Comparison of the uptake of vitamin B12 by Spirometra mansonoides and Hymenolepis diminuta and the functional groups of B12 analogs affecting uptake.

Uptake of 57Co-vitamin B12 (CN- Cbl) by spargana (larvae) of the pseudophyllidean tapeworm, Spirometra mansonoides, was affected by temperature, was saturable with respect to concentration of CN- Cbl in the medium, and was inhibited in the presence of several structural analogs of CN- Cbl. In uptake studies with various analogs it was found that chemical modifications which altered the benzimidazole moiety greatly reduced the ability of the worm to take up these analogs. Modifications in which the amide groups of the propionamide side chains were removed, resulting in carboxylic acid derivatives, showed greatly reduced transport properties. The C-13 epimer in which the e-proprionamide side chain is no longer on the benzimidazole side (lower) of the molecule but is inverted to a position on the upper side was freely taken up. The pharmacological implications of this last observation are discussed. Adult Hymenolepis diminuta did not take up CN- Cbl in vitro, which correlated with the finding that no CN- Cbl was detected in the worm by Ochromonas malhamensis assay.[1]
