Novel fluorescent markers of Formula I:
are disclosed herein, wherein X and Y are independently or together absent or are independently selected from
R and R1 are independently selected from H and alkyl; Ar is phenyl or heteroaryl; L is absent or a spacer selected from the group consisting of —NH—; —(CH2)nNH—; —NHSO2—; —(CH2)nNHCO—; -(cycloalkyl)NHCO—; —(CH2)nNHSO2—; -(cycloalkyl)NHSO2—; —CONH(CH2)nNHCO—; —CONH(cycloalkyl)NHCO—; —NHCO(CH2)nNHCO—; —NHCO(cycloalkyl)NHCO—; —(CH2)nSO2NH—; -(cycloalkyl)SO2NH—; —(CH2)nNHCSNH—; -(cycloalkyl)NHCSNH—; —CR═CR1—; —C≡C—; —(CH2)nN═CH—; -(cycloalkyl)N═CH—; —N═CH(CH2)—; —N═CH(cycloalkyl)-;
n is an integer ranging from 1 to 5; F is a fluorophore selected from the group consisting of fluorescein, rhodamine, eosin, thionine, safranin, coumarin, methoxycoumarin, dansyl, BODIPY and BODIPY derivatives; and wherein X, Y and L may be positioned in a 1,3,5; 1,2,3; 1,3,4 or in a 3,4,5 configuration respectively.
