The invention relates to solid supports useful in medical applications that provide controlled release of drugs, such as peptides, nucleic acids and small molecules. The drugs are covalently coupled to the solid support through a linkage that releases the drug or a prodrug through controlled beta elimination.

The invention relates to conjugates of macromolecular carriers and drugs comprising linkers that release the drug or a prodrug through rate-controlled beta-elimination, and methods of making and using the conjugates.
culture via fluorescence microscopy. In addition, we used Ep to develop a high throughput screen for ERAAP inhibitors, and screened an electrophile library containing 1460 compounds. From this Ep based screen we identified aromatic alkyne-ketone as a lead fragment that can irreversibly inhibit ERAAP activity. We anticipate numerous applications of Ep given its unique ability to image ERAAP within cells
ERAAP 是一种细胞内氨基肽酶,在确定细胞通过 MHC I 类分子展示的肽库中起核心作用,ERAAP 中的功能障碍与多种疾病有关。因此,人们对开发能够在细胞中对 ERAAP 进行成像的探针产生了极大的兴趣。在本报告中,我们提出了一种称为 Ep 的荧光探针,它可以对活细胞中的 ERAAP 活动进行成像。Ep 由 10 个氨基酸的 ERAAP 底物组成,该底物具有与其偶联的供体猝灭剂对,由 BODIPY 和二硝基甲苯组成。ERAAP 裂解后 Ep 的荧光增加了 20 倍,并且能够通过荧光显微镜。此外,我们使用 Ep 开发了 ERAAP 抑制剂的高通量筛选,并筛选了包含 1460 种化合物的亲电试剂库。从这个基于 Ep 的筛选中,我们将芳香族炔酮鉴定为可以不可逆地抑制 ERAAP 活性的先导片段。鉴于 Ep 具有在细胞内成像 ERAAP 的独特能力,我们预计 Ep 将有大量应用。

The preparation and characterization by LCMS of a library of 55 fluorescence- quenched peptides is described. The peptides bear a terminal anthranilamide fluorophore and a penultimate 2,4-dinitrophenyl-L-lysine quencher, and will be used to probe the substrate binding domain of the human blood coagulation enzyme, factor Xa.
A method of screening a sample for the presence of a matrix metalloproteinase employing discriminatory peptide substrates is provided. The method involves providing a peptide substrate of 6-14 amino acid residues containing at least one matrix metalloproteinase cleavage site. The peptide substrate contains Mca as a fluorogenic group and Lys(Dnp) as a quenching group separated by at least four amino acid residues, wherein the peptide substrate is specific for the matrix metalloproteinase of interest. The peptide substrate is combined with a sample containing at least one matrix metalloproteinase to form a mixture. The fluorescence of the mixture is monitored to determine if the matrix metalloproteinase of interest is present.
