Abstract: Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.

Abstract: Compounds having Formula I or II, and methods of making and using thereof, are described herein:

Abstract: The present disclosure encompasses compounds and compositions that are useful as specific AI-2 antagonists for the control of bacterial quorum sensing. Although the AI-2 antagonists according to the present disclosure may not have bactericidal effect, their ability to attenuate virulence, drug resistance, and/or biofilm formation have therapeutic benefits. In addition, the AI-2 antagonists of the present disclosure can also be used as tools to probe bacterial AI-2 functions. The present disclosure also encompasses methods for inhibiting or attenuating microbial virulence, biofilm formation, and drug resistance. The methods are suitable for preventing bacteria from accruing and forming extensive biofilms that may be a health or hygiene hazard or a physical issue, such as in the blockage of water or fuel lines.

Abstract: Boronic acid-modified DNA-based aptamers can be selected to recognize fibrinogen through binding at a glycosylation site and thus are useful for probing the effect of glycosylation pattern changes on the ability for fibrinogen to mediate blood coagulation. In addition, the aptamers of the disclosure also have anticoagulation effects due to their binding to fibrinogen and its cleavage product fibrin. The present disclosure, therefore, encompasses methods for inhibiting fibrin coagulation with an aptamer capable of specifically binding to a glycosylation site of fibrinogen or fibrin. The disclosure further provides oligonucleotide aptamers comprising at least one nucleotide having a boronic acid thereon, where the aptamer is capable of selectively binding to a glycosylation site of fibrinogen, or the derivative thereof.
