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.

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.
