In order to further explore the antiproliferative properties of O-phenoxyethyl and O-adamantyl acylthiocarbamates (ATCs), a series of 14 derivs. was prepd. by a parallel adaptation of a highly convergent one-pot three-step procedure. Ten acylthiocarbamates were selected by the National Cancer Institute drug evaluation program and screened...

In the crystal structure of the novel acylthiocarbamate derivative O-[2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)-ethyl] N-(4-methylphenyl)-N-(3-nitrobenzoyl)thiocarbamate, C25H19N3O6S, intra- and intermolecular pi-pi interactions occur between the phthalimide and N-benzoyl moieties. The partial atomic charges, calculated by ab initio methods,...

Novel classes of cannabinoid 2 receptor (CB2) agonists based on 1,2,3,4-tetrahydropyrrolo[3,4-b]indole and benzimidazole scaffolds have shown high binding affinity toward CB2 receptor and good selectivity over cannabinoid 1 receptor (CB1). A computational study of comparative molecular fields analysis (CoMFA) and comparative molecular...

Novel classes of CB2 agonists based on 4-oxo- 1,4-dihydroquinoline and 4-oxo-1,4-dihydro-1,5-, -1,6- and -1,8-naphthyridine scaffolds have shown high binding affinity toward CB2 receptor and good selectivity over CB1. A computational study of comparative molecular fields analysis (CoMFA) and comparative molecular similarity indices analysis...

Acylthiocarbamates (ATCs) have been identified as a class of potent non-nucleoside HIV-1 reverse transcriptase (RT) inhibitors. A computational strategy based on molecular docking studies followed by comparative molecular fields analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) was used to identify the...

Thiocarbamates (TCs) have been recently identified as a new class of potent non-nucleoside HIV-1 Reverse Transcriptase (RT) inhibitors. A computational strategy based on molecular docking studies, followed by CoMFA and CoMSIA analyses, has been used to elucidate the atomic details of the RT/TC interactions and to identify the most important...

Symmetric formimidoester disulfides (DSs) have recently been identified as a new class of potent nonnucleoside HIV-1 reverse transcriptase (RT) inhibitors. Given that three geometric isomers for DSs are possible, a computational strategy based on molecular docking studies, followed by comparative molecular fields analysis (CoMFA) and...

O-Phthalimidoethyl-N-arylthiocarbamates (TCs) have been recently identified as a new class of potent HIV-1 reverse transcriptase (RT) non-nucleoside inhibitors (NNRTIs), by means of computer-aided drug design techniques. To elucidate the atomic details of RT/TC interaction and validate an earlier TC docking model, the structures of three RT/TC...

To acquire further insight into the structure–activity relationship (SAR) of the thiocarbamates (TCs) described in the preceding work, 57 analogues of the lead compound O-(2-phenylethyl)-N-phenylthiocarbamate I were prepared by parallel solution-phase synthesis. We varied the 2-phenylethyl moiety (mono-substitution on the phenyl ring and...

In order to expand the structure–activity relationship (SAR) studies on Thiocarbamates (TCs), a recently discovered class of potent non-nucleoside HIV-1 reverse transcriptase inhibitors, 38 analogues of the lead O-[2-(2-pyridyl)ethyl]-N-phenylthiocarbamate 1 were prepared by parallel solution-phase synthesis. The SAR strategy was focused on the...

The structural simplification of the non-nucleoside reverse transcriptase inhibitors (NNRTIs) O-(2-phthalimidoethyl)-N-(hetero)aroyl-N-arylthiocarbamates led to design of (hetero)aroyl esters of 2-(N-phthalimido)ethanol as a potential new class of anti-HIV-1 agents. The setup of a soln.-phase parallel synthesis method allowed the rapid prepn....

Fifty-one acylthioureas (ATUs) incorporating imidazolidine-2-thione or its upper cyclohomologue were prepared by parallel synthesis and evaluated against a high number of human cancer cell lines for antiproliferative activity. ATUs 1o (3,5-dichlorobenzoyl), 1s (2-furoyl), 3s (2-furoyl) and 1t (2-thenoyl) displayed activity against leukemia,...

A facile stereoselective synthesis of Knoevenagel-type compds. I (e.g., X = O, S, Y = CN, COMe, CO2Me, COPh, Z = CN, CO2Me, PO(OEt)2, CONH2, COMe, CO2Et, SO2Ph) was accomplished through a 1-pot two-step procedure. The reaction of ethylenethiourea (2-imidazolidinethione, 1) and ethyleneurea (2-imidazolidone, 2) with benzoyl chloride-DMF complex...

A series of 6-amino-4-oxo-1,3-diphenyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl derivatives was synthesized. The compounds demonstrated to be novel, potent and selective inhibitors of Interleukin-8-induced human neutrophil chemotaxis. A SAR study was performed by varying the carbonyl function at position 5 and the chain linked to the...

The mol. duplication of non-nucleoside reverse transcriptase inhibitor (NNRTI) O-(2-phthalimidoethyl)-N-arylthiocarbamates (C-TCs) led to the identification of sym. formimidoester disulfides (DSs) as a novel class of potent NNRTIs.
