Curr Org Synth 2020; 17:224-229. [DOI: 10.2174/1570179417666200212111956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 01/17/2020] [Accepted: 01/20/2020] [Indexed: 01/31/2023]
Abstract
:
New substituted 1,4-naphthoquinones have been prepared in good overall yields through the
naphthol route. The cytotoxicity of these compounds was tested in vitro on MCF-7 breast tumor cells. The
most active compound 14 displayed an IC50 of 15μM.
Objective:
To investigate the cytotoxicity of new naphthoquinones derivatives on MCF-7 cells.
Methods:
Synthesis of new naphtoquinones derivatives and in vitro evaluation of their cytotoxicity on MCF-7
cells (rezasurin cell-based assay).
Results:
Starting from Ethyl 4-hydroxy-6,7-dimethoxy-2-naphthoate, four naphthoquinones were prepared and
exhibited substantial cytotoxicity against MCF-7 cells.
Conclusion:
Preliminary studies of the structure-activity relationship have shown the influence of the structural
parameters and, in particular, the nature of the naphthoquinone side chain.

Abstract
A Brønsted acid enabled nickel-catalyzed hydroalkenylation of aldehydes and styrene derivatives has been developed. The Brønsted acid acts as a proton shuttle to transfer a proton from the alkene to the aldehyde, thereby leading to an economical and byproduct-free coupling. A series of synthetically useful allylic alcohols were obtained through one-step reactions from readily available styrene derivatives and aliphatic aldehydes in up to 88 % yield and with high linear selectivity.

Abstract
A new pseudopeptide epoxide inhibitor, designed for irreversible binding to HIV protease (HIV-PR), has been synthesized and characterized in solution and in the solid state. However, the crystal structure of the complex obtained by inhibitor-enzyme cocrystallization revealed that a minor isomer, with inverted configuration of the epoxide carbons, has been selected by HIV-PR during crystallization. The structural characterization of the well-ordered pseudopeptide, inserted in the catalytic channel with its epoxide group intact, provides deeper insights into inhibitor binding and HIV-PR stereoselectivity, which aids development of future epoxide-based HIV inhibitors.

Abstract
Peptidomimetic inhibitors of HIV-1 PR are still a key resource in the fight against AIDS. Here we describe the synthesis and biological activity of HIV-1 PR inhibitors based on four novel dihydroxyethylene isosteres of the Phe-Pro and Pro-Pro dipeptides. The isosteres, containing four stereogenic centers, were synthesized in high yield and excellent stereoselectivity via the cyclization of epoxy amines derived from α-amino acids. The inhibitors were assembled by coupling the isosteres with suitable flanking groups and were screened against recombinant HIV PR showing activities in the subnanomolar to micromolar range. Two Phe-Pro-based inhibitors active at the nanomolar level were further investigated: both inhibitors combine the ability to suppress HIV-1 replication in infected MT-2 cells with low cytotoxicity against the same cells, thereby displaying a high therapeutic index. These results demonstrate the potential of the new Phe-Pro dihydroxyethylene isostere as a core unit of powerful HIV-1 PR inhibitors.

Abstract
[reaction: see text] The base-catalyzed hydroazidation of alpha'-amino alpha,beta-unsaturated ketones with in situ generated hydrazoic acid was found to proceed with high stereoselectivity in favor of the syn product. The stereoselectivity is controlled by the configuration of the enone and syn/anti ratios up to 7:1 were obtained with secondary and tertiary amines at low temperature. By this route the diamino alcohol core of HIV-PR inhibitors ritonavir and lopinavir was synthesized in 37% yield from phenylalanine.
