Disclosed are a new class of a polyphosphazene-platinum(II) conjugate antitumor agent having high tumor tissue selectivity due to its enhanced permeability and retention effect to tumor tissues, and a preparation method (1) thereof, wherein x represents the number of the ethylene oxide repeating unit and is 7, 12, or 16; y is 0, 1 or 2; z represents molar content of polyethylene glycol in the range of 0.5 - 1.5; n represents degree of polymerization of polyphosphazene in the range of 30 - 100; and A-A represents a diamine.
The present invention provides a reagent for introducing a protein or gene into a cell. The reagent of the present invention is, for example, a reagent for introducing a protein or gene into a cell, which comprises a composition comprising a cationic amino acid type lipid represented by the following formula (I)-1:
(wherein in formula (I)-1: L is a single bond, —CONH—, or —S—S—; M
1
is —(CH
2
)
k
— or —(CH
2
CH

O)
k
— (wherein k is an integer between 0 and 14); and m1 and m2 are each independently an integer between 11 and 21 (in this regard, when providing a reagent for introducing a gene into a cell, the case where both m1 and m2 are 15 is excluded)).
