Abstract: Provided is a pharmaceutical preparation that is suitable for more effectively exhibiting the efficacy of a glutamic acid derivative, which is a GGT-recognizable prodrug, by producing a composition including a glutamic acid derivative capable of rapidly releasing a physiologically active substance by being recognized by GGT, or a pharmacologically acceptable salt thereof; and a block copolymer in which a polyethylene glycol segment is linked to a polyamino acid segment with a hydrophobic group. Particularly, the composition based on a glutamic acid derivative that uses an antitumor compound as a physiologically active substance is capable of effectively accumulating the glutamic acid derivative at a tumor affected area, exhibits a superior effect against tumors, and is capable of suppressing the release of a physiologically active substance in bone marrow tissue where the expression ratio of GGT is low.

Abstract: A physiologically active substance-conjugated block copolymer having enhanced efficacy and/or safety is provided by enhancing the property of penetrating into a target diseased tissue and/or enhancing excretability, compared to known physiologically active substance-conjugated block copolymer, and suppressing sensitization of the physiologically active substance to normal tissues other than a target diseased tissue. Disclosed is a block copolymer including a polyethylene glycol segment connected with a polyamino acid derivative segment conjugated with a physiologically active substance, in which the molecular weight of the block copolymer is from 2 kilodaltons to 15 kilodaltons, and the light scattering intensity of a 1 mg/mL aqueous solution of the physiologically active substance-conjugated block copolymer as measured with a laser light scattering photometer is at least twice or more the light scattering intensity of toluene.
