Chemical. CAS 35677-89-5. Formula C12H13NO4. MW 235.24. N-Z-L-Homoserine lactone is a synthetic building block or intermediate used in the synthesis of biological active agents and analogs of bacterial quorum-sensing signaling molecules. N-Z-L-Homoserine lactone is shown to irreversibly inactivate the 3C cysteine proteinase of hepatitis A virus HAV and might be a scaffold for potent cyteine protein inhibtiors. Shown to reduce the lag phase duration LPD and increase the exponential growth rate EGR of three strains of Pseudomonas fluorescens isolated from refrigerated raw milk.

Apexbio Technology LLC HMP Linker 68858-21-9 100g
HMP Linker is an acid-sensitive linker used in solid-phase peptide synthesis (SPPS) It is designed to facilitate the covalent attachment of peptide carboxy-terminal residues to solid-phase resin supports and enables controlled cleavage of synthesized peptides under mildly acidic conditions thereby preserving the structural integrity of sensitive functional groups and peptide termini HMP Linker acts primarily by hydrolyzing upon acid catalysis which allows the intact release of peptides from resin supports Based on these properties HMP Linker holds research potential in peptide therapeutics synthesis and studies requiring mild peptide cleavage conditions
Medchemexpress LLC 4-methylumbelliferyl β-D-glucopyranoside | 18997-57-4 | MFCD00063694 | >98.0% | 338.31 g/mol | C16H18O8 | 500MG
