Copper tripeptide
(Synonyms: [N2-(N-甘氨酰-L-组氨酰)-L-赖氨酸]铜,GHK-Cu) 目录号 : GC39702
Copper tripeptide (GHK-Cu) 是一种天然存在的三肽，首先从人血浆中分离，但也可以在唾液和尿液中发现。在伤口愈合期间，Copper tripeptide 可以通过蛋白水解从现有的细胞外蛋白质中除去，并且用作炎性和内皮细胞的化学引诱物。Copper tripeptide 可以增加成纤维细胞中胶原蛋白，弹性蛋白，蛋白多糖和糖胺聚糖中信使 RNA 的产生。Copper tripeptide 是皮肤再生中多种细胞途径的天然调节剂。

Copper tripeptide (GHK-Cu), a naturally occurring tripeptide, is first isolated from human plasma, but can be found in saliva and urine. During wound healing, Copper tripeptide may be freed from existing extracellular proteins via proteolysis and serves as a chemoattractant for inflammatory and endothelial cells. Copper tripeptide has been shown to increase messenger RNA production for collagen, elastin, proteoglycans, and glycosaminoglycans in fibroblasts. Copper tripeptide is a Natural Modulator of Multiple Cellular Pathways in Skin Regeneration[1].

Human skin penetration of a Copper tripeptide in vitro as a function of skin layer
Inflamm Res 2011 Jan;60(1):79-86.PMID:20721598DOI:10.1007/s00011-010-0238-9.
Objective and design: Skin retention and penetration by copper applied as glycyl-L-histidyl-L-lysine cuprate diacetate was evaluated in vitro in order to assess its potential for its transdermal delivery as an anti-inflammatory agent. Materials and methods: Flow-through diffusion cells with 1 cm(2) exposure area were used under infinite dose conditions. 0.68% aq. Copper tripeptide as permeant was applied on isolated stratum corneum, heat-separated epidermis and dermatomed skin and receptor fluid collected over 48 h in 4 h intervals using inductively coupled plasma mass spectrometry to analyze for copper in tissues and receptor fluid. Results: The permeability coefficient of the compound through dermatomed skin was 2.43 ± 0.51 × 10(-4) cm/h; 136.2 ± 17.5 μg/cm(2) copper permeated 1 cm(2) of that tissue over 48 h, while 97 ± 6.6 μg/cm(2) were retained as depot. Conclusions: Copper as tripeptide was delivered in potentially therapeutically effective amounts for inflammatory disease.

