emission color of the quinoxaline based chromophores can be conveniently accomplished by the remote substituent group. The determined absorption and emission maximum as well as the Stokes shifts strongly correlate with Hammett σp+ parameters. Besides, photophysical properties of selected derivatives in the solid state, biphasic solutions, and PMMA films, along with their relationships, are comparatively

Emergence of MDR‐TB and XDR‐TB led to the failure of available anti‐tubercular drugs. In order to explore, identify and develop new anti‐tubercular drugs, novelpeptidomimetic series of Mtb–peptide deformylase (PDF) inhibitors was designed and synthesized. In vitro antimycobacterial potential of compounds was established by screening of compounds against Mycobacterium tuberculosis H37Rv strain using

Unnatural amino acids (UAAs) are key building blocks with widespread application across several scientific fields. Therefore, it is highly attractive to develop straightforward and simple methodologies capable of granting quick access to these species. Herein we report a light‐mediated protocol for the synthesis of UAA via radical decarboxylative processes. This methodology, which employs readily available
