A series of new DNA binding molecules NCD-Cn-SH (n = 3, 4, 5, and 6) is reported, which possesses the NCD (naphthyridine carbamate dimer) domain selectively binding to the G-G mismatch in the 5′-CGG-3′/5′-CGG-3′ sequence and a thiol moiety, which undergoes spontaneous dimerization to (NCD-Cn-S)2 upon oxidation under aerobic conditions. The S-S dimer (NCD-Cn-S)2 produced the 1:1 binding complex with improved thermal stability. The dimer binding to the CGG/CGG DNA showed higher positive cooperativity than the binding of monomer and previously synthesized NCTn derivative. The dimerization of NCD-Cn-SH was selectively accelerated on the CGG repeat DNA but not on the CAG repeat DNA.

(+)-Methamphetamine (METH) use and addiction has grown at alarming rates over the past two decades, while no approved pharmacotherapy exists for its treatment. Immunopharmacotherapy has the potential to offer relief through producing highly specific antibodies that prevent drug penetration across the blood-brain barrier thus decreasing reinforcement of the behavior. Current immunotherapy efforts against methamphetamine have focused on a single hapten structure, namely linker attachment at the aromatic ring of the METH molecule. Hapten design is largely responsible for immune recognition, as it affects presentation of the target antigen and thus the quality of the response. In the current paper we report the systematic generation of a series of haptens designed to target the most stable conformations of methamphetamine as determined by molecular modeling. On the basis of our previous studies with nicotine, we show that introduction of strategic molecular constraint is able to maximize immune recognition of the target structure as evidenced by higher antibody affinity. Vaccination of GIX+ mice with six unique METH immunoconjugates resulted in high antibody titers for three particularly promising formulations (45-108 μg/mL, after the second immunization) and high affinity (82, 130, and 169 nM for MH2, MH6, and MH7 hapten-based vaccines, respectively). These findings represent a unique approach to the design of new vaccines against methamphetamine abuse.
