    • The invention provides a method for making a selenium-carrier conjugate by covalently attaching (i) an organic selenium compound selected from the group consisting of RSeH, RSeR, RSeR', RSeSeR and RSeSeR', wherein R and R' are each an aliphatic residue containing at least one reactive group selected from the group consisting of aldehyde, amino, alcoholic, carboxylic, phosphate, sulfate, halogen or phenolic reactive groups and combinations thereof, to (ii) a carrier having a constituent capable of forming a covalent bond with said reactive groups of said selenium compound to produce a selenium-carrier conjugate which is capable of specific attachment to a target site. The carrier may be a protein, such as an antibody specific to a bacteria, virus, protozoa, or cell antigen, including without limitation, cell surface antigens, a peptide, carbohydrate, lipid, vitamin, drug, lectin, plasmid, liposome, nucleic acid or a non-metallic implantable device, such as an intraocular implant or a vascular shunt. The attachment of selenium compounds of the configurations described above to carriers when presented to either endogenous thiols, such as glutathione which occurs in all aerobic living cells, or exogenous thiols, such as glutathione or cysteine, produces superoxide (O.sub.2..sup.-), hydrogen peroxide, the hydroxyl radical (.OH) and other cytotoxic reactive oxygen species so as to collectively form a localized free radical pharmacology based upon the catalytic selenium anion, RSe.sup.31.
    • 本发明提供了通过共价连接(i)选自RSeH,RSeR,RSeR',RSeSeR和RSeSeR'的有机硒化合物来制备硒 - 载体缀合物的方法,其中R和R'各自为脂族残基 含有至少一个选自醛,氨基,醇,羧酸,磷酸酯,硫酸酯,卤素或酚反应性基团的反应性基团及其组合,(ii)具有能与所述化合物形成共价键的成分的载体 所述硒化合物的反应性基团产生能够特异性附着于靶位点的硒 - 载体缀合物。 载体可以是蛋白质,例如细菌,病毒,原生动物或细胞抗原特异的抗体,包括但不限于细胞表面抗原,肽,碳水化合物,脂质,维生素,药物,凝集素,质粒,脂质体,核酸 酸或非金属可植入装置,例如眼内植入物或血管分流装置。 当呈现给所有需氧活细胞中发生的内源性硫醇,如谷胱甘肽或外源硫醇,如谷胱甘肽或半胱氨酸时,上述构型的硒化合物与载体的连接产生超氧化物(O2-),过氧化氢 ,羟基自由基(.OH)和其他细胞毒活性氧,以共同形成基于催化硒阴离子RSe的局部自由基药理学。
