- Design, synthesis, and biological evaluation of 5-aminotetrahydroquinoline-based LSD1 inhibitors acting on Asp375
-
The abnormal expression of lysine-specific histone demethylase 1 (LSD1) is associated with different cancer types, and LSD1?inhibitory activity seems to have high therapeutic potential in cancer treatment. Here, we report the design, synthesis, and biochemical evaluation of novel 5-aminotetrahydroquinoline-based LSD1 inhibitors. Among them, compounds A6, A8, B1–B5, and C4 showed preferable inhibitory effects on LSD1, with IC50 = 0.19–0.82 μM. Several potent compounds were selected to evaluate their antiproliferative activity on A549 cells and MCF-7 cells with a high expression of LSD1. The potential binding modes of the compounds were revealed through molecular docking to rationalize the potency of compounds toward LSD1. Our data recognized that the 5-aminotetrahydroquinoline scaffold may serve as a starting point for developing potent LSD1 inhibitors for cancer therapy.

- Design, synthesis and biological evaluation of tetrahydroquinoline-based reversible LSD1 inhibitors
-
The targeted regulation of LSD1, which is highly expressed in a variety of tumor cells, is a promising cancer therapy strategy. Several LSD1 inhibitors are currently under clinical evaluation, and most of these inhibitors are irreversible. Here, we report the design, synthesis and biochemical evaluation of novel tetrahydroquinoline-based reversible LSD1 inhibitors. Compounds 18s and 18x, which are selective to LSD1 over MAO-A/B, exhibit excellent LSD1 inhibition at the molecular levels with IC50 = 55 nM and 540 nM, respectively. The classic Lineweaver–Burk plots revealed that compound 18s could reversibly bind the LSD1 enzyme in a noncompetitive manner. Molecular docking was used to reveal the potential binding-mode of the compounds and interpret the structure-activity relationships. Furthermore, compounds 18s and 18x significantly inhibited proliferation (IC50 = 1.13 μM and 1.15 μM, respectively) and induced apoptosis in MGC-803 cells with high expression of LSD1. Compound 18x showed acceptable liver microsomal stability. Meanwhile, 18x did not appear to inhibit CYPs at 10 μM in vitro. Remarkably, the oral administration of compound 18x can inhibit the growth of MGC-803 xenograft tumors without significant side effects. Our findings suggest that tetrahydroquinoline-based LSD1 inhibitors deserve further investigation for the treatment of LSD1 overexpressing cancer.

-
A novel series of melanin concentrating hormone receptor 1 (MCHr1) antagonists were the starting point for a drug discovery program that culminated in the discovery of 103 (AZD1979). The lead optimization program was conducted with a focus on reducing lipophilicity and understanding the physicochemical properties governing CNS exposure and undesired off-target pharmacology such as hERG interactions. An integrated approach was taken where the key assay was ex vivo receptor occupancy in mice. The candidate compound 103 displayed appropriate lipophilicity for a CNS indication and showed excellent permeability with no efflux. Preclinical GLP toxicology and safety pharmacology studies were without major findings and 103 was taken into clinical trials.

- Synthesis and biological evaluation of 5-benzylidenepyrimidine-2,4,6(1H,3H, 5H)-trione derivatives for the treatment of obesity-related nonalcoholic fatty liver disease
-
Nonalcoholic fatty liver disease (NAFLD), one of chronic liver diseases, seems to be rising as the obesity epidemic continues. In this study, 54 novel (thio)barbituric acid derivatives have been synthesized and evaluated for pharmacological activity. 7h exhibited potent glucose-lowering effects on insulin-resistant HepG2 cells and regulated adiponectin and leptin expression in 3T3-L1 adipocytes. Oral administration of 7h at 25 mg kg-1 day -1 for 4 weeks improved the progression of high fat diet-induced NAFLD by reducing the weight of body, liver, and fat, as well as modulating serum levels of fasting glucose, insulin, triglycerides, LDL-c, ALT, adiponectin and hepatic contents of triglycerides, total cholesterol. H&E stainings revealed that 7h blocked fat deposition in liver and the increase of adipocyte number and size in adipose tissues from NAFLD. Furthermore, treatment with 7h alleviated the obese clinical symptoms, recovered serum biomarkers to appropriate ranges, and improved glucose tolerance by OGTT and IGTT in DIO mice.
