Pal-KTTKS is a lipidated pentapeptide consisting of a fragment of the type I collagen C-terminal propeptide conjugated to palmitic acid .1 It increases collagen production in human corneal and dermal fibroblasts when used at concentrations of 0.002, 0.004, and 0.008 wt%.2 Following topical administration, pal-KTTKS (50 μg/cm2) is found in the stratum corneum, epidermis, and dermis of isolated hairless mouse skin.1 It can self-assemble into flat tapes and extended fibrillar structures.3 Pal-KTTKS has been detected in anti-wrinkle creams.4 |1.

Relamorelin (RM-131) acetate is a pentapeptide ghrelin analog that acts as a selective agonist for the ghrelin growth hormone secretagogue receptor (GHSR). It exhibits a high affinity for the GHS-1a receptor, with a Ki value of 0.42 nM. Notably, Relamorelin acetate can cross the blood-brain barrier and target the central nervous system. This compound effectively increases growth hormone levels and promotes faster gastric emptying. Due to these properties, Relamorelin acetate holds promise for its potential applications in research related to cachexia, gastroparesis, and gastric intestinal dysmobility disorders [4] [5].

Relamorelin (RM-131) TFA，一种生长素类似物，是一种选择性的生长素释放肽 生长激素促分泌素受体 (GHSR) 激动剂，对GHS-1a 受体的Ki 值为 0.42 nM。Relamorelin TFA 是一种五肽，具有中枢渗透性。Relamorelin TFA 增加生长激素水平，加速胃排空，具有用于恶病质、胃轻瘫和胃 肠运动障碍研究的潜力。
