    Abstract: Provided are the following compound and a fluorescently labeled biological substance having this fluorescent compound. X represents CR7 or N.
    R1 to R7, Q1, and Q2 represent a hydrogen atom, a halogen atom, a cyano group, or a group represented by Formula (A), and adjacent substituents may form a ring structure.
    However, at least one of R3, R4, R7, Q1, or Q2 contains, as a hydrophilic group, at least one of a carboxy group or a salt thereof, a sulfo group or a salt thereof, a phosphono group or a salt thereof, an onio group, or a polyamino acid residue, where at least one of Q1 or Q2 represents an alkyl group.

    Abstract: An object of the present invention is to provide a liposome and a liposome composition in which release of a drug in blood is suppressed during accumulation of the liposome and the liposome composition in a target site such as a tumor and the drug is rapidly removed after the liposome and the liposome composition are sufficiently accumulated. According to the present invention, there is provided a liposome containing at least a phospholipid to which a hydrophilic polymer is bonded, a phospholipid having a negative charge within a range of a pH of 6 to 8, and a phospholipid which is electrically neutral within a range of a pH of 6 to 8, in which an average carbon chain length of the phospholipid to which the above-described hydrophilic polymer is bonded is shorter than an average carbon chain length of the above-described phospholipid which is electrically neutral within a range of a pH of 6 to 8.

    Abstract: Provided are any one of the following fluorescent compounds and a fluorescent labeled biological substance having this fluorescent compound. X represents CR5 or N, and R1 to R7, Q1, Q2, L1, and L2 each represent a specific group.
    a ring β1 and a ring β2 are a 5- to 8-membered ring,
    At least one of R1 to R7, L1, L2, Q1, or Q2 has a specific hydrophilic group.
    However, in a case where the ring β1 and the ring β2 are a 6-membered ring, and L1 and L2 are an arylene group, R5 is not an aryl group substituted with a linear alkyl group having 18 or more carbon atoms. In addition to the regulation of the ring β1, the ring β2, L1, and L2, in a case where R5 has a substituent having a dipyrromethene boron complex structure, the dipyrromethene boron complex structure has a structure in which a dipyrromethene skeleton is coordinately bonded to a boron atom in the tridentate or tetradentate coordination.
