Exploring new inhibitors with good bioavailability and high selectivity for managing type 2 diabetes mellitus (T2DM) and its associated complications is a major challenge for research, academia, and the pharmaceutical industry. Protein tyrosine phosphatase-1B (PTP1B) arose as an important negative regulator in insulin signaling pathways associated with metabolic disorders, including T2DM and obesity. Novel neutral compounds with a benzene-sulfonamide scaffold were designed and synthesized based on structural- and ligand-based drug design strategies for fragment growth.

Background: The self-etch adhesive system modifies but does not completely remove the smear layer, leading to the weakening of the bond strength due to the formation of a hybridized layer. Smear-layer deproteinization with papain enzyme partially removes the smear layer, and increases the bond strength with self-etch adhesive. The aim was to develop a deproteinizing agent with a high papain enzyme concentration to enhance dentin bonding with self-etch adhesives.

VEGFR2 inhibition has been established as a therapeutic approach for managing cancer. A series of curcumin-based analogues were designed, synthesized, and screened for their anticancer activity against MCF-7 and HepG-2 cell lines and WISH normal cells. Compounds 4b, 4d, 4e, and 4f showed potent cytotoxicity against MCF-7 with IC values of 0.

Article Synopsis
  • The study investigates the anti-cancer effects of phthalimide-1,2,3-triazole compounds with sulfonamide elements on MCF-7 (breast) and PC3 (prostate) cancer cells.
  • Several compounds were created using an efficient click synthesis method, showing promising results with some compounds exhibiting significant cytotoxicity against MCF-7 cells.
  • Notably, compound 6c showed the highest effectiveness, causing cell death and disrupting the cell cycle in MCF-7 cells, suggesting it could be a potential breast cancer treatment.

Article Synopsis
  • Nuciferol C (NC) is a newly identified dimer of nuciferol B (NB), characterized using advanced spectroscopy techniques and high-resolution mass spectrometry.
  • NC demonstrates cytotoxic effects against colon cancer cells, significantly reducing the expression of key proteins associated with cancer proliferation and inflammation.
  • The study also reveals NC's antiviral properties against herpes simplex virus type 1 (HSV-I) and involves extensive computational analysis to investigate its electronic properties and interactions with HSV-I target proteins.
