Abstract: The present invention provides compounds of formula I which are capable of inhibition of the activation of hNav1.1 or hNav1.6 sodium channels in neurons. Pharmaceutical compositions comprising these compounds are also provided. Methods for prevention and treatment of neurological disorders, including, for example, seizures and seizure disorders, including Lennox-Gastaut Syndrome, Dravet syndrome, epileptic encephalopathies, autism, Familial hemiplegic migraine (FHM), anxiety disorders, including Post-traumatic stress disorder (PTSD), panic disorder and obsessive-compulsive disorder, neuropathic pain, and Rett syndrome by administration of these compounds are also provided.

Abstract: Methods and reagents for site-selective functionalization of peptides and proteins. The methods most generally involve the reaction of a thioester with hydrazine. Reagents include bifunctional reagents of formula: H2N—NH—CH2-M-L-FG and salts thereof where M is a single bond or a chemical group carrying a non-bonding electron pair, such as —C(O)NR?—, where R? is H, or an alkyl or aryl group; L is an optional linker group as described above; and FG is a functional group having reactivity that is orthongonal to that of the hydrazine group. FG can, among others, be an azide, alkenyl, alkynyl, nitrile (—CN) or triazole group and is preferably an azide group (—N3). Methods and reagents can, for example, be combined with intein-mediated protein splicing to link proteins or fragments thereof to various chemical species or to a surface.
