Minisci C-H alkylation of N-heteroarenes with aliphatic alcohols: Via beta-scission of alkoxy radical intermediates

A Minisci-type C-H alkylation reaction of N-heteroarenes with aliphatic alcohols via beta-scission of alkoxy radical intermediates under photoredox-catalyzed conditions was developed. The use of the benziodoxole acetate (BI-OAc) oxidant is critical to achieving high efficiency under mild conditions using a slight excess of an alcohol reactant. Primary, secondary, and tertiary alcohols all are compatible. Reactions of various complex N-heteroarenes including drug molecules and steroid natural products have been demonstrated.

Synthesis and antiproliferative activity of indolizinophthalazine-5,12- dione derivatives, DNA topoisomerase IB inhibitors

A series of novel indolizinophthalazine-5,12-dione derivatives were designed and synthesized by the reaction of 6,7-dichlorophthalazine-5,8-dione with active methylene reagents (AMR) and pyridine derivatives. Some of synthesized compounds exhibited significant in vitro antiproliferative activity at micromolar level toward four human tumor cell lines, including lung adenocarcinoma cell, large-cell lung carcinoma cell, breast carcinoma cell and ardriamycin-resistance breast carcinoma cell. The DNA topoisomerase IB inhibitory assay indicated that DNA topoisomerase IB might be a biological target of the synthesized compounds. A series of novel indolizinophthalazine-5, 12-dione derivatives were synthesized. Their in vitro antiproliferative activity toward four human tumor cell lines and DNA topoisomerase IB inhibitory activity was investigated.

Virtual screening identification of nonfolate compounds, including a CNS drug, as antiparasitic agents inhibiting pteridine reductase

Folate analogue inhibitors of Leishmania major pteridine reductase (PTR1) are potential antiparasitic drug candidates for combined therapy with dihydrofolate reductase (DHFR) inhibitors. To identify new molecules with specificity for PTR1, we carried out a virtual screening of the Available Chemicals Directory (ACD) database to select compounds that could interact with L. major PTR1 but not with human DHFR. Through two rounds of drug discovery, we successfully identified eighteen drug-like molecules with low micromolar affinities and high in vitro specificity profiles. Their efficacy against Leishmania species was studied in cultured cells of the promastigote stage, using the compounds both alone and in combination with 1 (pyrimethamine; 5-(4-chlorophenyl)-6-ethylpyrimidine-2,4-diamine). Six compounds showed efficacy only in combination. In toxicity tests against human fibroblasts, several compounds showed low toxicity. One compound, 5c (riluzole; 6-(trifluoromethoxy)- 1,3-benzothiazol-2-ylamine), a known drug approved for CNS pathologies, was active in combination and is suitable for early preclinical evaluation of its potential for label extension as a PTR1 inhibitor and antiparasitic drug candidate.

Perspective on the Hyperpolarisation Technique Signal Amplification by Reversible Exchange (SABRE) in NMR Spectroscopy and MR Imaging

Signal amplification by reversible exchange (SABRE) is a para-hydrogen-based technique that utilises a metal complex, normally centred on iridium, to propagate polarisation from para-hydrogen-derived hydride ligands to spin-? nuclei located in a bound substrate. To date, substrates possessing 1H, 13C, 15N, 19F, 31P, 29Si, and 119Sn nuclei have been polarised by this technique. The exact positioning of these nuclei has a direct bearing on the enhancement observed and so substrates must be chosen or synthesised with care in order to maximise polarisation transfer, and hence the resulting enhancement. The chemical composition of the metal complex must be similarly appraised, as the exchange rate of substrates and para-hydrogen is implicated heavily in efficient polarisation transfer. The nature of the polarisation transfer, whether homogenous or heterogeneous, is another important facet to consider here, as is conducting SABRE in water-based systems. This review discusses the physical and theoretical aspects of the SABRE experiment, as well as the applications of the SABRE technique, namely, the detection of analytes at concentrations far below what would be possible with conventional NMR techniques and the collection of hyperpolarised magnetic resonance images. Advances relating to utilising singlet states for SABRE, pulse sequence design and the nature of the polarisation transfer mechanism are also discussed, and the implications for future SABRE-based discoveries highlighted.
