A probe for measuring the activity of caspase-1 according to the present disclosure can specifically image cells or tissues where inflammatory response is induced because it is cleaved by reacting specifically with the active caspase-1 enzyme in vivo and in vitro and re-emits fluorescence. The probe for measuring the activity of caspase-1 can be used for various purposes, such as for imaging of cells or tissues where inflammatory response is induced, as a drug carrier, for screening of a drug inhibiting inflammatory response, etc. The probe for measuring the activity of caspase-1 is applicable both in vivo and in vitro, and can be used for various applications such as high-throughput screening for new drug development, early diagnosis of diseases, etc.

The present disclosure relates to a pharmaceutical composition for combination therapy for preventing or treating cancer, which contains a first pharmaceutical ingredient containing a drug conjugate wherein an anticancer agent is bound at one end of an amphiphilic peptide represented by SEQ ID NO 1 and a poloxamer; and a second pharmaceutical ingredient containing an anti-PD-L1 antibody; as active ingredients. The pharmaceutical composition significantly inhibits cancer growth in in-vivo experiments and exhibits an effect of significantly enhancing immunotherapeutic effect by activating immune cells in cancerous tissues. In particular, the pharmaceutical composition for combination therapy according to the present disclosure has superior tumor accumulation efficiency and selectivity as compared to existing anticancer agents, and is very stable with little toxicity to normal tissues other than cancerous tissues.

The present disclosure relates to a glycopeptide targeting cancer cells and a contrast agent kit containing the same. The glycopeptide is one wherein an azide reporting monosaccharide is bound to a substrate peptide. As the substrate peptide is specifically cleaved by cathepsin B in cancer cells, an azide reporting monosaccharide is expressed onto the cell surface via metabolic glycoengineering, thereby providing a target for action as a contrast agent. Accordingly, because the azide is exposed to the cell surface only by cathepsin B, as it is specifically expressed in cancer cells, in particular in metastatic cancer cells, while it is limitedly expressed in normal cells and is hardly excreted out the cells, the cancer cells can be selectively imaged by an azide-specific contrast agent.
