LDC7559 is a novel selective inhibitor of Gasdermin D (GSDMD)[1]. GSDMD is a pore-forming protein and an executor of pyroptosis[2]. LDC7559 can antagonize the depressive effects of acrylamide (AM) and improve chronic unpredictable mild stress (CUMS) depression in mice[3].
In vitro, pretreatment of A549 cells with LDC7559 (5μM) for 6h significantly reduced the release of intracellular lactate dehydrogenase (LDH) after irradiation and increased cell survival[4]. LDC7559 (10μM) treatment of mouse melanoma B16 cells for 24h significantly inhibited VSV-CHIKV (an oncolytic virus)-induced pyroptosis, reduced the protein level of GSDMD-N (the active form of the pyroptosis executor protein), and inhibited cell membrane rupture[5].
In vivo, LDC7559 (10, 20, 30mg/kg) was intraperitoneally injected into rats with subarachnoid hemorrhage (SAH) model, which alleviated the neurological deficits after SAH, inhibited microglial activation and inflammatory response, and suppressed neuronal pyroptosis and apoptosis as well as GSDMD-mediated signal transduction[6].

| Cell experiment [1]: | |
Cell lines | A549 cells |
Preparation Method | A549 cells were incubated with 5μM LDC7559 at 6h before irradiation. After 48h of irradiation, the levels of released LDH were detected as indicated. |
Reaction Conditions | 5μM; 6h |
Applications | LDC7559 significantly decreased LDH release in irradiated A549 cells. |
| Animal experiment [2]: | |
Animal models | Sprague-Dawley rats |
Preparation Method | Adult male Sprague-Dawley rats (weighing 230-280g) were used, rat model of subarachnoid hemorrhage (SAH) was built. Before SAH, anesthetization was administered with 1% sodium pentobarbital. A marked filament (4-0) was used to puncture the origin of the left middle cerebral artery. Sham-operated rats received the same treatment, but not with vessel perforation. In vivo experiments, rats were randomly allotted to sham group (n=18), SAH+vehicle group (n=22, 4 animals died), SAH + LDC7559 group (n=60, 6 animals died), and SAH+LDC7559+nigericin group (n=21, 3 animals died). LDC7559 was diluted in 10% DMSO and 90% corn oil before use. LDC7559 (10, 20, or 30mg/kg) or vehicle was treated at 2h after SAH by intraperitoneally administration and then once a day. Nigericin (2mg) was prepared in 2mL ethanol and physiologic saline and was intracerebroventricularly administered at 2h before SAH. |
Dosage form | 10, 20, 30mg/kg; i.p. |
Applications | LDC7559 treatment alleviated neurological deficits after SAH, inhibited microglial activation and inflammatory response, suppressed neuronal pyroptosis and apoptosis, and suppressed GSDMD-mediated signaling. |
