3-(acylamino)glutarimides, a class of broad spectrum chemokine inhibitors, are rapidly hydrolyzed in serum, despite being stable in aqueous solution. Synthesis and high-performance liquid chromatography analysis of the proposed N-acyl-glutamate and -glutamine metabolites establish the enzyme-catalyzed breakdown pathways. In vitro assays suggest that despite their short half-life in vivo, the parent
group has recently developed a novel family of Nα-acylation lysine based derivatives. We introduced long chain acyl groups at the Nα position selectively by a new synthetic route that avoided the process of amino protection and deprotection. Sodium Nα-octanamide lysine (C8), sodium Nα-capramide lysine (C10) and sodium Nα-lauramide lysine (C12) can self-assemble into vesicles spontaneously. As a result
