A new responsive material composed of an amphiphilic light-switchable dithienyl ethene unit functionalized with a hydrophobic cholesterol unit and a hydrophilic poly(ethylene glycol)-modified pyridinium group has been designed. This unique single-mol. system shows responsive light-switchable self-assembly in both water and organic solvents. Light-triggered reversible vesicle formation in aqueous solutions is reported. The mol. shows a different behavior in apolar aromatic solvents, in which light-controlled formation of organogel fibers is observed The light-triggered aggregation behavior of this mol. demonstrates that control of a supramol. structure with light can be achieved in both aqueous and organic media and that this ability can be present in a single mol. This opens the way toward the effective development of new strategies in soft nanotechnol. for applications in controlled chem. release systems.

Harvey, Emma C. published the artcileIncorporating cobalt carbonyl moieties onto ethynylthiophene-based dithienylcyclopentene switches. 1. Photochemistry, Formula: C15H14Cl2S2, the publication is Organometallics (2014), 33(2), 447-456, database is CAplus.

Dithienylcyclopentenes I [X = H, F; Y = bond: 1o, M = void; 3o, M = Co₂(CO)₆; 5o, M = Co₂(CO)₄(dppm); Y = 1,4-C₆H₄: 2, M = void; 4, M = Co₂(CO)₆; 6, M = Co₂(CO)₄(dppm)] undergo photochem. conrotatory cyclization, giving the corresponding complexes II [1-C_s – 6-C_s] thus exhibiting photochromic switching properties. The synthesis and characterization of a series of dithienyl perhydro- and perfluorocyclopentene photochromic mol. switches 1o–6o appended with cobalt carbonyl binding 3-ethynylthiophene and phenyl-3-ethynylthiophene substituents are reported. Their photochromic properties, fatigue resistance, and thermal stability were examined to establish the effect of substituents on their performance as mol. photoswitches. The photochem. properties of the dithienylethene core were retained to the greatest extent by the inclusion of Ph units and a hexafluorocyclopentene ring. The alkyne units of the switches were used to coordinate cobalt carbonyl moieties: i.e., Co₂(CO)₆ and Co₂(CO)₄(dppm). The cobalt carbonyl moieties were found to reduce the efficiency of cyclization and cycloreversion of the dithienylethene unit. D. functional theory was used to identify the excited states responsible for cyclization.

Abd El-Karim, Somaia S. published the artcileRational design and synthesis of new tetralin-sulfonamide derivatives as potent anti-diabetics and DPP-4 inhibitors: 2D & 3D QSAR, in vivo radiolabeling and biodistribution studies, Recommanded Product: 5,6,7,8-Tetrahydronaphthalene-2-sulfonyl chloride, the publication is Bioorganic Chemistry (2018), 481-493, database is CAplus and MEDLINE.

Type 2 diabetes (T2D) is a severe disease and it is one of the most raising problems worldwide. This study deals with design, synthesis and in vivo determination of a new set of tetralin-sulfonamide derivatives as anti-diabetic and dipeptidyl peptidase-IV (DPP-4) inhibiting agents. Most of the new compounds exhibited significant hypoglycemic effect alongside with DPP-4 suppression potency considering sitagliptin as a reference drug. The most promising compounds 4, 15 showed 2.80 nM DPP-4 IC₅₀ with 20-40 folds selectivity over DPP-8 and DPP-9. 2D and 3D QSAR models were performed using auto QSAR of Schrodinger, QuaSAR of MOE and 3D Field-based QSAR of Schrodinger, resp. The exptl. results revealed that the alignment-independent descriptors, electrostatic and steric field descriptors were significantly correlated with the antidiabetic activity of the new derivatives In addition, the new compounds were docked in the active site of DPP-4 in reference to sitagliptin to rationalize the binding modes of the compounds with the amino acid residues of the enzyme. Furthermore, ¹³¹I-compound 4 complex was selected to evaluate the pharmacokinetic behavioral profile of compound 4 and its body organs uptakes alongside its elimination pathway as a representative example for the rest of the analogs. The bio distribution pattern of the tracer proved the selective accumulation of ¹³¹I-substrate in the pancreas and rapid clearance from most of the body organs.

A heterogeneous transition metal-free material, a type of carbon nitride photocatalyst, potassium poly(heptazine imide), was employed to produce sulfonyl chlorides from arenediazonium salts under mild conditions (visible light irradiation, room temperature) with 50-95% yields. The method was suitable for the synthesis of both electron rich and electron deficient compounds and it showed high tolerance toward different functional groups (halides, ester, nitro, cyano groups). Thus, a sustainable photocatalytic alternative to the Meerwein chlorosulfonylation reaction was offered.

Sui, Yan-Fei published the artcilePyrimidinetrione-imidazoles as a Unique Structural Type of Potential Agents towards Candida Albicans: Design, Synthesis and Biological Evaluation, Name: 3-Chlorobenzylchloride, the publication is Chemistry – An Asian Journal (2021), 16(11), 1417-1429, database is CAplus and MEDLINE.

