摘要： Disclosed are β-peptides and β-peptide conjugates that are capable of diffusing or otherwise being transported across the cell membranes of living cells. The β-peptides contain at least six β-amino acid residues, at leastsix of which are preferably β3-homoarginine residues. It has been found that when pharmacologically-active agents are conjugated to these types of β-peptides, the resulting conjugates (also disclosed herein) are also capable of diffusing or otherwise being transported across the cell membranes of living cells, including mammalian cells.

摘要： Compounds represented by the following general formula (I): wherein R1, R2, R3, R4, R5, and R6 independently represent a hydrogen atom, a halogen atom, a C1-6 alkyl group, or a C1-6 alkoxyl group, R7 and R8 independently represent a C1-6 alkyl group or an aryl group which may be substituted, R9 and R10 independently represent a hydrogen atom, a C1-6 alkyl group, or a C1-6 alkoxyl group, and R11 represents a hydrogen atom or a C1-6 alkanoyl group, or salts thereof. The aforementioned compounds are substantially non-fluorescent and react with singlet oxygen under a physiological condition to give a fluorescent substance, and therefore they are useful as agents for measurement of singlet oxygen.
