additional basic amine groups in the sidechain enhances DNA binding due to electrostatic interactions. Those compounds containing only a single basic benzylic amine bind similarly to DNA. Only the presence of bulky sidechains appears to decrease the DNA interactions in the compounds examined. Although antitumor activity is seen for (1-pyrenylmethyl)amino alcohols, useful antitumor activity in the series

Disclosed is a modular fluorescence sensor having the following general formula:
1
Where Fl is a fluorophore, N is a nitrogen atom, B
d1
and B
d2
are independently selected binding groups, Sp is an aliphatic spacer, and An is an anchor group for attaching the sensor to solid substrates. n=1 or 2, m=1 or 2, x is an integer, and y=1 or 2. The binding groups are capable of binding an analyte molecule to form a stable 1:1 complex. In a preferred embodiment, the B
d1
is R
1
—B(OH)
2
and B
d2
is R
2
—B(OH)
2
. R
1
and R
2
are aliphatic or aromatic functional groups selected independently from each other and B is a boron atom. The present invention also provides methods of synthesizing a modular fluorescence sensor and its use in labeling solid substrates.
An analytical system for detecting a saccharide is provided. The analytical system includes a saccharide sensor attached to a solid substrate and having the formula:
1
Where Z is selected from the group consisting of hydrogen, alkyl groups, an aryl; N is a nitrogen atom; B
d1
and B
d2
are independently selected binding groups, wherein the binding groups are capable of binding an saccharide; Sp is a spacer; An is an anchor group for attaching the sensor to solid substrate; S is the solid substrate, including a bead; and n=1 or 2, m=1 or 2, y=1 or 2, and p is an integer. In one embodiment the saccharide sensor preferentially detects glucose. The invention further provides beads having the saccharide sensor attached thereto and methods of detecting glucose using the system.
