Skeletal Rearrangement of Twisted Thia-Norhexaphyrin: Multiply Annulated Polypyrrolic Aromatic Macrocycles

A hybrid thia-norhexaphyrin comprising a directly linked N-confused pyrrole and thiophene unit (1) revealed unique macrocycle transformations to afford multiply inner-annulated aromatic macrocycles. Oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone triggered a cleavage of the C-S bond of the thiophene unit, accompanied with skeletal rearrangement to afford unique pi-conjugated products: a thiopyrrolo-pentaphyrin embedded with a pyrrolo[1,2]isothiazole (2), a sulfur-free pentaphyrin incorporating an indolizine moiety (3), and a thiopyranyltriphyrinoid containing a 2H-thiopyran unit (4). Furthermore, 2 underwent desulfurization reactions to afford a fused pentaphyrin containing a pyrrolizine moiety (5) under mild conditions. Using expanded porphyrin scaffolds, oxidative thiophene cleavage and desulfurization of the hitherto unknown N-confused core-modified macrocycles would be a practical approach for developing unique polypyrrolic aromatic macrocycles.

NAD(P)H Quinone Oxidoreductase 1 (NQO1)-Bioactivated Pronqodine A Regulates Prostaglandin Release from Human Synovial Sarcoma Cells

Natural products have contributed to the elucidation of biological mechanisms as well as drug discovery research. Even now, the expectation for natural products is undiminished. We screened prostaglandin release inhibitors that had no effect on in vitro cyclooxygenase activity derived from natural product sources and discovered pronqodine A. Using spectral analysis and total synthesis, the structure of pronqodine A was shown to be a benzo[d]isothiazole-4,7-dione analogue. Evaluation of the biological activity of pronqodine A revealed that the NAD(P)H dehydrogenase quinone 1 (NQO1) converted pronqodine A into a two-electron reductive form. The reductive form underwent autoxidation and reversed to its native form immediately with the generation of reactive oxygen species. Further investigations proved that pronqodine A inhibited cyclooxygenase enzyme activity only in the presence of NQO1. Pronqodine A acts as a potential bioreductive compound, inhibiting prostaglandin release in selectively activated NQO1-expressing cells.

Synthesis, antiproliferative and antiviral activity of imidazo[4,5-d]isothiazole nucleosides as 5:5 fused analogs of nebularine and 6-methylpurine ribonucleoside

A series of imidazo[4,5-d]isothiazole nucleosides related to the antibiotic nebularine and the highly cytotoxic 6-methyl-9-beta-D-ribofuranosylpurine have been synthesized from the corresponding heterocycles. The sodium salt glycosylation of the imidazo[4,5-d]isothiazoles proceeded smoothly, giving mixtures of N-4 and N-6 regioisomers in generally good yields. The protected derivatives were deblocked using standard conditions to afford the desired imidazo[4,5-d]isothiazole nucleosides, usually as crystalline solids. None of the new nucleosides or heterocycles displayed selective activity against human cytomegalovirus (HCMV) or herpes simplex virus type 1 (HSV-1). The N-6 glycosylated imidazo[4,5-d]isothiazoles were completely inactive up to the highest concentration tested. The N-6 glycosylated imidazo[4,5-d]isothiazoles also were inactive in antiproliferative and cytotoxicity assays, except for 3-methyl-6-beta-D-ribofuranosylimidazo[4,5-d]isothiazole (15a) and 5-(benzylthio)-6-(2-deoxy-beta-D-ribofuranosyl)imidazo[4,5-d]isothiazole (5e), which showed moderate inhibition of L1210 cell growth. However, the heterocycles and several of the N-4 glycosylated derivatives were toxic to HFF, KB and L1210 cells; compounds with 5-benzylthio substituents were the most cytotoxic agents in this series.

Transition Metal-Free Synthesis of Substituted Isothiazoles via Three-Component Annulation of Alkynones, Xanthate and NH4I

A protocol was described to access diverse isothiazoles with functionalization potential via transition metal-free three-component annulation of alkynones, potassium ethylxanthate (EtOCS2K) and ammonium iodide (NH4I). A sequential regioselective hydroamination/thiocarbonylation/intramolecular cyclization cascade achieved the efficient formation of consecutive C-N, C-S and N-S bonds in a one-pot process.

Ternary blend polymer solar cells with enhanced power conversion efficiency

The use ternary organic components is currently being pursued to enhance the power conversion efficiency of bulk heterojunction solar cells by expanding the spectral range of light absorption. Here, we report a ternary blend polymer solar cell containing two donor polymers, poly-3-oxothieno[3,4-d]isothiazole-1,1-dioxide/benzodithiophene (PID2), polythieno[3,4-b]-thiophene/benzodithiophene (PTB7) and [6,6]-phenyl C71 butyric acid methyl ester (PC71BM) as an acceptor. The resulting ternary solar cell delivered a power conversion efficiency of 822% with a short-circuit current density J(sc) of 16.8 mA cm(-2), an open-circuit voltage V-oc of 0.72 V and a fill factor of 68.7%. In addition to extended light absorption, we show that J(sc) is improved through improved charge separation and transport and decreased charge recombination, resulting from the cascade energy levels and optimized device morphology of the ternary system. This work indicates that ternary blend solar cells have the potential to surpass high-performance binary polymer solar cells after further device engineering and optimization.

Fused Isothiazole S-Oxide Systems from Cycloaddition Reactions of N-Benzylisothiazol-3-amine 1-Oxide

The racemic N-benzylisothiazol-3-amine 1-oxide (2) was demonstrated to be an efficient partner in Diels – Alder reactions (Schemes 2-4) and a good dipolarophile in 1,3-dipolar cycloaddition reactions with nitrile oxides (Scheme 5). Polycyclic isothiazole S-oxides with different substitution patterns were obtained from 2 in good yield and in a fully regioselective way. Improved diastereoselection was observed preforming the Diels – Alder or 1,3-dipolar cycloaddition reactions in H2O.

Synthesis and diabetic neuropathic pain-alleviating effects of 2N-(pyrazol-3-yl)methylbenzo[d]isothiazole-1,1-dioxide derivatives

A novel series of fused-benzensulfonamide 2-N-(pyrazol-3-yl)methylbenzoldlisothiazole-1,1-dioxide derivatives was designed and synthesized as metabolically stable T-type calcium channel inhibitors. Several compounds, 9, 10, and 17, displayed potent T-type channel inhibitory activity. Among them, compounds 10 and 17 showed good metabolic stability in human liver microsomes, and low hERG channel and CYP450 inhibition. Compound 10 exhibited diabetic neuropathic pain-alleviating effects in a streptozotocin-induced peripheral diabetic neuropathy (PDN) model. The maximum efficacy of compound 10, which was 3-fold more potent than gabapentin, was observed at 1 h after administration, and co administration of compound 10 with gabapentin showed a considerable synergic effect.
