Cycloheximide is an orally active antifungal antibiotic produced by Streptomyces griseus. Cycloheximide inhibits protein synthesis and RNA synthesis in vivo (IC50=532.5nM and 2880nM). Cycloheximide binds to the E site of the eukaryotic 60S ribosomal subunit to block eEF2-mediated translocation, thereby inhibiting protein synthesis. At the same time, Cycloheximide suppresses autophagy through activating the mTORC1 pathway. Cycloheximide can be used in studies related to protein half-life determination and translational regulation[1-4].
In vitro, Cycloheximide (10μg/ml) together with lipopolysaccharide (100ng/ml) acted on J774.1 macrophage-like cells for 4h. Cycloheximide induced apoptotic cell death. Cycloheximide blocked the production of p38 phosphatase through inhibiting protein synthesis, prolonged p38 phosphorylation signals, and triggered the death pathway[5]. Cycloheximide (0.35–100μM) treated human colon adenocarcinoma HT29-D4 cells for 48h. Cycloheximide dose-dependently increased the number of vasoactive intestinal peptide binding sites on the cell surface[6].
In vivo, Cycloheximide (10mg/kg; single injection) was subcutaneously injected into Swiss-Webster mice. Cycloheximide inhibited protein synthesis in the mouse brain and induced retention deficits of prior learning[7]. Cycloheximide (200mg/kg; single injection) was intraperitoneally injected into ICR mice. After 20min, kainic acid (0.1μg) was injected into the lateral ventricle. Cycloheximide significantly prevented kainic acid-induced memory impairment and hippocampal CA3 pyramidal cell death. Cycloheximide inhibited the elevation of p-ERK, p-JNK1, and p-CaMK II, the expression of c-Fos and c-Jun, and microglial activation caused by kainic acid[8].

| Cell experiment [1]: | |
|
Cell lines |
JA-4 cells (an LPS‑sensitive subline of murine macrophage‑like cell line J774.1) |
|
Preparation Method |
JA‑4 cells were maintained in Ham’s F‑10 medium supplemented with 10% heat‑inactivated fetal bovine serum, 50U/ml penicillin and 50μg/ml streptomycin at 37°C, 5% CO₂. Cells were seeded at 2×10⁵ cells/well in 24‑well plates overnight, then treated with or without 10ng/ml LPS for 90min, washed, and subsequently incubated with 100ng/ml LPS and 10μg/ml Cycloheximide for 4h. |
|
Reaction Conditions |
10μg/ml; 4h |
|
Applications |
Cycloheximide combined with LPS induced apoptotic cell death evidenced by PARP cleavage, DNA ladder formation, caspase‑3 activation, and LDH release. Sustained phosphorylation of p38 MAP kinase was observed and required for the cytotoxicity. Pretreatment with 10ng/ml LPS for 90min prevented the cytotoxicity, correlating with downregulated p38 phosphorylation. |
| Animal experiment [2]: | |
|
Animal models |
Male ICR mice (20-25g) |
|
Preparation Method |
Male ICR mice were intraperitoneally administered Cycloheximide at 200mg/kg 20min prior to intracerebroventricular (i.c.v.) injection of kainic acid (0.1μg/5μl). A one-trial step-through passive avoidance test was performed 24h after kainic acid administration, and mice were sacrificed at 30min (for p-ERK and p-JNK1 detection), 2h (for c-Fos and c-Jun detection) or 24h (for hippocampal CA3 neuronal death and OX-42 immunoreactivity detection) post kainic acid injection. |
|
Dosage form |
200mg/kg; i.p.; single injection |
|
Applications |
Cycloheximide pretreatment prevented kainic acid-induced memory impairment in the passive avoidance test, blocked kainic acid-induced pyramidal cell death in the hippocampal CA3 region, attenuated kainic acid-elevated phosphorylation of ERK in dentate gyrus and mossy fiber, phosphorylation of JNK1 and CaMK II in hippocampus, inhibited kainic acid-induced upregulation of c-Fos and c-Jun expression in hippocampus, and reduced kainic acid-induced increase of OX-42 immunoreactivity in hippocampal CA3 region. |
