AFM32a hydrochloride  (Synonyms: PAD2-IN-1 hydrochloride)

AFM32a (PAD2-IN-1) hydrochloride, a benzimidazole-based derivative, is a potent and selective protein arginine deiminase 2 (PAD2) inhibitor. AFM32a hydrochloride shows superior selectivity for PAD2 over PAD4 (95-fold) and PAD3 (79-fold)^[1].

Protein Arginine Deiminase 2 (PAD2)^[1]

In the target engagement assay, the EC ₅₀ of AFM32a (compound 32a) hydrochloride is 8.3 μM in HEK293T/PAD2 cells, the enhanced potency of AFM32a overcomes its relatively poor ability to enter cells^[1].
AFM32a (compound 32a; 1-25 μM) hydrochloride treatment strongly inhibits histone H3 citrullination with an EC ₅₀ of 2.7 μM in HEK293T/PAD2 cells^[1].
