Crystal structures, Hirshfeld surface analysis and PIXEL energy calculations of three trifluoromethylquinoline derivatives: further analyses of fluorine close contacts in trifluoromethylated derivatives

As many studies have revealed, the introduction of a CF3 group into an organic compound can result in significant enhancement of biological activity. Factors which lead to this enhancement are thus of great interest. To investigate further this area, we have looked at the ability of fluorine to form close contacts with various atoms in organic compounds, e.g. F center dot center dot center dot F, F center dot center dot center dot O/O center dot center dot center dot F, F center dot center dot center dot C/C center dot center dot center dot F, H center dot center dot center dot F/F center dot center dot center dot H and F center dot center dot center dot N/N center dot center dot center dot F, as indicated from crystal structure determinations and Hirshfeld analysis studies on trifluoromethylated compounds. Herein we first report the crystal structures, Hirshfeld surface analyses (HSA), and PIXEL energy calculations of three trifluoromethylated quinoline derivatives, namely 2-(trifluoromethyl) quinolin-4-ol, 1, 4-ethoxy-2-(trifluoromethyl)quinoline, 2, and N-1-(2,8-bis(trifluoromethyl)quinolin-4-yl)ethane-1,2-diamine, 3. Of particular interest is the determination of the various fluorine. atom close contacts. The total percentages of fluorine. -atom close contacts in compounds 1-3 were determined to be high at 47, 41.2 and 60.7%, respectively. As relatively few HSA studies on trifluoromethylated compounds have reported the percentages of individual atom atom close contacts, we have also determined the percentages of atom center dot center dot center dot atom close contacts for 20 more trifluoromethylated compounds: the range of total fluorine center dot center dot center dot atom close contacts for these compounds was 20-60%. While these data are based on connections between similar molecules in a crystalline state, they also clearly suggest that a compound containing CF3 group(s) has the potential to make extensive intermolecular connections/close contacts with organic material. Thus a possible factor for the enhanced biological activity of a compound bearing CF3 group(s) could be the propensity of the CF3 group to form many close contacts, thereby aiding binding or interaction with a biological target.

Correlation of in Situ Oxazolidine Formation with Highly Synergistic Cytotoxicity and DNA Cross-Linking in Cancer Cells from Combinations of Doxorubicin and Formaldehyde

Anthracyclines are a class of antitumor compounds that are successful and widely used but suffer from cardiotoxicity and acquired tumor resistance. Formaldehyde interacts with anthracyclines to enhance antitumor efficacy, bypass resistance mechanisms, improve the therapeutic profile, and change the mechanism of action from a topoisomerase II poison to a DNA cross-linker. Contrary to current dogma, we show that both efficient DNA cross-linking and potent synergy in combination with formaldehyde correlate with the anthracycline’s ability to form cyclic formaldehyde conjugates as oxazolidine moieties and that the cyclic conjugates are better cross-linking agents and cytotoxins than acyclic conjugates. We also provide evidence that suggests that the oxazolidine forms in situ, since cotreatment with doxorubicin and formaldehyde is highly cytotoxic to dox-resistant tumor cell lines, and that this benefit is absent in combinations of formaldehyde and, epirubicin, which cannot form stable oxazolidines. These results have potential clinical implications in the active field of anthracydine prodrug design and development.

Effect of Tanning Agents on Collagen Structure and Response to Strain in Leather

A variety of tanning agents are used to produce leather of different mechanical performances and properties. How different tanning agents affect the structure of leather, and consequently the mechanism underlying the performance of the differently tanned leathers, is not well understood. We used small-angle X-ray scattering to investigate the structure of ovine leather tanned with chromium, zirconium, mimosa, oxazolidine or tetrakis hydroxymethyl phosphonium sulfate (THPS), or selected pairs of these agents. Leather tanned using THPS and THPS in combination with mimosa retained the most oriented collagen fibril structure. Treatment with chromium, zirconium or zirconium and mimosa resulted in the least oriented fibril structures. The effect of oxazolidine with mimosa was intermediate between these. A high natural collagen fibril orientation in a skin is normally associated with high strength while a high degree of crosslinking normally results in a lower fibril orientation. We suggest that the extent of crosslinking in the samples is reflected in their fibril orientation, with more crosslinking producing stronger leathers. This interpretation is supported by the differences in shrinkage temperatures: those leathers for which orientation index (a measure of collagen fibril alignment) changed most had a lower shrinkage temperature (which is normally interpreted as more tanning). This provides a greater understanding of the mechanism of action of tanning agents in the development of the properties of leather.

