2',3'-didehydro-2',3'-dideoxythymidine (D4T) is a thymidine analogue with potent anti-HIV activity in vitro and is currently being investigated therapeutically in patients with advanced HIV infection. We describe a first one-step competitive ELISA method developed for D4T measurement. Anti-D4T rabbit antibodies were raised against a D4T hemisuccinate-bovine serum albumin immunogen. A D4T-hemisuccinate-horseradish peroxidase conjugate and a monoclonal anti-rabbit IgG antibody insolubilized onto a microtiter plate were used as a tracer and capture system, respectively. The method was capable of detecting 2 ng/ml of D4T in cell cultures and 20 ng/ml of D4T in plasma samples previously separated in microconcentrator devices. Cross-reactivity analysis showed that thymidine, D4T monophosphate, or azidothymidine, were weakly recognized by the ELISA and that thymine or other nucleosides were unreactive. The test was successfully used for the quantification of D4T in cell extracts from CEM or Molt 4 cell lines cultured with D4T and in the plasma of patients with advanced HIV infection, receiving D4T therapy. Moreover this ELISA could be used for the indirect quantification of D4T phosphorylated intracellular metabolites previously separated by reverse phase HPLC and hydrolyzed with alkaline phosphatase.
