are discussed. In the experiment, the researchers used many compounds, for example, 2-(3-Bromopropyl)-1,3-dioxolane (cas: 62563-07-9Synthetic Route of C6H11BrO2).
