Nella ricerca scientifica, questo composto viene studiato come composto modello per la chimica di coordinazione dei complessi peptide-metallo e come standard di riferimento in ambito analitico. Il prodotto \u00e8 offerto come formulazione acquosa pronta all'uso da 35 ml, esclusivamente per scopi di laboratorio e di ricerca.<\/p>\n<h2>Cos'\u00e8 AHK-Cu?<\/h2>\n<p>AHK-Cu \u00e8 un tripeptide sintetico con la sequenza alanina-istidina-lisina (Ala-His-Lys) a cui \u00e8 coordinato uno ione rame(II); nella nomenclatura cosmetica, il composto \u00e8 noto come tripeptide di rame-3. Il sito di legame per lo ione metallico \u00e8 formato da tre atomi di azoto donatori che la catena presenta in una disposizione planare: il gruppo \u03b1-amminico all'N-terminale, l'atomo di azoto ammidico del primo legame peptidico e l'imidazolo dell'istidina. La catena laterale basica della lisina rimane al di fuori di questa disposizione e garantisce una buona solubilit\u00e0 in acqua. Ci\u00f2 che distingue AHK-Cu all'interno di questa classe di sostanze \u00e8 una piccola differenza strutturale: all'N-terminale, \u00e8 presente un'alanina al posto della glicina che si trova nel tripeptide di rame pi\u00f9 studiato. Questo gruppo metilico aggiuntivo rende il composto un modello ideale per la questione di come una singola sostituzione accanto all'istidina coordinante influenzi l'affinit\u00e0 per il rame.<\/p>\n<p>In research models, the complex is primarily studied as a carrier and donor of copper: in vitro, under defined conditions, the coordinated ion can be transferred to competing ligands or to copper-dependent enzymes such as lysyl oxidase and superoxide dismutase. Additionally, the copper(II) center makes the formulation easy to monitor spectroscopically: alongside the UV absorption of the imidazole, a weak dd transition occurs in the visible region, which explains the bluish tint and makes the integrity of the complex measurable. In cell-free systems and cell culture models, copper homeostasis and VEGF-mediated signaling are further investigated. Consequently, AHK-Cu is used as a model compound and reference substance within scientific research.<\/p>\n<h2>Aree di ricerca<\/h2>\n<p>In a laboratory context, AHK-Cu occurs in the following research areas, among others:<\/p>\n<ul>\n<li>Bioinorganic coordination chemistry: stability constants, stoichiometry and geometry of copper(II) tripeptide complexes.<\/li>\n<li>Structure-activity relationship study in which the N-terminal amino acid is varied.<\/li>\n<li>Enzymological research into copper-dependent enzymes, including lysyl oxidase and superoxide dismutase.<\/li>\n<li>Cell culture models for copper homeostasis, oxidative balance, and VEGF-mediated signaling.<\/li>\n<li>Sviluppo e validazione di metodi analitici (HPLC, UV-vis, LC-MS) utilizzando la formulazione come materiale di riferimento.<\/li>\n<li>Formulation and stability studies of metallopeptides in aqueous matrix.<\/li>\n<\/ul>\n<p>Ciascuna di queste applicazioni prevede ricerche controllate in laboratorio o su modelli preclinici.<\/p>\n<h2>AHK-Cu Serum in our research assortment<\/h2>\n<p>Within our range, this product falls under the category of ready-to-use aqueous investigational formulations in vial form. While this formulation focuses on metal coordination and the influence of a single amino acid substitution thereon, other components within the same product line have been specifically chosen to cover peptide receptor interactions or enzymatically mediated targets. These products share the aqueous serum base and vial packaging, but differ fundamentally in molecular class and investigated mechanism.<\/p>\n<h2>Specifiche<\/h2>\n<table>\n<thead>\n<tr>\n<th>Specifiche<\/th>\n<th>Valore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Campione<\/td>\n<td>AHK-Cu (alanyl-L-histidyl-L-lysine, copper(II) complex)<\/td>\n<\/tr>\n<tr>\n<td>Sinonimi<\/td>\n<td>copper tripeptide-3; Cu-AHK<\/td>\n<\/tr>\n<tr>\n<td>Sequenza<\/td>\n<td>Ala-His-Lys<\/td>\n<\/tr>\n<tr>\n<td>Numero CAS<\/td>\n<td>682809-81-0<\/td>\n<\/tr>\n<tr>\n<td>Formula molecolare \/ peso<\/td>\n<td>C<sub>15<\/sub>H<sub>24<\/sub>ClCuN<sub>6<\/sub>O<sub>4<\/sub> \/ 451.39 Da (monohydrochloride)<\/td>\n<\/tr>\n<tr>\n<td>PubChem CID<\/td>\n<td>168431292<\/td>\n<\/tr>\n<tr>\n<td>Classe<\/td>\n<td>Metallopeptide; complesso di rame(II) di un tripeptide<\/td>\n<\/tr>\n<tr>\n<td>Forma<\/td>\n<td>Siero acquoso con conservante<\/td>\n<\/tr>\n<tr>\n<td>Contenuto per bottiglia<\/td>\n<td>35 ml<\/td>\n<\/tr>\n<tr>\n<td>Magazzinaggio<\/td>\n<td>Conservare in un luogo fresco e al riparo dalla luce diretta.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Forma, manipolazione e stoccaggio<\/h2>\n<p>The product is supplied as a ready-to-use aqueous formulation of 35 ml in a vial. No solid needs to be weighed: the active substance is already stabilized in the matrix, together with a preservative that inhibits microbial growth. The liquid has the bluish tint characteristic of copper(II) peptides, which comes from the coordinated metal ion.

Copper(II) complexes are sensitive to light, heat, and oxidative conditions, more so in aqueous matrix than in dry form. Handle the product with standard laboratory precautions: work cleanly, use appropriate personal protective equipment, and prevent cross-contamination. Keep the packaging out of reach of unauthorized persons.<\/p>\n<h2>Composizione e risultati di laboratorio<\/h2>\n<p>The AHK-Cu active ingredient in this formulation is offered with a controlled purity of \u2265 99% (HPLC).
