Here we report the synthesis of a series of taurine substituted sulfonamide derivatives 1-29 having the ureido moiety installed at the tail section as selective inhibitors of the tumor associated human (h) Carbonic Anhydrase (CA; EC 4.2.1.1) IX and XII. The series was deeply investigated for their kinetic features which demonstrated a strong dependence on the ureido moiety. High resolution X-ray crystallographic investigation on selected ligand adducts complexed with hCA II and hCA IX-mimic revealed a strong correlation between the ureido moiety and the amino acid residues Q92 and Q67 in both the hCA II and hCA IX-mimic, contributing to highly stabilized ligand-protein complex.

Excessive reactive oxygen and nitrogen species (RONS) accumulation in joints are significant variables that affect the course of rheumatoid arthritis (RA). Scavenging of RONS to remodel macrophage homeostasis is a potentially powerful treatment for RA. Here, a visualized "nanosweeper" by functionalizing ultrasmall Gd/FeO nanoparticles with thiol-polyethylene glycol-phosphoric acid and 2-(3-(2-aminophenyl)ureido) ethyl methacrylate hydrochloride (APUEMA), namely GIA NPs, can simultaneously scavenge both nitric oxide (NO) and reactive oxygen species (ROS), as well as enhance magnetic resonance imaging (MRI) for the diagnosis and therapy of RA.

Human skin is essential for perception, encompassing haptic, thermal, proprioceptive, and pain-sensing functions through ion movement. Additionally, it is mechanically resilient and self-healing for protection. Inspired by these unique properties, researchers have attempted to develop stretchable, self-healing sensors based on ion dynamics.

Artificial water channels (AWCs) have been extensively explored to mimic natural proteins, which enables to effectively transport water while blocking ions. As one of the first AWCs, self-assembled I-quartets (HCx) have showcased high water-permselectivity that can be enhanced by improving their distribution and stability within membrane. The use of long alkyl chains (n>8) is constrained by their low solubility and aggregation.

We synthesized herein 16 compounds (SUT1-SUT16) as potential carbonic anhydrase (CA) inhibitors utilizing the tail-approach design. Based on this strategy, we connected benzenesulfonamide, the zinc-binding scaffold, to different urea moieties with the 1,3,4-thiadiazole ring as a linker. We obtained the target compounds by the reaction of 4-(5-amino-1,3,4-thiadiazol-2-yl)benzenesulfonamide with aryl isocyanates.
