3'-Azido-3'-deoxythymidine (AZT) competitively inhibited the transport of thymidine (Km = 0.23 mM) into human erythrocytes with a Ki of 1.0 mM at 37 degrees C. The principal human metabolite of AZT in plasma, the 5'-glucuronide (GAZT), was a weak inh

The membrane permeation characteristics of 5'-deoxythymidine (5'-ddThd) and 5'-azido-5'-deoxythymidine (5'-N3-5'-ddThd) were investigated in human erythrocytes, with an inhibitor-stop assay, at 20 degrees. Uptake of both nucleoside analogs occurred w

The mechanism of transport of the antiviral agent acyclovir (ACV) into human erythrocytes has been investigated. Initial velocities of ACV influx were determined with an "inhibitor-stop" assay that used papaverine to inhibit ACV influx rapidly and co

In the past few years we have been engaged in studying several folate cofactor requiring enzymes derived from human cells; namely thymidylate synthase, dihydrofolate reductase, folyl binder, 10-formyl-H4PteGlu synthetase, 5,10-methenyl-H4PteGlu cyclo

A cloned subline of human cell variants derived from KB cells (KB/6b), 6500-fold resistant to methotrexate (MTX), exhibited a stable 40-fold elevation of the enzyme dihydrofolate reductase (EC 1.5.1.3., DHFR) in the absence of the drug. No difference
