St. Jan et al., AZT-5 '-(p-bromophenyl methoxyalaninyl phosphate) as a potent and non-toxic anti-human immunodeficiency virus agent, ANTIVIR CHE, 10(1), 1999, pp. 47-52
The potency and selectivity index of the AZT-phenyl phosphate derivatives i
n thymidine kinase (TK)-deficient T cells were substantially enhanced by in
troducing a single para-bromo substituent in the phenyl moiety. AZT-5'-(p-b
romophenyl methoxyalaninyl phosphate) was 43-fold more potent than AZT-5'-(
phenyl methoxyalaninyl phosphate) and was fivefold more potent than AZT in
inhibiting human immunodeficiency virus (HIV) replication in TK-deficient C
EM cells.
