标题:含硫二氨基酸结构对共价交联共多肽水凝胶的影响
摘要:生物产生的非规范二α-氨基酸以合理的收率和高纯度转化为新的二氮-羧基酸酐(di-Nca)单体.五个不同的二种nca分别用共聚叔丁基-升-谷氨酸nca,以获得能够形成具有变化的密度的交联剂水凝胶的共价交联共聚.比较水凝胶性质和残基结构,发现不同的二-α-氨基酸在交联形成中不相等.值得注意的是,升-Cystine发现相比以产生显著弱凝胶升-Homocystine,升-Cystathionine,和升-Lanthionine,表明升在制备共肽网络时,胱氨酸可能不是最佳的二α-氨基酸选择.二α-氨基酸交联剂还提供不同的化学稳定性,其中二硫键容易被还原降解,硫醚交联对还原稳定.这种响应差异可以提供一种手段来微调多肽生物材料网络的还原敏感性.

摘要:The present invention provides a system and method for assessing a synthetic peptide population including interrogating a population of peptide features in the presence of a receptor having an affinity for a binder sequence. The population of peptide features is synthesized over a plurality of synthesis periods and includes a plurality of control peptide features synthesized to have an amino acid sequence including the binder sequence. The control peptide features include a first feature synthesized beginning with a first one of the synthesis periods, and a second feature synthesized beginning after the first one of the synthesis periods such that synthesis of the second control peptide feature is delayed by at least one synthesis period. The method further includes detecting a signal output characteristic of an interaction of the receptor with the control peptide features, the signal output indicative of the fidelity of synthesis of the population of peptide features.

摘要:Described herein are the one-pot synthesis and characterization of a library of low molecular weight peptoid compounds that are able to form gels at room temperature. The compounds are synthesized from biologically-based starting materials, are biocompatible, and are resistant to degradation by proteases and peptidases. The compounds and gels synthesized therefrom can be used in such applications as tissue engineering, drug delivery, separation of biomolecules, and stimulus-responsive advanced materials

权利人:CIBA GEIGY CORP
摘要:The present invention is directed to the production of an antipathogenic substance (APS) in a host via recombinant expression of the polypeptides needed to biologically synthesize the APS. Genes encoding polypeptides necessary to produce particular antipathogenic substances are provided, along with methods for identifying and isolating genes needed to recombinantly biosynthesize any desired APS. The cloned genes may be transformed and expressed in a desired host organisms to produce the APS according to the invention for a variety of purposes, including protecting the host from a pathogen, developing the host as a biocontrol agent, and producing large, uniform amounts of the APS.
