Several new amides and anilides of alpha-aziridinyl-beta-/p-chlorobenzoyl/-propionic acid were synthetized. The beta-/p-chlorobenzoyl/-acrylic acid 2 was used as the substrate. This compound was converted by reaction with appropriate amine into amides and anilides of beta-/p-chlorobenzoyl/-acrylic acid (3-10). These compounds react with ethylenoimine giving appropriate amides and anilides of alpha-aziridinyl-beta-/p-chlorobenzoyl/-propionic acid (11-18). When pharmacologically analyzed, they appeared to possess marked immunotropic activity. The derivatives in question modulated both humoral as well as cellular immune response, the effect being related to the type of substitutent in the amide group.

Introduction: Oxidative stress is an important cause of acetaminophen (APAP)-induced liver injury (AILI). Sakuranetin (Sak) is an antitoxin from the cherry flavonoid plant with good antioxidant effects. However, whether sakuranetine has a protective effect on APAP-induced liver injury is not clear.

The emergence of green chemistry and engineering principles to enforce sustainability aspects has ensured the prevalence of green solvents and green processes. Our study addresses this quest by exploring drug delivery applications of hydrophobic deep eutectic solvents (DESs) which are alternative green solvents. Initially, this work showcases the hydrophobic drug solubilization capabilities of a natural hydrophobic DES, menthol, and decanoic acid.

Background: Appendicectomy is a common procedure in children. Regional anaesthesia helps reduce requirements for opioids and hospital stay and enhances recovery. Laparoscopic-assisted Transversus Abdominus Plane block (L-TAP) was shown to be efficient and potentially superior to port site infiltration (PSI); however, this was not previously studied in paediatric appendicitis.

Background: The use of intraoperative intra-articular morphine has been suggested to lower postoperative pain scores and opioid use. We sought to evaluate the effectiveness of intra-articular morphine with 0.75% ropivacaine when compared to the use of ropivacaine alone.
