A series of β‐carboline amides has been synthesized in one‐pot reaction via coupling between an acid and an amine in the presence of HBTU/Et3N. This mild amidation reaction undergoes efficiently and chemoselectively. Bioactivity studies indicate that the β‐carboline amide derivatives exhibit neuroprotective activity and might be developed to be lead compounds for anti‐stroke agents. [ABSTRACT FROM AUTHOR]

Comments on the case of a 37-year-old male who presented with work-related dermatitis. Improvement of the dermatitis after application of corticosteroid creams; Detection of dermal lymphocytic and eosinophilic perivascular infiltration; Immediate immunological immunoglobulin E-mediated mechanism.

The article presents the case study of middle aged woman who was taken to the medical care center with hand dermatitis.
