And the article was included in Journal of Medicinal Chemistry in 2017.Safety of Isoquinolin-7-amine This article mentions the following:

Nicotinamide N-methyltransferase (NNMT) is a fundamental cytosolic biotransforming enzyme that catalyzes the N-methylation of endogenous and exogenous xenobiotics. We have identified small mol. inhibitors of NNMT with >1000-fold range of activity and developed comprehensive structure-activity relationships (SARs) for NNMT inhibitors. Screening of N-methylated quinolinium, isoquinolinium, pyrididium, and benzimidazolium/benzothiazolium analogs resulted in the identification of quinoliniums as a promising scaffold with very low micromolar (IC₅₀ âˆ?1 μM) NNMT inhibition. Computer-based docking of inhibitors to the NNMT substrate (nicotinamide)-binding site produced a robust correlation between ligand-enzyme interaction docking scores and exptl. calculated IC₅₀ values. Predicted binding orientation of the quinolinium analogs revealed selective binding to the NNMT substrate-binding site residues and essential chem. features driving protein-ligand intermol. interactions and NNMT inhibition. The development of this new series of small mol. NNMT inhibitors direct the future design of lead drug-like inhibitors to treat several metabolic and chronic disease conditions characterized by abnormal NNMT activity. In the experiment, the researchers used many compounds, for example, Isoquinolin-7-amine (cas: 23707-37-1Safety of Isoquinolin-7-amine).

In order to discover a novel type of analgesic, dual activity ligands with TRPV1 antagonism and mu-opioid receptor affinity were investigated with the goal of eliciting synergistic analgesia while avoiding the side effects associated with single targeting. Based on a combination approach, a series of 4-benzyl-4-(dimethylamino)piperidinyl analogs I (R = 2,3-dihydrobenzofuran-6-yl, isoquinolin-8-yl, quinolin-5-yl, etc., R¹ = NH, HCCH₃) were designed, synthesized and evaluated for their receptor activities. Among them, compound I (R = quinolin-5-yl) exhibited the most promising dual-acting activity toward TRPV1 and the mu-opioid receptor in vitro. In vivo, compound I (R = quinolin-5-yl) displayed potent, dose-dependent antinociceptive activity in both the 1^st and 2^nd phases in the formalin assay. Consistent with its postulated mechanism, it was confirmed that in vivo, as in vitro, compound I (R = quinolin-5-yl) both antagonized TRPV1 and functioned as a mu-opioid agonist. This result indicates that dual-acting TRPV1 antagonist/mu-opioid ligands can be made and represent a new and promising class of analgesic.
