The subject invention provides compounds having the structure: wherein R1 is H, OH, a photoactivatable moiety, a fluorescent moiety, or a radioactive moiety; R2 is H, OH, a photoactivatable moiety, a fluorescent moiety, or a radioactive moiety; R3 is H or OH; R4 is H, OH, a photoactivatable moiety, a fluorescent moiety, or a radioactive moiety; and wherein at least one of R1, R2, R3, or R4 is a photoactivatable moiety, a fluorescent moiety, or a radioactive moiety, or an optically pure enantiomer of the compound or wherein R1 is H or OH; R2 is H, OH, halogen, unsubstituted or substituted, straight or branched (C1-C5) alkyl group, (C2-C5) alkenyl, or a (C2-C5) alkynyl, (C1-C5) alkoxy, (C2-C5) alkenyloxy, or (C2-C5) alkynyloxy, -N3, -COR5, -CONR5R6, -CO2R5, -OCOR5, -NH(OH), -NR5R6, -NHCOR5, -N(OH)COR5, -CH2OR5, -OCH2CO2R5, -CH2SR5, -CH2NR5R6, -SR5, -OSR5, or -NR5SO2R6, where R5 and R6 are each independently hydrogen, substituted or unsubstituted (C1-C5) alkyl, (C2-C5) alkenyl, or (C2-C5) alkynyl, or a cycloalkyl or aryl group having 3 to 10 carbon atoms; R3 is H or OH; R4 is H, (C1-C10) alkyl, (C1-C10) alkenyl, (C1-C10) alkynyl, -A-Ar, -A-Z-Ar, -SO2-Ar, or -A-NR5, or -R7, where A, Z and Ar are as defined herein, and the use of the compounds for detecting or identifying a receptor which binds the compounds of the invention or for treating a PAF associated condition in a subject.
