Synthesis and anti-HIV activity of 1,1,3-trioxo-2H,4H-thieno[3,4-e][1,2,4]thiadiazines (TTDs): a new family of HIV-1 specific non-nucleoside reverse transcriptase inhibitors.

PMID: 10658585 1999 Bioorganic & medicinal chemistry

Abstract: Some of the test compounds exhibited antiviral activity against L100I RT mutant virus, but significantly lost antiviral activity against K103N, V106A, E138K, Y181C and Y188H RT mutant viruses.

Sensitivity and resistance to (+)-calanolide A of wild-type and mutated forms of HIV-1 reverse transcriptase.

PMID: 10723499 1999 Antiviral therapy

Abstract: We found that RT containing either the V106A or Y181C substitutions, associated with NNRTI resistance, displayed approximately 90-fold resistance to nevirapine but remained fully sensitive to (+)-calanolide A and that the Y181C mutation marginally enhanced susceptibility to the latter drug.

A novel mutation (F227L) arises in the reverse transcriptase of human immunodeficiency virus type 1 on dose-escalating treatment of HIV type 1-infected cell cultures with the nonnucleoside reverse transcriptase inhibitor thiocarboxanilide UC-781.

PMID: 9491916 1998 AIDS research and human retroviruses

Abstract: On increasing drug concentrations (stepwise up to 30 microg/ml) the virus retained the V106A RT mutation but acquired the novel F227L mutation in the RT genome in addition to the L100I, K1O1I, and Y181C mutations.

Abstract: Treatment of wild-type human immunodeficiency virus [HIV-1(IIIB)]-infected cell cultures with the thiocarboxanilide UC-781 under low selective pressure (i.e., 0.01 microg/ml) resulted in the emergence of V106A RT mutant virus.

1,1,3-Trioxo-2H,4H-thieno[3,4-e][1,2,4]thiadiazine (TTD) derivatives: a new class of nonnucleoside human immunodeficiency virus type 1 (HIV-1) reverse transcriptase inhibitors with anti-HIV-1 activity.

PMID: 9517942 1998 Antimicrobial agents and chemotherapy

Abstract: HIV-1 strains containing the L100I, K103N, V106A, E138K, Y181C, or Y188H mutations in their reverse transcriptase (RT) displayed reduced sensitivity to the compounds.

A proline-to-histidine substitution at position 225 of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) sensitizes HIV-1 RT to BHAP U-90152.

PMID: 9634074 1998 The Journal of general virology

Abstract: Construction of both recombinant viruses and recombinant RTs containing the V106A, P225H and V106A+P225H mutations revealed that P225H was indeed responsible for the marked potentiation of the antiviral activity of BHAP against the P225H single-mutant virus and the V106A+P225H double-mutant virus when compared to wild-type and V106A single-mutant viruses, respectively.

Abstract: Surprisingly, the addition of the P225H mutation to the V106A RT mutant genetic background resensitized the V106A

Novel nonnucleoside inhibitors of HIV-1 reverse transcriptase. 8. 8-Aryloxymethyl- and 8-arylthiomethyldipyridodiazepinones.

PMID: 9685236 1998 Journal of medicinal chemistry

Abstract: The most potent compounds were further evaluated against a panel of clinically significant mutant RT enzymes (K103N, V106A, G190A, P236L) and in cytotoxicity and in vitro metabolism assays.

Characteristics of the Pro225His mutation in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase that appears under selective pressure of dose-escalating quinoxaline treatment of HIV-1.

PMID: 9343170 1997 Journal of virology

Abstract: A novel mutation, Pro225His, consistently appeared in a Val106Ala RT-mutated genetic background.

Abstract: The contribution of this mutation to the resistance of the mutant HIV-1 RT to NNRTIs was additive to the resistance caused by the Val106Ala mutation.

Resistance to nevirapine of HIV-1 reverse transcriptase mutants: loss of stabilizing interactions and thermodynamic or steric barriers are induced by different single amino acid substitutions.

PMID: 9405155 1997 Journal of molecular biology

Abstract: Determination of the rate constants for Nevirapine binding (kon) and dissociation (koff) for the mutant and wild-type enzymes showed that mutations L100I and V106A increased the koff values by 12 and 8.5-fold, respectively, without significantly affecting the kon, whereas mutation K103N decreased the kon 5-fold without increasing the koff.

Abstract: The kinetic parameters governing the inhibition by Nevirapine of the RNA-dependent DNA synthesis catalyzed by HIV-1 reverse transcriptase have been determined by steady-state kinetic analysis with the wild-type enzyme and with mutant reverse transcripta

Abstract: less sensitive) Y188L < V106A < L100I < K103N < wild-type.

Highly favorable antiviral activity and resistance profile of the novel thiocarboxanilide pentenyloxy ether derivatives UC-781 and UC-82 as inhibitors of human immunodeficiency virus type 1 replication.

PMID: 8700148 1996 Molecular pharmacology

Abstract: They were also highly efficient (EC50 < or = 0.02 microgram/ml) in suppressing the replication of mutant virus strains that contained mutations in their reverse transcriptase that conferred resistance to other non-nucleoside reverse transcriptase inhibitors (i.e., Tyr181 to Cys, Lys103 to Asn, Val106 to Ala, and Leu100 to Ile).

Differential activities of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine derivatives against different human immunodeficiency virus type 1 mutant strains.

PMID: 7540384 1995 Antimicrobial agents and chemotherapy

Abstract: A series of 23 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine derivatives that were highly potent inhibitors of wild-type human immunodeficiency virus type 1 strain IIIB (HIV-1/IIIB) replication in CEM cells were evaluated against a panel of HIV-1 mutant strains containing the replacement of leucine by isoleucine at position 100 (100-Leu-->Ile), 103-Lys-->Asn, 106-Val-->Ala, 138-Glu-->Lys, 181-Tyr-->Cys, 181-Tyr-->Ile, or 188-Tyr-->His in their reverse transcriptase (RT).
