Summary:Provided is a conjugate precursor for obtaining a more useful antitumor agent by further developing a conventional antibody-drug conjugate. Provided are: an antibody-multidrug conjugate precursor represented by general formula (I) (in the formula, the symbols have the meanings as defined in the specification) or a salt thereof; and a synthetic intermediate thereof or a salt thereof. L'invention concerne un précurseur de conjugué pour obtenir un agent antitumoral plus utile en développant davantage un conjugué anticorps-médicament classique. L'invention concerne : un précurseur de conjugué anticorps-multimédicaments représenté par la formule générale (I) (dans la formule, les symboles ont les significations telles que définies dans la description) ou un sel de celui-ci ; et un intermédiaire synthétique de celui-ci ou un sel de celui-ci. 従来の抗体・薬物コンジュゲートを更に進化させてより有用な抗腫瘍薬を得るためのコンジュゲート前駆体の提供。下記一般式(I):[式中、記号は明細書に記載の意味を有する]で表される、抗体・複数薬物コンジュゲート前駆体またはその塩、およびその合成中間体またはその塩。
