The P236L Delavirdine-Resistant Human Immunodeficiency Virus Type 1 Mutant Is Replication Defective and Demonstrates Alterations in both RNA 5′-End- and DNA 3′-End-Directed RNase H Activities

Abstract excerpt

The nonnucleoside reverse transcriptase (RT) inhibitor (NNRTI) delavirdine (DLV) selects in vitro for the human immunodeficiency virus type 1 (HIV-1) RT mutation P236L, which confers high-level resistance to DLV but not other NNRTIs. Unexpectedly, P236L has developed infrequently in HIV-1 isolates obtained from patients receiving DLV; K103N is the predominant resistance mutation observed in that setting. We...
