Long-acting compstatin analogs comprising a clearance-reducing moiety attached to two compstatin analog moieties, each compstatin analog moiety comprising a cyclic peptide extended by a lysine residue or a sequence comprising a lysine residue at the N-terminus, C-terminus, or both, wherein the lysine residue is separated from the cyclic portion of the peptide by a rigid or flexible spacer comprising an oligo(ethylene glycol) moiety, the clearance reducing moiety comprises a linear polymer, wherein each end of the linear polymer is linked to one of the compstatin analog moieties by way of a carbamate, wherein (i) the spacer comprises —(CH2)m— and —(O—CH2-CH2—)n joined covalently, wherein m is between 1 and 10 and n is between 1 and 10; and/or (ii) the spacer comprises 8-amino-3,6-dioxaoctanoic acid (AEEAc) or 11-amino-3,6,9-trioxaundecanoic acid.
长效氯司他丁类似物,包括一个连接到两个氯司他丁类似物分子上的清除率降低分子,每个氯司他丁类似物分子包括一个由赖氨酸残基延伸的环状肽,或一个在N-末端、C-末端或两者处均包括赖氨酸残基的序列,其中赖氨酸残基通过一个由低聚(乙二醇)分子组成的刚性或柔性间隔物与肽的环状部分隔开、清除还原基团包括线性聚合物,其中线性聚合物的每一端通过氨基甲酸酯与其中一个康司他丁类似物基团相连,其中(i)间隔物包括共价连接的-(CH2)m-和-(O-CH2-CH2-)n,其中m在1和10之间,n在1和10之间;和/或 (ii) 中间体包括 8-氨基-3,6-二氧杂辛酸(AEEAc)或 11-氨基-3,6,9-三氧杂十一烷酸。
