Luminescent MOFs Based on Thiazolo[5,4-d]thiazole as a Chemosensor for the Detection of Environmental Contaminants

Luminescent metal-organic frameworks (LMOFs) are considered special candidates for the sensation and detection of particular analytes. Thiazolo[5,4-d]thiazoles (TTZs) are an ideal type of heterocycles for fluorophores with π-bridge moieties demonstrating structure-function characteristics. LMOFs with excellent sensing properties can be constructed by incorporating heterocyclic aromatic thiazolo[5,4-d]thiazole into the framework.

The Effect of Nano-Encapsulated Orlistat on Prostate Cancer: An In vitro Study

Background: The targeted inhibition of fatty acid synthase (FASN) by Orlistat, a potent FASN inhibitor, has been shown to block tumor proliferation and induce apoptosis in cultured tumor cells. Since Orlistat is insoluble, its solubility in blood circulation is limited. Cancer nanotherapeutics are rapidly progressing and are being implemented to solve several limitations of conventional drug delivery systems.
