Isoquinoline compounds having the formula where R1, R2, Y, m, n, and Z are as defined herein, bind to the minor groove of DNA and have antifungal and antibacterial activity.
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.

The present disclosure encompasses oligonucleotide aptamers selectively binding a target glycosylated polypeptide or protein, and having biased affinity for the glycan through a boronic acid linked to a nucleosidic base of a nucleotide(s). The disclosure further encompasses methods for isolating an aptamer(s) selectively binding a target glycosylated polypeptide, where, from a population of randomized oligonucleotides that have at least one nucleotide having a boronic acid label linked to a base, is selected a first subpopulation of aptamers binding to the target glycosylated polypeptide or protein. This subpopulation is then amplified without using boronic acid-modified TTP, and amplification products not binding to a target glycosylated polypeptide or protein are selected. The second subpopulation of aptamers is then amplified using boronic acid-modified TTP to provide a population of boronic acid-modified aptamers capable of selectively binding to a glycosylation site of a target polypeptide or protein. Other aspects of the disclosure encompass methods for the use of the modified aptamers to detect glycosylated species of a polypeptide or protein.
