Synthesis and anti-Pneumocystis carinii pneumonia activity of novel dicationic dibenzothiophenes and orally active prodrugs

Dicationic carbazoles have been found to be highly active against a rat model of Pneumocystis carinii pneumonia (PCP). Unfortunately, amidoxime derivatives, designed as prodrugs, were inactive against PCP even though the corresponding amidines were highly active. In the present work, a series of 2,8- and 3,7-bis cationic dibenzothiophenes was synthesized and assayed for anti-PCP activity. Three of the compounds proved to be more potent and less toxic than a standard anti-PCP drug (pentamidine) when given intravenously. Unlike the carbazoles, a dibenzothiophene amidoxime prodrug given orally reduced the parasite load by more than 99%. While no quantitative correlation was seen between anti-PCP activity and DNA binding, a strong level of DNA binding was found to be necessary for antimicrobial activity.

Double-(S, S - dioxo - dibenzo thiophene) and high output compound and its preparation method and application

The invention discloses a bi(S,S-dioxo-dibenzothiophene) five-membered ring compound and a preparation method and application thereof. The existence of bi-sulfuryl in the bi(S,S-dioxo-dibenzothiophene) five-membered ring compound is more beneficial for improving the electron affinity of molecules. Alkyl chains are introduced on a five-membered ring, so that the solubility of monomers in an organic solvent can be obviously improved. The plane conjugacy of the compound is better, and is beneficial for the transmission of a current carrier. Higher D-A mutual effect existing in the molecules of the compound endows higher fluorescence of the material. The bi(S,S-dioxo-dibenzothiophene) five-membered ring compound is synthesized and obtained through common organic chemistry reactions such as substitution reactions, Suzuki coupling and ring-closure reactions and oxidation reactions. The compound has good solubility in the organic solvent, and is suitable for solution processing. The compound has wide application prospects in the fields of organic luminescence display, organic photovoltaic cells and organic field-effect tubes.

Photophysical properties and optical power limiting ability of Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at different positions

Two series of Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at different positions have been synthesized. In the absorption spectra, the Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 3,6-position have blue-shift with respect to the corresponding analogs bearing fluorene-type ligands with ethynyl units at 2,7-position, showing better transparency in the visible light region. Moreover, the Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 3,6-position show stronger triplet emission than corresponding analogs bearing fluorene-type ligands with ethynyl units at 2,7-position in the photoluminescent (PL) spectra. Furthermore, these Pt(II) polyynes were applied to optical power limiting (OPL) field. The Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 2,7-position show better OPL performance than the corresponding analogs with fluorene-type ligands of ethynyl units at 3,6-position. Therefore, changing the position of the ethynyl units in fluorene-type ligands can not only effectively control the photophysical properties of the Pt(II) polyynes, but also has an important effect on their OPL ability.

Cyclization of 2-Biphenylthiols to Dibenzothiophenes under PdCl2/DMSO Catalysis

A palladium-catalyzed synthesis of dibenzothiophenes from 2-biphenylthiols is described. This highly efficient reaction employs a simple PdCl2/DMSO catalytic system, in which PdCl2 is the sole metal catalyst and DMSO functions as an oxidant and solvent. This transformation has broad substrate scope and operational simplicity and proceeds in high yield. The synthetic utility was demonstrated by the facile synthesis of helical dinapthothiophene 3 and an eminent organic semiconductor DBTDT 4. Importantly, highly strained trithiasumanene 5, a buckybowl of considerable synthetic challenge, was observed under this catalytic system.

Facile preparation of dibenzoheterocycle-functional nanoporous polymeric networks with high gas uptake capacities7

A consolidated ionothermal strategy was developed for the polymerization of thermally unstable nitriles to construct high performance materials with permanent porosity, and carbazole, dibenzofuran, and dibenzothiophene were separately introduced into covalent triazine-based networks to investigate the effects of heterocycles on the gas adsorption performance. Three nitriles, namely 3,6-dicyanocarbazole, 3,6-dicyanodibenzofuran, and 3,6- dicyanodibenzothiophene, were designed and synthesized, which were readily converted to heat-resistant intermediates at a moderate temperature and then polymerized to create highly porous poly(triazine) networks instead of the traditional one-step procedure. This documents an improved strategy for the successful construction of heterocyclic-functional triazine-based materials. The chemical structures of monomers and polymers were confirmed by 1H NMR, FTIR, and elemental analysis. Such polymers with high physical-chemical stability and comparable BET surface areas can uptake 1.44 wt % H2 at 77 K/1 bar and 14.0 wt % CO2 at 273 K/1 bar and present a high selectivity for gas adsorption of CO2 (CO2/N2 ideal selectivity up to 45 at 273K/1.0 bar). The nitrogen- and oxygen-rich characteristics of carbazole and dibenzofuran feature the networks strong affinity for CO2 and thereby high CO2 adsorption capacity. This also helps to thoroughly understand the influence of pore structure and chemical composition on the adsorption properties of small gas molecules.

Optical activity of heteroaromatic conjugated polymer films prepared by asymmetric electrochemical polymerization in cholesteric liquid crystals: Structural function for chiral induction

We electrochemically polymerized various achiral heteroaromatic monomers in left-handed helical cholesteric liquid crystal (CLC) media. Circular dichroism (CD) spectroscopy revealed that most of the resulting conjugated polymer films exhibited both the first negative and second positive Cotton effects near their absorption maxima. This indicates left-handed helical aggregation of the conjugated main chains, which is consistent with left-handed helical order of the CLC. This result suggests that the left-handed helical CLC environment induced left-handed helical aggregation of the polymers during the electrodeposition. However, CD intensity of the polymers depends on the structure of the parent monomers. Systematic investigation of the relationship between monomer structures and optical activity of the polymers indicates that linearity of the conjugated main chains and excluded volume interaction between the monomers and the CLC are important factors for producing optical activity of the polymers.
