Apparent Binding Constants (K_eq) of the Complexes of Various Monosaccharides and Compound 1 (7.2 × 10⁻⁵ M in 9:1 DMSO/Phosphate Buffer 60 mM, pH 7.4)^a

	Keq (M−1)
saccharide	calcd values for 1	literature values for phenylboronic acidb
ribose	2400	24
allose	1500
fructose	1100	160
galactose	310	15
altrose	270
glucose	200	4.6
arabinose	120	25

^aValues are the average of three runs rounded to two significant figures. The binding constants taken from the literature were generated in aqueous solution, while those from the current study were from DMSO/buffer solution. The absolute values are thus not directly comparable.
