Two aqua-oxovanadium complexes, viz. [A-VO(H₂O)(sal-L-Leu)] (I) and [VO(H₂O)₂(5-Br-sal-Gly)]·H₂O(II·H₂O ), containing the water ligands in cis- and trans-positions to the oxo group at V-OH₂ distances ranging from 2.008 to 2.228 Å, have been structurally characterized in order to model the apical electron d. feature found in the structures of fungal and algal vanadate-dependent peroxidases. Br K-edge XAS of bromide-treated bromoperoxidase from Ascophyllum nodosum and model compounds (including II·H₂O) has been used to show that the substrate bromide does not bind to active site vanadium but to a light atom, possibly carbon, in its vicinity.

Bazzi, Sakna published the artcileElectrogenerated Sm(II)-Catalyzed CO₂ Activation for Carboxylation of Benzyl Halides, Quality Control of 939-99-1, the publication is Organic Letters (2019), 21(24), 10033-10037, database is CAplus and MEDLINE.

Sm(II)-catalyzed carboxylation of benzyl halides is reported through the electrochem. reduction of CO₂. The transformation proceeds under mild reaction conditions to afford the corresponding phenylacetic acids in good to excellent yields. This user-friendly and operationally simple protocol represents an alternative to traditional strategies, which usually proceeds through the C(sp³)-halide activation pathway.

Markushyna, Yevheniia published the artcileChromoselective Synthesis of Sulfonyl Chlorides and Sulfonamides with Potassium Poly(heptazine imide) Photocatalyst, Quality Control of 939-99-1, the publication is Angewandte Chemie, International Edition (2021), 60(37), 20543-20550, database is CAplus and MEDLINE.

Among external stimuli used to promote a chem. reaction, photocatalysis possesses a unique one-light. Photons are traceless reagents that provide an exclusive opportunity to alter chemoselectivity of the photocatalytic reaction varying the color of incident light. This strategy may be implemented by using a sensitizer capable to activate a specific reaction pathway depending on the excitation light. Herein, we use potassium poly(heptazine imide) (K-PHI), a type of carbon nitride, to generate selectively three different products from S-arylthioacetates simply varying the excitation light and otherwise identical conditions. Namely, arylchlorides are produced under UV/purple, sulfonyl chlorides with blue/white, and diaryl disulfides at green to red light (e.g., S-Ph thioacetate → benzenesulfonyl chloride (93%) under blue light irradiation using HCl in water/MeCN and O₂ as electron acceptor). A combination of the neg. charged polyanion, highly pos. potential of the valence band, presence of intraband states, ability to sensitize singlet oxygen, and multi-electron transfer is shown to enable this chromoselective conversion of thioacetates.

The method of Allen, et al. (CA 52, 10344d) and its modifications for hemoglobin (I) determination are reviewed. The methods are affected by temperature, pH, and ionic concentration of developers, state of equilibrium of the Amberlite IRC-50, amount of I, and oxidation state of the heme in the I applied. By the use of a radioactive tracer technique, differences in the chromatographic behavior of I S and I D and of the ferrihemoglobin cyanide and oxyhemoglobin forms of I F were demonstrated.

Kamenova-Nacheva, Mariana published the artcileSynthesis of ferrocenylmethylidene and arylidene substituted camphane based compounds as potential anticancer agents, HPLC of Formula: 21286-54-4, the publication is New Journal of Chemistry (2017), 41(17), 9103-9112, database is CAplus.

Herein is described the synthesis of (+)-camphor derivatives containing sulfonamide groups, ferrocenylmethylidene or arylidene moieties. The obtained derivatives were tested against seven human cancer cells lines, namely BV-173, K-256a, NB-4, A549, H1299, MCF-7, and MDA-MB231, and two normal human cell lines, HEK293 and HUVEC, to determine their activity against malignant cells. Some of them exhibit IC₅₀ values below 10 μM in at least one of the cancer cell lines. Ferrocenylmethylidene ketone 16 (1-((1S,4S)-3-((E)-ferrocenylmethylidene)-7,7-dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)-N-(tert-butyl)methanesulfonamide) can be outlined as the most potent and selective in the current study (IC₅₀ for cancer cells – up to 4.0 μM; IC₅₀ for HEK293 and HUVEC – 68 and 69 μM, resp.). There is a clear trend showing that the presence of a conjugated ferrocenylmethylidene group is essential for the cytotoxicity, however different sulfonamide substituents and derivatization of the carbonyl group can modify the activity. Thus, this class of compounds could have good prospects for further structural optimization.

