In an embodiment of the invention, a composition for treating a cell population comprises an Affinity Medicant Conjugate (AMC). The medicant moiety can be a toxin including an acylfulvene or a drug moiety. The affinity moiety can be an antibody, a binding protein, a steroid, a lipid, a growth factor, a protein, a peptide or non peptidic. The affinity moiety can be covalently bound to the medicant via a linker. Novel linkers that can be directed to cysteine, arginine or lysine residues based on solution pH allow greater flexibility in preserving and/or generating specific epitopes in the AMC.
在本发明的一个实施方案中,一种用于治疗细胞群的组合物包含一种亲和药剂共轭物(AMC)。药剂分子可以是包括酰化芬在内的毒素或药物分子。亲和剂可以是抗体、结合蛋白、类固醇、脂质、生长因子、蛋白质、肽或非肽。亲和分子可以通过连接体与药物共价结合。新型连接体可根据溶液 pH 值定向连接半胱氨酸、精氨酸或赖氨酸残基,从而更灵活地保留和/或生成 AMC 中的特定表位。
