Ultrapotent Inhibitor of Clostridioides difficile Growth, Which Suppresses Recurrence in Vivo

Clostridioides difficile is the leading cause of healthcare-associated infection in the U.S. and considered an urgent threat by the Centers for Disease Control and Prevention (CDC). Only two antibiotics, vancomycin and fidaxomicin, are FDA-approved for the treatment of C. difficile infection (CDI), but these therapies still suffer from high treatment failure and recurrence. Therefore, new chemical entities to treat CDI are needed. Trifluoromethylthio-containing N-(1,3,4-oxadiazol-2-yl)benzamides displayed very potent activities [sub-μg/mL minimum inhibitory concentration (MIC) values] against Gram-positive bacteria. Here, we report remarkable antibacterial activity enhancement via halogen substitutions, which afforded new anti-C. difficile agents with ultrapotent activities [MICs as low as 0.003 μg/mL (0.007 μM)] that surpassed the activity of vancomycin against C. difficile clinical isolates. The most promising compound in the series, HSGN-218, is nontoxic to mammalian colon cells and is gut-restrictive. In addition, HSGN-218 protected mice from CDI recurrence. Not only does this work provide a potential clinical lead for the development of C. difficile therapeutics but also highlights dramatic drug potency enhancement via halogen substitution.

Synthesis and antitubercular activity of 2-(1H-pyrrol-1-Yl)-5- substituted-1,3,4-oxadiazoles

A series of 2-(1H-pyrrol-1-yl)-5-substituted-1,3,4-oxadiazole derivatives were prepared and evaluated for their antitubercular activity. These derivatives were synthesized by the reaction of 5-substituted-1,3,4-oxadiazol-2-amines (4a-j) with 2,5- dimethoxytetrahydrofuran in dried acetic acid. Structures of the newly synthesized compounds were confirmed on the basis of physico-chemical and spectral data. All the synthesized compounds were screened for their antitubercular activity using microplate almar blue assay (MABA) method. Compounds have shown moderate to good antitubercular activity against M. tuberculosis H37Rv microorganism.

Synthesis and in vitro antitumor activity of 1,3,4-oxadiazole derivatives based on benzisoselenazolone

A series of novel 1,3,4-oxadiazole derivatives based on benzisoselenazolone has been prepared and tested for antiproliferative activity in vitro against the cells of human cancer cell lines: SSMC-7721 (human liver cancer cell), MCF-7 (human breast cancer cell) and A549 (human lung cancer cell). All the compounds obtained exhibited antiproliferative activity and showed selective cytotoxicity against different cancer cells. Compounds 7d and 7i showed significant antiproliferative activities against MCF-7 cells, with IC50 values of 1.07 and 1.76/μM respectively. Compound 7d were found to be the most potent compound against SSMC-7721 cells, with IC50 values 4.46/μM.
