Tetraaza[7]–[15]helicenes Synthesized by Two‐Step Strategy: Length‐Controlled Chiral π‐Systems Exhibiting Amplified Circularly Polarized Luminescence

open access: yesAngewandte Chemie, Volume 138, Issue 14, 27 March 2026.
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.

Novel Synthetic Derivatives of Substituted Amino -1, 2, 4-Thiadiazoles

open access: yesInternational Journal of Chemical and Physical Sciences, 2012
A novel series of 3-amino-5-substituted amino-1,2,4-thiadiazoles (5a-f) and 3substituted thiocarbamido-5-substituted amino-1,2,4-thiadiazoles (6a-f) have been obtained by the oxidative cyclization of 1-substituted-3-formamidinothiocarbamide 1 (3af) and 1,3-bis(substitutedthioamido)-guanidine 1 (4a-f) with bromine respectively.

Targeting the Membrane‐Embedded Rhomboid Protease GlpG: A Multimodal Strategy for Inhibitor Discovery and Mechanistic Insight

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Created in BioRender. Bohg, C. (2026) https://BioRender.Com/ vi9hi4f. Rhomboid proteases are a mechanistically unique and evolutionarily conserved protein family. Despite their pharmacological relevance, the development of selective inhibitors has lagged behind that of soluble proteases.