1D Azido bridged Cu(II) coordination polymer with 1,3-oxazolidine ligand as an effective catalyst for green click synthesis of 1,2,3-triazoles

A new 1D azido bridged Cu(II) coordination polymer with 1,3-oxazolidine based ligand, [Cu(H3L)(mu(1,3)-N-3)(N-3)](n) (1), was synthesized and characterized by elemental analysis and spectroscopic methods. The structure of 1 was also determined by single crystal X-ray analysis which indicated the 1D polymeric chain is generated by end-to-end (EE) azide bridge. The obtained compound was employed as catalyst in green click synthesis of beta-hydroxy-1,2,3-triazoles from one-pot three-component cycloaddition reaction of epoxide-azide-alkyne. The catalytic reactions were carried out in water as a safe, cheap and green solvent. The catalytic studies indicated that the obtained 1D azido bridged Cu(II) coordination polymer is an active catalyst for preparing beta-hydroxy-1,2,3-triazoles. The effect of temperature on the selectivity of the catalytic system was studied and the results indicated this catalytic system has high selectivity at low temperatures. The structure the product obtained from the reaction of 2,3-epoxypropylphenylether, azide and 1-ethynyl-1-cyclohexanol (T4) was determined by single crystal X-ray analysis. The results indicate Cu(II) coordination polymers can be a new class of catalytic systems for green click synthesis of 1,2,3-triazoles.

CHIRAL OXAZOLIDINE CATALYST FOR ASYMMETRIC SYNTHESIS

A design of a chiral ligand and its metal-coordinated catalyst is very important for achievement of a highly optical purity and a chemical yield in an asymmetric reaction. Recently, we developed the chiral oxazolidine ligands having N,O-acetal structure, such as phosphinooxazolidine (POZ), phosphinooxazinane (POZI) and oxazolidine (OZ). POZ and POZI afforded products in an excellent enantioselectivities in Pd-catalyzed asymmetric allylic alkylation and tandem allylation. Furthermore, cationic Pd-POZ catalysts showed high levels of catalytic activity in the asymmetric Die Is-Alder (DA) reactions of some dienes with oxazolidinone or pyrrazolidinone typed dienophiles. Cationic Pd-POZ catalyst showed an excellent catalytic activity in the DA reaction in ionic liquid (IL). The catalyst could be reused eight times without significant decrease of yield and enantioselectivity in the use of an ionic liquid as a solvent. OZ ligand also worked as organocatalyst in the DA reaction of 1,2-dihydropyridines with acroleins to afford the useful intermediate of Tamiflu. The review summarizes these our studies.

Dithienylethene-Based Gated Ambichromic Dyads

A set of dithienylethene (DTE)-based ambichromic dyads containing an acido-, photo-, and electrosensitive indolino[2,1-b] oxazolidine (BOX) unit displays gated photochromism. Ring opening of BOX prevents photoinduced electrocylization between open and closed forms of DTE. The photochromic performances are regenerated by two different pathways. NMR and electrochemical studies evidence interactions between indolenium and phenyl-thienyl sidearms.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 99395-88-7 is helpful to your research. Formula: C9H9NO2.

