The present invention relates to novel peptides acting as hepcidin mimetics, as well as analogues and derivatives thereof. The invention further relates to compositions comprising the peptides of the present invention, and to the use of the peptides in the prophylaxis and treatment of hepcidin-associated disorders, including prophylaxis and treatment of iron overload diseases such as hemochromatosis, iron-loading anemias such as thalassemia, and diseases being associated with ineffective or augmented erythropoiesis, as well as further related conditions and disorders described herein.

Introduction of lipoaminoacid (LAA), Lys-palmitoyl, and cationization into a series of galanin analogues yielded systemically active anticonvulsant compounds. To study the relationship between the LAA structure and anticonvulsant activity, orthogonally protected LAAs were synthesized in which the Lys side chain was coupled to fatty acids varying in length from C8 to C18 or was coupled to a monodispersed
将脂氨基酸 (LAA)、Lys-棕榈酰和阳离子化引入一系列甘丙肽类似物,产生具有全身活性的抗惊厥化合物。为了研究 LAA 结构与抗惊厥活性之间的关系,合成了正交保护的 LAA,其中 Lys 侧链与长度从 C 8到 C 18不等的脂肪酸偶联,或与单分散聚乙二醇 PEG 4偶联。全身给药后,测定了甘丙肽受体亲和力、血清稳定性、亲脂性 (log D ) 和每种新合成类似物在 6 Hz 癫痫小鼠模型中的活性。各种 LAA 或 Lys 的存在(MPEG 4) 不影响修饰肽的受体结合特性,但它们的抗惊厥活性变化很大并且通常与它们的亲脂性相关。我们的结果表明,改变与带正电荷的氨基酸残基相邻的 LAA 残基的长度或极性可以有效地调节甘丙肽类似物的抗癫痫活性。