Wodtke, Robert published the artcileSynthesis and kinetic characterization of water-soluble fluorogenic acyl donors for transglutaminase 2, Application of 2-Chlorotrityl chloride, the publication is ChemBioChem (2016), 17(13), 1263-1281, database is CAplus and MEDLINE.

Small Glu-containing peptides bearing coumarin derivatives as fluorescent leaving groups attached to the γ-carboxylic acid group of the Glu residue were synthesized and investigated with regard to their potential to act as substrates for transglutaminase 2 (TGase 2). Their synthesis was accomplished by an efficient solid-phase approach. The excellent water solubility of the compounds enabled their extensive kinetic characterization in the context of TGase 2-catalyzed hydrolysis and aminolysis. The influence of the coumarin skeleton’s substitution pattern on the kinetic properties was studied. Derivatives containing 7-hydroxy-4-methylcoumarin (HMC) revealed properties superior to those of their 7-hydroxycoumarin counterparts; analogous amides were not accepted as substrates. Z-Glu(HMC)-Gly-OH, which exhibited the best substrate properties out of the investigated derivatives, was selected for representative kinetic characterization of acyl acceptor substrates and irreversible inhibitors.

Herder, Martin published the artcileImproving the Fatigue Resistance of Diarylethene Switches, Application In Synthesis of 219537-97-0, the publication is Journal of the American Chemical Society (2015), 137(7), 2738-2747, database is CAplus and MEDLINE.

When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the desired high reversibility for many different derivatives To overcome this general problem, we have synthesized and thoroughly investigated the fatigue behavior of a series of diarylethenes, varying the nature of the hetaryl moieties, the bridging units, and the substituents. By anal. of photokinetic data, a quantification of the tendency for byproduct formation in terms of quantum yields could be achieved, and a strong dependency on the electronic properties of the substituents was observed In particular, substitution with 3,5-bis(trifluoromethyl)phenyl or 3,5-bis(pentafluorosulfanyl)phenyl groups strongly suppresses the byproduct formation and opens up a general strategy to construct highly fatigue-resistant diarylethene photochromic systems with a large structural flexibility.

Krymov, Stepan K. published the artcileSynthesis, biological evaluation, and in silico studies of potential activators of apoptosis and carbonic anhydrase inhibitors on isatin-5-sulfonamide scaffold, Product Details of C8H6ClF3, the publication is European Journal of Medicinal Chemistry (2022), 113997, database is CAplus and MEDLINE.

Carbonic anhydrase IX is a promising target for the search for new antitumor compounds with improved properties. Using the mol. hybridization approach, on the basis of structures of a selective carbonic anhydrase IX inhibitor 3 and an activator of apoptosis 2 (1), a series of 1-substituted isatin-5-sulfonamides I [R = benzyl, 2-fluorobenzyl, 3-fluorobenzyl, etc.] were designed and synthesized. The study of the inhibitory activity of isatin-5-sulfonamides showed the ability to inhibit I, II, IX, XII isoforms at nano- and micromolar concentrations Docking of compounds 1-(3,5-Difluorobenzyl)-2,3-dioxoindoline-5-sulfonamide and 1-(2,4-Dichlorobenzyl)-2,3-dioxoindoline-5-sulfonamide into the active site of II and IX carbonic anhydrase isoforms showed the coordination of sulfonamidate anions with zinc cations, as well as a number of addnl. hydrophobic interactions. The trifluoromethylthio derivative2,3-Dioxo-1-(4-((trifluoromethyl)thio)benzyl)indoline-5-sulfonamide suppressed the growth of tumor cells at low micromolar concentrations, maintaining activity on resistant lines and under hypoxic conditions. Immunoblotting of MCF7 cells treated with the 2,3-Dioxo-1-(4-((trifluoromethyl)thio)benzyl)indoline-5-sulfonamide revealed its antiestrogenic activity and ability to activate apoptosis in tumor cells.
