A series of liquid and photoliquefiable azobenzene (Azo) derivatives (Azo-C-Br) have been synthesized for molecular solar thermal fuels. Each of the liquid and photoliquefiable azo derivatives shows a high degree of isomerization, a fast isomerization rate, a long half-life, an appropriate energy storage density, and a solvent-free "charging" and "discharging" process. The photoliquefied azo derivatives can isomerize upon UV light irradiation at low temperatures to give the "UV-charged" azo ones. Therefore, the phase transition enthalpy is stored simultaneously along with the isomerization enthalpy. The "UV-charged" azo derivatives are capable of releasing heat under the manipulation of blue light.

In addition to oncological applications, poly(ADP-ribose) polymerase (PARP) inhibitors have potential as anti-inflammatory agents. Colon-targeted delivery of PARP inhibitors has been evaluated as a pharmaceutical strategy to enhance their safety and therapeutic efficacy against gut inflammation. Colon-targeted PARP inhibitors 5-aminoisoquinoline (5-AIQ) and 3-aminobenzamide (3-AB) were designed and synthesized by azo coupling with salicylic acid (SA), yielding 5-AIQ azo-linked with SA (AQSA) and 3-AB azo-linked with SA (ABSA).

The discovery of a multi-target scaffold in medicinal chemistry is an important goal for the development of new drugs with different biological effects. Azobenzene is one of the frameworks in medicinal chemistry used for its simple synthetic methods and for the possibility to obtain a great variety of derivatives by simple chemical modifications or substitutions. Phenyldiazenyl-containing compounds show a wide spectrum of pharmacological activities, such as antimicrobial, anti-inflammatory, anti-neurodegenerative, anti-cancer, and anti-enzymatic.

In this study, a polymer gel electrolyte based on polyacrylonitrile was synthesized with varying polymer-to-liquid-electrolyte ratios. DSSCs incorporating a 1:3 ratio showed optimum PV parameters. Choosing this proportion, the effect of incorporating the photoresponsive AZO dye into this polymer electrolyte was studied.

A synthetic strategy of a three-component spiro-pyrrolidine compound based on benzofuran via an [3+2] azomethine ylide cycloaddition reaction is reported herein. Under mild optimal conditions, this reaction can quickly produce potentially bioactive compounds with a wide range of substrates, high yield, and simple operation. The desired products were obtained with a yield of 74-99% and a diastereomeric ratio (dr) of >20:1.

Ensuring everyone enjoys healthy lifestyles and well-being at all ages, Progress has been made in increasing access to clean water and sanitation facilities and reducing the spread of epidemics and diseases. The synthesis of nano-particles (NPs) by using microalgae is a new nanobiotechnology due to the use of the biomolecular (corona) of microalgae as a capping and reducing agent for NP creation. This investigation explores the capacity of a distinct indigenous microalgal strain to synthesize silver nano-particles (AgNPs), as well as its effectiveness against multi-drug resistant (MDR) bacteria and its ability to degrade Azo dye (Methyl Red) in wastewater.
