Summary: Efficient and cheap catalysts are crucial for the application of hydrazine hydrate as a hydrogen source, and nickel-based catalysts have been extensively studied for their excellent performance in hydrazine hydrate decomposition. In this study, a Ni catalyst supported on anatase TiO2 was prepared and characterized. The effects of TiO2 amount and NaOH concentration on the catalyst's activity were investigated. The results showed that the catalyst with 0.2 mmol Ni content and 100 mg nano-TiO2 support exhibited the best catalytic performance. The use of anatase TiO2 support promoted the dispersion of Ni and improved the catalyst's activity.

Summary: This report presents a high throughput UV-Vis spectroscopic method for measuring hydrogen bonding capacity using a pyrazinone sensor. Over 100 titrations were performed on various biologically relevant compounds, enabling the development of a multiple linear regression model that can predict hydrogen bonding affinity from a single measurement. The effectiveness of single point measurements was demonstrated by obtaining hydrogen bond strengths for a set of carboxylic acid bioisosteres.

Summary: A diaminotriazine (DAT)-containing polydiacetylene (PDA-DAT) colorimetric sensor was developed for selective detection of thymine and oligothymidine. PDA-DAT undergoes a color change in the presence of thymine and oligothymidine due to hydrogen bonding interactions, resulting in absorption spectral shift and corresponding color change. The detection limits for thymine and oligothymidine are 12.6 nM and 14.6 nM, respectively. This study provides a foundation for the design of colorimetric sensors for thymine and oligothymidine.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