Materials and methods: Flow-through diffusion cells with 1 cm(2) exposure area were used under infinite dose conditions. 0.68% aq. Copper as a tripeptide was applied on isolated stratum corneum, on heat-separated epidermis and on dermatomed skin. Receptor fluid collected over 48 h in 4 h intervals was analyzed by inductively coupled plasma mass spectrometry for copper in tissues and receptor fluid. Results: The permeability coefficient of the compound through dermatomed skin was 2.43 ± 0.51 × 10(-4) cm/h; 136.2 ± 17.5 μg/cm(2) copper permeated 1 cm(2) of that tissue over 48 h, while 82 ± 8.1 μg/cm(2) of copper were retained there as depot. Conclusions: Applied tansdermally as the tripeptide on human skin ex vivo, copper permeated the skin and was also retained in skin tissue in amounts potentially effective for the treatment of inflammatory diseases.
Effects of topical Copper tripeptide complex on wound healing in an irradiated rat model
Otolaryngol Head Neck Surg 2013 Sep;149(3):384-9.PMID:23744835DOI:10.1177/0194599813492644.
Objectives: To evaluate clinical and immunohistopathological effects of topical glycyl-histidyl-lysine-copper (GHK-Cu) on in vivo irradiated rat wounds. Design: Animal model. Setting: Academic institution. Subjects and methods: After dorsal irradiation and a 28-day recovery period, 2 × 8 cm cranially based dorsal flaps were created in Sprague-Dawley rats. Twice daily GHK-Cu gel (test) or aquaphilic ointment (control) was applied for 10 days. Animals were euthanized, digital images of flaps were taken, and harvested tissues were immunohistochemically stained for a vascular endothelium marker, caveolin-1, and vascular endothelial growth factor (VEGF). Digital image analysis was used for outcome measures. Unpaired t-tests were used for statistical analyses; significance of P < .01 accounted for multiple comparisons. Results: By digital analysis of clinical images, 13 test and 10 control animals showed mean ischemic areas of 5.0 cm(2) (SD = 0.9) for tests and 3.8 cm(2) (SD = 1.1; P = .011) for controls. Whole slide digitized images allowed quantification of caveolin-1-stained blood vessels and VEGF expression in fibroblasts at the interface of healing flaps. Caveolin-1 analyses showed a mean of 209.0 vessels (SD = 111.1) and a mean vessel luminal area of 525.7 um(2) (SD = 191.0) in tests and 207.4 vessels (SD = 109.4; P = .973) and 422.8 um(2) (SD = 109.7; P = .118) in controls. VEGF quantified as the percentage of pixels exceeding a colorimetric threshold, with higher fractions of positive pixels indicating more intense staining, showed a mean intensity score of 0.34 (SD = 0.19) in tests and 0.54 (SD = 0.41; P = .169) in controls. Conclusions: Irradiated dorsal rat flaps treated with topical GHK-Cu gel demonstrated no difference in flap ischemia, blood vessel number or area, or VEGF expression compared to controls.
Effects of topical Copper tripeptide complex on CO2 laser-resurfaced skin
Arch Facial Plast Surg 2006 Jul-Aug;8(4):252-9.PMID:16847171DOI:10.1001/archfaci.8.4.252.
Objective: To evaluate the role of skin care products that contain a Copper tripeptide complex, glycyl-l-histidyl-l-lysine-Cu(2+) (GHK-Cu), in treating carbon dioxide (CO(2)) laser-resurfaced skin. Methods: Patients meeting the inclusion criteria underwent circumoral skin resurfacing using a CO(2) laser at standard settings. Patients were then randomized to receive posttreatment skin regimens with or without GHK-Cu. Evaluations for erythema throughout the posttreatment period were performed using computer software and blinded evaluators. In addition, overall improvement in wrinkles and overall improvement in skin appearance 12 weeks after treatment were assessed. Patients completed a validated questionnaire before and 12 weeks after treatment. Results: Thirteen patients completed the study. Computer analysis and blinded evaluators found no statistically significant differences between groups for earlier resolution of erythema. All the patients experienced significant improvement in wrinkles and overall skin quality, but no differences were found between groups. The results of the questionnaire indicated a significant difference in the posttreatment improvement of overall skin quality for patients using GHK-Cu (P = .04). Conclusions: Copper tripeptide complex (GHK-Cu) skin care products placed on CO(2) laser-resurfaced skin offered no significant reduction or resolution of posttreatment erythema. Objective evaluation found no significant improvement in wrinkles or overall skin quality. However, patient satisfaction was significantly higher for those who used GHK-Cu skin care products after CO(2) laser skin resurfacing.
Effects of Copper tripeptide on the growth and expression of growth factors by normal and irradiated fibroblasts
Arch Facial Plast Surg 2005 Jan-Feb;7(1):27-31.PMID:15655171DOI:10.1001/archfaci.7.1.27.
Objective: To evaluate the effects of Copper tripeptide (GHK-Cu) on the growth and autocrine production of basic fibroblast growth factor, transforming growth factor beta1, and vascular endothelial growth factor by normal and irradiated fibroblasts in a serum-free in vitro environment. Methods: Primary human dermal fibroblast cell lines were established after explantation from intraoperative specimens obtained from patients who had undergone radiation therapy for head and neck cancer. Normal and irradiated fibroblasts were propagated in serum- and growth factor-free media. Treatment groups were exposed to GHK-Cu (1 x 10(-9) mol/L). We measured cell counts and production of basic fibroblast growth factor, transforming growth factor beta1, and vascular endothelial growth factor. Results: Irradiated fibroblasts survived and replicated in serum-free media. The population-doubling times of normal and irradiated fibroblasts exposed to GHK-Cu were faster than those of nontreated controls. Irradiated fibroblasts treated with GHK-Cu doubled at a rate that approximated that of untreated controls, and produced significantly more basic fibroblast growth factor and vascular endothelial growth factor than untreated controls early after GHK-Cu exposure. Conclusions: Irradiated fibroblasts survive and replicate in serum-free media, establishing this model as ideal for evaluating growth factor production in vitro. Copper tripeptide accelerates the growth of normal and irradiated fibroblasts to the point where treated irradiated fibroblasts approximate the population-doubling time of normal controls. An early increase in basic fibroblast growth factor and vascular endothelial growth factor production by GHK-Cu-treated irradiated fibroblasts may improve wound healing.
