Dibucaine is a local anesthetic of the amide type now generally used for surface anesthesia.Target: Sodium ChannelDibucaine is an amide local anesthetic. Dibucaine reduced the degradation of BSA-gold complex in the reservosomes, which was not caused either by an inhibition of the whole proteolytic activity of the parasite or by a reduction on the expression levels of cruzipain [1].Dibucaine, a quaternary ammonium compound, inhibited SChE to a minimum within 2 min in a reversible manner. The inhibition was very potent. It had an IC(50) of 5.3 microM with BuTch or 3.8 microM with AcTch. The inhibition was competitive with respect to BuTch with a K(i) of 1.3 microM and a linear-mixed type (competitive/noncompetitive) with respect to AcTch with inhibition constants, K(i) and K(I) of 0.66 and 2.5 microM, respectively.

Ranolazine is an antianginal medication.Target: Sodium ChannelRanolazine is believed to have its effects via altering the transcellular late sodium current. It affects the sodium-dependent calcium channels during myocardial ischemia in rabbits by altering the intracellular sodium level [1].
