摘要:Synthesis routes that can be adapted to large scale synthesis of oligoguanidine compounds such as oligoarginine compounds are described which use a perguanidinylation step to convert a group of ω-amino groups to the corresponding guanidinyl groups. These compounds find utility as transport agents. Modified oligoguanidine compounds are also described.

标题:Peptidomimetics and method of synthesis thereof
发明人:NEFZI ADEL
权利人:NEFZI ADEL; THE FLORIDA INTERNATIONAL UNIV BOARD OF TRUSTEES
摘要:The subject invention provides compounds, peptidomimetics, and methods of synthesis thereof. The subject invention provides the synthesis and use of guanidino acids and/or poly guanidino acids not only as vehicles for drug delivery but as toolbox for drug discovery. The peptidomimetic of the subject invention comprises oligo(guanidino acid)s or poly(guanidino acid)s with guanidines as peptide bond surrogates. The incorporation of the guanidine as amide bond surrogates offers significant differences in polarity, hydrogen bonding capability, and acid-base character.

摘要:The rapid deconvolution of complex chemical mixtures, such as combinatorial libraries prepared via solution-phase simultaneous addition of functionalities is demonstrated using HPLC. Libraries containing 25-216 members were screened for biological activity and active libraries are fractionated into discreet pools using preferred reversed-phase HPLC. The entire process can be completed from a single synthesis of 15-50 mg, without the need for fixed positions, serial synthesis, or tagging.
