Pramod Charpe, Vaibhav;Gupta, Mahima;Chu Hwang, Kuo research published 《 Visible-Light-Induced Oxidative α-keto-Dichlorination of Arylalkynes by CuCl₂ at Room Temperature》, the research content is summarized as follows. A visible light-induced oxidative α-keto-dichlorination of terminal and internal aryl alkynes was developed to form dichloroacetophenones (DCAPs) and dichlorophenyl-acetophenones (DCPAPs), resp., by using CuCl₂ as a photoredox catalyst in the presence of air at room temperature (without using any exogenous photocatalyst). Here, photoexcited CuCl₂ underwent ligand-to-metal charge transfer to generate a Cl radical, which readily added to the alkynes to form DCAPs or DCPAPs in the presence of O₂. This α-keto-dichlorination reaction is a green and mild protocol as it produced water as the only byproduct. Moreover, the evaluation of green chem. metrics indicated that the E-factor (mass of wastes/mass of products) of the current α-keto-chlorination method is around 10.1 times lower than that of a literature-reported photochem. method. The Eco Scale value (score 55, which on a scale of 0-100 indicates an acceptable synthesis) signifies that this process is simple, highly efficient, eco-friendly, and cost-effective.

Pradhan, Tapas R.;Paudel, Mukti;Feoktistova, Taisiia;Cheong, Paul Ha-Yeon;Park, Jin Kyoon research published 《 Silaborative Assembly of Allenamides and Alkynes: Highly Regio- and Stereocontrolled Access to Bi- or Trimetallic Skipped Dienes》, the research content is summarized as follows. A highly stereo- and regiocontrolled multicomponent approach to skipped 1,4-dienes decorated with one boryl and two silyl functionalities, XNR¹CH:C(Bpin)CH₂CR²:CHSiMe₂Ph (X = sulfonyl, acyl; R¹ = benzyl, alkyl; R² = silyl, aryl, alkyl, carboxy) is described, comprising three-component reaction of allenamides XNR¹CH:C:CH₂ with alkynes R²CCH and silylborane Me₂PhSiBpin, catalyzed by Pd₂(dba)₃. This Pd-catalyzed atom-economical union of allenamides, alkynes, and Me₂PhSiBpin (or Et₃SiBpin) proceeds without the use of phosphine ligands, instead relying on chelation through the internal amide group of the allenamide sulfonyl. A variety of alkynes, including those derived from complex bioactive mols., can be efficiently coupled with allenamides and Me₂PhSiBpin in good yields and with excellent selectivity. The synthetic potential was demonstrated through multiple valuable chemoselective transformations, establishing new disconnections for functionalized dienes. D. functional theory calculations revealed that the reaction first proceeded through borylation of the allenamide, followed by silylation of the alkyne and then reductive elimination, which convergently assemble the skipped 1,4-diene.

Photophys. characterization and photostability studies were performed, where both dyes showed favorable photostability and the PEGylated fluorinated bacteriochlorin presented good singlet oxygen quantum yield, showing potential to use as a photosensitizer for PDT (photodynamic therapy). Addnl., the free-base PEGylated phthalocyanine displayed reasonably high Stokes shift, suggesting high potential to use in optical imaging.

Petko, Filip;Galek, Mariusz;Hola, Emilia;Popielarz, Roman;Ortyl, Joanna research published 《 One-Component Cationic Photoinitiators from Tunable Benzylidene Scaffolds for 3D Printing Applications》, the research content is summarized as follows. This paper describes a series of novel benzylidene scaffold-based iodonium salt one-component photoinitiators containing double bonds and dialkylamino groups synthesized in one step via classical aldol condensation reactions. Systematic investigations of structure-activity relationships were performed via quantum-chem. calculations and exptl. tests. New salts can efficiently decompose under irradiation from UV to visible regions of the spectrum. The design of new iodonium salts is described, followed by a description of properties of photoinitiators prepared in this way. All presented salts were characterized in terms of their spectral properties (UV-vis spectroscopy), ability to photodecompose (steady-state photolysis), cationic polymerization of the vinyl monomer, and epoxide monomer photoinitiation (quantum efficiency of acid generation and real-time Fourier-transform IR measurements) as well as their proposed application in 3D printing. New benzylidene iodonium salts can photoinitiate the polymerization of vinyl ethers and epoxy monomers under LED@365 and LED@405 irradiation Investigated compounds can simultaneously initiate and monitor the polymerization process according to the change of fluorescence during the photocuring process. Formulations before photopolymerization do not exhibit fluorescence, during the photopolymerization process fluorescence is “turning on”. This phenomenon might be used to monitor photopolymerization in an “online” manner.

Here we provide a comprehensive kinetic pharmacol. comparison of clin. relevant μ-opioid receptor agonists, including the novel biased agonist oliceridine (TRV130) which is in clin. trial for pain management. We demonstrate that the bias profile observed for the selected agonists is not time-dependent and that agonists with dramatic differences in their binding kinetic properties can display the same degree of bias. Binding kinetics analyses demonstrate that buprenorphine has 18-fold higher receptor residence time than oliceridine. This is thus the largest pharmacodynamic difference between the clin. approved drug buprenorphine and the clin. candidate oliceridine, since their bias profiles are similar. Further, we provide the first pharmacol. characterization of (S)-TRV130 demonstrating that it has a similar pharmacol. profile as the (R)-form, oliceridine, but displays 90-fold lower potency than the (R)-form. This difference is driven by a significantly slower association rate. GRK2 and GRK5 overexpression greatly increased μ-opioid receptor internalization induced by morphine, but only had modest effects on buprenorphine and oliceridine-induced internalization. Overall, our data reveal that the clin. available drug buprenorphine displays a similar pharmacol. bias profile in vitro compared to the clin. candidate drug oliceridine and that this bias is independent of binding kinetics suggesting a mechanism driven by receptor-conformations.
