This critical review highlights recent advances in the structurally modified (thio)urea-based receptors for anion complexation and sensing. Modifications of the (thio)urea structure are aimed at a better anion binding in terms of higher binding constant, anion selectivity and feasibility. Major (thio)urea receptors are reviewed as N-alkyl, N-aryl and(More)
The fluoroquinolone moxifloxacin has potent activity against Mycobacterium tuberculosis and has been recommended by the guidelines for the treatment of pulmonary tuberculosis (TB). Monotherapy is not recommended by the guidelines and only a few studies have evaluated the efficacy and safety of moxifloxacin plus standard first-line therapy in treating TB.(More)

Developing cavity-based supramolecular hydrogels is in its infancy because not many such hydrogelators are available. Reported herein is our creation of rigid cavitand cyclotriveratrylene (CTV) based hydrogelators from the molecular backbones of CTVs that were in limited cases shown to form organogels. For doing so deprotonable -COOH or protonable -NH(2)(More)
