Pest Management Science, EarlyView.The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

Acta Zoologica, EarlyView.ABSTRACT Halyomorpha halys (Stål, 1855) is an invasive pentatomid species causing considerable economic losses in agricultural systems. Despite the ecological importance of the metathoracic scent gland (MTG) in chemical defence and communication, detailed information on its morphology and secretion composition remains limited. In the present study, the

ChemMedChem, Volume 21, Issue 17, 14 September 2026.Among 30 synthesized pyrrolo[1,2‐a]pyrazine analogs, compounds B1 and B3 showed strong and selective cytotoxicity toward TNBC cells, inducing apoptosis through Akt suppression and JNK activation. Triple‐negative breast cancer (TNBC) remains a major clinical challenge due to the absence of effective targeted therapies.
