A new 1,8-diaminonaphthalene based ratiometric and highlyselectivecolorimetric “off-on” type of fluorescent probe, receptor 2 has been designed and synthesized that senses only Cu2+ among the other heavy and transition metal ions examined on the basis of internal charge transfer (ICT). The visual sensitivity of the receptor 2 is remarkable, showing dual color changes from colorless (receptor) to
The invention relates to novel compounds that are inhibitors of peptidyl deformylase (PDF). The compounds are useful as antimicrobials and antibiotics. The compounds of the invention display selective inhibition of peptidyl deformylase versus other metalloproteinases such as MMPs. Methods of preparation and uses of the compounds are also disclosed.
