产品描述 Description

[D-Lys3]-GHRP-6 is a highly selective growth-hormone secretagogue receptor (GHSR) antagonist, with an IC50 value of 0.9μM [1]. [D-Lys3]-GHRP-6 induces pronounced smooth muscle contractions in the rat fundus by interacting with 5-HT2B receptors [2]. [D-Lys3]-GHRP-6 has been widely used to alter the metabolic functions and food intake of diabetic mouse models[3].

In vitro, [D-Lys3]-GHRP-6 treatment at 100μM for 48h significantly decreased the cell viability of HECa10 cells [4]. Treatment with 100μM of [D-Lys3]-GHRP-6 for 30 minutes can block the entry and proliferation of HIV-1 virus mediated by CXCR4 in activated peripheral blood mononuclear cells (PBMC)[5]. Treatment with 1μM of [D-Lys3]-GHRP-6 for 24 hours significantly induced apoptosis of dorsal root ganglion (DRG) cells and regulated calcium ion levels[6].

In vivo, [D-Lys3]-GHRP-6 treatment via intraperitoneal injection at a dose of 20nmol/day for 14 days inhibited the growth of tumor volume in the PC3 cell-xenograft mouse model [7]. For 7 consecutive days, intravenous injection twice daily of 6mg/kg dose of [D-Lys3]-GHRP-6 significantly reduced the weight gain of growing pigs, increased the serum non-esterified fatty acids (NEFA) and insulin levels, liver glucose levels, and homeostasis model assessment of insulin resistance index (HOMA-IR) after fasting, and decreased the serum total bile acid (TBA) level[8].

[D-Lys3]-GHRP-6是一种高选择性的生长激素促分泌素受体（GHSR）拮抗剂，IC50值为0.9µM [1]。[D-Lys3]-GHRP-6通过与5-HT2B受体相互作用，可诱导大鼠胃底部产生明显的平滑肌收缩[2]。[D-Lys3]-GHRP-6已被广泛用于改变糖尿病小鼠模型的代谢功能和食物摄入[3]。

在体外，使用100µM的[D-Lys3]-GHRP-6处理48小时，显著降低了HECa10细胞的活力[4]。使用100µM的[D-Lys3]-GHRP-6处理30分钟，可阻断CXCR4介导的HIV-1病毒在活化的外周血单核细胞（PBMC）中的进入和增殖[5]。使用1µM的[D-Lys3]-GHRP-6处理24小时，显著诱导了背根神经节（DRG）细胞凋亡并调节了钙离子水平[7]。

在体内，每日腹腔注射20nmol/day剂量的[D-Lys3]-GHRP-6，持续14天，抑制了PC3细胞异种移植小鼠模型中的肿瘤体积生长[7]。连续7天每日两次静脉注射6mg/kg剂量的[D-Lys3]-GHRP-6，显著减少了生长猪的体重增加，提高了空腹后的血清非酯化脂肪酸（NEFA）和胰岛素水平、肝脏葡萄糖水平以及稳态模型评估的胰岛素抵抗指数（HOMA-IR），并降低了血清总胆汁酸（TBA）水平[8]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

HECa10 cells

Preparation Method

HECa10 cells were cultured in RPMI-1640 medium supplemented with 10% fetal calf serum (FCS) and antibiotics (penicillin 100U/ml, streptomycin 0.1mg/ml) under normal conditions (5% CO2 with 95% humidified air). HECa10 cells (5×103 cells) were plated using 96-well plates and subjected to incubation for 24h in a 5% CO2 incubator. Incubation was followed by treatment with different doses of [D-Lys3]-GHRP-6 (0.1, 1, 10, and 100μM) for 48h and cell viability was measured.

Reaction Conditions

0.1, 1, 10, and 100μM; 48h

Applications

[D-Lys3]-GHRP-6 treatment decreased the cell viability of HECa10 cells in a dose-dependent manner.
Animal experiment [2]:

Animal models

NOD.CB17-Prkdcscid/Arc (NOD/SCID) mice

Preparation Method

1×106 PC3 cells were subcutaneously injected into the left abdomen of NOD.CB17-Prkdcscid/Arc (NOD/SCID) mice. The mice were raised under specific pathogen-free (SPF) conditions, placed in separate ventilated cages, with a room temperature of 20-23℃ and a light cycle of 12 hours of light/12 hours of darkness. When the tumor reached a volume of approximately 100mm3, the mice were divided into two groups. Subsequently, the mice were intraperitoneally injected with 20nmol per mouse of [D-Lys3]-GHRP-6 (n=4) or PBS (control) (n=5) every day for 14 days. The length and width of the subcutaneous tumors were measured twice a week, and the tumor volume was calculated as the formula: tumor volume = (length×width2)/2.

Dosage form

20nmol/day for 14 days; i.p.

Applications

[D-Lys3]-GHRP-6 treatment inhibited the growth of tumor volume in the PC3 cell-xenograft mouse model.
