An approach to use an unusual adenosine transporter to selectively deliver polyamine analogues to trypanosomes
摘要:
In this paper we describe an approach to selectively deliver compounds to trypanosomes using an adenosine transporter which is unique to the trypanosome. Various polyamine analogues have been attached to known substrates of this adenosine transporter. The compounds prepared interact specifically with the adenosine transporter, some with a similar efficiency to berenil, a known substrate. (C) 1998 Elsevier Science Ltd. All rights reserved.
An efficient five-step synthesis method was developed to obtain tritolylporphyrin and protoporphyrin IX polyamine conjugates. These compounds were composed of either one polyamine unit (spermidine or spermine) covalently tethered to monocarboxyphenyl tritolylporphyrin or two molecules of polyamines borne by protoporphyrin IX In each compound, an aliphatic spacer arm is linked to the N-4 polyamine position. Photocytotoxicity of these new compounds was evaluated against K562 human chronic myelogenous leukemia cells and compared to Photofrin II (R); protoporphyrin IX polyamine conjugates exhibited much stronger photocytocicity than Photofrin II (R) and were shown to readily induce necrosis in treated cells.
