α-Conotoxin Im-I is a selective α7/α9 nAChR antagonist, blocking α7 nicotinic receptors with the highest apparent affinity, while having an 8-fold lower affinity for homomeric α9 nicotinic receptors. α-Conotoxin Im-I is toxic and induces seizures in rodents. α-Conotoxin Im-I is a tool for studying neuronal nAChR.

2-Amino-6-(methylsulfonyl)benzothiazole is identified as a new development of improved pteridine reductase-1 (PTR1) inhibitors and anti-trypanosomatidic agents.

NS-2028 is a highly selective soluble Guanylyl Cyclase (sGC) inhibitor (IC50: 30 nM and 200 nM for basal and NO-stimulated enzyme activity).
