Potent and selective ferroptosis regulators promote an intensive understanding of the regulation and mechanisms underlying ferroptosis, which is highly associated with various diseases. In this study, through a stepwise structure optimization, a potent and selective ferroptosis inducer was developed targeting to inhibit glutathione peroxidase 4 (GPX4), and the structure-activity relationship (SAR) of these compounds was uncovered. Compound26aexhibited outstanding GPX4 inhibitory activity with a percent inhibition up to 71.7% at 1.0 μM compared to 45.9% of RSL-3. At the cellular level,26acould significantly induce lipid peroxide (LPO) increase and effectively induce ferroptosis with satisfactory selectivity (the value of 31.5). The morphological analysis confirmed the ferroptosis induced by26a. Furthermore,26asignificantly restrained tumor growth in a mouse 4T1 xenograft model without obvious toxicity.

Paragraph 0863; 0864, (2015/06/03)
A compound represented by formula (1) (in the formula: ring-D represents a three- to eight-membered hydrocarbon ring; Ra represents an optionally substituted amino C1-6 alkyl group or the like; Rb1 and Rb2 each independently represent a hydrogen atom, a halogen atom, or the like; Rc represents an optionally substituted C6-10 aryl group or the like; Rd represents a hydrogen atom or the like; and ring-Q represents a (hetero)aryl group or the like which may be substituted with a carboxyl group or the like) or a pharmaceutically acceptable salt thereof exhibits an excellent FXIa inhibitory activity, and is useful as a therapeutic agent against thrombosis or the like.

A number of isosteres (oxadiazoles, thiadiazoles, tetrazoles and diazines) of benzocaine were prepared and evaluated for their capacity to induce methemoglobinemia - with a view to their possible application as humane pest control agents. It was found that an optimal lipophilicity for the formation of methemoglobin (metHb) in vitro existed within each series, with 1,2,4-oxadiazole 3 (metHb% = 61.0 ± 3.6) and 1,3,4-oxadiazole 10 (metHb% = 52.4 ± 0.9) demonstrating the greatest activity. Of the 5 candidates (compounds 3, 10, 11, 13 and 23) evaluated in vivo, failure to induce a lethal end-point at doses of 120 mg/kg was observed in all cases. Inadequate metabolic stability, particularly towards hepatic enzymes such as the CYPs, was postulated as one reason for their failure.
