  • Publication number: 20150309040
    Abstract: A library of novel amino-triazolyl-BODIPY compounds is described. Particular compounds of the library serve as selective fluorescent probes Human Serum Albumin (HSA) and for live primary neurons. The fluorescent probe for HSA binds uniquely and specifically to the fatty acid site 1 of HSA, and thus proves a valuable and unique probe for drugs that bind to such a site on HSA. Methods of synthesis for the library compounds are also described.
