Fibrous Pb(II)‐Based Coordination Polymer Operable as a Photocatalyst and Electrocatalyst for High‐Rate, Selective CO2‐to‐Formate Conversion

Advanced Functional Materials, Volume 35, Issue 28, July 10, 2025.
A coordination polymer [Pb(tadt)]n prepared by a microwave‐assisted solvothermal method selectively reduces CO2 into formate under visible light with a high apparent quantum yield of ≈25% at 400 nm. It can function as a pre‐catalyst, along with conductive Ketjen Black, to form an active PbCO3/Pb3(CO3)2(OH)2 mixture that exhibits a high Faradaic ...

In Vitro and In Silico Evaluation of Isatin‐Derived Spirooxindoles as Antituberculosis Drug Candidates

Chemical Biology &Drug Design, Volume 106, Issue 1, July 2025.
Two compounds, A16 and A17, were active against multidrug‐resistant Mycobacterium tuberculosis isolates (PT‐12 and PT‐20), overcoming key resistance mutations in katG and rpoB, while cytotoxicity assays confirmed that they are non‐toxic. A17 exhibited the highest antituberculosis activity, with molecular docking suggesting enoyl‐[acyl‐carrier‐protein ...

Systematic Review on 1,2,3‐Oxadiazoles, 1,2,4‐Oxadiazoles, and 1,2,5‐Oxadiazoles in the Antimycobacterial Drug Discovery

ChemMedChem, Volume 20, Issue 9, May 5, 2025.
The review focuses on relationships of oxadiazole derivative structures and their antimycobacterial activity including target structures in mycobacteria, in vitro or in vivo pharmacokinetic parameters, and toxicity. Apart from direct antimycobacterial activity, some 1,2,4‐oxadiazole derivatives can potentiate the antimycobacterial effect of ethionamide

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

FEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
