N′-[2-(2-thiophene)ethyl]-N′-[2-(5-bromopyridyl)] thiourea as a potent inhibitor of nni-resistant and multidrug-resistant human immunodeficiency virus-1
摘要:
The thiophene-ethyl thiourea (TET) compound N'-[2-(2-thiophene)ethyl]-N'-[2-(5-bromopyridl)]-thiourea (compound HI-443) was five times more potent than trovirdine, 1250 times more potent than nevirapine, 100 times more potent than delavirdine, 75 times more potent than MKC-442, and 50 times more potent than AZT against the multidrug resistant HIV-1 strain RT-MDR with a V106A mutation. HI-443 was almost as potent against the NNI-resistant HIV-I strain A17 with a Y181C mutation as it was against HTLVIIIB. The activity of HI-443 against A17 was ten times more potent than that of trovirdine, 2083 times more potent than that of nevirapine, and 1042 times more potent than that of delavirdine. HI-443 inhibited the replication of the NNI-resistant HIV-1 strain A17 variant with Y181C plus K103N mutations in RT with an IC, value of 3.3 mu M, whereas the IC50 values of trovirdine, nevirapine, and delavirdine were all >100 mu M. These findings establish the novel thiophene containing thiourea compound HI-443 as a novel NNI with potent antiviral activity against NNI-sensitive, NNI-resistant and multidrug-resistant strains of HIV-l.

of potent specific HIV-1 inhibitory compounds is described. The lead compound in the series, N-(2-phenethyl)-N'-(2-thiazolyl)thiourea (1), inhibitsHIV-1 RT using rCdG as the template with an IC50 of 0.9 microM. In MT-4 cells, compound 1 inhibitsHIV-1 with an ED50 of 1.3 microM. The 50% cytotoxic dose in cell culture is > 380 microM. The chemical structure-activityrelationship (SAR) was developed

Phenylethylthiazolylthiourea (PETT) derivatives have been identified as a new series of non-nucleoside inhibitors of HIV-1 RT. Structure-activityrelationshipstudies of this class of compounds resulted in the identification of N-[2-(2-pyridyl)ethyl]-N'-[2-(5-bromopyridyl)]-thiourea hydrochloride (trovirdine; LY300046.HCl) as a highly potent anti-HIV-1 agent. Trovirdine is currently in phase one clinical

Abstract Heterocyclicthioureas having multiple substitutions were prepared in two steps with overall yields of 60–80%. Condensation of a substituted heterocyclic amine with thiocarbonyldiimidazole, followed by treatment with a disubstituted phenylethylamine in dimethyl formamide (DMF), yielded the desired heterocyclicthioureas as crystalline solids.

Abstract Synthesis of β‐fluorophenethylamines was accomplished in three steps with an overall yield of 50%. Condensation of β‐fluorophenethylamine hydrochloride with thiocarbonylimidazole derivative derived from halopyridyl amines in dimethylformamide furnished the desired thiourea compounds as crystalline solids. Several of the β‐fluorophenethyl thiourea compounds inhibited HIV‐1 reverse transcriptase
