DNA-protein recognition has shown us the importance of DNA shapes in the recognition process. Specific high-affinity targeting of DNA shapes by small molecules is desirable for many biological applications that involve regulation of DNA based processes. Here, the effect of linker length and rigidity on the affinity of a conjugated neomycin dimer for a specific DNA shape (B* form) AT-rich DNA was explored. Binding constants approximating 10(8) M (1) for optimal linker lengths of 18-19 atoms are reported herein. (C) 2015 Elsevier Ltd. All rights reserved.

Ureido and thioureido derivatives of 2-acetamido-2-deoxy-beta-D-glucose, 1-amino-1-deoxy-D-glucitol and 2-(2-aminoethoxy)ethanol were prepared as N-acetyl-beta-D-hexosaminidase (NAHase) inhibitors and were evaluated on Trichomonas vaginalis NAHase. Although none showed complete inhibition of the enzyme at 100 microM, 1-amino-1-deoxy-D-glucitol derivatives acted as competitive inhibitors of the NAHase