A series of pyrimidinetrione-imidazole conjugates I [R¹ = H, Et, 2-chlorobenzl, etc.] as potentially antifungal agents were developed. Bioassays manifested that I [R¹ = 4-fluorobenzl] exerted favorable inhibition towards C. albicans (MIC=0.002 mM), being 6.5 folds more active than clin. antifungal drug fluconazole (MIC=0.013 mM). Preliminary mechanism research indicated that compound I [R¹ = 4-fluorobenzl] could not only depolarize membrane potential but also permeabilize the membrane of C. albicans. Mol. docking was operated to simulate the interaction mode between mol. I [R¹ = 4-fluorobenzl] and CYP51. In addition, hybrid I [R¹ = 4-fluorobenzl] might form I [R¹ = 4-fluorobenzl]-DNA supramol. complex via intercalating into DNA. The interference of membrane and DNA might contributed to its fungicidal capacity with no obvious tendency to induce the resistance against C. albicans. Conjugate I [R¹ = 4-fluorobenzl] endowed good blood compatibility as well as low cytotoxicity towards HeLa and HEK-293T cells.

Cozzi, Franco published the artcileThrough-space interactions between parallel-offset arenes at the van der Waals distance: 1,8-diarylbiphenylene syntheses, structure and QM computations, SDS of cas: 209919-30-2, the publication is Physical Chemistry Chemical Physics (2008), 10(19), 2686-2694, database is CAplus and MEDLINE.

A model for studying polar-π interactions between arenes spaced at van der Waals distances is developed on the basis of peri-diarylbiphenylenes. A set of 1,8-diarylbiphenylenes is synthesized comprising two Hammett series, one with reference to mesityl ring interactions and the other with reference to pentafluorophenyl ring interactions. X-Ray crystal structures of several derivatives are determined Barriers to rotation of the probe aryl ring are derived from dynamic NMR data and show a trend for the mesityl reference series (ΔG^≠vs. σ°). The model is also used as a test for comparison of modern d. functional methods, including B3LYP, M06-2X and BMK functionals; dispersive effects are seen to be an important factor in the proper theor. treatment of arene interactions.

Rosch, Andrea published the artcileHow Biotransformation Influences Toxicokinetics of Azole Fungicides in the Aquatic Invertebrate Gammarus pulex, Quality Control of 67747-01-7, the publication is Environmental Science & Technology (2016), 50(13), 7175-7188, database is CAplus and MEDLINE.

Biotransformation is a key process that can greatly influence the bioaccumulation potential and toxicity of organic compounds In this study, biotransformation of seven frequently used azole fungicides (triazoles: cyproconazole, epoxiconazole, fluconazole, propiconazole, tebuconazole and imidazoles: ketoconazole, prochloraz) was investigated in the aquatic invertebrate Gammarus pulex in a 24 h exposure experiment Addnl., temporal trends of the whole body internal concentrations of epoxiconazole, prochloraz, and their resp. biotransformation products (BTPs) were studied to gain insight into toxicokinetic processes such as uptake, elimination and biotransformation. By the use of high resolution tandem mass spectrometry in total 37 BTPs were identified. Between one (ketoconazole) and six (epoxiconazole) BTPs were identified per parent compound except for prochloraz, which showed extensive biotransformation reactions with 18 BTPs detected that were mainly formed through ring cleavage or ring loss. In general, most BTPs were formed by oxidation and conjugation reactions. Ring loss or ring cleavage was only observed for the imidazoles as expected from the general mechanism of oxidative ring openings of imidazoles, likely affecting the bioactivity of these BTPs. Overall, internal concentrations of BTPs were up to 3 orders of magnitude lower than that of the corresponding parent compound Thus, biotransformation did not dominate toxicokinetics and only played a minor role in elimination of the resp. parent compound, with the exception of prochloraz.

Jodinskiene, M. published the artcilePeculiarities of two different IAA binding sites functioning in kidney bean hypocotyl cell plasmalemma, Category: chlorides-buliding-blocks, the publication is Biologija (2007), 53(2), 44-47, database is CAplus.

Peculiarities of the interaction of phytohormone indole-3-acetic acid (IAA or auxin) and auxin-binding proteins (ABP) in the plasmalemma of kidney bean (dicot plant) hypocotyl cells according to different physiol. responses to IAA have been studied. Two different IAA binding sites (optimal pH 5.5 and 7.5) were discovered in the plasma-lemma of cells responding to IAA by elongation. The first site is characterized as IAA-receptor mediating cell response to IAA by elongation. It has a structure of the IAA binding site -/-H-R-H-S-C-E-/. This site is not functioning in hypocotyl cells not responding to IAA by elongation. The activity of the second site (optimal pH 7.5) is dependent on IAA transport. Basing on the characteristics of this site, the following suggestions may be made: one residue of histidine and amino acid(s) containing the -SH- group are functioning in this site; the IAA influx inhibitor 3-chloro-4-hydroxyphenylacetic acid (CHPAA) is capable of a very active competition with IAA in the binding site: it reduces IAA-ABP interaction by 92%. These results confirmed that several different ABP may be functioning in the cell and that for each sep. response an individual receptor may be required.