Spiro-fused carbohydrate oxazoline ligands: Synthesis and application as enantio-discrimination agents in asymmetric allylic alkylation

In the present work, we describe a convenient synthesis of spiro-fused D-fructo-and D-psico-configurated oxazoline ligands and their application in asymmetric catalysis. The ligands were synthesized from readily available 3,4,5-tri-O-benzyl-1,2-O-isopropylidene-beta-D-fructopyranose and 3,4,5-tri-O-benzyl-1,2-O-isopropylidene-beta-D-psicopyranose, respectively. The latter compounds were partially deprotected under acidic conditions followed by condensation with thiocyanic acid to give an anomeric mixture of the corresponding 1,3-oxazolidine-2-thiones. The anomeric 1,3-oxazolidine-2-thiones were separated after successive benzylation, fully characterized and subjected to palladium catalyzed Suzuki-Miyaura coupling with 2-pyridineboronic acid N-phenyldiethanolamine ester to give the corresponding 2-pyridyl spiro-oxazoline (PyOx) ligands. The spiro-oxazoline ligands showed high asymmetric induction (up to 93% ee) when applied as chiral ligands in palladium-catalyzed allylic alkylation of 1,3-diphenylallyl acetate with dimethyl malonate. The D-fructo-PyOx ligand provided mainly the (R)-enantiomer while the D-psico-configurated ligand gave the (S)-enantiomer with a lower enantiomeric excess.

Oxazolidine Derivatives as Corrosion Inhibitors for API X60 Steel in 1 M HCl Solution: Experimental and Theoretical Studies

Some synthesized oxazolidine derivatives (1-oxa-4-azaspiro [4,4]nonane, 1-oxa-4-azaspiro [4,5]decane, 6-methyl-1-oxa-4-azaspiro [4,5]decane and 1-oxa-4-azaspiro [4,7]dodecane) have been tested as promising inhibitors for API 5L X60 steel corrosion in a 1 M HCl solution using weight loss and electrochemical techniques complemented with computational studies. Characterization of the synthesized compounds was achieved using H-1 and C-13 NMR spectroscopic analysis. The oxazolidine derivatives could efficiently lower the corrosion rate of the steel sample during 24 h of immersion in an acidic medium. The oxazolidine derivatives have minimal effect on the corrosion potential of steel in the acid solution. Their adsorption onto the steel surface effectively improved the charge transfer resistance, and the oxazolidine compounds acted as mixed-type inhibitors. A cyclooctyl substitution at the C-11 position produced the highest inhibitor efficiency, and attachment of a methyl group could enhance the inhibition efficiency of the cyclohexyl substituent at the C-11 position. Density functional theory calculations were conducted to gain insight into the structural and electronic properties of the four corrosion inhibitors and their inhibitory effects.

Exploring the microbiota and metabolites of traditional rice beer varieties of Assam and their functionalities

Rice beer is traditionally prepared and consumed by various ethnic populations in the Southeast Asian countries. To understand the probable effects of rice beer on human health, present research was aimed to study biochemical parameters, microbial diversity and metabolites of major rice beer varieties of Assam, namely Apong (Poro and Nogin), Xaaj and Joubishi. Alcoholic content of rice beer varieties varied from 9.41 to 19.33% (v/v). Free radical scavenging activity against DPPH center dot and ABTS(+) were 1.94-4.14 and 1.69-3.91mg of ascorbic acid/ml of rice beer, respectively. In relation to antioxidant activities, phenolic content varied from 2.07 to 5.40mggallic acid/ml of rice beer. Next-generation sequencing of 16S rDNA showed that 18 genera of bacteria were present irrespective of rice beer varieties in which lactic acid bacteria were the dominant group (90% abundance). Functional predictions based on the bacterial profiles indicated pathways, such as metabolisms of carbohydrate, amino acid, vitamins and co-factors, and xenobiotic biodegradation, to be active in the rice beer varieties. Out of 18 core bacterial genera, 7 had correlations with the predicted functions. Gas chromatography and mass spectroscopy-based metabolite analysis revealed that the metabolite profiles of the rice beer varieties consisted of 18 saccharides, 18 organic acids, 11 sugar alcohols, 8 amino acids, 1 vitamin and nutraceutical compounds thiocoumarine, carotene, oxazolidine-2-one and acetyl tyrosine. Due to the presence of potent prebiotics, probiotics and nutraceuticals, rice beer may have health benefits which need to be studied further.
