title: Selective axonal transport of anthracycline antibiotics.
abstract: The retrograde intraaxonal transport of several anthracycline antibiotics was assessed in the peripheral nervous system of adult mice. Despite certain chemical similarities, the intraaxonal transport of these molecules was variable and could be correlated with the structure of the aminosugar at the R-2 position. One particularly interesting compound, 4'-deoxydoxorubicin, was transported by dorsal root ganglia axons, but not by the axons of ventral horn neurons. These observations suggest that the sugar component of a molecule may be important for its intraaxonal transport in the peripheral nervous system.
