  Design, Synthesis and Activity of Ascorbic Acid Prodrugs of Nipecotic, Kynurenic and Diclophenamic Acids, Liable to Increase Neurotropic Activity

  摘要：

  To improve the entry of certain drugs into brain, ascorbic acid (AA) conjugates of these drugs were synthesized and their capacity to interact with SVCT2 ascorbate transporters was explored. Kinetic studies clearly indicate that all of the conjugates were able to competitively inhibit ascorbate transport in human retinal pigment epithelial cells (HRPE). In vivo studies, in a mouse model system, demonstrate that conjugate 3 is better absorbed compared to the nonconjugated parent drug.

  groups from oxyarene N-heterocycles at positions capable for 2-/4-O-pyridine–2-/4-pyridone tautomerism. Blue light irradiation, a [Ru] or [Ir] photocatalyst, and ascorbic acid in a water–acetonitrile solution debenzylates a variety of aryl N-heterocycles cleanly and selectively. Ascorbic acid has two functions in the reaction. On the one hand, it protonates the N-heterocycles that reduces their reduction

  Preliminary investigations allowed us to anticipate that conjugation of nipecotic acid with L-ascorbate (AA) gave a prodrug endowed with anticonvulsant activity in mice. In view of these results, and in order to get deepen insight into the molecular aspects at the base of the transport mechanism, a second generation of compounds, based on 6-bromo-6-deoxy-L-ascorbic acid (BrAA) as the carrier molecule was designed and synthesized. Effects of the chirality of the transported drug was also investigated on R- and S-nipecotic acid. Interaction and uptake modalities were evaluated in our in vitro model based on human retinal pigment epithelium cells (HRPE), which expresses the membrane L-ascorbic acid (AA) SVCT2 transporters. A remarkable increase on SVCT2 affinity was found going from AA to BrAA conjugates, that is, 11 (K-i = 1187 +/- 78 muM) versus 19 (K-i = 193 +/- 14 muM) and 12 (K-i = 39.8 +/- 3.2 muM) versus 20, (K-i = 7.4 +/- 0.8 muM). Taken together, these data are in agreement with our initial hypothesis on the possibility to achieve better affinities by conjugation with AA analogs, and also consent to hypothesize the presence of accessory interactions that may improve transporters recognition.
